| 摘 要： | 在具有价格弹性需求的两层供应链系统中,考虑到价格弹性指数的模糊性和供应链延期支付策略,建立了含缺货的制造商-零售商协调模型.运用符号距离反模糊化方法将其转化为确定模型.基于遗传算法,设计了其求解方法,获得了制造商最优信用期和零售商最优零售价.数值结果表明:模糊环境下的延期支付策略降低了产品的市场零售价,同时增加了供应链中各成员的利润,因此实现了供应链协调.进一步分析显示当模糊价格弹性指数的上(下)界变化反映出的不确定性减弱时,制造商提供更长的信用期,且制造商和零售商的利润均增加(减少).

| Abstract: | The intensifying market competition is pressuring buying companies to delay the payment schedule for selling companies.The delayed payment can help the buying company earn buffer time to survive economic downturns.In addition,market demand is related to product price.Companies are facing challenges of coping with price-sensitivity of market demand by using price elasticity indices.Investigating market demand using the fuzzy price elasticity index appears to be a more realistic approach.In the first part,we ... |
