How to enforce a full free period throughout the day?

[erick nimtz]

Hello everyone, hope you all are doing well.

I have this case where local labor laws enforce the school to not schedule classes for a teacher that span throughout 3 periods of the day.

I mean, if a teacher lectures a single class in the morning and a single class in the afternoon, she/he can not lecture any other class at the night period (At least not at the same school. One can decide, at you own free will, to teach on other schools).

I hope the diagram I attached helps to understand this situation.

My question is: how can we enforce these allowed cases to happen on fet programming?

My best wishes for you all.

Hello, thank you!

This might work: add n_days_per_week dummy activities with duration 6 for each teacher, preferred starting times as needed. Unfortunately, I see that your night is shorter. But maybe you could think of some tricks, like adding 1 extra hour at the end and disallowing for the real activities.

Or a customization might be possible.
