Purpose The purpose of this paper is to investigate the extent at which reliability of aluminium wire rolling mill can be improved by ameliorating current control and maintenance practices. Design/methodology/approach The paper deals with the discrimination of the most critical components by substantial shop-floor failure data. The research work narrates a method for evaluating maintainability criticality index (MCI) for each failure cause of identified critical components through two different MCDM approaches, one based on grey-complex proportional risk assessment (COPRAS-G) and other based on preference section index (PSI). Findings The primary findings of this research work are to prioritize the maintenance activities by comparing results obtained through different failure analysis models. It is proposing improvements in the maintenance plan of critical components like; bearings, gears, and shafts of aluminium wire rolling mill which are commonly representing the most critical components in a large ran...
