摘要
考虑到小型污水厂工艺选择受到很多不确定性或模糊性信息的影响,将模糊综合评判法与灰关联聚类分析理论相结合,在多层次指标体系的基础上,建立了一种新的定量综合评价模型——多层次模糊灰关联聚类分析综合评价模型,该模型使灰色关联分析法得到量化标度——最大关联度,并根据灰关联聚类值和最大关联度的大小来评判方案的优劣,其评价结果更接近实际情况。将该模型应用到工程实例中,所得结果与实际情况一致。
Considering that the selection of technology for small sewage treatment plant is affected by much of uncertainty or ambiguity information, a new quantitative evaluation model, namely multi-level fuzzy comprehensive evaluation model based on grey relational clustering analysis is established by combining the fuzzy comprehensive evaluation method with grey relational clustering analysis theory and based on the multi-level index system. This model makes the grey relational clustering analysis method to have a quantitative degree, namely maximum correlation degree. The good or bad of a scheme is evaluated based on the gray relational clustering value and the maximum correlation degree, and the result is closer to the actual situation. The application result of the model in an engineering case is the same with the actual situation.
