考虑易逝品的流通时间增加对供求双方博弈的影响

首先考虑到易逝品在二级供应链的流通过程存在各方利润比例分配不合理的状况，通过建立易逝品流通的利润博弈函数，对利润函数进行分析得出各方利润的最大的均衡条件。再者考虑易逝品的从属失效性，构建关于时间的易逝品损耗函数；将损耗函数与利润博弈函数相结合，分析随流通时间变化对各方在整条供应链上的利润比例的变化。结果表明，流通时间的增加需求方所占的利润比例逐渐向1靠拢；当流通时间接近易逝品的腐烂周期时，供应方所占的利润比例接近于0。

Considering the profit ratio distribution unreasonable condition of perishable goods circulation in the secondary supply chain, through the establishment of the perishable goods circulation profit game function, the profit function was analyzed to draw the biggest profit by the parties equilibrium conditions. Also considering dependent failure of the perishable goods, the perishable goods loss function about time was constructed; Combining loss function and profit game function, profit ratio changes with the circulation time of the parties on the supply chain were analyzed. It was found that circulation time increase the demand of the profit ratio gradually close to 1. When close to the perishable goods circulation time decay cycle, suppliers, the proportion of profits close to 0.
