摘要
在模糊物元分析原理的基础上,结合水质评价的特点和海明贴近度的概念,提出了三标度法的模糊物元分析方法。在对水质进行综合评价时,把水质的分类等级作为物元的事物,以它们的各项评价指标及其相应的模糊量值构造复合模糊物元,通过计算与理想模糊物元之间的海明贴近度,实现对水样水质的等级评价和水样排序。在指标权重的确定上选取三标度法,使评分方法与决策者的语言习惯相一致,令构造出的判断矩阵更加直观准确。研究结果说明:该模糊物元模型简便、通用,计算结果较为客观和稳定,为水质综合评价提供了新的有效方法。
Based on the analysis theory of fuzzy matter-element, combining with the characteristic of water quality evaluation and the concept of Hamming approach degree, the fuzzy matter-element analysis model based on three-mark method was put forward in this paper. Regarding the water quality level as the objects of matter-element, constructing the compound fuzzy matter-element through various evaluation indexes and corresponding fuzzy value, the water quality evaluation and arrangement was achieved through calcu lating Hamming approach degree between the fuzzy matter-element and the standard （the best） fuzzy matter-element. This paper selected three-mark method, which can greatly meet custom of decision-maker, for the decision of index weight to make the estimation matrix more intuitionistic and correct. The effect of application indicated that the model was convenient, accurate, had objective and stable calculation result, and provided a new effective method for the comprehension evaluation of water quality.
