Given that various operational methods can be considered for a system,applying changes to study the results and determine the best operational technique is costly and disrupts the ***,to analyze and evaluate the outcomes of employing different operational methods,simulation is *** this study,to improve the performance of a medical imaging center(MIC),first,this center was simulated and then,different scenarios were defined and ***,using the simulation results and for evaluating the scenarios through Data Envelopment Analysis(DEA),each scenario was considered as a decision making unit(DMU).Since simulation results of each scenario are uncertain and differ for different iterations,a method was utilized capable of using the results of all *** the other hand,indexes such as satisfaction,patient’s appropriate waiting,helpful servicing with the least number nurses and the maximum number services that have fuzzy nature,are important factors for ***,using the simulation results and considering the system manager’s idea,a method was proposed for determining the fuzzy values of these ***,a ranking model and an algorithm were proposed for determining a unique ranking and introducing the best scenario to improve the performance of MIC.
