Abstract: Through analyzing maintenance spare parts of single-stage multiple base state transition process, a model for maintenance spare parts with delayed transshipment is provided, expression of the probabilities of demands fulfillment by inventory point self, by lateral transshipment, and by delayed transshipment are also given. Based on these, the inventory cost model is provided and model algorithm is constructed. The objective is to minimize the sum of inventory holding cost, downtime cost and transshipment cost. A numerical example is presented to demonstrate the correctness of the model and validity of the algorithm.
