摘要
影响图(本文称为决策关联图①)是概率模型和决策分析模型的一种网络表征。本文探讨了如何用一类决策关联图(即关联图)来表征单个或群决策者关于不确定变量集所拥有的信息以及如何对这些信息进行概率评估。特别地,通过一数字例子分析。我们给出了关联图的一种特殊评估方法──迭代评估法。最后,结合这方法,我们提出了评估关联图的一个新的一般性方法。它推广了关联图的可应用性。
An influence diagram(here.it is named as decision relevance diagram) is a schematic representation for probabilistic and decision analysis models.This paper explores how to use a type of decision relevance diagrams to capture the diverse information possessed by an individual or a group about any uncertain event and how to assess the information.Particularly,by a numerical example analysis,we give a special assessment method of relevance diagrams-named as the iterative assessment method,Finally.combining with the method,we provide a new general assessment method of relevance diagrams. It extends the usefulness of relevance diagrams.
