Application of dynamic maintenance strategy model based on group information and reliability

Experts in a variety of businesses have always considered choosing the right maintenance strategy to be a critical concern. Over the years, a variety of maintenance strategies have generally been offered; nevertheless, some researchers have taken steps to provide contingency strategies fit for the conditions as well as dynamic ones. The present research also aims to provide a proper maintenance strategy and compare it with other maintenance strategies from the perspective of experts. Therefore, first, the proposed method is fully described, and then, using the SWARA and COPRAS methods, a comparison is made between the proposed maintenance strategy and seven important maintenance strategies such as reliability-centered maintenance, condition-based maintenance, corrective maintenance, preventive maintenance, time-based maintenance, and failure-based maintenance. However, to determine the appropriate criteria, 13 criteria were extracted from the literature review, the important criteria included cost, time, reliability, etc. According to the expert population of this research including 10 maintenance experts in Tehran city and different industries, the ranking was done and finally, it was found that the proposed method had a noticeable superiority over other methods followed by reliability-centered maintenance and preventive maintenance.
