Each candidate to MMEL list affects system safety if the candidate is inoperative.

RAM Commander may help in candidate element failure safety effect evaluation and prove this candidate element inclusion into MMEL list.

RAM Commander has all the necessary data for such a quantitative analysis and may generate report to support the decision making about each candidate inclusion into the MMEL list.

 

See the decision making/algorithm explanation in the MMEL Module Quantitative Analysis Algorithm paragraph.

See the decision making quantitative report example in the To activate quantitative analysis paragraph.

 

The results quantitative analysis results for each element should be manually compared to the safety requirements (maximal allowed failure probability per each severity classification) and expert takes a decision about element inclusion into MMEL. If the decision is positive, the element should be selected as "Candidate" and the 2nd analysis step (5-column report) should be performed.
