The tardiness and completion are variables, and the duedate is a constant.

How can I achieve this constraint in Python?

You can get split this into

Tardiness >= Completion - Duedate
Tardiness >= 0

(or just place a lower bound of 0 on Tardiness and only state the first constraint). I guess your objective function penalizes large values of Tardiness? In that case the solver will chose for Tardiness the smallest possible value, which is the max.

Hello

similar problem.  

Need I think a conditional constraint

Looking at the football schedule problem provided 

how about I have 

a match be a-b.  Where a plays at home against b who is away

and the Boolean matrix is a-b vs week

want a constraint 

b will only play two away games in a row if b is playing games

Hi

have you had a look at the example foodmanu.py in

CPLEX_Studio128\cplex\examples\src\python

?
