报贩(NV)问题假定剩余库存的回收/清仓价格是问题的给定参数。在本文中，我们放宽了这一假设，考虑了以打捞/清理价格为决策变量的NV问题。本文从NV问题和清仓/降价/动态定价的文献中，建立了三个随机模型。在第一个模型中，我们假设季节性需求是外生的和随机的，而季末需求是内生的和确定性的。第二个模型对第一个模型进行了扩展，假设季末需求是内生的和随机的。最后，第三个模型认为季节需求和季末需求都是内生的和随机的。我们给出了求解随机优化问题的求解程序。我们还进行了敏感性分析，以评估最优预期利润和订货量对不同问题参数的敏感度。具体地说，我们发现最优预期利润对单位变动成本、平均季节需求和季末需求的市场潜力最为敏感。我们的模型将对那些销售季节短、季末剩余库存清仓销售的零售商有用，这样在季初只有一次补货机会，并且根据剩余库存和季末需求模式确定清仓销售的残值价格的单一机会。最后，对未来的研究方向进行了展望。
The newsvendor (NV) problem assumes that the salvage/clearance price at which the leftover inventory is disposed of is a given parameter of the problem. In this paper, we relax this assumption and consider the NV problem with the salvage/clearance price as a decision variable. We have drawn from the literatures on the NV problem and clearance/markdown/dynamic pricing to develop three stochastic models in this paper. In the first model, we assume that while the seasonal demand is exogenous and stochastic, the end-of-season demand is endogenous and deterministic. The second model extends the first model by assuming that the end-of-season demand is endogenous and stochastic. Finally, the third model considers that both the seasonal and end-of-season demands are endogenous and stochastic. We have provided solution procedures for solving the stochastic optimization problems. We have also performed sensitivity analyses to assess the sensitivity of the optimal expected profit and order quantity to different problem parameters. Specifically, we have found that the optimal expected profit is most sensitive to the variable cost per unit, mean seasonal demand and market potential of end-of-season demand. Our models will be useful for retailers of products with a short selling season and a short end-of-season period for clearance sale of leftover inventory such that there is a single replenishment opportunity at the beginning of the season and a single opportunity for setting the salvage price for clearance sale based on the leftover inventory and end-of-season demand pattern. The paper is concluded with possible directions for future research.
