摘要
建立M/M/1/∞/∞与M/M/C/∞/∞排队模型,对比分析单路排队多通道服务系统和多路排队多通道服务系统的效率;以收费站建设运营成本、闲置损失成本与车辆等候成本三者成本之和最小为目标,探讨ETC车辆安装率与的ETC车道配置率关系,结果表明在不同ETC车辆安装率情况下,ETC车道合理配置可有效控制总成本。
The paper established M/M/1/∞/∞and M/M/C/∞/∞queuing models,and compared the single-channel queuing multi-channel service systems and the multi-channel queuing multi-channels.With the goal of minimizing the sum of the construction and operation cost of toll station,idle loss cost and vehicle waiting cost,the paper discussed the relationship between the installation rate of ETC vehicles and the allocation rate of ETC lanes from the three aspects of construction operation cost,vehicle waiting cost,and idle loss cost.The results show that the reasonable allocation of ETC lanes can effectively control the total cost in the case of different ETC vehicle installation rates.
