摘要
水质评价属于涉及定性和定量信息的不确定多属性决策问题,评估过程中依据的信息具有不完全性。可采用证据推理方法,把定性和定量信息转化成统一的分布式形式,通过集结较低层评价指标得到最上层指标的综合评价值,最后采用效用理论进行决策。实例评价结果符合实际情况,表明采用证据推理方法进行水质评估分析是可行的。
Water quality assessment involves multiple attributes of both a quantitative and qualitative nature with uncertainty,and there is incomplete information in the index system.Evidential reasoning(ER) method can be used to transform quantitative and qualitative information to uniform distribution.The general values of assessment can be obtained through aggregating the lower attributes,then decision is made using utility theory.The example demonstrates that the ER method is effective in water quality assessment and analysis.
