Based on Entropy Weight and Fuzzy Comprehensive Evaluation Ecological Benefits of the Project—Analysis on Cold-Formed Thin-Walled Steel Residential Structure

Abstract

In this article, the entropy weight and fuzzy comprehensive evaluation methods is applied to Ecological Benefit of cold-formed thin-walled steel residential structure. Designed indicators system of Ecological benefits about cold-formed thin-walled steel residential structure, we divided into nine indicators in the system, then we grant questionnaire through selecting experts of project benefits Evaluation and experts on study about cold-formed thin-walled steel residential structure, Scoring the importance of eco-efficiency indicators, Using the Entropy weight to determine the weights of evaluation indexes, then combining with fuzzy comprehensive evaluation model, comprehensive evaluation on a variety of factors is made, analyzing ecological benefits about cold-formed thin-walled steel residential structure, eventually the result of Comprehensive Evaluation of Ecological benefits about cold-formed thin-walled steel residential structure is obtained.
