Failure nodes and Logical nodes
How are failure nodes represented in risk trees?
How are failure nodes represented in risk trees?
Failure nodes are represented by circles or rectangles depending on whether they are basic or decomposed further into causes
Explain the difference between AND and OR nodes in risk trees.
Explain the difference between AND and OR nodes in risk trees.
In the case of an AND node, the causing child nodes must all occur for the parent node to possibly occur as a consequence. In the case of an OR node, only one of the causing child nodes needs to occur for the parent node to possibly occur as a consequence.
