基于熵权-模糊综合评价的混凝土评价可行性研究
Feasibility Study of Concrete Evaluation Based on Entropy Weight-fuzzy Comprehensive Evaluation
摘要
Abstract
Taking concrete as an example, this paper uses the fuzzy comprehensive evaluation model based on entropy weight to quantify its green degree .The green degree of concrete was divided into four grades ( excellent, good, neutralization difference ), then the weights of evaluation indexes were determined by the more objective entropy weighting method , the membership matrix was established, and finally the green degree of concrete was calculated with the fuzzy comprehensive evaluation model in a weighted average way.Taking C50 high performance concrete of one beam structure of the fifth standard section of the second double line of Lanzhou -Sinkiang railway as the research object , and the principle of maximum membership degree as judgment basis , the green degree of the concrete is evaluated as average which is in accordance with the original document result .This empirical analysis shows that it is reasonable and feasible to use the fuzzy comprehensive evaluation model on the basis of entropy weight to evaluate the concrete, and it can also provide a theoretical basis and reference value for assessing the green performance of building materials .Furthermore, the calculation process of this method is much simpler.关键词
