针对轴-辐式机场长途巴士线网的发车时刻问题,构建时空网络,分析乘客到达机场的行为与过程;基于航班起飞时刻,在乘客的候机与换乘时间上限约束下,建立巴士时刻表优化模型,并设计基于矩阵式编码的遗传算法进行求解.通过分析不同候机与换乘时间上限的组合对运营成本的敏感性,得出合理的运营时刻表. Aiming at the departure time of the long-distance bus network at the axis-spoke airport, the time-space network is constructed to analyze the behavior and process of the passengers arriving at the airport. Based on the departure time of the flight, the bus schedule is established under the constraints of passenger’s waiting time and transfer time limit Optimize the model, and design genetic algorithm based on matrix coding to solve.The reasonable operating schedule is obtained by analyzing the sensitivity of the combination of different terminals and transfer time cap to operation costs.
