【Abstract】 This paper makes some beneficial approaches to safety factor optimization and coordination of twostage supply chain based on modeling research. Under order policy of base stock, the paper introduces concept of effective inventory level, which reflects upstream shortage′s influence on downstream inventory, models the inventory of supplier and buyer and makes global optimization of safety factor to reduce supply chain inventory cost.更多还原
