为响应动态需求,提出基于更新时间的路线更新策略对路线进行实时在线调整。并建立充电模型为有充电需求的路线分配充电站。最后给出实例仿真路线更新过程。以策略运行时间和总额外成本作为评价指标对更新时间进行参数分析。结果显示更新时间越少的策略能够快速响应需求及降低成本。随着更新时间的增加,需要处理的动态需求和充电次数增多导致策略运行时间和成本增加。最长的策略运行时间在可接受范围之内,说明策略具有可行性和实用性。
In response to the dynamic demand, a route update strategy based on update time is proposed to adjust routes online in real time. And establish a charging model to allocate charging stations for routes that have charging needs. Finally, an example simulation route update process is given. The strategy running time and total extra cost are taken as the evaluation indexes to analyze the update time. The results show that the less time-to-update strategy can respond quickly to demand and reduce costs. As update times increase, the dynamic demand and charging times that need to be addressed result in increased tactical uptime and costs. The longest strategy run time is within the acceptable range, indicating that the strategy is feasible and practical.
