摘　　要：为了解决旅客换乘过程中多种运输方式的协调问题,根据客运换乘网络的特点及结构,以旅客旅行时间最短和总出行费用最小为优化目标,建立了综合客运换乘网络优化模型.通过加权求和,将多目标函数转化为单目标函数,给出了用遗传算法求解的步骤,并用算例进行了验算.结果表明:本文建立的模型可行,算法有效.To resolve multi-modal transport coordination problem during passenger transfer, a optimization model of passenger transfer network for integrated transformation, with the shortest travel time and the least expense taken as optimization objectives, was built according to the characteristics and structure of passenger transfer network. Then, the multi-objective functions were integrated into a single-objective function through weighted summation of the shortest travel time and the least expense. The model was solved by genetic algorithm, and the solution procedure was described. An application example was demonstrated, and the results verified the effectiveness of the proposed model and algorithm.
