The research and design of visual fault tree modeling analysis

According to the situation that creating fault tree manually is inefficient, error-prone, existing software of visual fault tree modeling is not perfect, not easy to transplant, research visual modeling and analysis of the fault tree. First, this paper discusses the visual building method combines dynamic contribution with stratified achievements, fault event editing functions, separation of fault tree with failure information method, then discusses the fault qualitative analysis in visual modeling process, final design the visual fault tree modeling platform, realize the rapid modeling and visual analysis of the fault tree, and presents an application examples to illustrate. The actual instructions that the system can meet the needs of visual fault tree modeling.
