This paper considers the optimal spare ordering policies for a cold standby redundant system with two dissimilar units. Especially, the salvage cost is discussed and the expedited order lead time is assumed to be arbitrary. We show that, under certain conditions there exists a finite and unique optimum policy which minimizes that cost or maximizes the expected availablity.
