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,并设计了相应的遗传算法对其求解,通过实例计算表明,该算法对该问题是可行和有效的.For staging transportation networks, a optimal combination model of multiple transportation mode was proposed. By constructing a virtual transportation networks, the original problem was converted to a specific shortest path problem. A genetic algorithm for solving this problem was designed and applied, an example to this project, which indicated that this method was feasible and effective.
