成本信息共享下供应链成员收益的影响因素

针对由两个零售商和一个供应商组成的两级供应链,基于存在Bertrand竞争的两零售商的成本信息共享模型,研究了供应链中的零售商与供应商最优期望收益的影响因素及其灵敏度分析。结果表明:在各种信息共享组合下,各零售商的收益与零售商成本方差成正比例关系,与零售商所售产品的替代系数成反比例关系,与零售商间成本的相关系数成反比例关系;供应商的收益与零售商所售产品的替代系数成反比例关系。当信息共享存在时,供应商的收益与零售商成本方差、零售商间成本的相关系数成正比例关系。

Factors influencing supply chain members'profits with cost information sharing

A two-level supply chain model with one manufacturer upstream and two retailers engaged in Bertrand competition downstream was developed to study the factors influencing supply chain members' optimal expected profits and the sensitivity to cost information sharing. The results show that for all conditions of retailer cost information sharing, the profits of retailers are directly proportional to the cost variance of the retailers and inversely proportional to the substitution coefficient and correlation coefficient of the products. The manufacturer's profit is inversely proportional to the product substitution coefficient. With cost information sharing, the manufacturer's profit is directly proportional to the cost variance of the retailers and the correlation coefficient of the products.
