The algorithms were tested using a transmission grid transposed in MATLAB. In a first stage it was established a fault location base line, where the algorithms mentioned above estimate the fault locations using the exact line parameters. After that, the positive and zero sequence resistance and reactance of the line were calculated again for different ground resistivity values and then the fault locations were estimated again in order to compare the results with the base line results. The results show that the algorithm which uses the zero sequence impedance of the line is the most sensitive to the line parameters modifications.

At the initial stages of the project, a decision was made that one of its foundations should be the concept of lean management. Because of that, eliminating as many errors as possible in the first phases of its functioning was emphasized. During the start-up of the line, there were identified and documented all production losses (from serious machine failures, through any unplanned downtime, to micro-stops and quality defects). During 6 weeks (line start-up period), all errors resulting from problems in various areas were analyzed. These areas were, among the others, production, logistics, quality, and organization. The aim of the work was to analyze the occurrence of production failures during the initial phase of starting up the line and to propose a method for determining their critical level during its full functionality. There was examined the repeatability of the production losses in various areas and at different levels at such an early stage of implementation, by using the methods of statistical process control. Based on the Pareto analysis, there were identified the weakest points in order to focus improvement actions on them. The next step was to examine the effectiveness of the actions undertaken to reduce the level of recorded losses. Based on the obtained results, there was proposed a method for determining the critical failures level in the studied areas. The developed coefficient can be used as an alarm in case of imbalance of the production, which is caused by the increased failures level in production and production support processes in the period of the standardized functioning of the line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20failures" title="production failures">production failures</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20production%20losses" title=" level of production losses"> level of production losses</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20production%20line%20implementation" title=" new production line implementation"> new production line implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=assembly%20line" title=" assembly line"> assembly line</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20process%20control" title=" statistical process control"> statistical process control</a> </p> <a href="https://publications.waset.org/abstracts/107512/analysis-of-the-level-of-production-failures-by-implementing-new-assembly-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107512.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">128</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">7837</span> Improvement of the Reliability and the Availability of a Production System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakhoua%20Najeh">Lakhoua Najeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims of the work: The aim of this paper is to improve the reliability and the availability of a Packer production line of cigarettes based on two methods: The SADT method (Structured Analysis Design Technique) and the FMECA approach (Failure Mode Effects and Critically Analysis). The first method enables us to describe the functionality of the Packer production line of cigarettes and the second method enables us to establish an FMECA analysis. Methods: The methodology adopted in order to contribute to the improvement of the reliability and the availability of a Packer production line of cigarettes has been proposed in this paper, and it is based on the use of Structured Analysis Design Technique (SADT) and Failure mode, effects, and criticality analysis (FMECA) methods. This methodology consists of using a diagnosis of the existing of all of the equipment of a production line of a factory in order to determine the most critical machine. In fact, we use, on the one hand, a functional analysis based on the SADT method of the production line and on the other hand, a diagnosis and classification of mechanical and electrical failures of the line production by their criticality analysis based on the FMECA approach. Results: Based on the methodology adopted in this paper, the results are the creation and the launch of a preventive maintenance plan. They contain the different elements of a Packer production line of cigarettes; the list of the intervention preventive activities and their period of realization. Conclusion: The diagnosis of the existing state helped us to found that the machine of cigarettes used in the Packer production line of cigarettes is the most critical machine in the factory. Then this enables us in the one hand, to describe the functionality of the production line of cigarettes by SADT method and on the other hand, to study the FMECA machine in order to improve the availability and the performance of this machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20system" title="production system">production system</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=SADT%20method" title=" SADT method"> SADT method</a>, <a href="https://publications.waset.org/abstracts/search?q=FMECA%20method" title=" FMECA method"> FMECA method</a> </p> <a href="https://publications.waset.org/abstracts/95046/improvement-of-the-reliability-and-the-availability-of-a-production-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95046.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">142</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">7836</span> Novel Technique for calculating Surface Potential Gradient of Overhead Line Conductors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sudip%20Sudhir%20Godbole">Sudip Sudhir Godbole</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In transmission line surface potential gradient is a critical design parameter for planning overhead line, as it determines the level of corona loss (CL), radio interference (RI) and audible noise (AN).With increase of transmission line voltage level bulk power transfer is possible, using bundle conductor configuration used, it is more complex to find accurate surface stress in bundle configuration. The majority of existing models for surface gradient calculations are based on analytical methods which restrict their application in simulating complex surface geometry. This paper proposes a novel technique which utilizes both analytical and numerical procedure to predict the surface gradient. One of 400 kV transmission line configurations has been selected as an example to compare the results for different methods.

This is due to the complications of a strain power system. With the snowballing of power demand by the consumers and also the restricted amount of power sources, therefore, the system has to perform at its maximum proficiency. Consequently, the noteworthy to discover the maximum ability boundary prior to voltage collapse should be undertaken. A preliminary warning can be perceived to evade the interruption of power system’s capacity. The effectiveness of line voltage stability indices (LVSI) is differentiated in this paper. The main purpose of the indices is used to predict the proximity of voltage instability of the electric power system. On the other hand, the indices are also able to decide the weakest load buses which are close to voltage collapse in the power system. The line stability indices are assessed using the IEEE 14 bus test system to validate its practicability. Results demonstrated that the implemented indices are practically relevant in predicting the manifestation of voltage collapse in the system. Therefore, essential actions can be taken to dodge the incident from arising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20line" title="critical line">critical line</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20outage" title=" line outage"> line outage</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20voltage%20stability%20indices%20%28LVSI%29" title=" line voltage stability indices (LVSI)"> line voltage stability indices (LVSI)</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20loadability" title=" maximum loadability"> maximum loadability</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20collapse" title=" voltage collapse"> voltage collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20instability" title=" voltage instability"> voltage instability</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20stability%20analysis" title=" voltage stability analysis"> voltage stability analysis</a> </p> <a href="https://publications.waset.org/abstracts/15431/comparative-study-of-line-voltage-stability-indices-for-voltage-collapse-forecasting-in-power-transmission-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15431.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">359</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">7834</span> The Investigation on Pre-Service Teachers' Critical Thinking Dispositions in Terms of Several Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C%C3%BCneyit%20Akar">Cüneyit Akar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Ba%C5%9Faran"> Mustafa Başaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ufuk%20Ulu%C3%A7%C4%B1nar"> Ufuk Uluçınar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research is to examine the critical thinking dispositions of pre-service teachers in terms of several variables. In the line of this aim, we have investigated what their levels of critical thinking dispositions and whether there is any significant different in their critical thinking dispositions. Also, we have examined the relations between their critical thinking dispositions and their parents’ education statues, the number of their siblings, family income levels, and their religiosity level. 202 pre-service teachers who are studying at different departments at faculty of education at Uşak University participated in this research. In study, critical thinking dispositions scale by one of researchers was utilized and its validity and reliability was performed. The findings indicate that the level of their critical thinking dispositions was found to be .376 (arithmetic mean). On the other hand, we found that there is no significant difference in terms of their gender and the department at which they are studying. Furthermore, although there aren’t significant relationships between critical thinking dispositions and their mother education statues, their income levels, their religiosity levels and the number of their siblings; there is any significant positively at low level the relation between thinking dispositions and father educational statues.

This study examines the drained and undrained triaxial tests for large strains on loose to dense, uniformly graded, Leighton Buzzard Fraction A sand. The triaxial tests are conducted under controlled test conditions. The comparison of soil behavior on shear strength characteristics at different effective stresses has been studied at the medium to large strains levels and the uniqueness of the critical state was discussed. The test results showed that there were two steady/critical state lines for drained and undrained conditions at confining pressures less than 1000 kPa. A critical state friction angle is not constant and the overall scatter in the steady/critical state line for the tested sand is ±0.01 in terms of void ratio at stress levels less than 1000 kPa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20state" title="critical state">critical state</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20strain%20behavior" title=" stress strain behavior"> stress strain behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=fabric%2Fstructure" title=" fabric/structure"> fabric/structure</a>, <a href="https://publications.waset.org/abstracts/search?q=triaxial%20tests" title=" triaxial tests"> triaxial tests</a> </p> <a href="https://publications.waset.org/abstracts/77568/evaluation-of-critical-state-behavior-of-granular-soil-in-confined-compression-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77568.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">7832</span> Analysis and Improvement of Efficiency for Food Processing Assembly Lines</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> Several factors affect productivity of Food Processing Assembly Lines (FPAL). Engineers and line managers usually do not recognize some of these factors and underutilize their production/assembly lines. In this paper, a special food processing assembly line is studied in detail, and procedures are presented to illustrate how productivity and efficiency of such lines can be increased. The assembly line considered produces ten different types of freshly prepared salads on the same line, which is called mixed model assembly line. Problems causing delays and inefficiencies on the line are identified. Line balancing and related tools are used to increase line efficiency and minimize balance delays. The procedure and the approach utilized in this paper can be useful for the operation managers and industrial engineers dealing with similar assembly lines in food processing industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20lines" title="assembly lines">assembly lines</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20balancing" title=" line balancing"> line balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20efficiency" title=" production efficiency"> production efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=bottleneck" title=" bottleneck"> bottleneck</a> </p> <a href="https://publications.waset.org/abstracts/68271/analysis-and-improvement-of-efficiency-for-food-processing-assembly-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68271.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">388</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">7831</span> Solution to Riemann Hypothesis Critical Strip Zone Using Non-Linear Complex Variable Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manojkumar%20Sabanayagam">Manojkumar Sabanayagam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Riemann hypothesis is an unsolved millennium problem and the search for a solution to the Riemann hypothesis is to study the pattern of prime number distribution. The scope of this paper is to identify the solution for the critical strip and the critical line axis, which has the non-trivial zero solutions using complex plane functions. The Riemann graphical plot is constructed using a linear complex variable function (X+iY) and is applicable only when X>1. But the investigation shows that complex variable behavior has two zones. The first zone is the transformation zone, where the definition of the complex plane should be a non-linear variable which is the critical strip zone in the graph (X=0 to 1). The second zone is the transformed zone (X>1) defined using linear variables conventionally. This paper deals with the Non-linear function in the transformation zone derived using cosine and sinusoidal time lag w.r.t imaginary number ‘i’. The alternate complex variable (Cosθ+i Sinθ) is used to understand the variables in the critical strip zone. It is concluded that the non-trivial zeros present in the Real part 0.5 are because the linear function is not the correct approach in the critical strip. This paper provides the solution to Reimann's hypothesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reimann%20hypothesis" title="Reimann hypothesis">Reimann hypothesis</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20strip" title=" critical strip"> critical strip</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20plane" title=" complex plane"> complex plane</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation%20zone" title=" transformation zone"> transformation zone</a> </p> <a href="https://publications.waset.org/abstracts/137947/solution-to-riemann-hypothesis-critical-strip-zone-using-non-linear-complex-variable-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137947.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">208</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">7830</span> An Assembly Line Designing Study for a Refrigeration Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20Gundogar">Emin Gundogar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Erkayman"> Burak Erkayman</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysegul%20Yilmaz"> Aysegul Yilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Sazak"> Nusret Sazak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When considering current competition conditions on the world, satisfying customer demands on time has become an important factor that enables the firms take a step further.

The result of X-ray diffraction (XRD) analysis conforms to the formation of an orthorhombic phase of superconductivity in our samples. This is an important finding and indicates that the samples may exhibit superconductivity properties at certain conditions. Our results unequivocally point to a different structural order or disorder in SM/Y samples as compared to Sm based samples. We suggest that different site preferences of oxygen vacancies, predominantly created in CuO2 planes (CuO chains) of Y and Sm-based samples, might be responsible for the observed difference in the behavior. This contention is supported by a host of other considerations and experimental observations. The study investigated the effects of Sm doping on the YBCO system on various properties such as structural, critical temperature (Tc), scanning electron microscope (SEM), irresistibility line(IL), critical current density, jc, and flux line pinning force. It Seems the sample x=0.05 undergoes an insulator transition, which suppresses its superconducting transition temperature (Tc). Additionally, magnetization was measured as a function of temperature (M-T) and magnetic loops (M-H) at constant temperatures of 10. 20, 30, 40, 50 and 60K up to 10KG. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-Tc%20superconductors" title="high-Tc superconductors">high-Tc superconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=Scanning%20electron%20microscopy" title=" Scanning electron microscopy"> Scanning electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20scattering" title=" X-ray scattering"> X-ray scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=Irreversibility%20line" title=" Irreversibility line"> Irreversibility line</a> </p> <a href="https://publications.waset.org/abstracts/189384/dependence-of-the-structural-electrical-and-magnetic-properties-of-yba2cu3o7d-bulk-superconductor-on-the-sm-doping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189384.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">15</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">7828</span> Framework Study on Single Assembly Line to Improve Productivity with Six Sigma and Line Balancing Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inaki%20Maulida%20Hakim">Inaki Maulida Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Yuri%20M.%20Zagloel"> T.

This study presents a discussion on teachers' resistance to critical pedagogy and previous practical frameworks for assessing critical thinking in formative assessment in the classroom through a critical review of the related literature. The authors found out that the main issue of teachers' resistance is not whether teachers should possess theoretical knowledge of critical thinking but how they apply that knowledge in their classroom teaching. In addition, critical thinking in formative assessment may provide teachers with a comprehensive understanding of critical pedagogical planning, implementing, and reflecting. Therefore, this paper intends to discuss a practical step-by-step framework for critical thinking formative assessment to address this resistance. Such discussion is based on a thorough examination of the related theories and frameworks. This review paper will benefit teachers in understanding and reducing their resistance to critical pedagogy as well as in implementing critical pedagogy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title="critical thinking">critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking%20formative%20assessment%20framework" title=" critical thinking formative assessment framework"> critical thinking formative assessment framework</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%20resistance" title=" teachers resistance"> teachers resistance</a> </p> <a href="https://publications.waset.org/abstracts/155786/a-review-of-critical-thinking-formative-assessment-framework-coping-with-teachers-resistance-to-critical-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155786.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">119</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">7820</span> Application of Computer Aided Engineering Tools in Performance Prediction and Fault Detection of Mechanical Equipment of Mining Process Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Jahani">K.

In order to have efficient predictive maintenance, knowing the performance of critical equipment of production line such as pumps and hydro-cyclones under variable operating parameters, selecting best indicators of this equipment health situations, best locations for instrumentation, and also measuring of these indicators are very important. In this paper, computer aided engineering (CAE) tools are implemented to study some important elements of copper process line, namely slurry pumps and cyclone to predict the performance of these components under different working conditions. These modeling and simulations can be used in predicting, for example, the damage tolerance of the main shaft of the slurry pump or wear rate and location of cyclone wall or pump case and impeller. Also, the simulations can suggest best-measuring parameters, measuring intervals, and their locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20aided%20engineering" title="computer aided engineering">computer aided engineering</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=fault%20detection" title=" fault detection"> fault detection</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20process%20line" title=" mining process line"> mining process line</a>, <a href="https://publications.waset.org/abstracts/search?q=slurry%20pump" title=" slurry pump"> slurry pump</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocyclone" title=" hydrocyclone"> hydrocyclone</a> </p> <a href="https://publications.waset.org/abstracts/49774/application-of-computer-aided-engineering-tools-in-performance-prediction-and-fault-detection-of-mechanical-equipment-of-mining-process-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49774.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">403</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">7819</span> Flexible Mixed Model Assembly Line Design: A Strategy to Respond for Demand Uncertainty at Automotive Part Manufacturer in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Yuri">T.

This paper examines the balancing effect of a whole production line of a real auto glass manufacturer in three steps. In the first step, processing time of each activity in the workstations is generated according to a practical approach. In the second step, the whole production process is simulated and the bottleneck stations have been identified, and finally in the third step, several improvement scenarios are generated to optimize the system throughput, and the best one is proposed. The main contribution of the current research is the proposed framework which combines two famous approaches including Assembly Line Balancing and Optimization via Simulation technique (OvS). The results show that the proposed framework could be applied in practical environments, easily. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line%20balancing%20problem" title="assembly line balancing problem">assembly line balancing problem</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20via%20simulation" title=" optimization via simulation"> optimization via simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/24107/a-new-ovs-approach-in-assembly-line-balancing-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24107.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">526</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">7817</span> Metric Dimension on Line Graph of Honeycomb Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Hussain">M.

The customization level of a product is defined by the fraction of aesthetic attributes of the product that the manufacturer chooses to customize. In contrast to the existing literature on product line design that predominantly assumes deterministic demand, we consider the presence of demand uncertainty and frame the product line design problem in a single period (news vendor) setting. We examine the effect of demand uncertainty on product line decisions. Furthermore, we also examine how product line decisions are influenced by channel structure. While we use the centralized channel as a benchmark, we consider the decentralized dual channel where the customized product is sold through an online channel owned by the manufacturer and the standard product is sold through a retailer. We introduce a supply contract between the manufacturer and the retailer for improving channel efficiency and coordinate the distribution channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20line%20design" title="product line design">product line design</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20uncertainty" title=" demand uncertainty"> demand uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=customization%20level" title=" customization level"> customization level</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20channel" title=" distribution channel"> distribution channel</a> </p> <a href="https://publications.waset.org/abstracts/83258/product-line-design-with-customization-in-the-presence-of-demand-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83258.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">186</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">7815</span> Transforming Butterworth Low Pass Filter into Microstrip Line Form at LC-Band Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liew%20Hui%20Fang">Liew Hui Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Idris%20Syed%20Hassan"> Syed Idris Syed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Fareq%20Abd.%20Malek"> Mohd Fareq Abd.

In terms of monitoring and diagnosis, it is quite critical and important to detect some incipient abnormal events of manufacturing processes in order to improve safety and reliability of operations involved and to reduce related losses. In this work a new multivariate statistical online diagnostic method is presented using a case study. For building some reference models an empirical discriminant model is constructed based on various past operation runs. When a fault is detected on-line, an on-line diagnostic module is initiated. Finally, the status of the current operating conditions is compared with the reference model to make a diagnostic decision. The performance of the presented framework is evaluated using a dataset from complex industrial processes. It has been shown that the proposed diagnostic method outperforms other techniques especially in terms of incipient detection of any faults occurred. <p class="card-text"><strong>Keywords:</strong> <a
