【摘要】：为了使云模型能直观方便地表示以及计算多属性决策问题,并且适应专家给出的范围数据,对提出的属性圆表示多属性的方法进行了改造,从而通过属性圆来计算云模型的特征参数;给出了改造后属性圆的定义、性质和绘制过程,以及如何通过属性圆计算表示某决策级别的云模型特征参数,包括:定义决策系统、属性归一化、属性圆特征及性质、属性圆面积求法、基于属性圆的云模型计算;通过实例给出了云模型的计算过程和应用方案。根据数据处理和专家分析,计算得到表示系统可靠性风险为可接受决策级别的云模型,进而构成决策云集合,便可用于实际系统的可靠性级别多属性决策。
[Abstract]:In order to make the cloud model express and calculate the multi-attribute decision problem intuitively and conveniently, and adapt to the range data given by experts, the method of representing multi-attribute by attribute circle is modified. Then the characteristic parameters of cloud model are calculated by attribute circle, the definition, nature and drawing process of modified attribute circle are given, and how to calculate the characteristic parameters of cloud model representing a certain decision level by attribute circle, including defining decision system, is given. Attribute normalization, attribute circle features and properties, attribute circle area method, cloud model calculation based on attribute circle, and the calculation process and application scheme of cloud model are given through examples. According to the data processing and expert analysis, the cloud model which represents the reliability risk of the system as an acceptable decision level is calculated, and then the decision cloud set is formed, which can be used in the multi-attribute decision-making of the reliability level of the actual system.
