供应不确定和需求信息泄露双重风险下零售商多源采购决策研究

The issues for multi-sourcing decisions under supply uncertainty and information leakage are two hot issues in the research area of supply chain management. Based on a two-echelon supply chain, the program systematically researches the retailers' multi-sourcing decisions under supply uncertainty and demand information leakage risks. Firstly, we invertigate the measurement model of supply uncertainty and the measurement method of information leakage in a two-echelon supply chain consists of one supplier, one incumbent retailer and one entrant retailer. Then, we establish the integrated measurement model of supply uncertainty and demand information leakage risks. Secondly, we systematic investigate contracts design with prevent demand information leakage under supply uncertainty by considering supplier with production diseconomic cost, supplier with production economic cost, endogenous supply uncertainty risk, exogenous supply uncertainty risk. Finally, under a two-echelon supply chain consists of two suppliers, one incumbent retailer and entrant retailer, we study the two competing retailers' sourcing game equilibrium under information leakage and no information leakage respectively. Then, we examine the impact of information leakage on retailers' sourcing game equilibrium. The main results are valuable to retailers to make information management and multi-sourcing decisions better.

供应不确定风险下多源采购决策和信息泄露是供应链管理研究领域的两大热点问题。本项目基于二级供应链，系统地研究供应不确定和需求信息泄露双重风险下多源采购决策问题。首先，考虑由一个供应商、一个在位零售商和一个进入零售商组成的二级供应链，研究供应不确定风险度量模型和需求信息泄露度量方法，从而构建供应不确定和需求信息泄露集成度量模型。其次，综合考虑供应商具有规模经济成本结构、规模不经济成本机构、内生供应不确定风险、外生供应不确定风险等因素，系统地研究信息泄露防范契约设计问题。最后，考虑由两个供应商、一个在位零售商和一个进入零售商组成的二级供应链，系统地研究存在需求信息泄露时两竞争零售商的采购博弈均衡、不存在需求信息泄露时两竞争零售商的采购博弈均衡，继而研究需求信息泄露对采购博弈均衡的影响。相关的研究成果有助于零售商更好地进行信息管理和制定多源采购决策。

本项目立足上游供应商和下游零售商组成的两级供应链，考虑供应商不仅存在供应不确定和信息泄露风险，系统地研究了零售商的信息管理和采购策略问题。本项目在具体的研究过程中，进一步考虑上游企业存在资金不足的问题，具体的研究工作可以总结为以下几个方面：具有供应不确定和信息泄漏风险的低碳供应链的碳排放治理；供应不确定性和企业社会责任风险下供应链中的信息泄露与融资决策；供应不确定和非规模经济成本结构下供应链信息管理策略研究；供应商采取成本减少努力时垂直需求信息共享；供应不确定和政府补贴下的绿色贸易融资均衡；供应不确定与信息泄露风险下双重采购决策。相关的研究成果有助于零售商更好地进行信息管理和制定采购决策，有助于供应商制定有效的信息管理与融资决策。
