A multi-objective optimization of maintenance policies using weighted comprehensive criterion method (WCCM)

Maintenance is playing a crucial role in keeping and improving availability, performance efficiency, quality products, on-time deliveries, and environment and safety requirements at high levels. Usually decision maker has to consider conflicting criteria such as cost, reliability, safety, risk, and availability when selecting among various maintenance policies. The purpose of this work is to develop a multi-objective optimization model that will be used to compare the performance of maintenance policies (age, block good as new, block bad as old) based on four performance criteria which are cost, availability, life-time and reliability by using weighted comprehensive criterion method to convert all the objectives into a single objective. The results of the model demonstrated that using the suggested model enables the decision maker the select the most cost-effective maintenance policy under different scenarios.
