Selecting optimum maintenance strategy by analytic network process with a case study in the mining industry

The main purpose of this paper is to determine suitable maintenance strategy with the aid of analytic network process (ANP) by which, the inner and mutual dependencies between criteria and strategies can be considered. For this purpose, maintenance strategies are assumed as alternatives and reliability, availability, maintainability and cost as criteria. The proposed approach has been examined in a group of equipments of Chadormalu Mining‐Industrial Company. Findings imply that the priorities of maintenance strategies include TPM, CBM, TBM, DOM and EM, and the priorities of criteria include availability, maintainability, reliability and cost, respectively.
