Subject: New strategies for the cyclic maritime inventory routing problem


Andréa Cynthia Santos, Full Professor, LITIS-ISEL, Université Le Havre Normandie

Sebastiàn Urrutia, Full Professor, Molde University College

Team Laboratory: RI2C, LITIS

The « Laboratoire d’Informatique, de Traitement d’Information » (LITIS) is a multi-site research Laboratory in Rouen and Le Havre cities, in France. LITIS is composed of seven research teams covering fields such as combinatorial optimization, machine learning, Biomedical information processing, and operational research. This PhD position will be opened in the RI2C team in Le Havre city, which is specialized on intelligent networks systems, applied to applications in application fields of logistics, risk management, among others. This thesis will be developed in partnership with Molde University College, Department of Logistics.


The Maritime Inventory Routing Problem consists in delivering a set of ports using vessels, by transporting a product from a production port to consumption ones. Both production and consumption ports, respectively, produces and consumes at a given rate. The transportation service has to ensure that the consumption does not run out of products on a time horizon, and the inventory capacity have to be satisfied. A typical application is on supply of gas and fuel, which are usually continuous over the time.  This problem is addressed by cyclic routes leaving the production port to delivery all consumption ones. Recently, we have developed an alternative strategy, in which the cyclic routes are reversed after each complete route. The first ever results on a simplified version of the problem has shown a very relevant impact on the transportation costs. In this thesis, we intend to generalize the approach, introducing more realistic issues such as load-dependent routing, other objective functions, time and cost of loading and unloading operations, and problems with multiple vessels and multiple production ports. Realistic data is available for testing the proposed models and methods.


Candidate profile:

  • Master or similar diploma in operational research, computer science, industrial system or engineering school.
