Hi there,
I got next situation, and I need some help to introduce the data in FET.
A 10 weeks period, some of the activities have one sessions of 4 hours a week, and others have sessions of 6 hours a day, and all of the activities are regular, I mean the timetable is repeated every week, except one that is like this:
Week01: Session 4 hours
Week02: Session 6 hours
Week03: No Session
Week04: Session 6 hours
Week05: No Session
Week06: Session 4 hours
Week07: Session 6 hours
Week08: Session 4 hours
Week09: No Session
Week10: Session 6 hours
An option that I have is to name activities of 6 hours: AC06, and those of 4 hours AC04, if that helps.
:o
In your sample you wrote:
Week 02: Session 6 hours
Week 03: No Session
Question:
Is it clear that Week 2 has 6 and week 3 has no session? (in that case i know a solution)
or might it swap, so week 2 has no and week 3 has 6 session? (in that case i don't know a solution.)
i just wonder a bit that a 10 weeks period is needed.
can't you simplify it?
Maybe just always have 4 hours?
or maybe half of the weeks 6 hours and the other half 0? or something like that, so you able to reduce the number of weeks?
oh.. i just see maybe i missunderstood. can you please tell use the number of days you set in the fet->data->day&hours->days per week.
Thanks for answering Volker,
well, the situation has become a little more difficult, the way it was on the firs post was O.K. since now, so in that case I was clear the way it was, and still is.
Now, some info, for us each hour at FET is really a 15 minutes period, so I will call them periods from now on.
Second, the activities are for a group of 80 students, all of them going together to the 4 periods sessions, but separated in three gruops for the 6 periods sessions, so we have:
Big Group = 80 students
Sub Group A = 30 students
Sub Group B = 30 students
Sub Group C = 20 students
the 6 periods sessions are for activities:
Act1 - Group A
Act2 - Group B
Act3 - Group C
This activities will be the same day and can not overlap
Week01: 1 Session 4 periods
Week02: 3 Sessions 6 periods (1 for each group)
Week03: No Session
Week04: 3 Sessions 6 periods (1 for each group)
Week05: No Session
Week06: 1Session 4 periods
Week07: 3 Sessions 6 periods (1 for each group)
Week08: 1 Session 4 periods
Week09: No Session
Week10: 3 Sessions 6 periods (1 for each group)
What a big mess, no?
5 days, Monday to Friday.
Is this situation just for a singel subject or maybe similar with 2 other one?
so maybe:
week 1: 4 periods subject A, 6 periods subject B, 0 period Subject C
week 2: 6 periods subject A, 0 periods subject B, 4 periods Subject C
week 3: 0 periods subject A, 4 periods subject B, 6 periods subject C
if it is that way, you should think about using a workaround like with forthnightly activities, so you just do it with 3 activities.
check this:
http://www.timetabling.de/manual/FET-manual.en.html#id_36
i forgot to say:
you can maybe also use one of that workarounds if you have similar problem to differnet groups.
so:
week 1: 4 periods group A, 6 periods group B, 0 period group C
week 2: 6 periods group A, 0 periods group B, 4 periods group C
week 3: 0 periods group A, 4 periods group B, 6 periods group C
Sorry, I have to keep going with this, and sorry again because all the situation has change again (I'm working with information that is not totally clear yet).
So, the situation is the one that follows:
Big Group = 80 Students
divided in:
Group A = 20 Students
Group B = 20 Students
Group C = 20 Students
Group D = 20 Students
1 teacher
1 room
Lecture period= 10 weeks, only in the morning
hour = 15 minutes, 24 hours of 15 minutes a day, (from 8:30 to 14:30).
Activity I = Big Group + 6 hours (of 15 minutes each)
Activity IA = Group A + 4 hours (of 15 minutes each)
Activity IB = Group B + 4 hours (of 15 minutes each)
Activity IC = Group C + 4 hours (of 15 minutes each)
Activity ID = Group D + 4 hours (of 15 minutes each)
Break = 4 hours
Week 1 /day 1 = Activity I
Week 2 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 3 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
day 2 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 4 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 5 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
day 2 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 6 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 7 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
day 2 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 8 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 9 /day 1 = Activity IA + Activity IB + Break + Activity IC + Activity ID
Week 10/day 1 = Activity I
day 2 = Activity IA + Activity IB + Break + Activity IC + Activity ID

I Need to insist with this, because I can not find the way, thanks for your help
I do not understand your problem. Could you explain the real data and FET data? Tell me the real number of days per week, hours per day and other information, and how you inputted this data into FET: FET number of days per week, number of hours per day. And I do not understand what you are trying to schedule. In FET, you can only schedule for a "week" (this week may have 35 FET days). What are you trying to do?
Ok, there we go:
5 days per week
24 hours per day (each hour is a 15 minutes period)
the other data is in the previous post.
the thing is that I have regular Activities per week, I mean 1 session per week of every activity (during 10 weeks, which is not relevant for these regular activities). BUT in between these activities I have this IRREGULAR one, the one that I named Activity I, that has 4 related activities or subactivities called IA, IB, IC, ID. The stuff is that "I" is a session of 6 hours, and IA, IB, IC, ID are of 4 hours each.
Besides "I" is only in the first and last weeks (of the ten weeks, in here is relevant the amount of weeks), while IA, IB, IC, ID, are almost every week, except for the first week, some weeks once a week, and some others, twice a week.
And the last week one of the days is ACTIVITY I, and a second day are ACTIVITIES IA, IB, IC, ID
I, hope is clear enough, if not, just keep asking, and thanks again.
Sorry I forgot, these are the only activities (IA, IB, IC, ID) where IA and IB have to be consecutive, then a gap of 4 hours, that I have called break at the INFO that I sent you first, and after the gap IC and ID consecutive.
Maybe I have understood now.
I suggest this: make a separate .fet data file for each week (10 files).
In each file, add all the other activities and the needed special I... activities.
I'll exemplify for file 3 (week 3): lock the special activities to days Monday and Tuesday. Add activities "Break" (2 components). Min days between IA component 1 and IA component 2 = 1 days, 100%. Add 4 constraints 2 activities consecutive: IA comp. 1, then IB 1, second constraint: IB 1, Break 1, 3rd constraint: Break 1, IC 1, 4th constraint: IC 1, ID 1. This is for the first day. Then add another 4 constraints 2 activities consecutive for day 2.
All right, excellent idea, I will do it and I will let you know how goes on.
Thanks a lot. :)
I forgot this: if you want the normal activities to have the same place for all the 10 timetables (one for each week), you need to lock them.
Probably a good idea is to schedule firstly the most difficult week (probably week 3) and lock normal activities. Then, remove special activities for week 3 and add special activities for week x (x from 1 to 10, without 3).
Thanks again, I was just now over that issue, i mean planning how to do it. ;)
Thanks Again to you Liviu and Volker, everything is going on silk. :)
