Suggestion

[tizaya17]

Hello Mr Liviu
First of all, we thank you for your wonderful application , which has been widely distributed and the proof of this is its adoption by the Moroccan Ministry of Education.
As a contribution to its development and as one of those who have gained considerable experience in working with it, I suggest you add the following constraint:
A favorite room for a teacher during specific time periods
This constraint is very important and we need a lot to install a teacher in the same room only during certain days
Please accept our sincere thanks and appreciation



تحية و بعد
أولا نشكرك على برنامجك الرائع و الذي لقي انتشارا واسعا ولا أدل على ذلك اعتماده من طرف وزارة التربية و التعليم المغربية .
وفي اطار المساهمة في تطويره و باعتباري واحدا ممن اكتسب تجربة كبيرة في العمل به , أقترح عليكم اضافة القيد التالي :
قاعة مفضلة لأستاذ خلال فترات زمنية محددة
هذا القيد نرى أنه بالغ الأهمية و نحتاجه كثيرا لتثبيث أستاذ في نفس القاعة خلال أيام معينة فقط
وتقبلوا منا خالص الشكر و التقدير

Hello and welcome, Mr. tizaya17,

So you choose a teacher and a room and some time slots in this constraint? Always with 100% weight? Stronger than preferred room(s) and home room(s) for this activity?

Could you show me an example of such a timetable?

It is very unclear to me how this constraint could be useful. To make sure I understand correctly, could you tell me why you need such a situation?

Can't you use constraint activities occupy max 1 different rooms? (but this will set the teacher in the same room all the time.)

Or maybe you could use building changes constraints?

The following example:
We have assigned Room 1 to Professors A and B. (permutation) Because we want to stop the study on Saturday evening (for example) must be assigned another room (2) to Professor B. After production, we find that the quotas of Professor B are distributed between rooms 1 and 2 (normal). How do we get Professor B to work in Room 1 all week and not change the room until Saturday? I have created a video that addresses this problem (link below) but would prefer it to be programmed as a constraint

Can't you add a constraint Room 2 not available in all the days but Saturday? Or add a dummy room DR in the preferred rooms of Professor B, and DR is not available all week without Saturday?
