Exploring Fuzzy SAW Method for Maintenance Strategy Selection Problem of Material Handling Equipment

Abstract

This paper proposes and presents a different approach of selection an appropriate maintenance strategy of material handling equipments in Punj Lloyd plant Gwalior (India) using Fuzzy Simple Additive Weighting (FSAW) method. In this paper by the experts weights are assigned in linguistic variables, these linguistic variables are translated into triangular fuzzy numbers (TFN) to the Multi-Criteria Decision-Making (MCDM) problem. Basic six types of maintenance strategy are corrective maintenance, preventive maintenance, condition based maintenance, opportunistic maintenance, predictive maintenance, and breakdown Maintenance and ten maintenance decision criteria namely quality, spare parts inventories, purchasing cost of spare parts, maintenance labour cost, Reliability, safety, Maintenance time, Facilities, cost of supporting equipment, and environment. In this paper breakdown maintenance strategy best one out of all maintenance strategy for material handling equipment in Punj Lloyd plant Gwalior (India).
