基于改进隶属度转换算法的绿色施工模糊综合评价

The Fuzzy Comprehensive Evaluation of Green Construction Based on the Improved Membership Transformation Algorithm

针对施工活动中绿色施工的合理评价问题,首先,建立绿色施工二级评价指标体系,其次,应用层次分析法(AHP)确定各指标的重要性权重,在此基础上建立绿色施工模糊综合评价模型,并根据指标体系的结构特点,应用改进的隶属度转换算法识别对目标分类不起作用的冗余指标隶属度和指标隶属度中的冗余数值,选择对绿色施工分类起作用的"有效值"参与计算目标隶属度,得到切合实际的评判结果。最后,通过工程实例验证该方法的可行性。

For the rational evaluation of green construction in the construction activities,a two-levels index system was proposed firstly in the paper,secondly,the important weight of each index is determined by the application of analytic hierarchy process（AHP）,on this basis,the fuzzy comprehensive evaluation model of green construction is established,further more,based on the structural characteristics of the index system,the redundant index memberships as well as the redundant data which have not work to the target classification are identified by application of the improved membership transformation algorithm,the ＂available values＂ which have work to the classification of green construction are selected to calculate the objective membership so as to obtain the realistic evaluation results.Finally,the feasibility of the method proposed in the paper is proved through the construction example.
