Optimal Replacement Policy For A Multistate Degenerative System Using Partial Sum Process With Varying Cost Structures

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 the replacement policy T, where ???? is the working age of the system with varying cost structures are dervied. Additionally, optimality conditions is derived to guide the determination of cost-effective replacement strategies.
