【摘要】:為了使云模型能直觀方便地表示以及計算多屬性決策問題,并且適應(yīng)專家給出的范圍數(shù)據(jù),對提出的屬性圓表示多屬性的方法進(jìn)行了改造,從而通過屬性圓來計算云模型的特征參數(shù);給出了改造后屬性圓的定義、性質(zhì)和繪制過程,以及如何通過屬性圓計算表示某決策級別的云模型特征參數(shù),包括:定義決策系統(tǒng)、屬性歸一化、屬性圓特征及性質(zhì)、屬性圓面積求法、基于屬性圓的云模型計算;通過實例給出了云模型的計算過程和應(yīng)用方案。根據(jù)數(shù)據(jù)處理和專家分析,計算得到表示系統(tǒng)可靠性風(fēng)險為可接受決策級別的云模型,進(jìn)而構(gòu)成決策云集合,便可用于實際系統(tǒng)的可靠性級別多屬性決策。
[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.
