乘客分布不均条件下DRC公交运行周期优化

DRC bus operating cycle optimization with nonuniform passenger trip distribution

根据乘客出行实际,对乘客出行分布不均条件下单车模式DRC运行周期的优化方法进行了研究。根据乘客分布的不均匀性,建立了单个乘客的出行成本函数。以乘客出发时间窗要求和车容量等为约束,乘客出行成本最小为目标,构建了运行周期优化模型。并基于遗传算法,设计其求解算法。经实验分析,获得了不同出行分布下的DRC最佳运行周期和运行周期与总成本之间的相互影响关系。

According to passengers＇reality,the operating cycle optimization problem of the DRC bus is studied.The individual passenger utility function is rebuilt because of trip distribution is uneven.The passenger departure time window requirement,vehicle capaci-ty,and so on are all considered as constraint conditions,the minimum total travel cost as the target to build the operating cycle optimization model,the genetic algorithm is de-vised to obtain the best period.An experiment is carried out.Through this experiment, the DRC operation cycle is obtained under different demand distribution,and the relation ship between the operation cycle and total cost is also obtained.
