You may start performing the maintainability analysis only after the Preliminary Steps are done.

 

The primary goal of Maintainability Analysis in RAM Commander is MTTR and Mct(max) calculation. Both parameters are calculated based on Mct of corresponding tree items. For Mct calculation of each item you should define a list of corrective maintenance (e.g. replacement) procedure tasks with their times.

When these procedures are defined, you may activate the calculation to get MTTR and Mct(max) values for all the system and different sub-systems.

 

The paragraphs below explain the analysis procedure.

 

The calculated MTTR values may be used in other analyses like Reliability Block Diagrams , Fault Tree Analysis , Markov Analysis etc.
