GB/T 37080-2018 in English

This standard provides a method for analyzing the causes and consequences of events in complex systems through event tree analysis (ETA). It outlines procedures for identifying initiating events, modeling the progression of events, and evaluating potential outcomes. The document includes guidelines for constructing event trees, defining logical relationships between events, and quantifying probabilities associated with different scenarios. It also addresses the application of ETA in various industries and contexts, ensuring consistency and reliability in the analysis process. The standard supports the use of ETA as a tool for risk assessment, system safety evaluation, and decision-making in engineering and operational environments. It covers key aspects such as data collection, model development, and result interpretation, facilitating a structured approach to understanding event sequences and their impacts.
