摘要
研究了具排名依赖和浪费厌恶零售商的供应链网络均衡问题。利用变分不等式构建了供应市场均衡。借助排名依赖理论建立并证明了零售商的凹期望效用函数,利用变分不等式构建了零售市场的均衡,解析分析表明:零售商的浪费厌恶程度越大,其最优订购量越少;零售商对极端有利(不利)结果的重视程度越高,其最优订购量越大(小)。利用互补理论构建了需求市场的均衡。进而,利用变分不等式构建了整个供应链网络的均衡。数值结果表明:随零售商的浪费厌恶系数增大,需求市场的均衡价格升高,制造商和零售商的均衡利润减小。随零售商对极端有利(不利)结果重视程度增大(减小),需求市场均衡价格降低(升高),制造商和零售商的均衡利润均增大(减小)。
The supply chain network equilibrium problem with rank dependence and waste aversion retailers was studied. The equilibrium of the supply market was built using the variational inequality. The retailers' concave expected utility function with rank dependence utility was established and proved. And the equilibrium of the retail market was built using variational inequality. The analytical analysis showed that: the greater the degree of retailers' waste aversion, the less the retailers' optimal order quantity; the more attention the retailers paid to the extreme advantage (disadvantage) result, the more (less) the retailers' optimal order quantity; the equilibrium of the demand market was built using the complementary theory. And then, the equilibrium of the supply chain network was built using variational inequality. The numerical results showed that: the increase of the retailers' waste aversion parameter caused the increase of the equilibrium pnce of the demand market and the decrease of the equilibrium profit of manufacturers and retailers; the increase of the degree of the retailers paying attention to the extreme advantage (disadvantage) results caused the decrease (increase) of the equilibrium price of the demand market and the increase (ecrease) of the equilibrium profits of the manufacturers and the retailers.
