Optimal Redundent Units and Inspection Interval in Load-Sharing Parallel System

This paper is concerned with a parallel system that sustains a time-independent load and consists of n components with exponential lifetimes. It is assumed that the total load is shared by the functioning components and the failures of components induce higher failure rates in the surviving components according to the relationship between the load and the failure rates. The power rule model among several load-failure rate relationships is considered. Firstly, the reliability function is obtained. Secondly, the optimization problem in this load-sharing parallel system is considered. The optimal redundant units and inspection interval are obtained. Some numerical examples are studied.
