In order to address safety risks in prefabricated building construction,the Fault Tree Analysis(FTA)method is adopt-ed to identify hazards in the process of prefabricated building construction.The Fuzzy Set Theory and Binary Decision Diagram(BDD)structure are used to calculate the accident rate of construction safety risks and the importance of each basic event.By traversing the BDD structure,management personnel can effectively control the weak links and key influencing factors in prefab-ricated building construction,and achieve qualitative and quantitative analysis of safety risks.Empirical evidence shows that the introduction of the BDD evaluation method and fuzzy set theory can better deal with the fuzziness and randomness of safety risks in prefabricated building construction,and use program programming to quickly obtain the key factors of safety in prefabricated building construction,improving analysis efficiency.
