This paper presents a memetic algorithm for a pick-up and delivery problem. The specific application studied here is the personnel transportation within a set of oil platforms by one helicopter that may have to undertake several routes in sequence. Different versions of the algorithm are presented and tested on randomly generated instances as well as on real instances provided by a petroleum company. The results show that the solutions obtained are 8% better than construction and improvement solutions on randomly generated instances.
