Abstract

For a repairable system consisting of line-replaceable components, its operational availability depends on component reliability, the level of redundancy, and the availability of spare parts. In prior studies, redundancy allocation and spare parts provisioning are treated separately. In this paper, we study a joint decision-making problem, in which the component redundancy level and the spares stock quantity are to be determined in order to maximize the system operational availability under economic constraints. Numerical examples are provided to illustrate the applications and highlight the managerial implications of this integrated redundancy allocation and spare parts logistics methodology.
