The cost of maintaining these facilities is a combination of regular maintenance costs and urgent recovery costs. Generally, the urgent costs are much higher than regular costs. Regular maintenance work should result in fewer sudden failures, and thus reduce these urgent costs. However, if the regular maintenance is too frequent, its cost becomes too high. Therefore, it is important to balance the regular and urgent costs to minimize the overall maintenance cost. We propose a maintenance schedule optimization method based on the failure probability distribution of the facilities. The total cost is mathematically modeled, with the regular maintenance schedule included via decision variables and the occurrence of failures modeled as stochastic variables. The stochastic total maintenance costs are evaluated using a Monte Carlo method, and a genetic algorithm is employed to optimize the maintenance schedule. The proposed method is evaluated using data provided by a Japanese railway company, and our results confirm that the method produces an excellent maintenance schedule. A statistical test shows there is a significant difference between the proposed and conventional methods.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124945552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shea butter husk was treated in a polymeric mixture of calcium alginate to produce beads of approximately 1.56 mm ± 0.14 spherical shapes. Optimum parameters evaluated revealed an effective column performance at flow rate of 0.5 ml/min, bed heights of 12 cm and at initial concentrations of 50 mg/L. The percentage removal (%R) of the Pb (II) ions at 0.5 ml/min was 77.31 % with adsorption capacity of 1.888 mg/wet bead. The Thomas and Yoon Nelson model predicted the break through curve to a large extent with the correlation coefficients ranging between 0.8098-0.9676. Their rate constants (KTh and KYN) were higher at lower flow rate, higher bed heights and at lower concentrations. The adsorption capacities of the column at this conditions was 6431.606 and 76, 536.111 mg/g respectively for Thomas and Yoon Nelson model These results revealed that with the enhancement of the shea butter husks, polluted effluents concentrations can be reduced to their threshold values before discharged into the water bodies via a continuous fixed bed column.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130866417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This metamodel is intended to take into account the structural characteristics of the product and its behavior along the life cycle, from the design phase to its end of life. For that, first, we proposed 4 types of X-DSM matrices that are used to represent the components, design parameters, activities and the associated project's stakeholders. And then, we use SysML language diagrams to represent the behavioral views of the product at different stages of its lifecycle. The proposed metamodel complies with the SysML formalism including both the 7 UML4SysML views and 2 additional views aimed to the care of Specifications and Parametric settings. These last two views are key factors for modeling products with multiple configurations. In the second part of the article, we propose implementation architecture to exploit the functionalities of such a metamodel in collaborative design.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131476491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ANN enables, due to its promising inherent capabilities, to predict existence of undesirable effects such as cracks within the structure. Natural frequencies of the structure particularly the first three vibration modes are the most pronounced features of the structure to be evaluated for the health monitoring tasks. Crack in the structure make it weaker and under certain loads it may extend to complete fracture and sometimes to catastrophic failure. In this paper, the ANSYS software which employs finite element (FE) techniques is used to generate data for solid cantilever beams and simply supported beams. Natural frequencies are obtained for the first three vibration modes taking into account that the structure is linear for the healthy and the cracked structures. For different crack locations and crack depths, the ANSYS data on natural frequencies and vibration modes show lower values compared with healthy structure. These are good indicators to be used for training the Artificial Neural Network (ANN) tools. Results of ANSYS software is first verified with some available theoretical solutions and then results of the trained artificial neural network (ANN) for defected structure are compared with ANSYS solutions. The findings of this study suggest high accuracy of ANN on structural health monitoring with robust prediction of size and location of cracks.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131499909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially, pull (Kanban) system, POLCA and kitting were used to replenish components to the assembly line, where appropriate. Pull system and kitting were used in many cases of the automotive sector because of the high material handling costs, space requirements and many product customization requests. Kanban systems were proposed for coordinating the supply of components' with relatively smooth and high demand. For supplying components with low and variable demand, POLCA systems were suggested. Although conventional Kanban systems require replenishment of components by containers, kitting may a better systematic to save space in buffer areas of the assembly lines where products have common components. Therefore, a kitting methodology was also developed in this study, based on clustering of components into the kits. Replenishment of kits of components is coordinated by Kanban. The proposed methodology is applied in an automotive supplier producing air-conditioners. As a result of this application, time spent by the assembly line operators for checking the parts availability was eliminated. Material feeding time was reduced by %80. Time spent by the production planner for controlling the production requirements were reduced by %72.","PeriodicalId":410110,"journal":{"name":"2015 International Conference on Industrial Engineering and Operations Management (IEOM)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124370209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
