New condition or solution to this problem

[henriquebelo]

Hi Liviu,

In order to free the students' workload, on the days when they have more teaching hours, we need and avoid that two theoretical disciplines stay on those days at the same time.

Attached is an example of a simulation in subjects that could not be on the same day, where there are more teaching hours.

The subjects that could not be on the same day are highlighted, but can be one or the other, and not both on the same day.

How can we avoid this problem?

New condition? Or work with tags, but I can't find practical solution.

Thanks
Henrique Belo

Hello, Henrique,

I think that there is no need for a new constraint and that you can use constraint students (set) activity tag max hours daily.
