| Description |
In the consistent vehicle routing problem (ConVRP) customers are serviced over a given planning period, e.g., several
days. Customer satisfaction is maintained by providing
driver and time consistent service. Driver consistency is
expressed by the number of different drivers that visit
a customer. Only one driver per customer is allowed in
the ConVRP. Time consistency is achieved by bounding the maximum difference between the earliest and the
latest arrival time at each customer. Vehicle idling
to reduce the arrival time difference is not allowed.
The objective is to find a minimum cost routing plan
that complies with the classical routing constraints and
the consistency requirements. |
