立交方案的评价 ,需涉及到多项指标 ,方案决策时 ,由于多个目标同时存在 ,影响因素繁多 ,而许多因素自身又无法定量描述 ,采用常规评价即经典的数学方法是不够严格的 ,也难于直接判断。本文在互通式立交选型方案研究中 ,拟结合以往的定性分析研究 ,作进一步的定量分析 ,借助评价指标体系 ,并在此基础上进行模糊评价 ,以寻求整体最优方案
Overhaul program evaluation involves many indicators. In program decision-making, due to the simultaneous existence of multiple goals, many influential factors, and many factors themselves can not be described quantitatively, the use of conventional evaluation that is the classical mathematical method is not strict enough, Difficult to judge directly. In this paper, the study of the selection scheme of the interchange type, it is proposed to combine with the previous qualitative analysis and research for further quantitative analysis, with the help of the evaluation index system, and on this basis to conduct fuzzy evaluation to seek the overall optimal solution
