基于AHP三角模糊数和可变模糊集理论的绿色施工评价研究

Green construction evaluation based on AHP triangle fuzzy number and variable fuzzy set theory

绿色施工的评价是一项多目标且复杂的问题,为了评判项目的绿色施工评价等级,从资源、技术、管理、环境以及成本入手构建评价体系,并进一步细分为18个二级指标。将AHP与三角模糊数结合确定指标权重,基于可变模糊集理论建立起一套包含定量、定性分析指标的计算模型,施工等级共分为优、良、合格,不合格四种,通过此模型得到项目的绿色施工等级。最后针对济南某项目进行绿色施工评价,评价结果证明该方法具有实际意义,可作为提高项目绿色施工水平的参考。

The evaluation of green construction is a multi-objective and complex problem.To assess the green construction rating of the project,this paper constructs the evaluation system from resources,technology,management,environment and cost,and further subdivides it into 18 secondary indexes.The weight of each index is determined with the combination of AHP and triangle fuzzy number.Based on the theory of variable fuzzy set,a set of calculation model including indexes of quantitative and qualitative analyses is established.The construction can be graded as one of the four types:excellent,good,qualified and unqualified.Through this model,the green construction grade of the project is obtained.Finally,the green construction evaluation of a project in Jinan is carried out,and the evaluation results prove that the method has practical significance and can be used as a reference to improve the green construction of the project.
