I have a problem with delivery routes which should not consists of more then say 4 locations (addresses). This constrained is being imposed by the transportation company (outsourced service) which imposes an additional fee (kind of a fine) for every additional (above limit) delivery point. So we would like to keep the maximum locations for a single truck which does not get fined.
Thinking about the solution we cannot directly use orders as there are usually a few orders for any given address to be delivered.
Any ideas how to implement such location maximum visit constrained?
