A prototype for integrating automatic fault tree/event tree/HAZOP analysis

Abstract The prototype of an integrated hazard analysis system IHAS has been developed in this study. Essentially any process can be analyzed with this software if the system topology is correctly supplied by user. Three widely accepted hazard assessment procedures, i.e. FTA, ETA and HAZOP, can be performed automatically. From the results obtained in practical applications, one can see that the quality of hazard analysis can be improved if IHAS is used as an aid to the human experts.
