中文摘要：

当前，各高校《网络优化》课程的理论授课相对到位，但存在着一些严峻的共性问题：理论教学主宰课堂，实践教学没有得到体现；教学套路老化；评价体系不健全。为应对此严峻现状，河北联合大学引入了问题研究教学法，在教学中通过问题研究教学将数学建模的思想融入《网络优化》课程来充分突出实践教学，从而构建了基于数学建模平台的《网络优化》课程的“三位一体”教学体系。

英文摘要：

Currently,theory teaching of the Network Optimization course is very radical in many universities, but there exist some seri- ously common problems：class is dominated by theory teaching, while practical teaching hasn＇ t been embodied;teaching routine is obso- lete ; evaluation system is imperfect. To deal with those severe situations, we introduce the problem-research teaching method, draw the thoughts of mathematical modeling into the Network Optimization course to embody practical teaching by problem-research method in teaching process, and construct trinity teaching system of the Network Optimization course based on mathematical modeling platform.
