通过研究总图设计的原则与目的,针对总图设计特点,简化了总图布置方案的综合评价指标体系,在此基础上建立了以总图布置运输方式经济性为对象的总图布置方案综合评价指标体系.利用关联熵法,结合复合物元的概念、信息理论,确定了参加评价指标的权重,反映了评价指标的重要性.针对总图设计综合评价指标较多,指标间关系复杂,评价层次较多的问题,以可拓设计评价方法为基础,建立了针对总图设计的综合评价模型.对总图设计方案经济性进行了量化分析,从整体最优的角度反映了总图设计的水平.结合实例,给出了基于运输经济性的总图设计推荐方案.
On the basis of the general transport layout principles and objective, characteristics of transport layout and eco- nomic analysis, the general transport layout evaluation system is set up. Adopted is the complex matter-element model, information theory, extension method and the partial entropy to determine the weight of the evaluation index. Aiming at the complex numerous indexes and correlations among them, considering each factor of the general transport layout, a new transport layout evaluation method is established. The economic conditions of transports is analyzed integrally, and a quantitative analysis of transport layout is made. A case study is conducted, and the economies global optimal option is selected by means of comparison.
