Abstract: The generalized directed rural postman problem (GDRPP) is a generic type of arc routing problem. In the present paper, it is described how many types of practically relevant singlevehicle routing problems can be modelled as GDRPPs. This demonstrates the versatility of the GDRPP and its importance as a unified model for postman problems. In addition, a heuristic solution approach, based on a transformation into the generalized asymmetric travelling salesman problem (GATSP), is presented. Computational experiments using a state-of-theart heuristic for the GATSP (developed by Gutin and Karapetyan [27]) are performed, using a large set of realistic instances. The results show excellent solution quality in short computation time and thus demonstrate the practical usefulness of the transformations.
