This problem captures some essential challenges faced by a logistics provider which operates transportation services for a limited number of partners and should respect contractual obligations on service levels. The problem also generalizes several important classes of vehicle routing problems with profits. To solve it, we propose a compact mathematical formulation, a branch-and-price algorithm, and a hybrid genetic algorithm with population management, which relies on problem-tailored solution representation, crossover and local search operators, as well as an adaptive penalization mechanism establishing a good balance between service levels and costs. Our computational experiments show that the proposed heuristic returns very high-quality solutions for this difficult problem, matches all optimal solutions found for small and medium-scale benchmark instances, and improves upon existing algorithms for two important special cases: the vehicle routing problem with private fleet and common carrier, and the capacitated profitable tour problem. The branch-and-price algorithm also produces new optimal solutions for all three problems. date: 2017 date_type: published publisher: Elsevier official_url: http://www.sciencedirect.com/science/article/pii/S0377221717307580 full_text_status: public publication: European Journal of Operational Research refereed: TRUE issn: 0377-2217 citation: Bulhões, Teobaldo and Ha, Minh Hoang and Martinelli, Rafael and Vidal, Thibaut (2017) The vehicle routing problem with service level constraints.
