Redundant Spares Allocation to Reduce Reliability Costs,
Abstract
Due to rapid developments in technology, provision of adequate number of spares at the time of acquisition of equipment has become a significant problem. Increased complexities of modern electronic equipments have resulted in modular designs. In the event of failure of one such a module, it is readily removed and replaced by a new one from the inventory. The problem considered here is the optimal selection of the inventory of spares for a system build from two kinds of modules, the larger of which can be connected so it performs the role of the smaller one. The optimal inventory is the least costly one which achieves a specified probability that the spares will not be exhausted over the design lifetime. For some costs and failure rates it is most economical to use the larger module for both roles because of the resulting increase in flexibility in the deployment of a single type of spare module. The problem has been approached by analytical as well as simulation methods. (Author)
