We agree with Eisinger and Rakowsky [16] that uncertainties need to be reflected in the analysis, but a clarification is required as to what this means. In our analysis, uncertainties refer to the occurrences of failure events and their consequences, and are not about vague (ambiguous) statements and the assessors’ doubt concerning what to do, as seem to a part of the Eisinger and Rakowsky [16] rationale for incorporating uncertainties.
