多时窗下公共自行车租赁点选址布局模型研究

Research on Selection and Layout Model for Rental Station of Public Bike Based on Multiple Time-Window

作为城市准公共交通,公共自行车对促进完善公共交通系统、助力城市发展具有重要意义。在提出租赁点需求集对效应、还车滞后效应以及考虑生命周期的基础上,建立了多时窗下以用户和供给方双边成本最低、同时满足租还需求、周转率以及加权平均步行距离等约束的混合整数规划选址布局模型。通过对模型求解,可以得到空间中实际将要修建租赁点的位置以及修建租赁点处所需布置的自行车数和锁桩数。

Public bikes （PB）, a kind of transport, play an important role in improving public transit system （PTS）and promoting city development. According to shortcomings in previous researches concerning the selection andlayout of rental stations （RSSL） for urban public bike system（PBS）, this paper conducted some researches on themodel. Then, on the basis of proposing the Gather Effect （GE）, the Lag Effect （LE） and the Life Circle （LC）, itdeveloped a mixed-integer？programming model for RSSL problems so as to minimize the bilateral cost, which issubjected to the demand of renting and returning, turnover rate and weighted average walking of users. By solv-ing the model, the spatial position of rental stations may be actually set up, and the number of bikes and lock-stakes can be calculated.
