This paper describes a method of converting block diagrams into fault tree forms for computer-aided fault tree analysis (FTA). This conversion method aims at achieving high quality and efficiency of FTA for reliability design in manufacturing industry. The method has been implemented as one of the capabilities of computer-aided FTA software "FTAid", which has been developed in a case study to realize a practical software product for the corporate business based on academic research products. The proposed method enables to construct fault tree (FT) automatically from a block diagram of the system to be analyzed. Moreover, the resulted FT includes the additional information to be utilized by the other capabilities of FTAid for supporting FTA. Therefore, the proposed method can contribute to achieving high quality and efficiency of FTA.
