(More) Complex Parallel system & Repairs

[Jennifer.Bell]

I have a parallel redundancy situation with, say, 3 branches, each and in each branch there are 2 items in series.

The first item in the branch (1) has a different repair group than the second (2). If 1 fails, the system does not fail but a repair is triggered for 1 and an inspection & repair is triggered for 2. And vice versa. So when an item in the branch fails, the whole branch is reset to new (even though the system is not down). Also, repair group 1 (only 1, not 2) has a long logistic delay time.

My question is this - if during the logistic delay time for repair on item 1, item 2 fails, will it issue a (successful) call for repair by repair group 2? For item 2, the inspection is carried out by repair group 1. In a more general sense, what happens to components who are in series configuration with a failed item in a branch of a parallel system?

Thanks for your help

I don't think I understand the specific case, maybe your best bet is to call support. I am not sure how these 2 crews (that is what you are calling a repair group, right?) are associated with the 2 blocks.

Components who are in series configuration with a failed item in a branch of a parallel system continue to operate. Therefore, if item 1 has failed, it is possible that item 2 will fail as well. If item 2 fails, it will call the first crew in its list. If that crew is tied up, it will call the next crew in the list. If all crews are tied up, it will wait for repair until a crew is available.

Hope this helps but please give support a call if there is still confusion.

Thanks - that actually does answer my question.
