【摘要】：随着顾客需求的多样化和产品更新换代的步伐加速,企业之间的竞争已转为供应链之间的竞争.由于供应链上各个成员的利益不同,他们在追求自身的利益时难免会与供应链整体的效益产生冲突.为了长期的生存和发展,参与供应链协调成为企业发展的难以避免的选择.本文在由单个零售商、单个供应商和单一产品组成的供应链环境下,研究了价格持续下降的产品的供应链协调问题,主要内容有： (1)研究需求受价格和服务水平影响的产品的供应链协调问题.假设产品的价格呈下降的等差数列,分别建立分散决策及基于信用支付和利润改善的库存模型,提出了一种基于信用支付和利润改善的供应链协调方法.通过分析,给出了最优订购周期和服务水平的求解方法,并指出了该协调方法有效实现的必要条件.最后给出数值例子,并分析部分参数变化对零售商、供应商和供应链利润的影响. (2)研究价格和需求均为时变的产品的供应链协调问题.假设价格随时间负指数下降和产品的需求率为时间的梯形函数.分别建立了分散决策、集中决策及基于价格折扣和利润共享的库存模型,提出了一种基于价格折扣和利润共享的协调方法.通过分析,给出了分散决策时的最优订购策略及该协调方法实现供应链有效协调时利润共享因子的取值范围.最后给出数值例子,并考察了部分参数对最优订购策略的影响.
[Abstract]:With the diversification of customer demand and the acceleration of product upgrading, competition among enterprises has turned into competition between supply chains. Because of the different interests of the members in the supply chain, they will inevitably conflict with the overall benefit of the supply chain when they pursue their own interests. In order to survive and develop for a long time, participation in supply chain coordination has become an inevitable choice for the development of enterprises. In the supply chain environment composed of single retailer, single supplier and single product, this paper studies the supply chain coordination of products with declining price. The main contents are as follows: Research on supply chain coordination of products whose demand is affected by price and service level. Assuming that the price of the product is in a decreasing sequence, a decentralized decision model and an inventory model based on credit payment and profit improvement are established, and a supply chain coordination method based on credit payment and profit improvement is proposed. Through analysis, the method of solving the optimal ordering cycle and service level is given, and the necessary conditions for the effective realization of the coordination method are pointed out. Finally, numerical examples are given, and the effects of some parameter changes on retailer, supplier and supply chain profit are analyzed. 2) to study the supply chain coordination of products with time-varying price and demand. Assume that the price decreases with time and the demand rate of the product is a trapezoidal function of time. The inventory models based on price discount and profit sharing are established, and a coordination method based on price discount and profit sharing is proposed. Through analysis, the optimal ordering strategy for decentralized decision and the range of profit sharing factor for effective coordination of supply chain by this coordination method are given. Finally, a numerical example is given, and the influence of some parameters on the optimal ordering strategy is investigated.
