[Invited Talk] A Note on Generalized Ordering Policy

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we discuss the generalized ordering policy, in which when an ordered spare is delivered after a randomized lead time it is put into the inventory if an original unit is still operating and the original one is replaced/exchanged by the spare in stock when the original one fails/passes a prespecified time, whichever occurs first. We apply the expected cost per unit time in the steady state as a criterion of optimality and obtain the optimal ordering policies which minimize this expected cost. We show that we should consider either the extreme policy that the delivered spare is put into the inventory until the original unit fails, or one that the spare takes over the operation as soon as it is delivered.
