Suppose that a large discount retailer with a lot of purchasing power in a supply chain requires that all suppliers incorporate a new information system that will reduce the cost of placing orders between the retailer and its suppliers as well as between the suppliers and their suppliers. Suppose also that order quantities and lead times are related: the smaller the order quantity the shorter the lead time from suppliers. Assume that all members of the supply chain use a continuous review system and EOQ order quantities. Explain the implications of the new information system for the supply chain in general and the inventory systems of the supply chain members in particular.
