A model is constructed of a repairable item inventory system where on-hand stocks are resupplied both by repair and procurement. The basic properties of the model are analyzed.

Zusammenfassung:A model is constructed of a repairable item inventory system where on-hand stocks are resupplied both by repair and procurement. The basic properties of the model are analyzed. A Poisson failure process is assumed, and steady state probabilities are found for operation of the model under and inventory policies. Further, a compound Poisson failure process under an inventory policy is also analyzed. Measures of supply performance, such as expected number of backorders per unit time, are derived for the system under the various policies. (Author)
