模糊数学在道路工程质量评价中的应用

为分析反映道路工程质量的多种因素，包括可量化的定量因素及无法量化的定性因素，将模糊数学理论应用到道路工程质量评价中，并采用层次分析法区分不同因素指标的权重差别，根据类因素及次一级因素指标层对上一级评判目标影响的相对重要程度，由专家打分，形成判断矩阵，分别经过层次单排序，层次总排序，最后进行综合评判.按照最大隶属度原则，可以确定道路工程质量的等级.从而建立了一种对道路工程质量进行评价的多目标、多层次的模糊评价模式.结果表明，采用系统分析法和模糊综合评判对道路工程中的工程质量加以描述与评判是非常合理的.

Application of fuzzy decision in evaluation on road engineering quality

In order to analyze such factors to reflect quality of road engineering as quantitative and qualitative indexes,the fuzzy mathematics method was applied to evaluate the quality of road engineering,and the analytic hierarchy process was used to distinguish the weight difference of various factor indexes and form the judgment matrix based on the importance of classified index level and sub-class index to the judge target.The synthesis evaluation was carried on after hierarchy single compositor and general compositor were done.According to the most subjection principle,the grade of quality of road engineering was determined. So the fuzzy evaluation model of multi-targets and multi-levels on quality of road engineering was established.The result indicates that the method is reasonable to evaluate the engineering quality in road engineering.
