Loss Scenario Table¶
This is the table to analyze the HCF (Hazard Causal Factor) related to a specific UCA. The Loss Scenario Table is created under the project.
Creating the Loss Scenario Table¶
To create an Loss Scenario table, specify the analysis target UCA.
When the menu [Diagram] - [STAMP/STPA] - [Loss Scenario Table] is selected, or the menu [STPA Analysis Procedure] - [STEP 4 Identify Loss Scenario] - [Loss Scenario] is double-clicked, specify the UCA in the Select UCA dialog.
On the left of the UCA which created the Loss Scenario Table, the circle symbol is displayed.
Hint Word Set¶
Select the Hint Word Set from the drop-down list of the Hint Word Set.
The specified Hint Word Set will be reflected in all the HCF Tables corresponding to the same control loop. Hint Words in the HCF Table whose Hint Word Set has been changed will be cleared.
