Abstract: This paper reveals the comparative analysis of performability and maintenance decision matrix (MDM) for a repairable industrial system. Wrapper forming machine, eye rolling machine, lap cutting machine, and eye forming rolling machine are the four subsystems that comprise this system. The modelling and performability analysis among various subsystems has been done using both stochastic Petri nets (SPN) approach and Markov method. The present study used the SPN as an advanced performance modelling tool and validates their results using Markov method. In addition, a MDM has been purposed which indicates the maintenance priority among various subsystems. This matrix facilitates decision making for various maintenance activities. The results of this study can be useful to maintenance management in developing a maintenance plan and procedures that achieve the ultimate goal of economical maintenance and high level of system availability.

Keywords: performability; availability; maintenance decision matrix; Markov method; stochastic Petri nets; SPN.
