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.

System CM triggered by subsystem down.png

Reliability of all blocks follow Weibull distribution with Beta =1.5 and Eta=500 hours.

Block A and Block B are belong to maintenance group MG_AB.

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.
