Compute reliability of series/parallel systems. Series: system works only when all components work; Parallel: system works when at least one component works.
Reliability of each component (0–1)
MTBF = Mean Time Between Failures, MTTR = Mean Time To Repair, Availability A = MTBF/(MTBF+MTTR). Enter number of failures and total operating time to auto-compute.
Or: compute from operating data (optional)
Simplified fault tree analysis: the top event is formed by combining basic events through an OR/AND gate. Enter the occurrence probability of each basic event.
Basic events (name + occurrence probability)
