考虑供需异质性的共享泊位滚动时域分配模型
Allocation of shared berths in rolling time domain considering heterogeneity of supply and demand
摘要
Abstract
[Background]Existing information platforms for shared berth allocation cannot respond to dynamic random demands in real time and rarely allocate berths based on user requirements.Ad-ditionally,the platform's income can be further optimized.[Objective]To construct and solve a roll-ing time-domain allocation model for shared berths while considering the heterogeneity of supply and demand to optimize the allocation of parking resources and maximize total social benefits.[Methods]Based on the classical shared-berth allocation model framework,this study comprehen-sively considers the heterogeneity of parking supply and demand as well as low-carbon benefits.An"on-demand rental"strategy is devised and an artificial fish shoal-genetic algorithm is developed.Numerical simulation experiments are conducted using Matlab.[Data]The total number of parking spaces,the number of available berths,and the temporal and spatial characteristics of parking lots in the Good City Time residential district of Longhu City,Shapingba District,Chongqing,are investi-gated on-site.[Conclusions]The model achieves a berth turnover rate of approximately 80%,a user acceptance rate and a request period acceptance rate of approximately 90%,and a low-carbon in-come ratio of approximately 6.56%.Compared with the classical model,it reduces the parking-space rental cost significantly and offers more system benefits.Moreover,its turnover rate is similar to that of the classical parking-allocation model.Finally,a sensitivity-analysis experiment is performed,and the result shows that as demand increases,the revenue first increases and then decreases,the berth turnover rate changes from abrupt to stable,and the decline in the user acceptance rate and re-quest-period acceptance rate increases gradually.[Applications]The findings of this study provide a theoretical reference for parking allocation and management decisions on shared platforms.关键词
