第三方物流服务质量约束下具有利他性的网购供应链决策模型

Research on Decision Model of an Online Shopping Supply Chain with Considering Altruism under TPL Service Quality Constraint

针对单个网络商店和单个第三方物流(TPL)形成的服务供需关系,在TPL服务质量约束下构建了一个基于利他属性的网购供应链决策模型,讨论了利他属性对网购供应链系统的影响。首先在分散决策模式下,探讨了系统的均衡解和绩效;然后,分析了集中决策模式下参与者的决策和利益情况,对比分析发现分散决策模式下网络商店和TPL会因利益冲突而使系统决策失衡,从而降低了供应链参与者利润和系统绩效;在此基础上,讨论了在TPL服务质量约束下利他性与系统决策和绩效的关系,结论表明:利他属性的存在有助于改善系统决策和供应链绩效;最后,通过数值分析,进一步揭示了单方参与者具有利他性时的系统决策和绩效的变化规律,以及双方参与者切利他性互动情景下系统决策的变化规律。

For the service supply and demand relationship between an online store and a TPL,a decision model considering the altruism of members in an online shopping supply chain（OSSC） is constructed under the logistics service constraint. The impact of the altruism of members in the OSSC on decisions is analyzed. Firstly,the equilibrium solutions and the performance of the system are discussed in the decentralized decision scenario.Secondly,the decisions and profit of members and the system performance are discussed in the centralized decision scenario. Then,a comparative study about the two decision models revealed a conflict existing between the online store and the TPL. And the benefit conflict leads to making unbalanced decisions,which reduce the benefit of members and the performance of the whole system. Thirdly,the impacts of altruism on the decisions and benefits of all members are explored under the logistics service quality constraint. Finally,a computation example analysis is employed to further discover the law of change of decisions and performance in the two scenarios： one member has altruism attribute and both members have altruism attribute.
