CM triggered by subsystem down
Purposes
The purposes of this example is to illustrate how to model the case when CM is triggered by failure of subsystem.
Description
Three devices A, B and C are in parallel. A and B form a subsystem. Only both A and B fail (subsystem fails), then start to repair A and B. The repair of C is depend on its failure. When C fails, then start to repair C.
BlockSim Solution
The BlockSim modeling of this system is shown in Figure below.
Reliability of all blocks follow Weibull distribution with Beta =1.5 and Eta=500 hours.
CM of Block A and B are set to "When found failed during an inspection". The CM duration is 120 hour and upon repair, it is as good as new.
