Title: A difficult course
Post by: mesc on December 09, 2009, 03:53:54 PM
Hi everyone, my problem is that I have a course where I need to place a teacher with 14 hours in 5 days, only one group. I already tried to put an activity: 3 + 3 + 3 + 3 + 2  but FET doens´t permit that I dont know why, i am a really noob in this...
Or it would be correct to place 5 activities with different duration???...
please if someone has a solution for this thanks a lot!!!

Your method I think is correct. You can have any durations.

What errors are you getting? Please detail.

Day:            1     2      3       4       5
Durat.:         3     3      3       3       2

It´s like I can´t put 2 hours in a row and after that the other one... 2 + 1 but in the same day (if I left 3 duration for the day one in example), and I don´t have the continuos  hour check enabled. Then FET tells me that the activity is impossible at the time of make the timetable... I haven´t finish the schedule yet but for the moment the temporary solution has been this:

Practice  : 2 + 2 + 2 + 2 +2
And I added other signature almost the same:
Practice. : 1 + 1 + 1+ 1
Then I have 14 hours, same teacher, but 2 signature...

I am not sure I understand completely your post, but if you want to add 2+2+2+2+2+1+1+1+1 on a 5 days week, it is practically impossible. You need to add 2 split activities, like you said and like FET recommends, with 2+2+2+2+2 and 1+1+1+1.

A 3+3+3+3+2 activity is possible. compare attachment.

you must have done an (other) misstake. (Maybe the teacher has only 4 allowed working days, ...).

If you publish your sampleset we maybe can check it.

i can't see the 3+3+3+3+2 activities.

also your samplefile is impossible in group SECRETARIADO I, because you disallowed to many teacher hours.

compare attached minimilizied file. it is not solveable, because you need to allow also some late periods to some teachers.

to understand the problem better allow all 14:30 periods to teacher GILMA DE LA PAZ.

generate my simplified samplefile and you will see it is solveable. think yourself why it is no solveable - why it is not solveable if you disallow the periods.

just allowing that to your whole samplefile is not enough. if you want to solve your whole samplefile you must remove some constraints.

did you check the statistics? maybe you add to many activities? if not: you need to allow more teacher periods.
