摘　　要：针对现有公交线网方案的评价选优方法中存在难以同时刻画不同类型不确定性等问题,提出了集对-熵组合赋权分析法来进行公交线网方案评价选优。将把研究系统分成同、反两个局部分量,以刻画两个事物之间不同类型的内在联系程度,增强了系统整体分析的准确性,减少了不确定性;引入熵值理论来确定指标的客观权重,减少了主观因素干扰等不确定性。实例分析表明:该模型能够从整体和局部上剖析系统内在的联系,具有计算过程简单、使用方便等特点。Due to the disadvantages that many current public transport network optimization evaluation methods were difficult to portray different types of uncertainty at the same time, the public transport network optimization scheme based on set pair and entropy analysis was proposed. The research system in the proposed method was divided into two local components, same and opposite, to describe the relationship degree with different types between two things. Comprehensively considering the above two local components, the accuracy of the system overall analysis was enhanced and the uncertainty was reduced; at the same time, the entropy theory was introduced to determine the objective weight of index, which reduced the uncertainty, such as the disturbance of subjective factors. The case analysis shows that the model can analyze the system of internal relations from the overall and partial aspect, and its computational process is simple and easy to use.
