VeRoLog 2019: presentation of our work on multiple solving approaches applied to the Heterogeneous Vehicle Routing Problem

VeRoLog 2019: presentation of our work on multiple solving approaches applied to the Heterogeneous Vehicle Routing Problem

Gwénaël Rault, PhD student in Operations Research at Mapotempo, spoke during VeRoLog 2019 to present his work on the multiple solving approaches applied to the heterogeneous vehicle routing problem.

Discover all of his presentation above.

The technologies used: 

  • OR-Tools,
  • Vroom,
  • RADOS (développé par Flavien Lucas, PhD student à UBS & IMT Atlantique).

Description

We have combined several resolution methods to improve the overall result. To do this, we integrated the solver developed by Flavien Lucas into our optimization API in order to generate a first good quality solution and then improve it with OR-Tools. We started from the authorities of the literature to show the interest of the approach.

The prospects are in particular the improvement of the interaction between the methods and the use of these multiple methods for our future development, particularly on problems with geographical grouping and multi-modal optimization.
