【摘要】：城市公共自行车系统旨在满足当地居民"最后一公里"的出行需求,因其低成本且环保的特点受到越来越多城市的欢迎,但整个系统涉及人流量、出行方式及交通状况等多层因素,难以构建数学模型进行定量描述。依据某市公共自行车系统的运营情况,采用系统建模的方式,构建基于Plant Simulation的公共自行车系统仿真模型,以站点服务度和设施利用率为评价指标,对各个租赁站点的配车数进行了分析。利用敏感性分析和迭代相结合的方法,在平衡服务质量和设施利用率的情况下,对各公共自行车租赁站点的配车数进行了优化,仿真结果表明优化后的配车数有利于改善系统的服务质量。
[Abstract]:The urban public bicycle system, which is designed to meet the "last kilometer" travel needs of local residents, is becoming increasingly popular in more and more cities because of its low-cost and environmentally friendly characteristics, but the entire system involves human flow. It is difficult to construct a mathematical model to describe the multi-layer factors such as travel mode and traffic condition. According to the operation situation of public bicycle system in a certain city, the simulation model of public bicycle system based on Plant Simulation is constructed by the way of system modeling, and the service degree and the utilization ratio of facilities are taken as the evaluation index. The number of cars assigned to each rental station is analyzed. Using the method of sensitivity analysis and iteration, under the condition of balancing the quality of service and the utilization ratio of facilities, the number of public bicycle rental stations is optimized. The simulation results show that the optimized number of cars is conducive to improving the quality of service of the system.
