N-policy for redundant machining system with double retrial orbits using soft computing techniques

Abstract

The present study is concerned with the performance prediction of a double-retrial orbit redundant repairable machining system. Both primary and secondary orbits are available as waiting/buffer space for the failed units. In these orbits, the failed units can reside and attempt repairs again. According to the N-policy, if there are no units in the orbits for the repair job, the repairman goes on vacation and resumes the repair job when N-failed units are accumulated.
