A DYNAMIC INVENTORY MODEL WITH DELIVERY LAG AND REPAIR,

Abstract

An inventory system is to be operated over a horizon of T periods during which demands for spare parts arise due to part failure. Successive demands are assumed to be independent and identically distributed random variables. The model considers the periodic review of a single part with backlogging of demand. The decision variables are the amount of initial inventory to stock before departure and the amount of new parts to be ordered during the cruise. Ordering costs include fixed plus unit charges, and linear holding and penalty charges are assessed on end of period inventory. The model is put into a dynamic programming framework. Optimal ordering policies and the existence of an optimal initial inventory level are shown. (Author)
