Publication number: 20210018922Abstract: A method performed at a mobile transport unit is disclosed. In the method, parameters are determined by using sensors of the transport unit. The parameters include characteristics of the transport unit and/or characteristics of a consignment transported by the transport unit. In the method, the parameters are transmitted to a routing system, which determines a transport route for the transport unit, a need that waypoints/timing of an existing transport route of the transport unit has to be changed to obtain a changed transport route, or a need for a specific handling of the consignment. In the method, an instruction is received that is a routing instruction from the routing system pertaining to the determined transport route for the transport unit, to a transfer of the consignment from the transport unit to another transport unit, or to how the consignment shall be handled by the transport unit.Type: ApplicationFiled: July 17, 2019Publication date: January 21, 2021Applicant: Deutsche Post AGInventors: Anja Scheer, Christoph Dautz, Lutz Fischer

Publication number: 20190020578Abstract: A method for routing is disclosed. The method involves obtaining information on a plurality of to-be-transported entities (TBTEs) that are each associated with a respective pick-up position and a respective drop-off position; determining a set of one or more transport routes (TRs), each of the TRs associated with a respective transport entity (TE) and defining a respective sequence of waypoints, wherein the set of TRs is determined to at least fulfil a criterion that, for each of the TBTEs, the pick-up position and drop-off position are associated with respective waypoints of the same respective TR or the pick-up position is associated with a respective waypoint of one TR and the drop-off position is associated with a respective waypoint of another TR that is connected with the one TR; and providing respective representations of at least a part of the TRs to the respective TEs associated with the TRs.Type: ApplicationFiled: July 13, 2017Publication date: January 17, 2019Inventors: Clemens Beckmann, Karin Pientka, Lutz Fischer, Lars Krämer, Jens Vygen, Stephan Held, Dirk Müller
