    摘要

    共享自行车逐渐成为我国居民短距离出行的主要方式之一,但共享自行车的投放与用户需求不平衡的问题仍待解决。针对共享自行车的投放位置和规模的问题,提出了共享自行车区域投放和虚拟站点的概念,构建了共享自行车网络系统,建立了共享自行车区域投放双层规划模型。上层模型以系统用户总的出行成本最小为目标,考虑了企业、用户等约束条件,为系统最优模型;下层模型为网络用户均衡模型,并提出了混合遗传算法与粒子群算法求解该模型。最后,用某中等城市共享自行车出行数据进行分析,验证模型与算法的实用性。结果表明,该模型能同时确定投放区域虚拟站点的选址及规模,为共享自行车的投放提供了科学合理的依据。

    Abstract

    In recent years, bicycle sharing system has gradually become one of the main ways of short distance travel for residents, but the problem of unbalanced between the allocation of bicycles and user's need remains to be solved. In order to study the location and allocation of shared bicycles, the concept of shared bicycle regional allocation and virtual station is presented, a shared bicycle network is built, and also a shared bicycle regional allocation planning model which based on bi-level programming is proposed. The upper model aims at minimizing the total travel cost of users, and considers the constraints of enterprises and users, which is the optimal model of the system, while the lower part is a system user equilibrium model. A hybrid genetic algorithm and particle swarm optimization algorithm is proposed to solve this model. Finally, a case study is conducted on the background of shared bicycle travel data in a mediumsized city, to verified the effectiveness of the model and algorithm in the actual. The result shows that this model can determine the location and allocation of the virtual stations in each region, thus can provide a scientific and reasonable basis for the deployment of sharing bicycles.
