3PL服务提供商参与下的供应链定价及协调策略

基于单个制造商,单个3PL服务提供商和单个零售商组成的三级供应链系统,将第三方物流服务提供商定量的引入到供应链协调中来,并在物流服务价格由制造商和零售商共同分担的条件下,应用博弈论理论对供应链系统的定价、产量和利润进行了分析。联合定价时,运用相同利润总增长率的协调方式,确定了批发价和物流服务价格的大小;对独立决策和联合协调决策两种情形下均衡解的比较,得出协调定价不仅批发价、零售价和物流服务价都降低,而且还提高了供应链系统的整体利润;通过观察企业定价的大小,可以判断企业是否采取合作的态度,从而为决策者提供理论依据。

Pricing and coordination strategies for supply chain based on third-party logistics provider

The system of supply chain includes a manufacturer,a retailer and a third-party logistics provider.the third-party logistics provider was introduced to supply chain quantitatively;the price of logistics service is shared by manufacturer and retailer;pricing,products and profits are analyzed by game theory.In joint pricing,the wholesale price and logistics price are determined by the coordination of crude growth rate of identical profits;through balanced comparison between independent and joint decisions,this paper concludes that joint pricing can reduce wholesale price,retail price and logistics service price,as well as increase the whole profits of the supply system;meanwhile the pricing can indicate whether the enterprises intend to cooperate with others or not which provide theoretical reference for the decision-makers.
