In contrast to the classical location-allocation models, the location-routing problem (LRP) integrates vehicle routing and scheduling aspects in the location planning process. A survey and classification scheme of location-routing is e.g. proposed by [3] and [2]. This paper presents a LRP of a company which distributes finished cars. This LRP is decomposed into two steps. In the first step a se...
