改进AHP-灰色关联分析的给水厂排泥水处理工艺优选模型

Improved AHP Assessment and Grey Relational Analysis Model for Optimizing Waterworks Sludge Treatment Process

针对目前给水厂排泥水处理工艺流程甑选过程中存在的若干问题,以灰色关联分析为骨架建立给水厂排泥水处理工艺优选模型。通过最优传递矩阵对传统层次分析法进行改进,解决了传统层次分析法判断矩阵一致性修正的难题,并采用改进的层次分析法确定模型权重分配集合。以重庆某电厂净水站排泥水处理工艺设计为实例,介绍该模型的计算流程以及评价方法,并运用模型对工艺流程进行评判,得出适合该电厂净水站排泥水处理的最优工艺。

The goal of AHP-Grey Relational Analysis model is to solve problems during selecting the best waterworks sludge treatment process. And grey Relational Analysis is to confirm the compactness between the ideal process and candidate process. Moreover, weighting system was determined by the three-mark matrix and consistency analysis of judgment matrix for traditional AHP was improved by the optimum transfer matrix. Base on these theories, AHP-GRA model was established. A case study was addressed with the selection of waterworks sludge treatment process in Chongqing. It is found that this model is legitimate and credible.
