供应链管理中的生产和采购策略研究

Make-or-Buy Decision in Supply Chain Management

摘要: 在由单一供应商和单一零售商组成的供应链中讨论零售商单位生产成本以及不完全信息对供应链成员决策的影响，包括供应商批发价格决策以及零售商的生产和采购策略决策。构建了零售商在完全信息和不完全信息两种情形下选择生产和采购两种产品策略时的数学模型，分别对比两种产品策略下的供应链成员收益得出结论。研究发现，当供应商提供的批发价格高于零售商的生产成本时，零售商也会选择以更高的价格向供应商进行采购。同时不完全信息会削弱“低类型零售商”采购的意愿(不完全信息下低类型零售商仅选择生产策略)，提高“高类型零售商”选择采购策略的意愿。

Abstract: This paper discusses the impact of retailer’s production cost and asymmetric information on re-tailer’s make-or-buy decision in a supply chain consisting of a single manufacturer and a single retailer, including supplier’s wholesale price decision. A model for the complete and incomplete information of retailer’s making decision and retailer’s buying decision is constructed, and the conclusion is obtained by comparing the benefits of the supply chain members under the two product strategies. The paper showed that when the wholesale price offered by the supplier is higher than the retailer’s production cost; the retailer will choose to purchase from the supplier at a higher price. At the same time, incomplete information will weaken the willingness of “low-type retailer” to purchase (low-type retailer only selects production strategies under incomplete in-formation) and increase the willingness of “high-type retailer” to purchase products.
