In effect, this is an additional cost applied per hour of lateness. This constraint affords the user finer control over respect for visiting time windows. Caution: using constraints linked to tolerance can have a blocking effect on the optimisation calculation by making lateness the main priority.
Format: numeric (integer or real number)
Example:
I accept making a series of detours and therefore covering extra kilometers in order to better respect the delivery times
as defined.
I accept travelling an extra 70 kilometers to avoid 5 minutes late arrival at the customer.
So, 0.5 x 70 x 12 (=60/5min) = 420
(0.5 being the expression of the resource’s Cost per km constraint)
The value to enter under the Penalty per late hour constraint is 420.
