practices in selected tourist attractions in Bauchi state, Nigeria. Four tourist attractions were used for the research. Checklists were used to assess operations and repairs maintenance practices in the different attractions. The study carried out personal assessment thrice in six months without prior knowledge of the staff in charge for operational maintenance. Records of repairs maintenance from the attractions maintenance unit for a period of ten years were assessed using the checklists. The findings of the study show that operations maintenance was not adequately carried out in the four tourists attractions. Repairs maintenance was carried out in Yankari game reserve and safari, but repairs maintenance was poor in the other three attractions. The study therefore, recommends that adequate maintenance should be practiced in tourist attractions to expand the lifespan of the facilities and also encourage tourist patronage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=appraisal" title="appraisal">appraisal</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=practices" title=" practices"> practices</a>, <a href="https://publications.waset.org/abstracts/search?q=tourist%20attraction" title=" tourist attraction"> tourist attraction</a> </p> <a href="https://publications.waset.org/abstracts/31847/appraisal-of-maintenance-practices-in-selected-tourist-attraction-in-bauchi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31847.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">300</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3127</span> An Assessment of Airport Collaborative Decision-Making System Using Predictive Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faruk%20Aras">Faruk Aras</a>, <a href="https://publications.waset.org/abstracts/search?q=Melih%20Inal"> Melih Inal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tansel%20Cinar"> Tansel Cinar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The coordination of airport staff especially in the operations and maintenance departments is important for the airport operation. As a result, this coordination will increase the efficiency in all operation. Therefore, a Collaborative Decision-Making (CDM) system targets on improving the overall productivity of all operations by optimizing the use of resources and improving the predictability of actions. Enlarged productivity can be of major benefit for all airport operations. It also increases cost-efficiency. This study explains how predictive maintenance using IoT (Internet of Things), predictive operations and the statistical data such as Mean Time To Failure (MTTF) improves airport terminal operations and utilize airport terminal equipment in collaboration with collaborative decision making system/Airport Operation Control Center (AOCC). Data generated by the predictive maintenance methods is retrieved and analyzed by maintenance managers to predict when a problem is about to occur. With that information, maintenance can be scheduled when needed. As an example, AOCC operator would have chance to assign a new gate that towards to this gate all the equipment such as travellator, elevator, escalator etc. are operational if the maintenance team is in collaboration with AOCC since maintenance team is aware of the health of the equipment because of predictive maintenance methods. Applying predictive maintenance methods based on analyzing the health of airport terminal equipment dramatically reduces the risk of downtime by on time repairs. We can classify the categories as high priority calls for urgent repair action, as medium priority requires repair at the earliest opportunity, and low priority allows maintenance to be scheduled when convenient. In all cases, identifying potential problems early resulted in better allocation airport terminal resources by AOCC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport" title="airport">airport</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title=" predictive maintenance"> predictive maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20decision-making%20system" title=" collaborative decision-making system"> collaborative decision-making system</a>, <a href="https://publications.waset.org/abstracts/search?q=Airport%20Operation%20Control%20Center%20%28AOCC%29" title=" Airport Operation Control Center (AOCC)"> Airport Operation Control Center (AOCC)</a> </p> <a href="https://publications.waset.org/abstracts/84719/an-assessment-of-airport-collaborative-decision-making-system-using-predictive-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84719.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3126</span> Analysis of Maintenance Operations in an Industrial Bakery Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Savsar">Mehmet Savsar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a practical case application of simulation modeling and analysis in a specific industrial setting.

The rail-track system consists of several types of components, such as rail, ballast, and switches with different preventive maintenance and renewal intervals. To perform maintenance or renewal on the track, a train free period for maintenance, called a possession, is required. Since a major possession directly affects the regular train schedule, maintenance and renewal activities are clustered as much as possible. In a highly dense and utilized railway network, the possession time on the track is critical since the demand for train operations is very high and a long possession has a severe impact on the regular train schedule. We present an optimization model and investigate the maintenance schedules with and without the possession capacity constraint. In addition, we also integrate the social-economic cost related to the effects of the maintenance time to the variable possession cost into the optimization model. A numerical example is provided to illustrate the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rail-track%20components" title="rail-track components">rail-track components</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20clustering" title=" optimal clustering"> optimal clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=possession%20capacity" title=" possession capacity"> possession capacity</a> </p> <a href="https://publications.waset.org/abstracts/69824/optimal-maintenance-clustering-for-rail-track-components-subject-to-possession-capacity-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69824.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3124</span> A Hybrid Data Mining Algorithm Based System for Intelligent Defence Mission Readiness and Maintenance Scheduling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shivam%20Dwivedi">Shivam Dwivedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumit%20Prakash%20Gupta"> Sumit Prakash Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Durga%20Toshniwal"> Durga Toshniwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is a challenging task in today’s date to keep defence forces in the highest state of combat readiness with budgetary constraints. A huge amount of time and money is squandered in the unnecessary and expensive traditional maintenance activities. To overcome this limitation Defence Intelligent Mission Readiness and Maintenance Scheduling System has been proposed, which ameliorates the maintenance system by diagnosing the condition and predicting the maintenance requirements. Based on new data mining algorithms, this system intelligently optimises mission readiness for imminent operations and maintenance scheduling in repair echelons. With modified data mining algorithms such as Weighted Feature Ranking Genetic Algorithm and SVM-Random Forest Linear ensemble, it improves the reliability, availability and safety, alongside reducing maintenance cost and Equipment Out of Action (EOA) time. The results clearly conclude that the introduced algorithms have an edge over the conventional data mining algorithms. The system utilizing the intelligent condition-based maintenance approach improves the operational and maintenance decision strategy of the defence force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition%20based%20maintenance" title="condition based maintenance">condition based maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=defence%20maintenance" title=" defence maintenance"> defence maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble" title=" ensemble"> ensemble</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title=" genetic algorithms"> genetic algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20scheduling" title=" maintenance scheduling"> maintenance scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=mission%20capability" title=" mission capability"> mission capability</a> </p> <a href="https://publications.waset.org/abstracts/73229/a-hybrid-data-mining-algorithm-based-system-for-intelligent-defence-mission-readiness-and-maintenance-scheduling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73229.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3123</span> Scheduled Maintenance and Downtime Cost in Aircraft Maintenance Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Remzi%20Saltoglu">Remzi Saltoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazmia%20Humaira"> Nazmia Humaira</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Inalhan"> Gokhan Inalhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During aircraft maintenance scheduling, operator calculates the budget of the maintenance. Usually, this calculation includes only the costs that are directly related to the maintenance process such as cost of labor, material, and equipment. In some cases, overhead cost is also included. However, in some of those, downtime cost is neglected claiming that grounding is a natural fact of maintenance; therefore, it is not considered as part of the analytical decision-making process. Based on the normalized data, we introduce downtime cost with its monetary value and add its seasonal character. We envision that the rest of the model, which works together with the downtime cost, could be checked with the real life cases, through the review of MRO cost and airline spending in the particular and scheduled maintenance events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft%20maintenance" title="aircraft maintenance">aircraft maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=downtime" title=" downtime"> downtime</a>, <a href="https://publications.waset.org/abstracts/search?q=downtime%20cost" title=" downtime cost"> downtime cost</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20cost" title=" maintenance cost"> maintenance cost</a> </p> <a href="https://publications.waset.org/abstracts/47046/scheduled-maintenance-and-downtime-cost-in-aircraft-maintenance-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47046.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3122</span> Feasibility Study for the Implementation of a Condition-Based Maintenance System in the UH-60 Helicopters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santos%20Cabrera">Santos Cabrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Halbert%20Yesid"> Halbert Yesid</a>, <a href="https://publications.waset.org/abstracts/search?q=Moncada%20Nino"> Moncada Nino</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvaro%20Fernando"> Alvaro Fernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Rincon%20Cuta"> Rincon Cuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeisson%20Alexis"> Yeisson Alexis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work evaluates the feasibility of implementing a health and use monitoring system (HUMS), based on vibration analysis as a condition-based maintenance program for the UH60L 'Blackhawk' helicopters. The mixed approach used consists of contributions from national and international experts, the analysis of data extracted from the software (Meridium), the correlation of variables derived from the diagnosis of availability, the development, and application of the HUMS system, the evaluation of the latter through of the use of instruments designed for the collection of information using the DELPHI method and data capture with the device installed in the helicopter studied. The results obtained in the investigation reflect the context of maintenance in aerial operations, a reduction of operation and maintenance costs of over 2%, better use of human resources, improvement in availability (5%), and fulfillment of the aircraft’s security standards, enabling the implementation of the monitoring system (HUMS) in the condition-based maintenance program. New elements are added to the study of maintenance based on condition -specifically, in the determination of viability based on qualitative and quantitative data according to the methodology. The use of condition-based maintenance will allow organizations to adjust and reconfigure their strategic, logistical, and maintenance capabilities, aligning them with their strategic objectives of responding quickly and adequately to changes in the environment and operational requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20transportation%20sustainability" title="air transportation sustainability">air transportation sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=HUMS" title=" HUMS"> HUMS</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20based%20condition" title=" maintenance based condition"> maintenance based condition</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20blackhawk%20capability" title=" maintenance blackhawk capability"> maintenance blackhawk capability</a> </p> <a href="https://publications.waset.org/abstracts/135423/feasibility-study-for-the-implementation-of-a-condition-based-maintenance-system-in-the-uh-60-helicopters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135423.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3121</span> Intelligent IT Infrastructure in the Gas and Oil Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Fahad%20Alotaibi">Ahmad Fahad Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Hamed%20Hajri"> Khalid Hamed Hajri</a>, <a href="https://publications.waset.org/abstracts/search?q=Humoud%20Hudiban%20Rashidi"> Humoud Hudiban Rashidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Intelligent information technology infrastructure is considered one of the enablers to enhance digital transformation in the gas and oil fields to optimize IT infrastructure reliability by supporting operations and maintenance in a safe and secure method to optimize resources.

Three salient issues require to be addressed for an asset-intensive organization to employ an MPM-based framework to optimize maintenance. Firstly, the organization should establish important perfomance metric(s), in this case the maintenance objective(s), which they will be focuss on. The second issue entails aligning the maintenance objective(s) with maintenance optimization. This is achieved by deriving maintenance performance indicators that subsequently form an objective function for the optimization program. Lastly, the objective function is employed in an optimization program to derive maintenance decision support. In this study, we develop a framework that initially identifies the crucial maintenance performance measures, and employs them to derive maintenance decision support. The proposed framework is demonstrated in a case study of a geothermal drilling rig, where the objective function is evaluated utilizing a simulation-based model whose parameters are derived from empirical maintenance data. Availability, reliability and maintenance inventory are depicted as essential objectives requiring further attention. A simulation model is developed mimicking a drilling rig operations and maintenance where the sub-systems are modelled undergoing imperfect maintenance, corrective (CM) and preventive (PM), with the total cost as the primary performance measurement. Moreover, three maintenance spare inventory policies are considered; classical (retaining stocks for a contractual period), vendor-managed inventory with consignment stock and periodic monitoring order-to-stock (s, S) policy. Optimization results infer that the adoption of (s, S) inventory policy, increased PM interval and reduced reliance of CM actions offers improved availability and total costs reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maintenance" title="maintenance">maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=vendor-managed" title=" vendor-managed"> vendor-managed</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support" title=" decision support"> decision support</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/107472/maintenance-performance-measurement-derived-optimization-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107472.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3119</span> Optimizing SCADA/RTU Control System Alarms for Gas Wells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ali%20Faqeeh">Mohammed Ali Faqeeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SCADA System Alarms Optimization Process has been introduced recently and applied accordingly in different implemented stages. First, MODBUS communication protocols between RTU/SCADA were improved at the level of I/O points scanning intervals. Then, some of the technical issues related to manufacturing limitations were resolved. Afterward, another approach was followed to take a decision on the configured alarms database. So, a couple of meetings and workshops were held among all system stakeholders, which resulted in an agreement of disabling unnecessary (Diagnostic) alarms. Moreover, a leap forward step was taken to segregate the SCADA Operator Graphics in a way to show only process-related alarms while some other graphics will ensure the availability of field alarms related to maintenance and engineering purposes. This overall system management and optimization have resulted in a huge effective impact on all operations, maintenance, and engineering. It has reduced unneeded open tickets for maintenance crews which led to reduce the driven mileages accordingly. Also, this practice has shown a good impression on the operation reactions and response to the emergency situations as the SCADA operators can be staying much vigilant on the real alarms rather than gets distracted by noisy ones. SCADA System Alarms Optimization process has been executed utilizing all applicable in-house resources among engineering, maintenance, and operations crews. The methodology of the entire enhanced scopes is performed through various stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SCADA" title="SCADA">SCADA</a>, <a href="https://publications.waset.org/abstracts/search?q=RTU%20Communication" title=" RTU Communication"> RTU Communication</a>, <a href="https://publications.waset.org/abstracts/search?q=alarm%20management%20system" title=" alarm management system"> alarm management system</a>, <a href="https://publications.waset.org/abstracts/search?q=SCADA%20alarms" title=" SCADA alarms"> SCADA alarms</a>, <a href="https://publications.waset.org/abstracts/search?q=Modbus" title=" Modbus"> Modbus</a>, <a href="https://publications.waset.org/abstracts/search?q=DNP%20protocol" title=" DNP protocol"> DNP protocol</a> </p> <a href="https://publications.waset.org/abstracts/142519/optimizing-scadartu-control-system-alarms-for-gas-wells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3118</span> Comparison of Two Maintenance Policies for a Two-Unit Series System Considering General Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedvahid%20Najafi">Seyedvahid Najafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Viliam%20Makis"> Viliam Makis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, maintenance optimization has attracted special attention due to the growth of industrial systems complexity. Maintenance costs are high for many systems, and preventive maintenance is effective when it increases operations' reliability and safety at a reduced cost. The novelty of this research is to consider general repair in the modeling of multi-unit series systems and solve the maintenance problem for such systems using the semi-Markov decision process (SMDP) framework. We propose an opportunistic maintenance policy for a series system composed of two main units. Unit 1, which is more expensive than unit 2, is subjected to condition monitoring, and its deterioration is modeled using a gamma process. Unit 1 hazard rate is estimated by the proportional hazards model (PHM), and two hazard rate control limits are considered as the thresholds of maintenance interventions for unit 1. Maintenance is performed on unit 2, considering an age control limit. The objective is to find the optimal control limits and minimize the long-run expected average cost per unit time. The proposed algorithm is applied to a numerical example to compare the effectiveness of the proposed policy (policy Ⅰ) with policy Ⅱ, which is similar to policy Ⅰ, but instead of general repair, replacement is performed. Results show that policy Ⅰ leads to lower average cost compared with policy Ⅱ.  <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condition-based%20maintenance" title="condition-based maintenance">condition-based maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=proportional%20hazards%20model" title=" proportional hazards model"> proportional hazards model</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-Markov%20decision%20process" title=" semi-Markov decision process"> semi-Markov decision process</a>, <a href="https://publications.waset.org/abstracts/search?q=two-unit%20series%20systems" title=" two-unit series systems"> two-unit series systems</a> </p> <a href="https://publications.waset.org/abstracts/122252/comparison-of-two-maintenance-policies-for-a-two-unit-series-system-considering-general-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122252.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3117</span> Neural Network Based Approach of Software Maintenance Prediction for Laboratory Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vuk%20M.%20Popovic">Vuk M.

After that, any modification to it corresponds to maintenance. Software maintenance involves modifications to keep a software project usable in a changed or a changing environment, to correct discovered faults, and modifications, and to improve performance or maintainability. Software maintenance and management of software maintenance are recognized as two most important and most expensive processes in a life of a software product. This research is basing the prediction of maintenance, on risks and time evaluation, and using them as data sets for working with neural networks. The aim of this paper is to provide support to project maintenance managers. They will be able to pass the issues planned for the next software-service-patch to the experts, for risk and working time evaluation, and afterward to put all data to neural networks in order to get software maintenance prediction. This process will lead to the more accurate prediction of the working hours needed for the software-service-patch, which will eventually lead to better planning of budget for the software maintenance projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laboratory%20information%20system" title="laboratory information system">laboratory information system</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20engineering" title=" maintenance engineering"> maintenance engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20maintenance" title=" software maintenance"> software maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20maintenance%20costs" title=" software maintenance costs"> software maintenance costs</a> </p> <a href="https://publications.waset.org/abstracts/68789/neural-network-based-approach-of-software-maintenance-prediction-for-laboratory-information-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68789.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3116</span> The Impacts of Technology on Operations Costs: The Mediating Role of Operation Flexibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fazli%20Idris">Fazli Idris</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihad%20Mohammad"> Jihad Mohammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aims to determine the impact of technology and service operations flexibility, which is divided into external flexibility and internal robustness, on operations costs.

Such a vital process is important to be proactively considered during equipment design and manufacturing phases by removing and eliminating any obstacles in the equipment which adversely affect the (O&M) activities. This paper presents a gap analysis pertaining to difficulties in performing operations and maintenance (O&M) high voltage electrical equipment, includes power transformers, switch gears, motor control center, disconnect switches and circuit breakers. The difficulties are gathered from field personnel, equipment design review comments, quality management system, and lessons learned database. The purpose of the gap analysis is to mitigate and prevent the (O&M) difficulties as early as possible in the design stage of the equipment lifecycle. The paper concludes with several recommendations and corrective actions for all identified gaps in order to reduce the cost (O&M) difficulties and improve the equipment lifecycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=operation%20and%20maintenance" title="operation and maintenance">operation and maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20equipment" title=" high voltage equipment"> high voltage equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=equipment%20lifecycle" title=" equipment lifecycle"> equipment lifecycle</a>, <a href="https://publications.waset.org/abstracts/search?q=reduce%20the%20cost%20of%20maintenance" title=" reduce the cost of maintenance"> reduce the cost of maintenance</a> </p> <a href="https://publications.waset.org/abstracts/152881/mitigation-of-high-voltage-equipment-design-deficiencies-for-improved-operation-and-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152881.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3114</span> Lean Philosophy towards the Enhancement of Maintenance Programs Efficiency with Particular Attention to Libyan Oil and Gas Scenario</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulayman%20Adrees%20Mohammed">Sulayman Adrees Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Faraj%20Abd%20Alsameea"> Ahmed Faraj Abd Alsameea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ongoing hindrance for Libyan oil and gas companies is the persistent challenge of eradicating maintenance program failures that result in exorbitant costs and production setbacks.

Three pavements are tested, and a total number of 1.800 snowplow scrapings are applied. The skid resistance of the pavements is measured periodically using two indicators on two scales: an average profile depth (macrotexture) and a longitudinal friction coefficient (microtexture). The results of these tests show a reduction in the average profile depth between 4 % and 10 %, depending on the asphalt composition. This reduction of macrotexture is correlated with the reduction of high points on surfaces due to the removal of portions of the aggregate surfaces. The longitudinal friction coefficient of pavements decreases by 4% to 10%. This reduction in microtexture is related to the polishing of the surface of the aggregate used in the pavements. These variations of skid resistance are not linear. A phenomenon of regeneration of the friction coefficient is observed for pavements composed of sand-lime aggregates after several scraping operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GripTester" title="GripTester">GripTester</a>, <a href="https://publications.waset.org/abstracts/search?q=macrotexture" title=" macrotexture"> macrotexture</a>, <a href="https://publications.waset.org/abstracts/search?q=microtexture" title=" microtexture"> microtexture</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=skid%20resistance" title=" skid resistance"> skid resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=snowplow" title=" snowplow"> snowplow</a>, <a href="https://publications.waset.org/abstracts/search?q=TM2" title=" TM2"> TM2</a>, <a href="https://publications.waset.org/abstracts/search?q=winter%20road%20maintenance" title=" winter road maintenance"> winter road maintenance</a> </p> <a href="https://publications.waset.org/abstracts/183005/evaluation-of-the-impact-of-scraping-operations-during-winter-road-maintenance-on-pavement-skid-resistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3111</span> Aircraft Line Maintenance Equipped with Decision Support System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Sudarsan%20Baskar">B.

These analyses showed that instead of buying new machines and increasing costs in order to promote capacity, the improving of MTBF and MTTR indexes would solve capacity problems in the best way and decrease costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Golgohar%20Iron%20Ore%20Mining%20and%20Industrial%20Company" title="Golgohar Iron Ore Mining and Industrial Company">Golgohar Iron Ore Mining and Industrial Company</a>, <a href="https://publications.waset.org/abstracts/search?q=maintainability" title=" maintainability"> maintainability</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20costs" title=" maintenance costs"> maintenance costs</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability-center-maintenance" title=" reliability-center-maintenance"> reliability-center-maintenance</a> </p> <a href="https://publications.waset.org/abstracts/75164/providing-a-practical-model-to-reduce-maintenance-costs-a-case-study-in-golgohar-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75164.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3109</span> Strategic Maintenance Management of Built Facilities in an Organisation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anita%20D.%20Adamu">Anita D.

It has now assumed a strategic position in many organisations that have recognised its importance in achieving primary goals and a key aspect of effective management of facilities. This paper aims at providing an understanding of the role and function of strategic management in creating and sustaining an effective maintenance management system in an organisation. The background provides an articulated concept and principles of strategic management. The theoretical concepts paved way for a conceptual framework for which strategic management can be integrated into the maintenance management system of an organisation to improve effectiveness in the maintenance of facilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facilities" title="facilities">facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20management" title=" maintenance management"> maintenance management</a>, <a href="https://publications.waset.org/abstracts/search?q=organisations" title=" organisations"> organisations</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20management" title=" strategic management"> strategic management</a> </p> <a href="https://publications.waset.org/abstracts/40969/strategic-maintenance-management-of-built-facilities-in-an-organisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">409</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3108</span> Sustainable Maintenance Model for Infrastructure in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Hasan">S.

An assessment model of sustainable maintenance for highway infrastructure projects in Egypt is developed in this paper. It helps in improving the implementation of sustainable maintenance criteria. Thus, this paper has applied the analytical hierarchy processes (AHP) to rank and explore the weight of 26 assessment indicators using three hierarchy levels containing the main sustainable categories and subcategories with related indicators. Overall combined weight of each indicator for sustainable maintenance evaluation has been calculated to sum up to a sustainable maintenance performance index (SMI). The results show that the factor "Preventive maintenance cost" has the highest relative contribution factor among others (13.5%), while two factors of environmental performance have the least weights (0.7%). The developed model aims to provide decision makers with information about current maintenance performance and support them in the decision-making process regarding future directions of maintenance activities. It can be used as an assessment performance tool during the operation and maintenance stage. The developed indicators can be considered during designing the maintenance plan. Practices for successful implementation of the model are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title="analytical hierarchy process">analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment%20performance%20Model" title=" assessment performance Model"> assessment performance Model</a>, <a href="https://publications.waset.org/abstracts/search?q=KPIs%20for%20sustainable%20maintenance" title=" KPIs for sustainable maintenance"> KPIs for sustainable maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20maintenance%20index" title=" sustainable maintenance index"> sustainable maintenance index</a> </p> <a href="https://publications.waset.org/abstracts/127136/sustainable-maintenance-model-for-infrastructure-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127136.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3107</span> Reliability-Centered Maintenance Application for the Development of Maintenance Strategy for a Cement Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Hameed%20Al-Farsi">Nabil Hameed Al-Farsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study’s main goal is to develop a model and a maintenance strategy for a cement factory called Arabian Cement Company, Rabigh Plant. The proposed work here depends on Reliability centric maintenance approach to develop a strategy and maintenance schedule that ensures increasing the reliability of the production system components, thus ensuring continuous productivity. The cost-effective maintenance of the plant’s dependability performance is the key goal of durability-based maintenance is. The cement plant consists of 7 important steps, so, developing a maintenance plan based on Reliability centric maintenance (RCM) method is made up of 10 steps accordingly starting from selecting units and data until performing and updating the model. The processing unit chosen for the analysis of this case is the calcinatory unit regarding model’s validation and the Travancore Titanium Products Ltd (TTP) using the claimed data history acquired from the maintenance department maintenance from the mentioned company. After applying the proposed model, the results of the maintenance simulation justified the plant's existing scheduled maintenance policy being reconsidered. Results represent the need for preventive maintenance for all Class A criticality equipment instead of the planned maintenance and the breakdown one for all other equipment depends on its criticality and an FMEA report. Consequently, the additional cost of preventive maintenance would be offset by the cost savings from breakdown maintenance for the remaining equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering" title="engineering">engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20modes" title=" failure modes"> failure modes</a>, <a href="https://publications.waset.org/abstracts/search?q=effects%20and%20criticality%20analysis%20%28FMEA%29" title=" effects and criticality analysis (FMEA)"> effects and criticality analysis (FMEA)</a> </p> <a href="https://publications.waset.org/abstracts/146390/reliability-centered-maintenance-application-for-the-development-of-maintenance-strategy-for-a-cement-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146390.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3106</span> Investigating the Causes of Human Error-Induced Incidents in the Maintenance Operations of Petrochemical Industry by Using Human Factors Analysis and Classification System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omid%20Kalatpour">Omid Kalatpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Ajdari"> Mohammadreza Ajdari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article studied the possible causes of human error-induced incidents in the petrochemical industry maintenance activities by using Human Factors Analysis and Classification System (HFACS). The purpose of the study was anticipating and identifying these causes and proposing corrective and preventive actions. Maintenance department in a petrochemical company was selected for research. A checklist of human error-induced incidents was developed based on four HFACS main levels and nineteen sub-groups. Hierarchical task analysis (HTA) technique was used to identify maintenance activities and tasks. The main causes of possible incidents were identified by checklist and recorded. Corrective and preventive actions were defined depending on priority. Analyzing the worksheets of 444 activities in four levels of HFACS showed 37.6% of the causes were at the level of unsafe actions, 27.5% at the level of unsafe supervision, 20.9% at the level of preconditions for unsafe acts and 14% of the causes were at the level of organizational effects. The HFACS sub-groups showed errors (24.36%) inadequate supervision (14.89%) and violations (13.26%) with the most frequency. According to findings of this study, increasing the training effectiveness of operators and supervision improvement respectively are the most important measures in decreasing the human error-induced incidents in petrochemical industry maintenance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20error" title="human error">human error</a>, <a href="https://publications.waset.org/abstracts/search?q=petrochemical%20industry" title=" petrochemical industry"> petrochemical industry</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=HFACS" title=" HFACS"> HFACS</a> </p> <a href="https://publications.waset.org/abstracts/73355/investigating-the-causes-of-human-error-induced-incidents-in-the-maintenance-operations-of-petrochemical-industry-by-using-human-factors-analysis-and-classification-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">242</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3105</span> Maintenance Management Practice for Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harold%20Jideofor%20Nnachetam">Harold Jideofor Nnachetam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maintenance management in Nigeria Polytechnic faced many issues due to poor service delivery, inadequate finance, and poor maintenance plan and maintenance backlogs. The purpose of this study is to improve the conventional method practices which tend to be ineffective in Nigeria Polytechnic. The case study was conducted with eight Polytechnics in Nigeria. The selected Polytechnic is based on conventional method practices and its major problems, attempt to implement computerized technology and the willingness of staff to share their experiences. All feedbacks from respondents through semi-structured interview were recorded using video camera and transcribed verbatim. The overall findings of this research indicated; poor service delivery, inadequate financial, poor maintenance planning and maintenance backlogs. There is also need to overcome less man power competencies of maintenance management practices which existed with all eight Polytechnics. In addition, the study also found that the Polytechnics still use conventional maintenance management processes in managing building facility condition. As a result, the maintenance management staff was not able to improve the maintenance management performance at the Polytechnics. The findings are intended to be used for maintenance management practices at Nigeria Polytechnics in order to provide high-quality of building facility with safe and healthy environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maintenance%20management" title="maintenance management">maintenance management</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20method" title=" conventional method"> conventional method</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20management%20system" title=" maintenance management system"> maintenance management system</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria%20polytechnic" title=" Nigeria polytechnic"> Nigeria polytechnic</a> </p> <a href="https://publications.waset.org/abstracts/33471/maintenance-management-practice-for-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33471.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3104</span> Educational Plan and Program of the Subject: Maintenance of Electric Power Equipment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rade%20M.%20Ciric">Rade M.

As part of Nama group, Oman Electricity Transmission Company (OETC) was the first company to implement this system. It was very important for OETC to implement and maintain such a system to achieve its business objectives and for effective operations, which will also support the delivery of the asset management strategy. Enterprise Asset Management (eAM) addresses the comprehensive asset maintenance requirements of Oman Electricity Transmission Company (OETC). OETC needs to optimize capacity and increase utilization, while lowering unit production. E-AM will enable OETC to adopt this strategy. Implementation of e-AM has improved operation performance with preventive and scheduled maintenance as well as it increased safety. Implementation of e-AM will also enable OETC to create optimal asset management strategy which will increase revenue and decrease cost by effectively monitoring operational data such as maintenance history and operation conditions. CMMS (Computerised Maintenance Management System) is the main software and the back-bone of e-AM system. It is used to provide an improved working practice to properly establish information and data flow related to maintenance activities. Implementation of e-AM system was one of the factors that supported OETC to achieve ISO55001 Certificate on fourth quarter of 2016. Also, full implementation of e-AM system will result in strong integration between CMMS and Geographical Information Systems (GIS) application and it will improve OETC to build a reliable maintenance strategy for all asset classes in its Transmission network. In this paper we will share our experience and knowledge of implementing such a system and how it supported OETC’s management to make decisions. Also we would highlight the challenges and difficulties that we encountered during the implementation of e-AM. Also, we will list some features and advantages of e-AM in asset management, preventive maintenance and maintenance cost management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMMS" title="CMMS">CMMS</a>, <a href="https://publications.waset.org/abstracts/search?q=Maintenance%20Management" title=" Maintenance Management"> Maintenance Management</a>, <a href="https://publications.waset.org/abstracts/search?q=Asset%20Management" title=" Asset Management"> Asset Management</a>, <a href="https://publications.waset.org/abstracts/search?q=Maintenance%20Strategy" title=" Maintenance Strategy"> Maintenance Strategy</a> </p> <a href="https://publications.waset.org/abstracts/127909/implementation-of-enterprise-asset-management-e-am-system-at-oman-electricity-transmission-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3102</span> Contribution to the Decision-Making Process for Selecting the Suitable Maintenance Policy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Y.%20Mahamoud">Nasser Y.

A decision-support methodology to choose a maintenance policy (corrective, systematic or conditional preventive, predictive, opportunistic or not) is proposed to facilitate this choice using the main categories of the most important decision criteria. The different steps of this methodology are illustrated using theoretical case: identification of the different maintenance alternatives, determining the structure of the most important categories of the decision criteria, assessing the different maintenance policies on to the criteria by using an ordinal preference relation, and finally ranking the different maintenance policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maintenance%20policy" title="maintenance policy">maintenance policy</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20criteria" title=" decision criteria"> decision criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making%20process" title=" decision-making process"> decision-making process</a>, <a href="https://publications.waset.org/abstracts/search?q=AHP" title=" AHP"> AHP</a> </p> <a href="https://publications.waset.org/abstracts/72202/contribution-to-the-decision-making-process-for-selecting-the-suitable-maintenance-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72202.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3101</span> Pavement Maintenance and Rehabilitation Scheduling Using Genetic Algorithm Based Multi Objective Optimization Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashwini%20Gowda%20K.%20S">Ashwini Gowda K.

Facilitating onerous maintenance activities is the only way to either maintain or enhance the value and contemporary standard of the premises. By the way, maintenance budget is always bounded by the corresponding threshold limit. In order to optimize the limited resources allocation in carrying out maintenance, there is a substantial need to prioritize maintenance work. This paper reveals the application of Fuzzy AHP in a Facilities Management Company determining the maintenance priorities on the basis of predetermined criteria, viz., Building Status (BS), Effects on Fabrics (EF), Effects on Sustainability (ES), Effects on Users (EU), Importance of Usage (IU) and Physical Condition (PC) in dealing with categorized 8 predominant building components maintenance aspects for building premises. From the case study, it is found that ‘building exterior repainting or re-tiling’, ‘spalling concrete repair works among exterior area’ and ‘lobby renovation’ are the top three maintenance priorities from facilities manager and maintenance expertise personnel. Through the application of the Fuzzy AHP for maintenance priorities decision algorithm, a more systemic and easier comparing scalar linearity factors being explored even in considering other multiple criteria decision scenarios of building maintenance issue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20maintenance" title="building maintenance">building maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20AHP" title=" fuzzy AHP"> fuzzy AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20priority" title=" maintenance priority"> maintenance priority</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20decision%20making" title=" multi-criteria decision making"> multi-criteria decision making</a> </p> <a href="https://publications.waset.org/abstracts/95951/a-fuzzy-analytic-hierarchy-process-approach-for-the-decision-of-maintenance-priorities-of-building-entities-a-case-study-in-a-facilities-management-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95951.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3099</span> A Case Study on Barriers in Total Productive Maintenance Implementation in the Abu Dhabi Power Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Alseiari">A.

Implementation of TPM programmes need strategic planning and there has been little research applied in this area within Middle-East power plants. In the power sector of Abu Dhabi, technologically and strategically, the power industry is extremely important, and it thus needs effective and efficient equipment management support. The aim of this paper is to investigate barriers to successful TPM implementation in the Abu Dhabi power industry. The study has been conducted in the context of a leading power company in the UAE. Semi-structured interviews were conducted with 16 employees, including maintenance and operation staff, and senior managers. The findings of this research identified seven key barriers, thus: managerial; organisational; cultural; financial; educational; communications; and auditing. With respect to the understanding of these barriers and obstacles in TPM implementation, the findings can contribute towards improved equipment operations and maintenance in power organisations. <p
