Abstract
Creating and maintaining an efficient distribution network is essential for companies in the modern pharmaceutical industry. Medicine delivery usually takes place via depots and/or satellites, and the proposed model for assessing the issue determines the facility and routing decisions simultaneously. We develop a technique that iterates between an upper bound and a lower bound, based on a blended Lagrangian relaxation branch-and-cut approach where we exploit separability and linearity. We conducted computational experiments on real-life instances from the Dutch pharmaceutical industry distribution network. We show that the solution method can provide solutions for real-life cases within reasonable time windows.
