多目标稳定性网络优化模型是多目标优化模型的改进，文中以南昌市2000-2006年机动车辆管理处累计的历史数据为例，采用广义矩估计方法对所提出的多目标稳定性网络优化模型进行了实证检验．结果表明，改进后的优化模型比传统网络优化模型对网络优化的结果有相当程度的改善，采用多目标稳定性网络优化模型优化现实交通网络具有相当的适应性和稳定性．

The multi-objective optimization problem is one of the hotspots in the research for the current optimization problem. The optimization model of multi-objective stability network is an improvement of multi-objective optimization model. We took the accumulated historical data of Nanchang City Motor Vehicle Administration from the year of 2000 to 2006, and tested the proposed optimization model of multi-objective stability network by using the generalized method of moments. The results show that the network optimization has been improved to some extent by using the optimization model of multiobjective stability network and has good suitability and stability in optimizing real traffic network.
