摘　　要： 针对多目标的决策问题,依据模糊识别理论提出一种多目标多维自反馈模糊决策模型.首先根据给定的目标初始权重计算加权综合决策值;然后利用单指标模糊识别方法计算加权综合决策值的模糊划分;最后依据成因分析并用决策值的模糊划分,计算出目标的权重.重复上述计算过程,可得到满足精度要求的加权综合决策值及其模糊划分,根据计算结果可判定决策类别和优劣排序.炼钢企业评价决策实例表明,所提出的模糊决策模型是有效的. Aiming at the problems of multiple object decision making,based on the theories of fuzzy recognition,the pattern of multi-objective and multi-dimensional fuzzy decision making with feedback is presented in this paper. According to the given weights,the weighting integrated value of decision making is computed. Then,the method of fuzzy recognition with single index is employed to calculate the fuzzy classification of the integrated value. Finally,according to the cause analysis,the fuzzy classification of the integrated value is used to compute the weights of indexes. In the same way,repeating the above processes,the weighting integrated value and fuzzy classification with given accuracy are gotten at the same time,the classification and sequence of decision making set are also gained. The example of steelmaking enterprises evaluating shows the effectiveness of the presented model.
