VisitPenalty

If a dynamic column "VisitPenalty" is created in the locations page and filled with a value, the first visit of any vehicle to this location will be without penalty, any further visit by another vehicle will be charged with the given penalty.

Why?

In many cases the solver can come up with a solution, that serves multiple customers at the same location using multiple different vehicles.

This can occasionally be cheaper (due to the distance matrix not being triangular, or due to the fact that distance cost > time cost) but the planner may find it odd or the drivers may consider it bad planning, regardless of the cost.

There can also be a customer / receiver annoyance “penalty” when it is actually the exact same customer served multiple times in the schedule.
