Hello all,
First of all i wanna thank you for the great respone times in my last posts.
I'm using "fet-5.22.0-mapr-asa8-zt3"
I'm sorry that i cant attach my *.fet file but its private, and it would take to long for editing it.

If i want use a constraint which puts two activities into the same room, i can use the constraint occupyMaxDifferentRooms.
But if i'm doing that, fet can't find a solution for me.
My idea is that it is because i have fet-rooms and fet-subjects. Maybe fet is trying to allocate two activities into the same fet-room, what is surely impossible.
The attached file, "SameRoom.xml", shows the constraint with all associated activities.
The two Activities in the Constraint (1913, 1739) are each one activity with a real subject. this realSubject-activity has a SameStarting constraint with its FSubject. And only these FSubjects are allocated to real rooms if i understood it correctely.(Only these have a preferredRoom constraint)
i know, its hard to understand, but i hope you know what i mean. Does the OccupyMaxDifferentRooms constraint works with the custom version of fet?
If needed i can send you the *.fet file private.

Thanks for your help and your suggestions

It seems that it work, great.
Thank you a lot

[FSubj_TW-5311sp_mt]

Hello all,
i have the following problem:
i'll attach all necessary images.
i'm using Version "fet-5.22.0-mapr-asa8-zt3"

I have 2 subjects, FSubj_TW-5311sp_mt and FSubj_TW-5202sp_wem
Each of these Subjects have a SubjectPreferredRooms Constraint. It depends on the class size which rooms are in this constraint.
In this case both have the same room(and others) in its constraint, the room is called RoomROK-E5A.
If i generate a timetable, both Subjects will be in the same Timeslot and in the same room, so they're overlapping. If i look at the other preferred_rooms which are in the constraint too, they are empty at this Timeslot. So there would be enough space to spread the Subjects into its own rooms.
I know there is the "NotOverlapping" Constraint but i cant use it here because i dont know which preferred_room fet is going to choose
Is there a trick for this custom version, or am i missing a constraint?
Thanks for your suggestions

Okay thank you for your suggestion, i'll try it out soon

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.

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

I'm still working on a solution for me, but your little file has helped me, thanks for that.

it's the case that i only know which course the student would like to visit, the classsize is Unknown.
For every course are a few teachers aviable. Different Teachers, or the same teacher more often but to different times(slots).

The students can register for every subject they would like to visit. When everyone registered their wishes, i should be able to generate a timetable. So i dont know how many students visit each subject yet.

I'll try to show you my input excel data.
I attached the photos of my excel sheet.
I have:
-  [img class_list.PNG] -- "Class_type" and "Class". "Class_type" is the Subject. If this Subject will be teached more often than once, the "Class" consists of" class_type" + the number.
    There is also our "speaker_Mail" which are the teachers. The Preferred Room is a real room where this subject should be in. Our Preferred Location is same as Preferred Building.

- [img participants.PNG] -- Here is every person listed, even the teachers. If a Participant is a teacher, he will be marked as soone with"teacher_studentName"(visible at "class_list.PNG")

- [img class_visits.PNG] -- This is our List where Participants registred into the subjects they would like to have. Again, "Class_type" is the real Subject, "Class" only an instance of it.

I've made a C# program which generates a *.fet file with all the participants as Students, all Speakermail's as Teacher, all rooms and locationas rooms and buildings.
And there is what im struggeling with, i dont know what i have to add that fet can make a timetable with this data input.

I hope you understand it, if not im here to help you as far as possible.
Thank you for your Answer

Hello all,
I'm using fet-mapr-asa-zt3 and working since a few days on a solution for my problem, i hope you can help me with that:
I have to generate a timetable for some participants which visitting different courses(subjects) by different teachers.
My problem is to understand the function of the fet-rooms, which i schould use in this custom version.
Another problem is that a student also can be a teacher. So they cannot be a student and a teacher at the same time.
A simple example what my input looks like:
Students - years - "Every single Student"
Teacher - sp(speaker)_"name of the student"
Subjects - The different Subjects
Buildings - 3 Buildings
Rooms - Rooms in the 3 Buildings

I want to know how to use Activity tags, and the Fet-rooms

I'm excited for your suggestions, thanks
