面向单周期制造商利益函数的单峰性分析

Analysis the Unimodality of the Single-period Inventory for the Manufacturers

在对面向制造商的单周期库存问题进行求解时,利益函数的单峰性成为优化算法构建的一个必要假设和基础。针对单峰性这个假设的真实性,结合问题特性和数学知识进行了分析。

The unimodality of the single-period inventory is the basic assumption for optimizing approaches. In order to modify this character, if the demand density function is unimodal, then the profit function is quasiconcave over the support of the distribution is provided.
