QuoteI know vacation is about to start, but I have a question for when you all come back I don't get any timetable after more than an hour od generating. I don't get an error message, I just don't get a timetable. Is there a way that I can detect where the problem is?simultaneous activities or teachers constraints or rooms constraints? maybe changing just one thing would solve the problem, but how can I know what thing I must change? Thanks
Quoteok, thanks and have a nice vacation
QuoteOk, I've solved that timetable, but I have another problem now. I have some constraints for ALL teachers like max 2 afternoons (7th hour) per week, or max 6 gaps per week, or Min 2 hours per day. Well, i got like 3 or 4 timetables with one day and zero activities, which is illegal in our school system (min hours daily is 2). This is normal for teachers who only work part time, because I have set them to work only 3 days a week (according to the law), but the teachers who work full time MUST work every day (at least two hours). How can I tell FET to not give any free day to any teacher (apart from those who work part time, because I have specific constraints for those).
Quotedo you two mean that I add a 5 hour activity for EVERY teacher in the school? for the 50 of them? Because I have tried to add an activity 5 hours with ALL teachers who work full time and I got no timetables. It gets stuck at 251 activities, and I have 740. Please give me more details as to what do you two mean.
QuoteI'm not sure if I understand this about setting last hour not available. The law here is:Students have 30 hours a week (no more, no less). Students are not allowed free periods. Students are not allowed 2 classes of the same subject in one day.teachers are no allowed any free day.teachers must do a minimum of 2 hours a dayteachers must do a maximum of 6 hours a dayteachers are allowed gaps, in fact I need gaps, because I set surveillance in those gaps.All the above is the law, so I don't know how to tell FET all this. it was easy last year because I didn't get any free day for any teacher, but this year I get 2 or 3 teachers with a free day.Only part time teachers who do halp of the hours are allowed 2 free days.If I set an activity with 5 classes and all the teachers there the teachers who work part time will get horrible or impossible timetables.We allow the teachers to set a maximum of 4 X in their timetable, where they want to have free time. Some of them prefer free 1st periods, some others prefer free last periods. I don't know if this is enough info for you. But please, respect your holidays and do not answer until you come back, I'm so sorry
QuoteOK, I understand what you say, I think. The problem I see is that if I block those 5 activities at, lets say, an invented 8th hour for every day, the teachers who work part time (only 3 days a week) will give conflict, so I should leave them out of this activity.Besides, if I put all teachers in that activity and make them "work" everyday at 8th hour, the timetables will be weird, because the 6 gaps max a week will be interfered with by this 8th hour. I don't know if you understand what I'm trying to say, hehehe, it sounds very cryptic now that I read it.
