Step 6 – Calculate cognitive failure probability (CFP): The CFP specifies human failure probability for each cognitive failure type in order to calculate HEP value. Once the nominal cognitive failure probability (CFP 0) has been nominated for each sub-task, the CFP value (HEP) can be calculated respectively.The CFP 0, which was mainly gathered from a wide range of sources, denotes the
