考虑医院停车用户紧迫程度和停车偏好差异的共享停车位分配优化问题, 引入了分配优先级和主观停车效用两个参数, 建立了以最大化考虑分配优先级的请求接受率为主目标, 以最大化总主观停车效用为次目标的共享停车位分配模型, 提出并对比分析了 3 种分配机制: 静态分配机制、动态分配机制和考虑急诊车位预留的动态分配机制. 研究表明, 本模型可以显著提高紧迫程度高和老年停车用户的请求接受率, 并为用户匹配更符合其停车偏好的车位; 平台管理者设置一定比例的急诊预留车位可以有效提高急诊类用户的请求接受率, 设置 8% 的 急诊预留车位可以使急诊类用户的请求接受率达到 95% 以上, 显著增加共享停车分配的综合 效益. 

In order to optimize the allocation of shared parking spaces for hospital parking users, the differences in urgency and parking preferences of hospital parking users are considered. Two parameters, assignment priority and subjective parking utility, are introduced, and a shared parking space allocation model with the primary objective of maximizing the acceptance rate of requests considering assignment priority and the secondary objective of maximizing the total subjective parking utility is proposed. Three allocation mechanisms are proposed and comparatively analyzed: static allocation mechanism (SA), a dynamic allocation mechanism (DA) and dynamic allocation mechanism considering emergency parking space reservation (IDA). The study shows that this model can significantly improve the acceptance rate of requests from urgent and elderly parking users, and match users with parking spaces that better meet their parking preferences. It can effectively increase the request acceptance rate of emergency parking users by setting a certain percentage of emergency reserved spaces.Setting 8% of spaces as emergency reserved spaces can keep the request acceptance rate of emergency parking users at a high level (above 95%) and significantly increase the comprehensive benefits of shared parking allocation.
