minimum of 2 lessons in every slot

[sasbland]

Hello, we need to have at least 2 cover teachers on standby in every hr of the week. So I created activities with subject cover with no students, no room for all teachers. How can I ensure that fet put at least 2 cover lessons in every slot of the timetable?

Do I have to use activity occupies min time slot and click one hour by one hour, that is 40 hrs. Is there an easier way?

Many thanks

Hello!

Very easy: A constraint activities min simultaneous in selected time slots.

Or the inverse: select all activities, max simultaneous = n_teachers-2, and no need to use dummy activities for cover.

Thank you very much. I'll try both.
