Abstract

The aim of the study is to find how a framework could be developed for selecting the relevant strategy and policy of maintenance by TOPSIS and weighted mean approaches. For this purpose, first maintenance criteria and KPIs have been weighted; and then, maintenance strategy and policy have been selected. Esfahan Steel Company (ESCO) has been selected as the case study where in, the proposed approach has been examined. Statistical population included maintenance experts and managers of the company. TOPSIS and weighted mean approaches have been used for analysis. Findings imply that the strategy of preventive maintenance and policy of proactive maintenance have been selected and suggested to ESCO for decision making with the weights of 144.86 and 162.84, respectively.
