How to use splitted physical rooms

[Badam]

Hello Everyone,
In one of my buildings are some "special" rooms.
As an Example:
We have room "Japan" and room "Morocco" Both have a Capacity of 8(may vary)
These two rooms are next to each other. The wall who splits these rooms can be removed/retracted.
So if the wall retracts we have one room left, with an Capacity of 16(8+8). Let's say this room is called "Big_JapanMorocco"
Rooms:
- Japan -- C:8
- Morocco -- C:8
- Big_JapanMorocco -- C:16

My Question is how can is use this kind of room for building a timetable?
If room "Big_JapanMorocco" is in use, rooms "Japan" + "Morocco" are unavailable.
If room "Japan" OR "Morocco" is in use, the big one(Big_JapanMorocco) is unavailable.

I thought i could maybe use the "NotOverlapping" Constraint but i'm not sure if i'm correct with this.

I appreciate your help, thanks

The constraint activities not overlapping is for something else.

The only way I see it is to define the rooms Japan and Morocco, and use 2 small activities instead of the large one.

Maybe other users have some better ideas/tricks.

Are you using the official FET, or the mapr custom version? Did you obtain satisfying results so far?

Later edit: I thought some more. Maybe it is possible to add all the three rooms, and use some activities same starting time constraints, so that if an activity occupies a room at a time slot, the paired activities occupy the other rooms at the same time slot. Or it might be possible to derive a custom version for your case, with the exact constraint to not allow two rooms to have activities in the same slot.

Sorry i forgot to say, i'm using the custom mapr zt3. For other problems i have to use this version.
I didnt get any results with this so far.
In my room-list i have "Japan", "Morocco" and "BigJapanMorocco". I also thought that i could use activities to pair the rooms, but dont know exactly how i
should do that yet.

I think it is possible to derive you a custom version from the mapr zt3, to allow you to define exactly the rooms as you wish, but I would prefer to do this if mapr zt3 really works for you and you obtain useful results with it, so that the additional work is not in vain.

In my room-list i have "Japan", "Morocco" and "BigJapanMorocco". I also thought that i could use activities to pair the rooms, but dont know exactly how i
should do that yet.

Add some dummy activities, number of students = 8, preferred rooms = Japan, Morocco, and BigJapanMorocco, same starting time of these and the real activities.
