一类短生命周期产品的订购与定价联合决策模型

研究了一类短生命周期产品在价格依赖(加和)随机需求下的订购与定价联合决策问题。根据一类产品单周期两阶段销售的营销特性,首先以集中式系统的视角研究了其联合最优决策,并应用随机动态规划模型刻画了集中式系统的最优决策;然后,证明了其期望利润函数关于各决策矢量的凹性,并给出了确定最优决策矢量的迭代搜寻算法;最后,应用数值实验对决策结果进行了分析。研究表明:系统的绩效主要来自于销售的第一阶段,经营者应当更注重该阶段利润的挖掘。

Jointed Decision Model on Ordering and Pricing for Short-Life-Cycle Product

The jointed decision question on ordering and pricing for a short-life-cycle product is studied under the stochastic demand depended on selling prices(only focus the additive stochastic demand in this paper).According to the marketing practices, the retailer sells his product in different periods with different marketing policies.Firstly,the jointed decision question is used for a centralized system with a stochastic dynamic programming model.Then,the expected profit function of the whole system is proved to be concave on decision vectors,respectively,and the iterative search algorithm is given to find the optimal decision vectors.Finally,the characteristics of the decision method are analyzed with some simulations.Results show that the system performance is mainly from the first selling period,and dealers pay more attentions to the period to find out more profits.
