基于DEA模型的公共自行车系统效率评价
Assessing efficiency of public bicycle system by DEA
摘要
Abstract
Efficiency assessment is effective and necessary to guarantee sustainable operation of public bicycle system (PBS).To balance costs and benefits,a DEA efficiency assessment model for PBS was built.Six possible scenarios were used to evaluate efficiency in typical Beijing regions with built PBS.The general efficiency of PBS is high and returns increased after scaling up.Scenarios analysis helps to optimize allocations.Better uses of inner elements of PBS are helpful to improve PBS efficiency.According to DEA projection principle,roadmap for transition from DEA inefficiency to efficiency is explored,such as cost adjustment strategies for different scenarios.These data could benefit PBS policy making in the Beijing transportation system.关键词
