基于AHP与GRAY的综合评判之公路工程施工方案评价

层次分析法是一种系统化、层次化分析问题的多目标决策方法,而灰色关联分析方法是从信息的非完备性出发研究和处理复杂系统的理论。本文使用基于层次分析法和灰色关联度分析的灰色综合评判法,参考某公路工程施工方案评价体系,先用层次分析法确定影响施工方案合理性的五个因素的权重,然后利用灰色理论对所选取的五项指标进行了关联度分析,从而通过这两种评价方法相结合运用而进行的综合评判选出最合理的施工方案。

Analytical hierarchy process （ahp） is a systematic analysis of the problems and hierarchical multi-objective decision-making method. But the grey relational analysis method is such a theory that research and deal with the complex system from the completeness of the information. This paper based on the analytic hierarchy process （ahp） and grey correlation analysis of grey comprehensive evaluation method, reference to a highway construction program evaluation system.Use ahp to determine the weights of the five factors that affect the rationality of construction plan and then use the gray theory to analyze the five indicators for the correlation. Thus select the most reasonable construction scheme by combining the comprehensive evaluation with this two methods in the end.
