经济圈公路网络布局优化模型研究

摘要

This paper presents a bi-level programming model based on genetic and simulated annealing algorithm to design the network of economic area in allusion to the features of economic circle road network.MATLAB is used to develop corresponding algorithm procedures, which is especially fit for solving large scale network optimization.At last, an example of road network in economic circle of the Yangtze River Delta is given to verify analysis, whose result shows the rationality of the method.%针对经济圈公路网络布局特点,建立一种基于遗传-模拟退火混合优化策略算法的经济圈公路网多目标双层布局优化模型,并采用MATLB开发了相应的算法程序进行求解,该算法尤其适合求解大规模网络优化问题.最后以长三角经济圈简化公路网络做实例验证分析,结果表明建立的模型和提出的解法效果良好,具有可行性.
