需求不确定的两阶段的报童扩展定价模型
首发时间:2013-07-12
摘要:本文将市场的销售分为两个时期,并在两阶段的需求函数中引入风险因子,说明了在风险因子大于零的情况下,为了使零售商与供应商、消费者之间所形成的供应链的整体效益得到提升,零售商常常采用降价销售策略。并进一步讨论了两阶段的需求函数下零售商如何制定最优的定价策略以及定价数量策略以实现利润最大化,得出了在考虑缺货损失因子下,适当的降价有利于提高零售商的最优订货量,进而最优化期望利润,并在风险度量准则条件风险估值CVaR下对该风险模型下的策略进行度量和分析,进而为零售商管理风险和规避风险提供依据。

Demand uncertainty of newsvendor extension model with two-stage pricing
Abstract:ISales can be divided into two periods ,this paper introduces this risk factors in two phase of the demand function ,and shows that under the condition of the risk factor that is greater than zero,in order to make the overall efficiency of the supply chain which is formed by retails, suppliers,and customers improved,retailers often adopt the price sales strategy.And the paper further discusses that under the two stages of the demand function,the retailers are how to develop the optimal order quantities and the pricing strategy in order to realize the profit maximization.It obtained that the appropriate price sales can improve the retailer's optimal order quantity,and then increase the optimal expected profits. Under conditional value at risk criterion,the paper measures the risk of the model and makes some analysis,which provide some suggestions for retailers to manage risk and avoid risk.
