摘要
针对目前污水处理工艺方案选择所采用的层次分析法、模糊综合评判、灰色关联分析法存在的主观确定权重及过分依赖因素权重的缺点,将熵权理论、模糊隶属度、灰色关联分析法相结合,建立了熵权模糊灰色关联分析耦合模型。模型中引用信息熵所反映数据本身的效用值来计算指标的权重系数,有效地避免了由于人的主观因素而形成的权重分配偏差。运用该模型进行实例研究,取得了较为满意的效果。
In view of the shortcomings of the subjective determination of weights and the excessive reliance on the weight factors in current wastewater treatment process used in the analytical hierarchy process, fuzzy comprehensive evaluation and grey correlation analysis, the study combined entropy theory, fuzzy membership and gray relational analysis to establish entropy fuzzy grey correlation analysis coupled model. The model used the effectiveness of entropy to calculate the index weighting factor, effectively avoided the weight distribution deviation caused by the subjective factors. The model has applied in practice and satisfactory effect was obtained.
