Abstract: During the continuous production process, the machines and their components will degrade after several cycles of operations. So there is a need to evaluate these systems for their availability with respect to time to predict their multistage degradation process. The solution procedures for the evaluation of availability of modern complex systems adopted earlier in the literature are very complicated and mathematical cumbersome. Simulation approach for availability analysis of systems has been considered in the literature to get realistic solutions. This work is aimed to buildup a new system dynamics simulation for the time dependent availability analysis of a multistage degraded system. In this a three state degraded system with repair is analyzed and validated. It is proved that that this analysis is an substitute method for transient availability analysis.
