Abstract :

  The purpose of this paper to evaluate the preferred maintenance strategy is multi-criteria decision-making methods. For the purpose of decision making under uncertainty has been studied, So that all data is arranged in a triangular fuzzy number. In the proposed method of this paper, the weights are calculated Then Strategies and then taking measures with the fuzzy TOPSIS method, fuzzy vikor and Fuzzy Simple Additive Weighting rankings were. Then, taking into account the ranking obtained using these methods and techniques Copeland and Average Rating final ranking of strategies was calculated. In order to assess the performance of the model, a case study was carried out at Bid Boland Gas Refinery Co and Results obtained from the use of this method is presented in the target company. The results indicate that the model is an appropriate model for preventive maintenance strategy selecting. Finally, suggestions for future research are presented.
