摘　　要：针对电动汽车充电桩经典排队服务模型优化受限问题,为实现充电站运行效率和服务水平的实时跟踪和综合优化,满足随机输入充电车辆对个体服务指标的查询需求,提出了一种基于时间序列的动态优化排队模型R/R/n/∞/m,改进了经典排队模型必须假设输入过程和服务时间服从某种固定分布的约束,引入时间序列模拟了待充电车辆的动态排队过程,表达了充电车辆个体排队状态参数,获取了排队系统的整体状态指标。运用模型对镇江市电动汽车充电站充电桩的设置进行了优化,结果表明:模型能有效模拟和揭示充电站排队系统状态的动态变化,同时满足充电车辆的个体查询需求,实现充电站运行效率和服务水平的实时跟踪和综合评价,从决策层面优化了充电站的设施建设,提高了充电站的服务效率。Aiming at the limited problem of the classic queuing model used in the service optimization of electric vehicle charging piles,in order to achieve real-time tracking and comprehensive optimization of charging station operating efficiency and service level,and to meet the query requirements of randomly input charging vehicles for individual service indicators,a dynamic optimization queuing model based on time series R/R/n/∞/m is proposed.The model does not require the input process and service time of the queuing system to follow a fixed distribution.By introducing a time sequence,the dynamic queuing process of the vehicles to be charged is simulated,the individual queuing status parameters of the charged vehicles are expressed,and the overall status index of the queuing system is obtained.The model is used to optimize the setting of charging piles for electric vehicle charging stations in Zhenjiang City.The results show that the model can effectively simulate and reveal the dynamic changes of the charging station’s queuing system status,and at the same time meet the individual query requirements of charging vehicles,and realize realtime tracking and comprehensive evaluation of charging station operating efficiency and service level.From the decision-making level,the facility construction of the charging station is optimized and the service efficiency of the charging station is improved.
