摘　　要：在分析铁路选线领域知识特点的基础上 ,建立了铁路选线多方案综合评价模型 ,阐述了评价铁路选线方案优劣的综合评优方法 ,即带偏好信息的设计方案多目标灰色关联度决策方法 ;提出了根据线路方案设计信息直接获取铁路选线方案的评价指标信息和自下而上逐层构造决策矩阵并进行多目标综合评价的思想。本文提出的方法已被成功地用于铁路新线设计智能By analyzing the features of knowledge structure in railway location, this paper sets up a layer model. A optimal method for evaluating schemes of railway location synthetically has been illustrated, that is multi objective gray relevant optimized decision making model of engineering system with preference information of schemes. An idea to produce the information for constructing the judgement matrix from route schemes is presented. By using the step by step evaluating procedure, the synthetic evaluation of railway location schemes can be realized. The method of this paper has ben used successfully in intelligent CAD system of railway location.
