【摘要】

We study the problem of optimally managing an inventory system with backordering over a discrete finite time horizon where the objective is minimization of expected total discounted costs.The system consists of two locations each stocking the same product. At the beginning of each time period decisions are made about replenishment at each location and about any quantity to transship between the locations before demand is observed. Leveraging the L-natural -convexity of the problem’s cost function, we characterize the optimal replenishment and transshipment policy for this system. More specifically we show the optimal policy can be described by using the switching curves that are monotone in the system state. We also discuss two extensions. In one extension, we establish L-natural -convexity and apply and apply it to characterize the optimal policy for a lost-sales model, which helps simplify the analysis in the existing work. In the other extension, we investigate the optimal policy for a partial transshipment problem where only one location can transship to the other.
