摘要
对可阶段化运输网络,提出了将路径选择与交通运输方式相结合的组合优化模型.通过虚拟一个运输网络,转化为一个与原问题等价的最短路径问题.先对网络进行优化,再设计相应的遗传算法对其求解.
For transportation networks that can be staging, we suggest a combination optimization model of multiple transportation mode. By constructing a virtual transportation networks, the original problem is converted to a specific shortest path problem. First optimize the network, and then this paper gives the application of genetic algorithm for this problem.
