VRP - multiple orders for same location
We used VRP to calculate service routes for our inspectors.
Customers could request multiple inspections under the same address.
To generate the most efficient route, we were expecting all the inspections for the same address and specialties to be assigned to the same inspector. In reality , we saw some same-address inspections were split and assigned to the same or different inspectors at different time. Customers were upset because the first inspection was done in the beginning of the day and the last inspection started after 3PM.
We tried using Order Pairs, but it only linked 2 orders at a time. Customers could request more than 2 inspections under the same address.
Any suggestions on how we can use VRP in this scenario?
