â¢A maintenance model is formulated for a competing-risk system.â¢The analytical results on system availability are derived.â¢The optimal maintenance policy maximizing steady-state availability is obtained.â¢The optimal maintenance policy minimizing long-run average cost rate is derived.
The availability and optimal maintenance policies of a competing-risk system undergoing periodic inspections are studied in this paper. Specifically, a repairable system with a working state and M failure modes is considered. Each failure mode has a random failure time. When the system fails from the ith(i=1,2,â¦,M) failure mode, corresponding corrective repair is performed which takes a random time Yi(i=1,2,â¦,M). Some analytical results on the instantaneous availability and the steady-state availability for the system are derived. The model is then utilized to obtain the optimal inspection interval that maximizes the system steady-state availability or minimizes the average long-run cost rate. A numerical example for Remote Power Feeding System is presented to demonstrate the application of the developed approach.
