Comparative Analysis Between Three Reliability Models of a Two-Unit Complex Industrial System

This paper presents the reliability modelling and analysis of a complex industrial system with two units operating in parallel. To facilitate study, real failure-maintenance data arecollected. Data depicts that unit is repaired upon failure by single repairman. Reliability indices such as mean time between failures, availability, expected number repairs, busy period repairman are estimated using semi-Markov processes regenerative processes. Finally, comparative three models for presented.
