摘要
将灰色关联聚类法引入评价指标权重的确定,在物元分析的基础上,建立了基于聚类权重的区域水环境质量综合评价物元模型。通过实例分析将该模型与其它评价方法进行比较。结果显示,该模型弥补了模糊综合评判法、灰色聚类法的不足,评价结果合理,信息利用率高。
The matter elements model, based on clustering weight for evaluation of region water environmental by combining the grey relation -cluster method, which is adopted to calculate the weights of each criterion. The model is applied in the regional water environmental quality evaluation of Jinchang ciry, then the result is compared with that fuzzy synthetic evaluation and grey cluster analysis, which shows that the model makes up for insufficiency of fuzzy synthetic evaluation and grey cluster analysis, and is more reasonable than before .
