区间三角模糊多态贝叶斯网络可靠性分析方法研究
System Based on Interval Triangular Fuzzy Bayesian Networks Research on Reliability of Multi-state
摘要
Abstract
In order to overcome the shortages of dealing with fuzzy information in traditional sys-tem reliability analysis methods,this paper proposed a new method of reliability analysis method based on interval triangular fuzzy multi-state Bayesian network.An interval triangular fuzzy subset was built to describe fault rate of root nodes.A model of the interval triangular fuzzy multi-states Bayesian net-works was built based on the interval triangular fuzzy subset.The calculation methods of leaf node fault probability were proposed,and the deblured posterior probability was researched by the reliabili-ty analysis algorithms of interval triangular fuzzy multi-state Bayesian network.At last,the method was applied in the reliability analysis of tower crane overturning accident,which shows that the pro-posed method is feasibility.关键词
