Custom FET MA (mornings/afternoons or Morocco/Algeria)

fourat · July 19, 2020, 09:53:11 AM

precisely the morning an the afternoon of the same real day

Benahmed Abdelkrim · July 19, 2020, 11:29:40 AM

I think it is a bad idea, unless the constraint considers a real day, not half-days. Because the gaps between morning and afternoon will increase which will make the timetables very bad!

الفجوات بين الحصة الصباحية و المسائية لا تعتبر سيئة وفقا لمعايير وزارة التربية والتعليم التونسية

Liviu Lalescu · July 19, 2020, 12:34:12 PM

OK, I will consider this constraint. Not sure when I'll be able to do it.

Big thanks

Liviu Lalescu · July 19, 2020, 05:01:02 PM

fourat: Please send me a test file, which should not take too long (a few minutes), and tell me which constraints resting time to add. I did not begin work yet, but I might tomorrow.

fourat · July 19, 2020, 05:21:58 PM

i'll send you a sample of a large file

fourat · July 19, 2020, 06:23:57 PM

This is the sample file
hours 1,2,3,4,5 at the morning are the real hours 08:00-09:00 ,09:00-10:00 ,10:00-11:00,11:00-12:00 and 12:00-13:00
in the afternoon they are the real hours 13:00-14:00,14:00-15:00,15:00-16:00 ,16:00-17:00 17:00-18:00
for example When a teacher or a student ends at the last hour of the morning (fifth hor) he must restart as soon as possible in the 3rd hour of the morning ( resting time 2 hours at least)

Benahmed Abdelkrim · July 19, 2020, 07:54:24 PM

Well, this limitation will help in solving this problem. Sorry I did not understand at first time the feasibility of adding this new constraint. Now I understand well 🙂

على ما يبدو في الشقيقتين المغرب والجزائر تكون الحصة الصباحية من الثامنة إلي منتصف النهار و المسائية من الرابعة عشرة إلى الثامنة عشر
في حين في تونس بإمكان المؤسسات العمل خمسة ساعات صاباحا و أربع أو خمسة ساعات مساءا
مع مراعاة الحد الأدنى لساعتين كراحة فاصلة للتلاميذ و الأساتذة

نعم بسبب هذا الاختلاف لم أفهم جيدا الجدوى من إضافة القيد. فعندنا الأمر مختلف. نعم هذا المقترح يصلح في حل هذه المشكلة. مع التوفيق

I did it: https://lalescu.ro/liviu/fet/download/custom/ma/test/ (snapshot. The new final version will be put soon - probably in 1 day).

Please let me know if it works OK.

Hello thank you very much
i tested with the sample file: no problem detected with single generations and also with multi generation ( 100 researches delayed 202 seconds)
concerning the original I am in the process of editing; it is a very big file for witch I am looking for an efficient automatic editing method

On Tuesday, 21 July 2020, I released the new version FET-5.27.3-MA8, with the suggestion by fourat: constraint teacher(s)/students (set) min resting hours between morning and afternoon (of the same real day).

Thank you! to fourat for the suggestion, to bachiri401 for testing and to Benahmed Abdelkrim for his dedication on the Arabic translation and bug report.
