【摘要】：供应链的协调可以有效应对需求的不确定性、信息的时变性、资源的稀缺性等重大挑战.因此,研究供应链的协调具有重要的意义.在现实中,某些产品的市场销售量会受到库存与价格的制约,库存量大而价格低的产品容易吸引大量顾客前来购买,反之则很难激发顾客的购买欲望.本文应用价格折扣策略,对需求受到库存与价格影响的产品的供应链的协调问题进行了研究,主要内容包括： (1)研究了基于价格折扣策略的库存与价格影响需求的供应链的协调问题.在假设库存与价格影响产品需求的条件下,分别建立了分散、集中与协调三种决策下的数学模型；对模型进行了理论分析,设计了求解的算法；应用价格折扣策略对系统的利润进行分配,证明了在一定条件下,通过设置适当的价格折扣率,可以使供应链实现有效的协调.通过数值实验说明了模型,同时对一些重要参数作了灵敏度分析. (2)研究了基于价格折扣和利润增长成比例策略的供应链的协调问题.分别建立了分散与协调决策情形下的数学模型,其中考虑了应用价格折扣产生的机会成本；分析了模型最优解的性质,给出了相应的求解算法；设计了价格折扣和利润增长成比例的协调机制,证明了在一定条件下可以实现供应链的协调.用数值实验方法考察了相关参数的变化对最优订购决策的影响.
[Abstract]:The coordination of supply chain can effectively deal with such major challenges as uncertainty of demand, time-varying of information, scarcity of resources and so on. Therefore, it is of great significance to study the coordination of supply chain. In reality, the market sales of some products will be restricted by the inventory and price. The products with large inventory and low price are easy to attract a large number of customers to buy, otherwise, it is difficult to stimulate the desire of customers to buy. In this paper, price discount strategy is used to study the supply chain coordination of products whose demand is affected by inventory and price. The main contents are as follows: (1) the coordination between inventory and supply chain based on price discount strategy is studied. Under the assumption that inventory and price affect product demand, the mathematical models of decentralized, centralized and coordinated decision-making are established, and the theoretical analysis of the model is carried out, and the algorithm for solving the model is designed. The price discount strategy is applied to distribute the profit of the system. It is proved that under certain conditions the supply chain can be coordinated effectively by setting the appropriate discount rate. The model is illustrated by numerical experiments and sensitivity analysis of some important parameters is made. (2) the coordination problem of supply chain based on price discount and profit growth proportional strategy is studied. The mathematical models of decentralized and coordinated decision-making are established, in which the opportunity cost generated by price discount is considered, the properties of the optimal solution of the model are analyzed, and the corresponding algorithm is given. The coordination mechanism of price discount and profit increase is designed, and it is proved that the coordination of supply chain can be realized under certain conditions. The influence of the change of the relevant parameters on the optimal ordering decision is investigated by numerical experiments.
