The aim of this work was to solve the switch-box routing problem to optimality by using a branch-and-price algorithm based on an IP model where variables represent Steiner trees and where the pricing problem becomes the problem of finding a Steiner tree in a graph. In the primal algorithm,...

This work presents a Branch-and-Price algorithm for solving a compressor scheduling problem with applications in oil production. The problem consists in defining a set of compressors to be installed for supplying the gas-lift demand of oil wells while minimizing the associated costs. Owing to the...
Hence, advanced algorithms are needed to solve the 2E-IRP heuristically and optimally. This paper proposes a novel exact branch-and-price algorithm for the 2E-IRP. The contributions are threefold: • We propose a mathematical model for the 2E-IRP, where customers can be visited from any ...

n this paper, we propose a reformulation and a Branch-and-price (BP) algorithm for the Vehicle Routing Problem with Cross-Docking (VRPCD). Our computational results indicate that the reformulation provides bounds much stronger than network flow bounds from previous studies. As a consequence, when...
