USER’S EFFECTUSER’S EFFECT
36/50
User effect is originated by:
A) Nodalization development;B) Interpreting the supplied (or the available) information, usually
incomplete;C) Accepting the steady state performance of the nodalization;D) Interpreting transient results, planning and performing sensitivity studies,
modifying the nodalisation and finally achieving “a reference” or “an acceptable” solution.
• Items A) and B) can be connected with the ‘global acceptabilityfactor for the nodalization development’, QA;
•The ‘global acceptability factor for the nodalization qualification at steady state level’, QB, deals with item C);
•The activities at item D) can be summarized trough the single average accuracy values (AA, and particularly AAP-1) and by the global average accuracy value (AATOT).
