二级物流服务供应链定价及其效率研究

研究了需求不确定条件下,基于利润最大化原则的二级物流服务供应链的定价及效率问题。基于物流服务供应链中集成商市场和供应商市场的四种不同市场组合,建立了以集成商为主导的集成商与供应商之间的Stackelberg博弈模型,求得集成商的最优定价和最优订购量,比较了不同集成商和供应商市场组合下的物流服务供应链的效率高低情况。最后,进行了数值计算,得出集成商的最优定价和最优订购量,验证了不同市场组合下的物流服务供应链效率高低情况。结果表明:集成商的最优定价和最优订购量同时受集成商和供应商所处的市场环境影响;集成商市场寡头垄断、供应商市场完全竞争的情形下物流服务供应链效率最高,集成商市场垄断、供应商市场寡头垄断的情形下物流服务供应链效率最低。

Research on Pricing Decisions and Efficiency in a Two-Level Logistics Service Supply Chain

According to the principle of profit maximization, the pricing and efficiency of two-stage logistics service supply chain are discussed under the conditions of demand uncertainty. Based on four market combinations between vendors and integrators, the integrator-led Stackelberg game model is developed, the optimal pricing and optimal order quantity of integrators are found out, and the efficiency of two-stage logistics service supply with different market combinations are compared. Lastly, numerical example is used to evaluate the optimal pricing and optimal order quantity of integrators. The descending order of the efficiency values with four market combinations is verified. The results show that the optimal pricing and optimal order quantity of integrators are affected by both the market types of vendors and integrators. There is peak efficiency of logisitics service supplly chain when the market of integrators is oligopolistic and the vendors market is a perfect competition one. And the efficiency is lowest when the integrators' market is monopdistic and the market of vendors is digopolistic.
