Abstract
One of the most important management concepts in large and manufacturing industries is the concept of maintenance, which has a significant impact on productivity, optimal performance, and costs due to sudden failures in manufacturing industries. Many maintenance managers believe that using a proactive maintenance policy is more cost-effective than other maintenance policies due to the longer life cycle of the equipment, but there is no reliable evidence to prove this belief in manufacturing businesses. The purpose of this paper is to design a mathematical model to help managers in the decision-making process of choosing the most appropriate maintenance approach from a cost-benefit perspective. In this study, we used the gamma probability distribution to estimate the time required for a failure event to occur in a pump, before and after the failure. In this work, we examined the cost of three different maintenance approaches (corrective, preventive, and predictive) by considering different parameters. It was observed that the corrective approach, due to the lack of a maintenance process, had the shortest life cycle duration and the highest cost, while the predictive approach had the longest life cycle duration and the lowest cost, and the preventive approach was placed between its two counterparts. The mathematical model in this study helps managers in this field to decide on the most appropriate network policy.
Highlights
- A new framework for cost benefit analysis is proposed.
- Gamma process was used to model the destruction process in two cases with and without erosion.
- The goal is to achieve the most optimal maintenance strategy.
