Hi, I have some teachers to be available for substitutions. I want FET to choose this activity. Since I have three buildings and constraint min 1 hour gap between bld chng, I setup the following parameters:
-created subject Disp
-created three tags disp1, disp2, disp3 to be linked to the 3 buildings
-created activities for the teachers with disp, no groups, 1 or more tags because some teacher are available in more than one building
-created 9 rooms and linked to the building (3 rooms for each building) because I want to have max 3 teachers available at the same time
-set up the constraint space->tags->activity tags has a set of preferred rooms (tag disp1 - room1,room2,room3) (tag disp2 - room3, room4, room5)...
when I generate the simulation is impossible because I get the error as in the picture
UPDATE I found out that the problem comes from activities with more than one tag.
I don't know if it's a bug or it is simply not possible to allow multiple tags for an activity
By the way, I solved splitting in more subactivites and assigning to them a single tag, and it's now simulating
The way you descriped your problem and solution looks ok.
FET support multible tags. That shouldn't be the problem. (Of course it will care about ALL tags that you add). I done it very similar (but just with one buildung).
Maybe attach your (simplified) example file to check your problem.
