在强势零售商存在的情况下,研究了联合采购对再制造闭环供应链回收策略的影响。建立了两种采购方式的闭环供应链模型,且对两种采购方式进行了比较分析。研究表明:当回收努力成本较大或较小时,联合采购时的回收比例大于单独采购时的回收比例;当零售商间差异性较大时,弱势零售商倾向于联合采购,且联合采购时供应链的利润大于单独采购时供应链的利润;当联合采购时强势零售商的讨价还价能力较强时,联合采购时两零售商的利润分别大于单独采购时的利润。
This paper studies the problems that the joint procurement affects the remanufacturing closed- loop supply chain recovery strategies with a dominant retailer, and establishes a closed-loop supply chain model of two purchase ways. Furthermore, it compares and analyses the two purchase ways. The study finds that. (1) when the recovery effort cost is smaller or larger, the recovery ratio of joint procurement is greater than the individual purchase; (2) when the diversity between the dominant retailer and the weak retailer is large enough, the weak retailer prefer joint purchase more, and the chain's profit of joint purchase is greater than the chain's profit of single purchase; (3) the two retailers' profits of joint procurement supply are larger than the single procurement when the dominant retailer's bargaining power of joint procurement is strong.
