There is a case - lets say I have one production slot, limited by area. Some products operations occupies only 1/3 part of it, other 1/2 and others occupie whole production slot.

I want to use CRP to see overloads.

How can I reflect that in IFS?

I know that there's no perfect solution but what ideas I had was:

1 - Reflect production slots parts as a Work Centers and in routings create one or two or three parallel operations occuping different Work Centers

2 - Reflect production slots parts as a Work Centers Resources and in routings create one or two or three parallel operations occuping same Work Center, and then assign prefered resource on Shop Order Operations level.

Both solutions would require complicated SO's operations reporting (Client uses Shop Floor Workbench).
I'm laso aware about other impact. What I would like to have is best solution for that case.

All advice will be appreciate.
