摘要
专家信息的相关性会对专家信息融合的结果产生影响。提出基于主成分分析的相关专家信息融合方法。首先给出可靠性试验评定中专家信息的提取融合流程,然后采用主成分分析方法对专家信息的相关系数矩阵进行分析,接着利用分析的结果对专家信息转化成的概率分布进行融合,最后给出了一个应用实例。
The dependence of expert opinions often results in an unrealistic aggregation. This paper presents a method for aggregating the expert opinions based on the principal components analysis. First, we present a procedure for eliciting and aggregating the expert opinions. Second,we compute the priority of each expert opinion using the principal components analysis. Then,we aggregate the expert opinions＇ probability distributions using the priority of each expert opinion. Finally, a numerical example is given to apply the method.
