Application of the concept of multi-criteria aggregation in the maintenance process

This work is part of the implementation of reliability-based maintenance (RCM) in a gas complex located in Algeria. The objective targeted of the study is to classify the production equipment according to their degree of criticality with respect to certain criteria. To do this, we propose to apply two methods centred on the concept of multi-criteria aggregation and compare the results to obtain a classification of critical equipment. Prioritization of the equipment so obtained will identify priority actions for maintenance.
