Optimal Replacement Policies for a Multistate Degenerative System using Partial Sum Process

Abstract

This paper investigates the maintenance problem of a multistate degenerative system with k -working states and l -failure states. The long-run average cost for a multistate degenerative system under univariate replacement policy: T-policy, T-policy with NONN repair times are derived. Additionally, optimality conditions are established to guide the determination of cost-effective replacement strategies.
