Bivariate Optimal Replacement Policies Under Partial Product Process for Multistate Degenerative Systems with Varying Cost Structures

Abstract

In this study examines a multistate degenerative system with -working states having -distinct rewards and -failure states with -different repair costs and its maintenance difficulty. The long-run average cost of a multistate degenerative system within the bivariate replacement polices  with varying cost is assessed. The optimality exists under the bivariate replacement policies with partial product process demonstrated.
