The Design and Implementation of the Computer Aided Fault Tree Analysis System Based on UML and J2EE Technology

Fault Tree Analysis (FTA) is a hotspot both in academic field and in modern industry. The FTA method is a means that evaluates the system reliability and safeties, using to predict and examine the faults, analyzing the weak link of system, guiding to circulate and maintain, and the optimization design of system. Along with the technical exaltation of the computer science, the computer aided technology has already become an important method to the fault tree analysis. In order to explore a effective FTA model for modern industry domain in China, this paper studied FTA and its development, analyzed the problems existed in FTA as well as the deficiency in implementing FTA, and proposed an integrated FTA system - Computer Aided FTA System (CAFTA). Finally, this paper expounded the process of the system´s designing and implementing based on UML and J2EE technology.
