【摘要】：将供应链管理引入需求分布自由的市场环境中,以回购契约作为管理的激励机制,研究均为风险中性的供应商—零售商构成的供应链系统的最优订购—定价决策以及回购契约的协调性问题.研究需求分布自由环境下供应链系统的协调性具有重要意义,尤其是对缺乏充分历史销售数据的新产品,短生命周期产品而言.基于期望收益准则和需求分布自由,分别建立供应链系统、零售商和供应商的上界、下界和最小期望收益模型,并在不同的需求依赖价格模式(加型模式和乘型模式)下,分析供应链的最优订购—定价决策以及回购契约的协调性.研究发现,供应链系统的期望收益在由上界向下界乃至退化为最小期望收益时,回购契约的协调能力逐渐增强.即,在上界期望收益模型中,回购契约无法协调供应链系统;在下界期望收益模型中,存在唯一的一组回购契约参数协调供应链系统;在最小期望收益模型中,回购参数是批发价格的反应函数,回购契约可以灵活地协调供应链系统.
[Abstract]:Supply chain management is introduced into the market environment of free distribution of demand, and the repurchase contract is used as the incentive mechanism of management. This paper studies the optimal order-pricing decision and the coordination of repurchase contracts in supply chain systems composed of risk-neutral suppliers and retailers. It is of great significance to study the coordination of supply chain systems in the environment of free demand distribution, especially for new products, short life cycle products, which lack sufficient historical sales data. Based on the expected return criterion and the free distribution of demand, the supply chain system, the upper bound, the lower bound and the minimum expected income model of retailers and suppliers are established, respectively, and under different demand dependent price models (additive model and multiplicative model). This paper analyzes the optimal order-pricing decision and the coordination of repurchase contract in supply chain. It is found that when the expected income of supply chain is reduced from upper bound to minimum expected return, the coordination ability of repurchase contract is gradually enhanced. That is, in the upper bound expected income model, the repurchase contract can not coordinate the supply chain system; in the lower bound expected income model, there is a unique set of repurchase contract parameters to coordinate the supply chain system; in the minimum expected return model, Repurchase parameter is the response function of wholesale price, and repurchase contract can coordinate supply chain system flexibly.
