This study focuses on a novel approach which automatically proves the correctness and completeness of fault trees based on a formal model by model checking. This study represents that the model checking technique is useful when validating the correctness of informal safety analysis such as FTA. The benefits of this study are that it provides the probability of formally validating FTA by proving correctness...
The main purpose of this study was to develop a computer automated tool for fault tree analysis (FTA) in order to minimize the flaws of manual FTA. The automated FTA system developed in this study consists of two steps: 1) automatic fault tree conversion from a digraph, and 2) calculation of the probability of the occurrence of the top event and finding a minimal cut set of the top event. For the...
