A Semi-Analytical Solution for a Newsboy Problem with Mid-Period Replenishment
研究了经典报童问题的一个常见变体：销售期间除期初补货外，还有一次中期补货机会。提出了基本模型和半解析求解方法，数值解揭示了有趣性质，表明该扩展使问题更具管理挑战性，但可实际求解并带来显著利润提升。
This paper is an exploratory study of a very common variation of the classical newsboy problem: in addition to the supply at the beginning of the sales period, an additional replenishment opportunity exists sometime during the sales period. A basic model for the problem is presented and a semi-analytical solution procedure is developed. Numerical solutions obtained reveal certain interesting properties of the model. The paper shows that the replenishment extension makes the newsboy problem much more challenging managerially and also that it can be practically solved with significant profit implications.
