We study a supply chain with one supplier and many retailers that face exogenous endcustomer demands. The supplier and the retailers all try to minimize their own inventory-related costs. In contrast to the retailers’ newsvendor type ordering behavior (under which retailers may place orders freely in every period), we propose two scheduled ordering policies: Scheduled Balanced Ordering Policy (SBOP) and Scheduled Synchronized Ordering Policy (SSOP). Under both SBOP and SSOP, retailers are allowed to order freely only in one period of an ordering cycle, and receive ﬁxed shipments in other periods. However, SBOP is diﬀerent from SSOP in that, retailers take turns to order freely under SBOP, while under SSOP, all retailers order freely in the same period. With the average supply chain cost per period as the performance measure, we identify mathematical conditions under which the scheduled ordering policies outperform the newsvendor type ordering. Through a large scale numerical stu...
