摘　　要：在对面向制造商的单周期库存问题单峰性研究的基础上,通过构建虚拟问题及类比分析,结合数学方法证明了二次订货条件下制造商利益函数的单峰性。Based on the analysis for the unimodality of the single-period inventory, that of the two-timing ordering inventory for the manufacturers is studied. In order to modify this character, the virtual model and the function for the sellers are analyzed. Then if the demand density function is unimodal, then the profit function is quasi-concave over the support of the distribution is provided.
