公共自行车租赁系统锁桩数学模型的研究与实现

Research of Lock Pile Mathematical Model of Public Bicycles Rental System

以某城市公共自行车系统运行数据作为研究背蓄，通过布局网络优化处理，分别统计各站点每天及累计的借车频次和还车频次，并对所有站点按累计的借车频次和还车频次分别排序，采用模拟数据拟合分析统计，计算数据中出现过的每张借车卡累计借车次数的分布情况，找出自行车用车的借还车站点之间（非零）最短距离与最长距离，以合理的数学模糊评估的方法，分析满足人们需求的站点分布和锁桩数量配置需要情况，同时根据各站点借车与还车差额情况，结合数据分布图清晰形象得出公共自行车服务系统的其他运行规律，提出改进建议。

This research, taking a city public bicycle system as the research background and optimizing the net- work layout, counts respectively borrowing and retuning frequency of the public bicycles in every site every day, and then sorts all the borrowing and retuning frequency. By using simulation data and analysis statistics, the distri- bution of the numbers of borrowing and returning frequency of each card is shown and the shortest and longest dis- tances of bicycle - borrowing and returning sites are very clear. Then, with the method of fuzzy assessment of math- ematics, the site distribution and lock piles which will meet the citizens＇requirements can be analyzed. So, accord- ing to the difference of borrowing and returning in every site and the data, other operations of public bicycle service system will be shown clearly and then the suggestions for improvement of public bicycle service system will be fol- lowed.
