This is the default Cuttoff settings for Common Cause
It is noted that the term refinement does not really apply to Common Cause in eXpress as all tests that fail point to a single failure. The testing Algorithm is the same as refinement in Multiple fault isolation but the results are termed Common Cause not refinement.
Therefore no Refinement Cutoff exists for Common Cause
Possible Cutoff Variations: (Same as for Multiple fault as repeated here)
To setup a new Cutoff variation select the + Button on the upper right.
To delete a Cutoff use the - Button on the upper rtight
Most used besides default are the Cost and Time cutoffs. These provide the analyst with the means to limit isolation to Cost and Time Requirements Parameters.
