Hi Cedric,
Thanks for your comment.
How should I model this schedule object? I mean, at which point do I put a
'assignment' in the list?
Should I do this within a rule?
Could you elaborate a bit on this solution?
Thanks!
Michiel

same task twice in a row?
I believe you'll probably to create a schedule object that keeps track of all
assignments. From there , we can create a rule to assign a negative constraint
penalty to any schedules with two adjacent assignments for the same person with
the same task.
