A Proposal for an Effective Fault Tree Diagram Layout

Fault Trees (FTs) have proven particularly successful in engineering disciplines to identify and quantify risks for assessment.Due to the only short descriptions, FTs are mainly a visual language and transcends national and language boundaries.To further reduce the risk of misunderstandings with FTs, we have tightened the layout guidelines and adjusted the FT elements accordingly.During our research, we kept the three aspects of efficiency, applicability, and functionality in mind, allowing FTs to communicate as correctly, quickly, and easily as possible to make our societies even safer.
