Abstract: Maintenance is a routine and recurring process of observing a meticulous system in its customary service condition to deliver its predictable performance without any time delay. It also encompasses restraining the downtime of certain equipment as the catastrophe of a component causes service failure. The reliability of a transportation system can be improved by a better maintenance approach, consequently increasing its availability. The physical need for any system can be described through an upgraded information system. It encompasses the failure history; hours spent on maintenance and operating performance of the vehicle, which are monitored over time. In this work, the fuzzy model has been designed to obtain the fuzzy mean time to failure/repair values. The entire process has been carried out on the basis of expert knowledge for optimisation of safety and reliability assessments. This information can be used to make an in-time decision, prolong the life of the equipment, or amend inclusive vehicle reliability. The overall reliability of the transportation system has been appraised based on the reliability of individual vehicles.

Keywords: fuzzy reliability; MMTF; maintenance mean time failure; MTTR; mean time to repair; recital appraisal; transportation system.
