Hello, I'm starting to use FET and I have this problem. A course has some particular features. In this course there are 24 classes of students divided into three groups of 8 classes. The 24 classes share all spaces. However, each group of 8 classes has its own group of teachers. The biggest difficulty I found, is that each group of 8 classes, despite using the same spaces, have different schedules that overlap. Classes for the first group start at 7 am and go until 5 pm. For the second group, they start at 8 am and go until 6 pm. For third group, they start at 9 am and go until 7 pm. The Classes are one hour long with a twenty-minute break.Each group has a 90-minute lunch break starting at different times.
How to work with periods per day starting at different times?
Hello, Marcio,
Isn't this as simple as adding constraints students set not available?
How many rooms do you have in your school ?
For each group there are 4 classrooms available. However, we have classes in the gym and there is only 1. We have two dojos for the 3 groups.
Thanks Liviu for answering me.
So, initially, it generated the timetables individually for each group. For example, group 1 used the gym at a different time interval than the other groups. I did the same for the other two groups. But managing shared spaces between groups "manually" generates a lot of work.
These are the periods per day that each group has:
7h30 - 8h30
8h50 - 9h50 8h30 - 9h30
10h10 - 11h10 9h50 - 10h50 9h30 - 10h30
11h10 - 12h40 11h10 - 12h10 10h50 - 11h50
12h40 - 13h40 12h10 - 13h40 12h10 - 13h10
14h - 15h 13h40 - 14h40 13h10 - 14h40
15h20 - 16h20 15h - 16h 14h40 - 15h40
16h40 - 17h40 16h20 - 17h20 16h - 17h
17h40 - 18h40 17h20 - 18h20
18h40 - 19h40
Oh, now I see the problem.
I would suggest you to consider a FET hour = real 10 minutes. An activity will have duration 6, break will have duration 2, and lunch will have duration 9. FET hours will be:
7:30,
7:40,
7:50,
8:00,
8:10,
8:20,
8:30,
8:40,
...,
19:30.
So, 12*6+1=73 FET hours per day, if I calculated correctly.
You will add then not available constraints for students.
I don't understand the thing with dojos.
You can add home rooms for each students set with 100% and preferred rooms for subject sport with 100% to the gym.
Please let me know.
