Min lessons per day (per student per subject)

[Simon]

Hi,

I am not sure if this could be done for using current FET, but my school have this requirement on timetable:

We have 4 teachers teaching 9 lessons of English per week (5 days) for a class, and we at least 2 lessons per day with taught by different teachers. All lessons are single lesson.

Here is the structures created:
[A,B,C,D] 4 teachers
Activities 1,2,3 taught by teacher A
Activities 4,5,6 taught by teacher B
Activities 7,8 taught by teacher C
Activity 9 taught by teacher D

I have tried to use "min n days between a set of activities" (to space activities horizontally) and "min n gap" (to space activities vertically).

Is there a better way to set it up, as 9 single lessons need a lot of "min n days" rules !!!

Would it be better if there is a rule called: Min n lessons per day for a set of activities.

I am sorry, but I do not understand. Maybe I am tired :-)

I understand the requirement min n lessons per day for a set of activities. It is complicated, though.

I am not sure if i understood correct. But maybe you add this lessons as "single" lessons/activitiy. You should add them as "split" lessons/Activity, because the min n day constraint is added automaticly in that case. so you don't need to add that rules manualy.

I think I understand something
Those activities belong to a general subject called english, but activities 1, 2 and 3 belong to a specific subject within english, csay english-grammer for example
Likewise, activities 4, 5 and 6 belong to subject english-litterature
7 and 8 to english-linguistics
and so on..
Now, the problem is that, among those 9 activities,  no more than 2 activities should be taught per day for a class

I dont know, how this problem could be solved
However, I have some preleminary ideas:

1-I sugget to set subject of 1, 2 and 3 activities to be english1
4, 5 and 6 activities's subject to be english2
...etc

For all those activities, set an activity tag called english

Now, my question for Liviu:
can FET handle a requirememnt like this
Max hours daily with an activity tag for a student set ?
similar to:
Max hours continuosly with an activity tag for astudent set
which is already supported by  FET

2- Another trick would be to make a signle activity with 9 components,
But how to force FET to schdule no less and no more than  2 activities per day ?

3- We could also use Two activities are grouped/consecutive/
Or
Spread activities evenly over the week.
But dont know how

I'll think about that. It is complicated and probably very few will use it.

oh, oh, I would really use it if it could be done with subjects. I mean, max hours daily of this subject for a student group/set, or even if it could be combined with subject+activity tag if necessary.

[Liviu Lalescu]

Simon, we have a new constraint teacher(s) or students (set) activity tag max hours daily, in the latest snapshot. Maybe you would like to try it.
