中文摘要：

制造商的多产品动态定价问题要考虑原材料的采购、多种产品的生产制造、库存,以及处理下游订单等的成本和未满足的需求及运送的前置时间。通过引入时空网络,建立使制造商期望利润最大的动态定价数学模型,实例分析表明,制造商期望利润最大化的最优价格、最优产品生产量与最优库存量能,是制造商制定合理的生产计划的决策依据。

英文摘要：

The paper studies the multi - products dynamic pricing problem based on manufacturer, in which the demand of purchasers is uncertain. Along with the cost of raw - material, production of multi - products, the stock and the cost of executing order from downstream enterprise, the unsatisfied demand and the lead time in delivering are taken into account. The time - space network is introduced when describing this dynamic supply chain network, by which the mathe- matical model for dynamic pricing is set up that can make manufacturers get the biggest profit. The empirical study proves the rationality of this model. The optimal price, output and stock from the numerical example can provide manufacturers with subsidiary decision - making to formulate reasonable production olan.
