Your constraints for the gaps of teacher "poth" are useless, because you have lower gaps for all the teachers.

I thought the special case (constraint one teacher) overrides the general case (constraint for all teacher) 

Maybe there is no solution for the plan. I first tried only the cpomplex year (Q2), and found a solution. Than i activated one year after another and tried different combination, but the maximum were a plan for 5 years (from . Do you have an idea, how to find the critical point?

I tried to calculate a timetable for the attached data. That are all activities for my school. In the upper grade (Year EF,Q1,Q2) i created a group for each course, every student of this course is a subgroup of this group.

There are a few teacher with not available times. Lower Grades have only as much available times as the have lessons.

There are a group of activities which have to be a specified times (They have the activity tag: Band T9, band T10, Band T13 and Band T14 with a total duration of 5). I put a  "activity preferred timeslots" constraint and only allowed 5 timeslots.

If i look to the "initial order of placing activities"  this activities are not a the first place, but i think this has to be, because there is only one solution.

Can someone help me?

thank you.

Thank you, this works for me

Hi,
i think that is what i need:

100% 2,1a, 100% 2,1b, 100% 2,1c, 100% 2,1d, 100% 1a,1c, 100% 1a,1d, 100% 1c,1d. Then, 95% 1a,1b,1c,1d (or 95% 1a,1b, 95% 1b,1c, 95% 1b,1d if you prefer like this).

Is 95% 1a,1b,1c,1d  really the same as   95% 1a,1b, 95% 1b,1c, 95% 1b,1d ?

Is 95% the right weight, if it is regardless, if 1b occurs in a double periode or as a single period?

Thank you

Hi, and thanks again,

but i want to allow one further double period. If fet finds a solution with two double periods and one single period, this should be an allowed solution. If fet finds a solution with one double period and 4 single periods this  also should be an allowed solution. If fet finds a solution with 3 double periods this should not be allowed.

Idea: I make 4 min days constraints 100% between 2/6 and each of the 1/6; then, 2 min days constraints 100%: 1a <-> 1c, 1a <-> 1d and 1 min days constraints with weight < 100% between 1c <-> 1d. So fet can create a double period from 1c & 1d.

- If this works, which value should i use for the third constrains (min days constraints between 1c <-> 1d)?

One Question
If fet generates a plan an find a timetable where 1a & 1d build a double period and 1c & 1d not. For fet this is no solution (100% 1a<->1d), but for me it is,because 1a and 1c are equivalent and can be swap in this plan.  Is this right, or do fet also swap  equivalent activities?

Hi and thank you for your replay:

I didn't test it, but if i put 4 min day constraints like

1: 2/6 and 1/6a
2: 2/6 and 1/6b
3: 2/6 and 1/6c
4: 2/6 and 1/6d

isn't a timetable like

Day I: 2/6
Day II: 1/6a and 1/6b
Day III: 1/6c and 1/6d

possible?

But i maximum want to allow:
Day I: 2/6
Day II: 1/6a and 1/6b
Day III: 1/6c
Day IV: 1/6d

and minimum

Day I: 2/6
Day II: 1/6a
Day III: 1/6b
Day IV: 1/6c
Day V: 1/6d


Thanks

Hi,

i have an activity with a duration of 6, which should be teached in 1 or 2 double periods. Because of this i created an activity with 4 sub activities
2/6, 1/6, 1/6, 1/6, 1/6. I set "min-Days between activities" to 1 an the weight to 95%. Generating a plan, sometimes i get 3 double periods. Is there a way to force fet to build maximum 2 double periods.

Thanks

Thank you for your replies.

I tried Livius and it fits to my needs.

Thanks.

Hi,

I have the following Situation:
In my school there are 8 periodes every day. But One class only has lessons in the first 6 periodes. Because of this i set ConstraintStudentsSetNotAvailableTimes to periode 7 and 8 every day. Now there is one lesson in this class, which is allowed to take place in period 7 of two days, if there is no other solution. How can I achieve this?

Thank you

Thank you for reply.

If i understand right, the number of subgroups has no limit (it's only limited by the GUI). But virtual i can add as many subgroups i like?

Hi,

i've the following situation: In year 9 there are the sections a, b, c, d. The students can choose their first and second language, they can choose one of 4 different additional sciences and they also divided by their religion.

How do i've to divide the year. There are only 3 categories?

Thank you

I,

i want to try to import datas from our school-database to fet. Is there somewhere an documentation for the .fet file? Especially for the constraints?

Thanks, Martin

Hallo,

folgende Situation:

In der Klasse 5 habe ich die Klassen (Gruppen) 5a, 5b und 5c, sowie den Kurs (ebf. Gruppe) 5RE für Religion, der klassenübergreifend unterrichtet wird. Ich habe dann die Teilgruppen 5aRE, 5bRe und 5cRE angelegt, und so zugeordnet:

Jahrgang	Gruppe	Teilgruppe
5	5a	5aRE
5	5b	5bRE
5	5c	5cRE
5	5RE	5aRE,5bRE,5cRE

Dann habe ich eine Aktivität für 5aRE eingerichtet mit den entsprechenden Religionslehrern.

Nun meine Frage:
Ich möchte gerne, dass diese Aktivität 3 Räume zugewiesen bekommt (da etwas knappe Raumsituation und ich gerne möchte, dass FET die Räume mit plant)? Bis jetzt habe ich nur die Möglichkeit gefunden über "Klassenraum" einen Raum einer Schülergruppe zuzuweisen. Gibt es auch die Möglichkeit 3 Räume einer Aktivität zuzuweisen?

Vielen Dank

Hallo,

wie hier http://lalescu.ro/liviu/fet/forum/index.php?topic=934.0 schon etwas diskutiert, versuche ich gerade einen Stundenplan für ein Gymnasium mit FET zu erzeugen.

Ich habe folgendes bisher gemacht:
Import der Schüler und Kurse als Gruppen und Teilgruppen

"Jahrgang","Gruppe","Teilgruppe"
"12","e1","Hans Meier"
"12","e1","Max Mustermann"
"12","e1","Susi Schneider"
...
"12","m1","Hans Meier"
"12","m1","Susi Schneider"
"12","m1","Helga Schulz"
....

Dann habe ich entsprechende Aktivitäten eingerichtet/importiert:
Hansmann - Mathematik - 12 m1 Hans Meier, 12 m1 Susi Schneider, 12 m1 Helga Schulz

und

Schmidt - Englisch . 12 e1 Hans Meier, 12 e1 Max Mustermann, 12 e1 Susi Schneider

Also jede Teilgruppe entsprechend die Aktivität zugewiesen.
Nun habe ich einen Plan generiert, und es liegen e1 und m1 parallel. Das dürfte aber nicht sein, da ja gleiche Schüler darin sind.

Irgendwie muss ich die Aktivitäten wohl anders einrichten? Es sieht so aus, als wenn die Teilgruppe 'e1 Susi Schneider' und 'm1 Susi Schneider' nach FET parallel liegen dürfen? Muss ich beim Einrichten der Aktivitäten die Gruppe 'Susi Schneider' (und nicht die Teilgruppe 'e1 Susi Schneider') zuweisen?

Vielen Dank

Ok, dann habe ich es jetzt glaube ich verstanden.

Ich war nur etwas irritiert, weil die Anzahl der Subkategorien in der GUI relative gering war. Aber intern dürfte FET dann ja mehr verarbeiten.

... Ah ja, steht ja auch unter Features auf der Homepage ...

Habe dann gerade mal Testweise ein *.csv importiert, klappt super. Bin begeistert von der Schienenlosigkeit. Man kann ja Abschätzen wie viel mehr Möglichkeiten es gibt.

Vielen Dank, dann geht's in Kürze los.
