云化S FT下的径集域与割集域的重构与研究
Reconstruction and research on size set domain and cut set domain in cloud SFT
摘要
Abstract
In order to overcome the problem of insufficient ability that the size set domain and cut set domain process the failure data with the discreteness and randomness and fuzzy(uncertainty)in original SFT,this paper used the combined me-thod of cloud model and the SFT to solve the problem.First it used cloud model cloud the SFT characteristic function,got a cloud characteristic function,and finally got the cloud size set domain and the cloud cut set domain.The cloud size set domain and the cloud cut set domain had no strict boundaries,the area distribution was represented by the cloud droplets.If cloud droplets said component/system failure probability represented by the cloud droplets was less than Pb ,the area of cloud drop-lets was cloud size set domain.On the other hand,the probability was greater than Pb ,the cloud droplets of area was cloud cut set domain.It analyzed the cloud size set domain and the cloud cut set domain of component X1 and system through the in-stance,which obtained the suitable factor change range for their work environment.Analysis process and the results show that cloud size set domain and the cloud cut set domain can overcome the uncertainty of the original failure data.关键词
