改进的集对分析水质综合评价方法
Comprehensive evaluation method of water quality based on improved set pair analysis
摘要
Abstract
This paper proposes an improved set pair analysis（SPA） method using malleability of original relation degree to solve the problem of subtle differentiation between uniform,different and reverse in standard SPA.A water quality evaluation model was developed with this method for evaluation of the excellent and inferior tendency degree of the samples in the corresponding rank.It introduces a discrepancy coefficient and an entropy method to optimize the index system and adopts a superstandard multiple method to determine the synthetic weight of index.Combined with a fuzzy method,it was applied to evaluation of the surface water quality in Shanxi province.A comparison of the SPA method with gray classification method,synthesis index method,fuzzy neural networks and projection pursuit method,shows that its evaluations are closer to the real situation.It is a better method for evaluation and decision-making of water environment and has good potential application.关键词
