building change in a hurry...

[mbarsan]

Hi everybody!
We have a school with 8 periods per day, with a short break every 2 hours.
There are 3 buildings.
Teacher may change building during those short breaks.
So we  haven't to say to FET any duration to change buildings. This may be done at beginning of hours nn. 3, 5 and 7.
If a teacher works in a building at first and second periods, he may change building and work at third period.

We may chose to insert breaks times (students and teachers not available) between periods 2 and 3, 4 and 5, 6 and 7 to allow building change in a period. But now we can handle 3 hours lessons only with the constraint "two activities are grouped", using the same teacher and same class with (sub)activities of 1 and 2 hours. We have also problems with subactivities with duration 2 that FET may not put with a break inside (so we have to use the same trick as above).

Do you think that we may define a grid of hours to allow building changes only at specific periods?

Thank you!

I just added this in the TODO. But I think I will not do it (soon).

It is easy to code, but difficult to express in words. It is too specialized.

Ok, I undestand.
Thanks your prompt reply!

I have thought some more about this.

It may be possible in two ways:

a) To allow building changes only between a specified pairs of slots;

or

b) To allow exceptions to min gaps between building changes constraints.

I am willing to try at least to obtain a custom version. To incorporate this into the official is complicated.

I did this. Please get the custom version from http://lalescu.ro/liviu/fet/download/custom/velleca-crescenzo/ and let me know.
