You can use the new failure modes and reliability analysis (FMRA) to integrate statistical reliability analysis calculations into your FMEA activities. Specifically, this view can be used to: 1) Display all of the FMEA records that could have an impact on system reliability in a single hierarchical tree. Assuming a simple series reliability-wise configuration, this includes the occurrence of any failure mode that prevents the item from performing an intended function or the failure of any lower-level sub-items. 2) View and set the reliability characteristics for any item, function, failure or cause defined for the system. 3) Calculate the "probabilities of failure" values required for a quantitative criticality analysis. 4)Use the occurrence ratings that have been defined in the FMEA to generate a preliminary baseline reliability estimate for the system that can be improved later when actual failure data becomes available. 5)Integrate with BlockSim’s reliability block diagrams (RBDs) or fault trees, which facilitate more realistic system modeling (e.g., consider redundancy, common cause failures, etc.). | |||
