用灰色理论研究易腐品系统中一对多合作机制

One-to-multiplicity cooperation mechanism in perishable products system using grey theory

研究由"农户+多个公司"模式组成的二级易腐品供应链系统中,在灰色价格下,当多个公司之间存在竞争关系时易腐品供应链系统中合作机制问题.建立农户和多个公司的灰色博弈模型,分析多个公司之间的竞争对公司和农户合作的影响.分析表明:在灰色市场价格下,公司的违约处罚金和农户的奖励补贴的设置是他们合作与否的关键因素;多个公司之间的竞争仅影响公司的违约,农户违约和公司之间竞争无关.最后提出了易腐农产品供应链中双方达到纳什均衡供应链绩效最大化的策略和措施,并通过实例进行了验证.

The cooperation mechanism in a two-stage perishable agricultural products supply chain that consists of a farmer and many companies was studied when many companies were competitive under grey market price. The grey game model of a farmer and many companies is first set up. Then, the influence of many companies competition on the cooperation of a farmer and companies are analyzed. The analysis shows that the penalty for company of default and the bonus given to farmer are the key factors of a farmer and companies cooperation and the many companies competition only affect the default of many companies and it is irrelevant to the default of a farmer. Finally, the optimization equilibrium strategy and measure to maximize both sides profit under grey market price are proposed , and validated it with an example.
