Vehicle routing problems are very hard combinatorial optimization problems with significant economic and environmental challenges. The fundamental problem is to visit a set of customers with a given fleet of vehicles in order to minimize the total distance travelled. Moreover, these problems arise with a wide variety of objectives and additional constraints, related to the legislation and the diversity of industrial sectors. They are very common for many industries and the design of generic solvers has become an important research issue.This thesis focuses on the design and implementation of a new solver for the vehicle routing services offered by the company GEOCONCEPT. The proposed solver is based on constraint programming (CP) to improve...
