Hi IRStuff.
Thanks for that, they are fully redundant but have different MTBF's as the each system is composed of different parts although do the same thing, should one go down.

Hi.
I am new to this and have to work out a systems reliability that has 4 components all in parallel. The MTBF's I have calculated for each system using the failure rates and MTBF's. These are A = 1433 hours, B = 1443 hours, C =1342 hours and D = 1232 hours. To calculate the systems overall...
