We study a discrete-time periodic-review inventory system where the unmet demand is backordered. When inventory level is nonnegative, the inventory manager does not(More)
W e study a firm's optimal transshipment problem considering the impacts of setup costs for transshipment and demand distribution shapes. We assume that the demand follows a three-point distribution, which changes from a degenerate distribution, to a unimodal distribution, and to a bimodal distribution as the demand shape parameter increases. We find that(More)
