零售商强势的供应链VMI模式演化机理研究

针对目前普遍存在的供应链下游零售商较上游供应商强势的现状,探讨供应商管理库存(VMI)模式的演化机理问题。分别建立了传统库存模式与VMI模式下具有强势零售商的供应链模型,得到不同库存策略下零售商和供应商的支付矩阵。在此基础上,借助双种群演化博弈方法,分别从短期和长期角度对参与双方的演化稳定均衡进行分析。揭示了此供应链结构中,使参与双方获得双赢的VMI能否成功实施的潜在演化机理和关键影响因素。研究结果表明,随着销售量的增加,供应商和零售商在短期和长期的均衡策略分别为(不实施VMI,不实施VMI)和(不实施VMI,不实施VMI)与(实施VMI,实施VMI)共存的情况。进一步分析了利润变化、投资成本与惩罚成本对均衡结果的影响。

Evolutionary Mechanism of VMI in Supply Chain with a Powerful Retailer

Targeting at the ubiquity of more bargaining power that upstream retailer has than downstream supplier in a supply chain,evolutionary mechanism of vender managed inventory model is discussed.Under traditional inventory mode and VMI mode,supply chain models with powerful retailer are constructed respectively so as to obtain a payoff matrix of different inventory strategies.On this basis,by using double groups' evolutionary method,evolutionary stable strategies(ESS) are derived and analyzed in short and long ...
