Vehicle routing problem (in particular, pick-up and delivery problem) is the main logistic problem at the ends of a supply chain, it involves dispatching vehicles globally and planning routes optimally subject to constraints such as capacity, load, work regulation, time windows...
|
 Truck constraints: |
 Transport capacity: quantity/volume/weight,
multi-tour, pickup and/or delivery
Vehicle consistency (product, max access)
Vehicle availability
 Customer order coupling
Customer priority... |
| Users can carry out flexible interaction (insertion, deletion, and move) on maps and Gantt chart at all levels of planning in an optimal way. |
Route constraints: |
Distance constraint: time/mileage/cost
Work regulation: time/break/make-span
Delivery time window |
| Objectives: |
|
Maximize the number of deliveries
Minimize the number of vehicles
Minimize work time, make-span, mileage... | |
