طلب خاص الى السيد ليفيو

[Med BENNIOU]

HELLO MR LIVIU.
THANK YOU FOR RESPONDING TO MY MESSAGE IMMEDIATELY.
COULD YOU ADD A TIME CONSTRAINT THAT SET EXACTLY  NUMBER OF ACTIVITIES PER HOUR / HOURS.
EXAMPLE: 10 TEACHERS - EXACTLY - EVERY MORNING
THANKS FOR YOUR HELP

[Liviu Lalescu]

Hello, Mr. Med Benniou,

In FET official there are two constraints: activities min/max simultaneous in selected time slots. I believe you could use them both with the same value?

Also, I believe for exams Benahmed Abdelkrim started a topic here and a custom version: FET-nsrt: https://lalescu.ro/liviu/fet/forum/index.php?topic=4448.0 . Could you please also see that topic there? Maybe it corresponds to your case.

[Med BENNIOU]

Thanks you Mr Liviu.

[Liviu Lalescu]

You are welcome!

[Liviu Lalescu]

Please tell me, did you solve it using FET-official or FET-nsrt, or you need the constraint activities min simultaneous in selected time slots added into FET-MA? (because max is available in FET-MA). But I cannot promise I'll make it soon.

Or can you use the official FET or FET-nsrt?

[Med BENNIOU]

HELLEO,Mr Liviu
We need   the constraint activities min simultaneous in selected time slots added into FET-MA.
thank you for help

[Liviu Lalescu]

OK, I understood. It will be on the TODO list.

You are welcome! 

[Med BENNIOU]

Thank you very much.

[Liviu Lalescu]

I added the constraints activities min simultaneous in selected time slots and occupy min time slots from selection. The new version is not ready, I did not test, and I plan to add some more suggested constraints. But if you are in a hurry to obtain a timetable, I could give you a test version, because the new constraints seem to work.

Please let me know if you meet any problem or if it works.

HELLO,Mr LIVIU
I WILL REPLY YOU EARLY.
THANK YOU.

[Med BENNIOU]

HELLO Mr LIVIU.
For my first situation, the constraint "min simultaneous activities ...." is very satisfactory. Indeed, the situation is:
during the same day (morning + evening) we want the number of teachers to be slightly different (7-10) (6-9) (9-9) .... what the added constraint .
for another situation, I will let you know as soon as possible.thank you again.

[Liviu Lalescu]

OK, that is great!

[Med BENNIOU]

HELLO, Mr Liviu
THE "MIN SIMULTANEOUS activities ....."  TIME CONSTRAINT .... SOLVED MY 2nd PROBLEM.
Thank you for your generosity.
