为降低城市公共自行车调度过程中调度员凭经验确定各站点调度需求量的盲目性,提高调度科学性并缩减调度时间和成本,将城市公共自行车租赁站点调度需求量模型描述为最优化整数规划问题,考虑系统的稳定性和调度触发时间,以高峰时段系统的整体稳定性最强、调度启动时间最晚为目标建立公共自行车租赁站点调度需求量模型.针对该模型特点设计了十进制编码、二人竞赛选择、算术交叉、非均匀变异的遗传算法对模型进行求解.通过调度实例验证模型和算法的可行性,得到各租赁站点的最优调度需求量.结果表明,按照该模型求解出的调度需求量进行调度能够延迟高峰时段的调度启动时间至1.33h,较站点均一化存放率调度延迟0.67h,极大地延缓了调度启动时间并缩减调度工作量.
