114Proposing a preventive maintenance multi criteria decision making model by multi choice goal programming method Amir Lanjabi Sharahi a lanjabi@in iut ac ir Date of Submission 2013 09 22 Department of Industrial Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Naser Mollaverdi Naserm@cc iut ac irAbstractIn this research is tried to determine the optimal interval for preventive maintenance and repair for a segmentin a system according to considered criteria for decision making and also with considering the constraints thatexist in the real world for this decision In order to determine the optimal interval for maintenance and repairregarding to multiple criteria MCDM methods are used One of the constraints that we encounter with in the real world and is considered in this research is thatdecision maker tends to have acceptable limits so that firstly if an alternative doesn t satisfy decision maker sexpectations this alternative must be eliminated and secondly if an alternative lies within the limits but farfrom the ideal boundary of decision maker the utility of this alternative must be decreased For achievingthis purpose and considering this requirement in the model multiple choice goal programming is used Another constraint that is considered in this research is that in a real situations when encountering with anunplanned failure failure maintenance cost and failure maintenance time are not known clearly and this factmust be considered in a model used for choosing the optimal interval for maintenance and repair In order toconsidering these situations in the second model parameters are assumed to be fuzzy and modified linearassignment method is used to solve the model Some examples are solved for two models in the final section and sensitive analysis for various parameters isinvestigated Keywords Preventive maintenance multi choice goal programming liner Assignment method number of fuzzy failure maintenance cost failure maintenance time
