händelseträdsanalys
Händelseträdsanalys, often translated as Event Tree Analysis (ETA), is a graphical, inductive method used to analyze the potential consequences of an initiating event. It starts with a specific event, such as equipment failure or human error, and then systematically traces the possible sequences of subsequent events that could occur. These subsequent events are typically safety systems or barriers that are intended to prevent or mitigate the consequences of the initial event.
The analysis branches out at each point where a safety system can either succeed or fail. This
Händelseträdsanalys is valuable for identifying critical safety systems, understanding failure modes, and quantifying risks. It is
