3、剧,并逐渐由 单个企业间的竞争演变为上下游企业构成的供应链之间的竞争,企业不仅要充分 利用自有资源,还必须与上下游企业合作协调,形成战略同盟,才能赢得更多的 市场份额和收益,基于产品信息全过程管理的 VMI 模式正是由供应链管理思想衍 生而来。供应链协调的目的就在于在供应链组织建立有效的信任机制与激励机制, 形成更为合理的供应链结构,以适应复杂多变的市场环境。供应链契约做为协调 供应链各方行为的一种重要的手段,在供应链协调研究中非常普遍,其应用在企 业实践中取得了良好的成效。因此,本文以 VMI 供应链为背景,研究了供应链契 约协调机制,希望有助于供应链协调的实现。 本文在以往文献的基础上,对
4、供应链补货模型进行了分析,建立了一对多供 应链中的定期补货模型。研究分为三个阶段进行,首先讨论了分散决策下供应链 利润的分配情况,随后提出在供应商主导的基础上,由供应商发起供应链合作, 主动对产品价格做出调整,以增加供应链整体利润。在第三个阶段以实现供应链 协调为目的,引入收入共享契约,实现 供应链整体利润最大化,并合理分配增加 的利润,以提高供应链绩效、实现供应链协调。在此基础上,论文对比分析了缺 货与无缺货两种条件下的补货模型与供应链利润分配,并讨论了模型中相关参数 之间的关系及其供应链成员利润的影响。 论文算例采用 MATLAB7.0 进行仿真,研究结果表明,无论在哪种条件下,分 散决策
5、都会导致供应链效率低下。在分散决策下进行合作的供应链中,总利润与 成员利润均高于无合作机制的供应链,但与实行契约协调的供应链相比,合作供 应链总利润较低,且协调供应链的利润可通过契约约定在供应链成员间合理分配。 分析结果表明,该协调机制能够有效地协调 VMI 供应链各成员利润,实现效益最 大化的目的。 关键词: VMI;供应链管理;供应链协调;补货 II 3 Abstract This paper analyzes replenishment model by considing previous research, and constructing a periodic replenishm
6、ent mathematics models,considering a two-echelon supply chain consists of a single supplier and multiple retailers. Upon these, I study the profits under disperse policy decision. Then the vender bring the supply chain cooperation without revenue sharing contract in order to increase the profits. La
7、stly, coordination mechanism was introduced, the revenue sharing contract is introduced to the models in order to improve the supply chains performance and realize coordination out On this basis, this research compares the differences between the models with backorder and without backorder. And then
8、.the correlations of related parameters and the impacts of them on the profit are analyzed. The model was tested by building numerical examples,using the MATLAB7.0 software. The distributed decision-making supply chain is compared to the cooperated decision-making one and the changes of different va
9、riables and the impacts of them on all parties profits are analyzed. The results show that the mechanism can coordinate the profit of VMI supply chain members effectively and achieve the purpose of maximizing system benefit. The results show that no matter what kind of structure, distributed decisio
10、n will lead to low efficience.In cooperated supply chain, all parties profits are higher than that in distributed decision-making ones.But coordinated supply chains can get the highest profits,and these profits can be appropriatly distributed between the members of supply chain under constract.

In order to b
