摘要
针对模糊矩阵综合评判存在失效的问题,运用可信性理论,将判断属性值好坏的模糊性语言描述,用建立在可信性空间的模糊变量来表示,并以期望值纯量的形式来刻画。提出了基于模糊变量期望值算子的综合评判模型,针对此模型的不足和局限性,又提出了修正模型,并给出了相应的算法。模型实例分析结果表明:该模型具有很强的适用性和有效性。该成果为模糊性决策系统提供了一种新的处理方式,具有一定的参考价值。
To overcome the failure associated with the fuzzy matrix comprehensive evaluation,the study applies credibility theory,uses the fuzzy variable based on credible space to describe the vague language,which is used to assess the attribute good or bad. Therefore,the study proposes a comprehensive evaluation model based on fuzzy variable expected value operators. To mitigate the shortcomings and limitations of the model,the paper also introduces an improved model,and provides a corresponding algorithm. The case study shows that the model is very effective and widely applicable. The study provides a new processing method for fuzzy decision system.
