Vehicle routing 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, and time windows...

Users can carry out flexible interaction (insertion, deletion, and move) on maps and Gantt chart at all levels of planning in an optimal way.

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...

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, and mileage..
