An iterated local search for the biomedical sample transportation problem with multiple and interdependent pickups

This article addresses a new version of the biomedical sample transportation problem, as a vehicle routing problem with precedence constraints arising in the context of healthcare logistics, and proposes an iterated local search algorithm to solve it. This new version is more realistic and complex since it considers the collection centres’ opening hours and the moment at which they are visited as decision variables, granting additional...
