摘要
针对传统评价中单纯主观确定参评指标权重方法的不足,采用主观判断与客观评估相结合的信息熵权方法确定各指标权重系数,进而将模糊聚类与熵权确定权重综合应用于水质综合评价中,取得了较为满意的评价结果:避免了主观定权中人为因素的影响以及客观定权的不均衡性。
The assignment of the weight parameters in raw water quality is very important to the rationality of the result.Reasonable selection of pavement structure is important in highway design,which should be based on correct assessment of the structure.To avoid un-determintion and arbitrary judgements resulted from subjective opinions in a new approach corresponding to the complex problem is used.To ameliorate the inefficiency of means for proportion coefficient decision in the course of the evaluation of information system integration solutions,the weight coefficient is given by means of entropy coefficient and objective situation.This model is applied to pavement structure evaluation.The result shows that the model is effective and practical.
