摘　　要：研究目的:近年来,中非之间的交通项目合作交流日益频繁。作为尼日利亚第一大城市,Lagos的经济整体水平近年来有了明显的提升,随着日益增长的客货运需求,轨道交通已经成为该地区城市交通规划的重点。本文旨在提出合适的线路方案,并针对Lagos地区轨道交通线路方案分析具有不确定、多属性的特点,采用合适的评价方法从众多可行路线方案中选取最优方案。研究结果:集对分析理论是一种新的处理不确定性多属性问题的评价方法,通过对不确定系统的定量分析,对不同方案的不确定性进行排序,从而得到最稳定的方案,即最优方案。本文首先采用集对分析理论建立了Lagos地区轨道交通线路综合评价模型,其次运用层次分析法确定指标权重,最后构建评价指标体系对多个备选方案进行评价,得到了最优方案。结果表明集对分析理论可用于轨道交通线路方案优选。集对分析;Lagos;轨道交通;线路方案;Research purposes： In recent years, traffic cooperation and exchange projects between China and Africa become more and more increasingly. As the biggest city in Nigeria, Lagos has obviously improved much in the economy recently. With the growing demand for passenger and freight traffic, rail transit has become the important part of urban transport plan. This paper intends to propose the appropriate track programs of rail transit in Lagos and select the optimum program from a number of programs with the best evaluation methods. Research results：Set pair analysis theory is a new method to deal with the uncertain and multiplex problems. Through quantitatively analyzing uncertain systems and sequencing the uncertainness of the different programs, the optimum program is obtained by establishing the integrated evaluation model for rail transit in Lagos with the set pair analysis theory, determining the index weight with analytic hierarchy process and establishing the evaluation index system for evaluation and estimation of a number of optional programs. The results show that the set pair analysis theory can be used for optimizing the track program of rail transit.
