is letter mail transportation and delivery. In this market segment there have been two key efforts during the last few years: reduction in transportation and delivery time (service quality) and minimization of costs under service quality constraints. Both efforts—reduction of service time and minim

Robert Magnus,Tim Postonticle we introduce the structure of a typical distribution network for letter mail and for parcel mail, and we describe the main subnetworks. This paper is also concerned with projects on optimization of such subnetworks. Therefore, we have selected three projects dealing with different subsystems a
