摘要
对2017年全国研究生数学建模F题“构建地下物流网络”进行了综述．明确命题背景和目的，并提出求解思路，分析答题过程中普遍遇到的关键问题，最后根据实际作答情况，对网络建模部分进行整体评价，并提出本题中关键的创新点．
The problem F of the 2017 14th Annual Chinese Graduate Mathematical Mod-eling Contest, Construction of underground logistics system network, is reviewed. The back-ground and motivation of the problem, and the methods and ideas for solving the problem is discussed and analyzed. Furthermore, the key problems commonly encountered in the answer process are analyzed. Finally, according to the actual response situation, the overall evaluation of the network modeling part is carried out, and the key innovation points in the problem are put forward.
