Abstract

Reliability Centered Maintenance (RCM) is a widely practiced maintenance and repair activity for decreasing equipment downtime. In this paper we conduct an investigative case study on engine maintenance and repair hub, located in the coal mines of Eastern India, wherein breakdown maintenance was still practice. A thorough research was conducted into the causes of failure of all engines which came to the workshop during a three year period and also the various spare parts used in each type of failure, followed by classification of the various spare parts on the basis of their reliability. With the help of this failure data, reliability analysis of the various engine models was conducted using Reliasoft’s Weibull++ and Mean Time To Failure (MTTF) was calculated. Based on these estimations, we scheduled a maintenance program and implemented it for six months and compared the resulting failure trends to the previous data. The results of the case study clearly show that RCM can lead to cost effective Spare Parts Management.
