基于预约需求的共享停车平台泊位分配方法

为解决在预约需求下，考虑预约时刻、时长及延时需求的共享停车分配问题，提出一种共享停车泊位分配模型. 以平台收益和停车步行距离为优化目标，将需求分为基本及延时两种情况，确定停车预约请求的分配策略. 根据模型结构，设计随机解集生成方法，利用蒙特卡洛法确定模型的最优解. 以医院停车场及周边停车场为案例，测试模型. 结果表明，模型能较好地服务于共享停车泊位的分配，实现平台收益与满足需求之间的平衡.

Shared Parking Space Allocation Method Considering Reservation Demand

This paper proposed a parking space allocation model to solve the parking allocation problem with reservation demand and the booking time, parking time and delay time are given. The profit of the system and walking distance users were set as the objectives. The demands were divided into basic request and delay request, and the model was then developed by collecting users' requests to determine the optimal allocation strategy. A random solution set generation method was proposed and a Monte Carlo algorithm was used to solve the problem. An example of a hospital and surrounding parking lots was used to test the model performance. The results illustrate that the proposed model can serve the parking space allocation problems and realize the balance between the system profit and user' demands.
