Consider a three-firm supply chain consisting of a retailer, manufacturer, and supplier. The retailer's demand over an 8-week period was 110 units each of the first 2 weeks, 220 units each of the second 2 weeks, 290 units each of the third 2 weeks, and 420 units each of the fourth 2 weeks. The following table presents the orders placed by each firm in the supply chain. Notice, as is often the case in supply chains due to economies of scale, that total units are the same in each case, but firms further up the supply chain (away from the retailer) place larger, less frequent, orders.

Orders placed by each firm in the supply chain include:

Week	Retailer	Manufacturer	Supplier
1	110	220	660
2	110
3	220	440
4	220
5	290	580	1,420
6	290
7	420	840
8	420
