Hi,
In my usecase I need to plan tasks (PlanningEntity).
I have two kinds of tasks (for example CleaningTask and InspectionTask (inspect that
cleaning was OK)).
Each taskneeds to be assigned to a person and a period.
Person and period both are PlanningVariables.
I need to ensure that a person does not execute an InspectionTask twice in a row.
How can I find out what the previous task is that is assigned to a person?
It is not guaranteed that the person had a task in the previous period (period-1).
Thanks,
Michiel

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.

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
