Integrating Optimization Costs of Spare Part Inventory Maintenance Based On Condition Monitoring And Production Planning Farideh Torabi f torabi@in iut ac ir Naser Molaverdi Supervisor naserm@cc iut ac irDepartment of Industrial and systems Engineering Isfahan university of technology Isfahan IranDegree M Sc Language PersianDate AbstractImprove of access is one of the main concerns in the design of manufacturing engineersmanufacturing sector maintenance of the system is One of the most important activities inorder to improve of access to a production system Maintenance is the set of activities thatmaintain or improve the safety performance reliability and availability of a productionsystem production planning and maintenance program should be considered as a singleunit for avoiding of sudden breakdowns and rework in the planning Since the spare partsis required for maintenance activities thereformore Spare parts inventory should beplanned so as to avoid of waste of time for access to them when the replacement andrepair of machinery be taken This study refers to investigate of the combined productionand inventory control of spare parts and maintenance based on condition monitoringstrategies for a component of the manufacturing equipment The objective function isminimize the total cost of operating and Decision variables is determine the total amount ofstorage used and safety stock level in the time horizon and preventive maintenanceThreshold and production for each product in each period Concurrent programming in thisresearch is defined and solved on parallel and multi product multi machineenvironment Expenses in this study include production costs costs of correctivemaintenance and preventive replacement setup costs goods holding costs at the end ofperiod backorder costs at the end of period and spare parts ordering and holding costs The issue presented in this study is a nonlinear integer programming model that Due to thecomplexity of the problem Gams software with COUENNE solver is used for small sized problems and medium and large sized problems has been resolved with a methodbased on genetic algorithm Keywords Preventive Maintenance Production Planning Spare Part ConditionMonitoring Setup Transfer Genetic Algorithm
