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">6175</span> Designing a Tool for Software Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ngah">Amir Ngah</a>, <a href="https://publications.waset.org/abstracts/search?q=Masita%20Abdul%20Jalil"> Masita Abdul Jalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Zailani%20Abdullah"> Zailani Abdullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of software maintenance is to maintain the software system in accordance with advancement in software and hardware technology.

There are many techniques proposed by various researchers, but with the increasing complexity of the software lifecycle model, it is crucial to develop a flexible system which can cater for the factors which in result have an impact on the quality of the end product. These factors include properties of the software development process and the product along with its operation conditions. In this paper, a neural network (perceptron) based software quality prediction technique is proposed. Using this technique, the stakeholders can predict the quality of the resulting software during the early phases of the lifecycle saving time and resources on future elimination of design errors and costly maintenance. This technique can be brought into practical use using successful training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20quality" title="software quality">software quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=prediction" title=" prediction"> prediction</a> </p> <a href="https://publications.waset.org/abstracts/78014/multilayer-neural-network-and-fuzzy-logic-based-software-quality-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78014.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">317</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">6171</span> Management of Medical Equipment Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Madad">Gholamreza Madad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The role of medical equipment in modern advanced hospitals is irrefutable. Despite limited financial resources, developing countries have taken an uncontrollable manner to the purchase of complex and expensive equipment, although they have not taken good maintenance to keep these huge capitals. In our country, limited studies have indicated that the irregularities exist in the management of medical equipment maintenance. Research method: The research was done as a cross-sectional one, and in this study, a questionnaire was used to collect data in 10 hospitals. After distributing and collecting questionnaires in person, the collected data were analyzed using descriptive statistics and SPSS software. Research findings: According to the obtained results from the four dimensions of the management of medical equipment maintenance, only (maintenance planning) was in a moderate position and other components with a score of less than 50% were at a low level. There was a direct relationship between the total score of maintenance management and guidance points and coordination of medical equipment maintenance, and as well as the age of hospital managers. Discussion and conclusion: In sum, we can say that problems such as lack of skilled staff in medical engineering departments of hospitals, lack of funds and unaware of the authorities of medical engineering units to their duties have caused that the maintenance situation of medical equipment maintenance is in poor condition (near average). The low inexperience of the authorities of the unit has also contributed to this problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equipment" title="equipment">equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20equipment" title=" medical equipment"> medical equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitals" title=" hospitals"> hospitals</a> </p> <a href="https://publications.waset.org/abstracts/83982/management-of-medical-equipment-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83982.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">162</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">6170</span> Intelligent Platform for Photovoltaic Park Operation and Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Livera">Andreas Livera</a>, <a href="https://publications.waset.org/abstracts/search?q=Spyros%20Theocharides"> Spyros Theocharides</a>, <a href="https://publications.waset.org/abstracts/search?q=Michalis%20Florides"> Michalis Florides</a>, <a href="https://publications.waset.org/abstracts/search?q=Charalambos%20Anastassiou"> Charalambos Anastassiou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A main challenge in the quest for ensuring quality of operation, especially for photovoltaic (PV) systems, is to safeguard the reliability and optimal performance by detecting and diagnosing potential failures and performance losses at early stages or before the occurrence through real-time monitoring, supervision, fault detection, and predictive maintenance. The purpose of this work is to present the functionalities and results related to the development and validation of a software platform for PV assets diagnosis and maintenance. The platform brings together proprietary hardware sensors and software algorithms to enable the early detection and prediction of the most common and critical faults in PV systems. It was validated using field measurements from operating PV systems. The results showed the effectiveness of the platform for detecting faults and losses (e.g., inverter failures, string disconnections, and potential induced degradation) at early stages, forecasting PV power production while also providing recommendations for maintenance actions. Increased PV energy yield production and revenue can be thus achieved while also minimizing operation and maintenance (O&M) costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure%20detection%20and%20prediction" title="failure detection and prediction">failure detection and prediction</a>, <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=performance%20monitoring" title=" performance monitoring"> performance monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=platform" title=" platform"> platform</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendations" title=" recommendations"> recommendations</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title=" predictive maintenance"> predictive maintenance</a> </p> <a href="https://publications.waset.org/abstracts/185740/intelligent-platform-for-photovoltaic-park-operation-and-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185740.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">49</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">6169</span> Operational Software Maturity: An Aerospace Industry Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Gonz%C3%A1lez%20Mu%C3%B1oz">Raúl González Muñoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Shehab"> Essam Shehab</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Weinitzke"> Martin Weinitzke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Fowler"> Chris Fowler</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Baguley"> Paul Baguley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software applications have become crucial to the aerospace industry, providing a wide range of functionalities and capabilities used during the design, manufacturing and support of aircraft. However, as this criticality increases, so too does the risk for business operations when facing a software failure. Hence, there is a need for new methodologies to be developed to support aerospace companies in effectively managing their software portfolios, avoiding the hazards of business disruption and additional costs. This paper aims to provide a definition of operational software maturity, and how this can be used to assess software operational behaviour, as well as a view on the different aspects that drive software maturity within the aerospace industry. The key research question addressed is, how can operational software maturity monitoring assist the aerospace industry in effectively managing large software portfolios? This question has been addressed by conducting an in depth review of current literature, by working closely with aerospace professionals and by running an industry case study within a major aircraft manufacturer. The results are a software maturity model composed of a set of drivers and a prototype tool used for the testing and validation of the research findings. By utilising these methodologies to assess the operational maturity of software applications in aerospace, benefits in maintenance activities and operations disruption avoidance have been observed, supporting business cases for system improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace" title="aerospace">aerospace</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20lifecycle" title=" software lifecycle"> software lifecycle</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%20maturity" title=" software maturity"> software maturity</a> </p> <a href="https://publications.waset.org/abstracts/62835/operational-software-maturity-an-aerospace-industry-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62835.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">326</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">6168</span> Application of IED to Condition Based Maintenance of Medium Voltage GCB/VCB</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming-Ta%20Yang">Ming-Ta Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyh-Cherng%20Gu"> Jyh-Cherng Gu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Wei%20Huang"> Chun-Wei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Lung%20Guan"> Jin-Lung Guan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Time base maintenance (TBM) is conventionally applied by the power utilities to maintain circuit breakers (CBs), transformers, bus bars and cables, which may result in under maintenance or over maintenance. As information and communication technology (ICT) industry develops, the maintenance policies of many power utilities have gradually changed from TBM to condition base maintenance (CBM) to improve system operating efficiency, operation cost and power supply reliability. This paper discusses the feasibility of using intelligent electronic devices (IEDs) to construct a CB CBM management platform. CBs in power substations can be monitored using IEDs with additional logic configuration and wire connections. The CB monitoring data can be sent through intranet to a control center and be analyzed and integrated by the Elipse Power Studio software. Finally, a human-machine interface (HMI) of supervisory control and data acquisition (SCADA) system can be designed to construct a CBM management platform to provide maintenance decision information for the maintenance personnel, management personnel and CB manufacturers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circuit%20breaker" title="circuit breaker">circuit breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=condition%20base%20maintenance" title=" condition base maintenance"> condition base maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20electronic%20device" title=" intelligent electronic device"> intelligent electronic device</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20base%20maintenance" title=" time base maintenance"> time base maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=SCADA" title=" SCADA"> SCADA</a> </p> <a href="https://publications.waset.org/abstracts/12921/application-of-ied-to-condition-based-maintenance-of-medium-voltage-gcbvcb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12921.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">329</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">6167</span> Roadway Maintenance Management System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chika%20Catherine%20Ayogu">Chika Catherine Ayogu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rehabilitation plays an important and integral part in the life of roadway rehabilitation management system. It is a systematic method for inspection and rating the roadway condition in a given area. The system performs a cost effective analysis of various maintenance and rehabilitation strategies. Finally the system prioritize and recommend roadway rehabilitation and maintenance to maximize results within a given budget amount. During execution of maintenance activity, the system also tracks labour, materials, equipment and cost for activities performed. The system implements physical assessment field inspection and rating of each street segment which is then entered into a database. The information is analyzed using a software, and provide recommendations and project future conditions. The roadway management system provides a deterioration curve for each segment based on input then assigns the most cost-effective maintenance strategy based on conditions, surface type and functional classification, and available budget. This paper investigates the roadway management system and its capabilities to assist in applying the right treatment to the right roadway at the right time so that expected service life of the roadway is extended as long as possible with acceptable cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effectiveness" title="effectiveness">effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=roadway" title=" roadway"> roadway</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20system" title=" software system"> software system</a> </p> <a href="https://publications.waset.org/abstracts/120967/roadway-maintenance-management-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120967.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">150</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">6166</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.

However, due to the considerable time difference between aircraft and software life cycles, obsolescence has turned into a major challenge for industry in last decades. This paper aims to provide a view on the different causes of software obsolescence within aerospace industry, as well as a perception on the importance of each of them. The key research question addressed is what drives software obsolescence in the aerospace industry, managing large software application portfolios. This question has been addressed by conducting firstly an in depth review of current literature and secondly by arranging an industry workshop with professionals from aerospace and consulting companies. The result is a set of drivers of software obsolescence, distributed among three different environments and several domains. By incorporating monitoring methodologies to assess those software obsolescence drivers, benefits in maintenance efforts and operations disruption avoidance are expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace%20industry" title="aerospace industry">aerospace industry</a>, <a href="https://publications.waset.org/abstracts/search?q=obsolescence%20drivers" title=" obsolescence drivers"> obsolescence drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20lifecycle" title=" software lifecycle"> software lifecycle</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20obsolescence" title=" software obsolescence"> software obsolescence</a> </p> <a href="https://publications.waset.org/abstracts/72049/software-obsolescence-drivers-in-aerospace-an-industry-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72049.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">411</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">6162</span> Appraisal of Maintenance Practices in Selected Tourist Attraction in Bauchi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eldah%20Ephraim%20Buba">Eldah Ephraim Buba</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Bata%20Zoaka"> Amina Bata Zoaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Aishatu%20Ibrahim"> Aishatu Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study appraised maintenance 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">301</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">6161</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">6160</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.

Refactoring is regarded as an effective way to address this problem. Many refactoring approaches at the method and class level have been proposed. But the extent of research on software refactoring at the package level is less. This work presents a novel approach to refactor the package structures of object oriented software using genetic algorithm based community detection. It uses software networks to represent classes and their dependencies. It uses a constrained community detection algorithm to obtain the optimized community structures in software networks, which also correspond to the optimized package structures. It finally provides a list of classes as refactoring candidates by comparing the optimized package structures with the real package structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20detection" title="community detection">community detection</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20network" title=" complex network"> complex network</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=package" title=" package"> package</a>, <a href="https://publications.waset.org/abstracts/search?q=refactoring" title=" refactoring"> refactoring</a> </p> <a href="https://publications.waset.org/abstracts/31191/refactoring-object-oriented-software-through-community-detection-using-evolutionary-computation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31191.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">418</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">6158</span> Providing a Practical Model to Reduce Maintenance Costs: A Case Study in GeG Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iman%20Atighi">Iman Atighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Soleimannejad"> Jalal Soleimannejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Pourjafarabadi"> Reza Pourjafarabadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Moradpour"> Saeid Moradpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the past, we could increase profit by increasing product prices.

A significant percentage of production costs are the maintenance costs, and analysis of these costs could achieve more profit. Most maintenance strategies such as RCM (Reliability-Center-Maintenance), TPM (Total Productivity Maintenance), PM (Preventive Maintenance) and etc., are trying to reduce maintenance costs. In this paper, decreasing the maintenance costs of Concentration Plant of Golgohar Iron Ore Mining & Industrial Company (GeG) was examined by using of MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair) analyses.

The possible allocation of all deferred maintenance tasks to a set of all deferred maintenance tasks to a set of suitable airport resources have termed as alternative and is discussed in this paper from the data’s collected from the kingfisher airlines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20system" title="decision support system">decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=aircraft%20maintenance%20planning" title=" aircraft maintenance planning"> aircraft maintenance planning</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance-cost" title=" maintenance-cost"> maintenance-cost</a>, <a href="https://publications.waset.org/abstracts/search?q=RUL%28remaining%20useful%20life%29" title=" RUL(remaining useful life)"> RUL(remaining useful life)</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics" title=" logistics"> logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/26299/aircraft-line-maintenance-equipped-with-decision-support-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26299.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">503</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">6156</span> Providing a Practical Model to Reduce Maintenance Costs: A Case Study in Golgohar Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iman%20Atighi">Iman Atighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Soleimannejad"> Jalal Soleimannejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Akbarinasab"> Ahmad Akbarinasab</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Moradpour"> Saeid Moradpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the past, we could increase profit by increasing product prices. But in the new decade, a competitive market does not let us to increase profit with increase prices. Therefore, the only way to increase profit will be reduce costs. A significant percentage of production costs are the maintenance costs, and analysis of these costs could achieve more profit. Most maintenance strategies such as RCM (Reliability-Center-Maintenance), TPM (Total Productivity Maintenance), PM (Preventive Maintenance) etc., are trying to reduce maintenance costs. In this paper, decreasing the maintenance costs of Concentration Plant of Golgohar Company (GEG) was examined by using of MTBF (Mean Time between Failures) and MTTR (Mean Time to Repair) analyses. 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">6155</span> Object-Oriented Program Comprehension by Identification of Software Components and Their Connexions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhak-Djamel%20Seriai">Abdelhak-Djamel Seriai</a>, <a href="https://publications.waset.org/abstracts/search?q=Selim%20Kebir"> Selim Kebir</a>, <a href="https://publications.waset.org/abstracts/search?q=Allaoua%20Chaoui"> Allaoua Chaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the last decades, object oriented program- ming has been massively used to build large-scale systems. However, evolution and maintenance of such systems become a laborious task because of the lack of object oriented programming to offer a precise view of the functional building blocks of the system. This lack is caused by the fine granularity of classes and objects. In this paper, we use a post object-oriented technology namely software components, to propose an approach based on the identification of the functional building blocks of an object oriented system by analyzing its source code. These functional blocks are specified as software components and the result is a multi-layer component based software architecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20comprehension" title="software comprehension">software comprehension</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20component" title=" software component"> software component</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20oriented" title=" object oriented"> object oriented</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20architecture" title=" software architecture"> software architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20engineering" title=" reverse engineering"> reverse engineering</a> </p> <a href="https://publications.waset.org/abstracts/32119/object-oriented-program-comprehension-by-identification-of-software-components-and-their-connexions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32119.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">412</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">6154</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.

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">6152</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">6151</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">6150</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.

This choice must be guided by several numbers of decision criteria or objectives related to their production or service activities but also to their level of development and their investment prospects. 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">333</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">6148</span> Productivity Improvement of Faffa Food Share Company Using a Computerized Maintenance Management System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gadisa%20Alemayehu">Gadisa Alemayehu</a>, <a href="https://publications.waset.org/abstracts/search?q=Muralidhar%20Avvari"> Muralidhar Avvari</a>, <a href="https://publications.waset.org/abstracts/search?q=Atkilt%20Mulu%20G."> Atkilt Mulu G.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 1962 EC, the Faffa Food Share Company has been producing and supplying flour (famix) and value-added flour (baby food) in Ethiopia. It meets nearly all of the country's total flour demand, both for relief and commercial markets. However, it is incompetent in the international market due to a poor maintenance management system. The results of recorded documents and stopwatches revealed that frequent failure machines, as well as a poor maintenance management system, cause increased production downtimes, resulting in a 29.19 percent decrease in production from the planned production. As a result, the current study's goal is to recommend newly developed software for use in and as a Computerized Maintenance Management System (CMMS). As a result, the system increases machine reliability and decreases the frequency of equipment failure, reducing breakdown time and maintenance costs. The company's overall manufacturing performance improved by 4.45 percent, particularly after the implementation of the CMMS. <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=manufacturing%20performance" title=" manufacturing performance"> manufacturing performance</a>, <a href="https://publications.waset.org/abstracts/search?q=delivery" title=" delivery"> delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=availability" title=" availability"> availability</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=Faffa%20Food%20Share%20Company" title=" Faffa Food Share Company"> Faffa Food Share Company</a> </p> <a href="https://publications.waset.org/abstracts/151418/productivity-improvement-of-faffa-food-share-company-using-a-computerized-maintenance-management-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151418.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">137</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">6147</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.

Optimal pavement maintenance & rehabilitation strategy is to maximize the pavement condition index of the road section in a network with minimum maintenance and rehabilitation cost during the planning period. In this paper, NSGA-II is applied to perform maintenance optimization; this maintenance approach was expected to preserve and improve the existing condition of the highway network in a cost-effective way. The proposed PMMS is applied to a network that assessed pavement based on the pavement condition index (PCI). The minimum and maximum maintenance cost for a planning period of 20 years obtained from the non-dominated solution was found to be 5.190x10¹⁰ ₹ and 4.81x10¹⁰ ₹, respectively. <p
