Title: Minimum two lectures in a session in morning - afternoon mode
Post by: ngoctp29121982 on August 04, 2022, 03:15:16 PM
Hello Liviu!
Tell me how to quickly create a binding: Minimum two lectures in a session in morning - afternoon mode, when there are many teachers teaching 1 class in the afternoon: 3=1+1+1 or 1 class in the morning 4=1+1+1+1

Hello Livi!
In the morning - afternoon mode (A real day)
tell me how to create binding for all teachers: Minimum 2 periods/1 day (FET day). When there are many teachers. Example: Teacher A teaches only one class of 10A1: 4=1+1+1+1 and teacher B teaches only one class of 10A2: 5=1+1+1+1+1. Many teachers only teach 4 or 5 periods as above

Isn't it the constraint teacher(s) min hours per day?

I mean make a constraint of minimum morning =2 and afternoon =2 teaching hours for all teachers

Constraints: minimum number of lessons/session for all teachers

I don't understand why can't you use min 2 hours daily (half day).

For example: Teacher A teaches math, in the morning, class 12A1 is 4=2+1+1; Teacher B teaches Chemistry, in the afternoon, class 10A2 is 3=1+1+1; Teacher C teaches English, in the morning, class 12 A1 is 3=1+1+1 and in the afternoon class 10A3 is 3=1+1+1. Teacher D teaches, in the morning, class 12A4 is 3=1+1+1 and 12A5 is 3=1+1+1. More teachers like teacher
I want to make it binding for all teachers to teach at least 2 activities per day (half day)?

I still don't understand why you can't use teachers min 2 hours daily: All teachers (2) time constraints, the 7th entry.

But for 1+1+1 they can only be in one half day. So you must remove the min days between activities constraints, because otherwise FET cannot put all of them on the same day.

No, I mean minimum 2 hours per day Fet?
Can you show me how to get rid of the minimum Fet (real half day) days between constraints that act as 4=1+1+1+1

Min hours daily in FET Mornings-Afternoons mode is for FET days, min hours daily per real days is for real days!

In FET Mornings-Afternoons mode, all constraints are day/hours for FET days, and with real for real days. The only exception is min/max days between activities, where it is inverse.

You could add 2+2 (or 4 if on the same day), or go to all time constraints dialog, or go to min days between activities dialog.

OK, Thank You. Special cases 4=1+1+1+1 I assign that teacher to another subject also 4=1+1+1+1.......Works solution
