摘要
考虑泊位空间属性和服务时间弹性调整需求下的共享泊位双向拍卖机制的设计,对于提高共享参与者的参与度和系统效率具有重要意义。设计考虑共享泊位时空属性的双向拍卖机制,以社会福利最优为目标,构建基于双向拍卖机制的共享泊位分配模型;为保证用户能够真实竞价,基于VCG(vickery-clarke-groves)拍卖定价机制构建共享泊位定价模型,设计算法并开展算例分析。算例计算分析表明:相较于传统的共享预约模式,双向拍卖机制在交易成功率、成功交易单元数和平台收益分别提升了25%、28%和198元。
The design of two-way auction mechanism of shared berths considering the space attributes of berths and the elastic adjustment demand of service time is of great significance to improve the participation of sharing participants and system efficiency.The two-way auction mechanism of shared berths considering the spatial and temporal attributes was designed.Aiming at the optimization of social welfare,a shared berth allocation model based on two-way auction mechanism was constructed.In order to ensure that users could truly bid,a shared berth pricing model was built based on VCG(vickery-clarke-groves)auction pricing mechanism,and the algorithm was designed and analyzed by a numerical example.The calculation and analysis of the example shows that,compared with the traditional sharing reservation mode,the two-way auction mechanism has increased the transaction success rate,the number of successful transaction units and the platform revenue by 25%,28% and 198 yuan respectively.
