摘要
从动态网络下的鲜活农产品三级供应链出发,考察了供货量损耗比对供应链的影响。构造了含有供货量损耗比的变分不等式模型,并把价格弹性引入到了模型中,从而得到了鲜活农产品供应链的网络均衡模型,针对不同损耗和不同价格弹性的情况进行了分析,探讨损耗比和价格弹性对网络均衡的影响。分析可知,损耗比的增加,以及价格弹性的增加,都会降低整个网络的总利润。因此,要获得最大利润,生产商和销售商应该努力最小化损耗比和价格弹性这2个参数。
The impact of supply loss ratio on the dynamic supply chain networks of fresh agricultural prod- ucts is addressed. By means of the variational inequality with the supply loss ratio and the price resilience in it, a model of supply chain network equilibrium is constructed. Cases of various supply loss ratios and various price resilience are analyzed, by which the impact of supply loss ratio and price resilience on the supply chain network equilibrium are found out. With the increase of supply loss ratio and price resilience, the total profit of all the parties will decrease. It is implied that producers and retailers should minimize the supply loss ratio and price resilience to maximize the total profit.
