Abstract

The paper presents maintenance analysis of a specific subsystem with two standby units called Butt Thimble Removal Press 1 & Butt Thimble Removal Press II, of an aluminum plant. Since the subsystem reliability contribute to the entire plant performance and functionality, it becomes important to assess the reliability of the subsystems as well. Six years' of data pertaining to failures, repairs and various cost associated with the system are collected for the purpose, and various rates and costs are also estimated from the data. Measures of subsystem effectiveness such as mean time to subsystem failure, availability of the subsystem, busy period analysis, and expected number of visits by the repairman to repair are estimated numerically by using Semi-Markov processes and regenerative point techniques.
