- the logistics area 100 may be divided into a plurality of zones. In this case, as shown in Fig. 2a, a relatively coarse division into zones 201 or, as shown in Fig. 2b, a relatively fine division into zones 201 are made.
- the control unit 110 may be configured to reserve one or more zones 201 of the logistics area 100 for a particular transport system. A transport vehicle 104, 105 of the particular transport system may then move freely within the one or more zones 201 reserved for the transport system. For example, as shown in Fig. 2a, a first
- Transport system a first zone 204 and a second transport system reserve a second zone 205.

- a transport vehicle 104 of the transport system for which the one or more zones 201 have been reserved may then enter the one or more reserved zones 201. After passing through the one or more reserved zones 201, they can then be released again to the control unit 110 by means of a release message. The control unit 110 may then reserve the one or more shared zones 201 for the next transport system. So can reliably operate several different transport systems in a logistics area 100.
- Each zone 201 can be driven only by a transport vehicle 104, 105.
- the communication between the different transport systems and a central zone management 110 may be via a standardized communication interface 111.

- a transport vehicle 104, 105 may have location means or access location means that allow the location of the
- 105 position data can be determined which indicate which one or more zones 201, 204, 205 are occupied by the transport vehicle 104, 105 at a particular time and which one or more zones 201 on the preceding travel route for the Transport vehicle 104, 105 should be reserved.
- zones 201 for a transport vehicle 104, 105 can be gradually reserved and released again along a travel route.
- FIG. 3 a shows a flowchart of an exemplary method 300 for operating a plurality of transport systems with a plurality of transport vehicles 104, 105 in a logistics area 100.
- the method 300 may be implemented by a
- Control unit 110 in particular by a zone management system, the
- the logistics area 100 are executed.
- the logistics area 100 is in one Divided into a plurality of zones 201.
- the loading / unloading areas 103 and the transport areas 101 of the logistics area 100 are subdivided into different zones 201, wherein the different zones 201 for the one or more transport vehicles 104, 105 can be reserved by different transport systems.
- the method 300 includes receiving 301 a first reservation request to reserve one or more zones 201 of the logistics area 100 for a first transport system (in particular for a first transport vehicle 104 of a first transport system).
- the reservation request may indicate that the first transport system wishes to use the one or more zones 201 for transporting goods within the logistics area 100.
- Reservation request can be received via a (possibly wireless) communication link 111.
- the method 300 includes determining 302 an occupancy state of the one or more zones 201.
- the control unit 110 may be configured to store the current occupancy state for each zone 201 of the logistics area.
- the occupancy state of a zone 201 may indicate whether the zone 201 is currently reserved for a transport system or not.
- the method 300 further includes reserving 303 the one or more zones 201 for the first transport system, depending on the
- the one or more zones 201 may be reserved for the first transport system when it is determined that the one or more zones 201 have not already been reserved for another transport system.
- typically no reservation can be made as long as at least one of the one or more requested zones 201 are still reserved for another transport system.
- 3b shows a method 310 for operating a first transport system in a logistics area 100. The method 310 can be executed, for example, by a control module of the first transport system and / or a transport vehicle 104 of the first transport system.
- the method 310 includes determining 311 that a transport vehicle 104 of the first transport system will enter on one preceding travel route into one or more zones 201 of the logistics area 100. This can e.g. are determined based on position data relating to a position of the transport vehicle 104 within the logistics area 100.

- the method 310 includes receiving 313 a response to the reservation request.
- the feedback may e.g. indicate whether or not the one or more zones 201 could be reserved for the first transport system.
- the feedback can be sent via a (possibly wireless)
- the method 310 further includes causing 314, in response to the feedback, that the transport vehicle 104 enters the one or more zones 201.
- the transport vehicle 104 of the first transport system may be caused to enter the one or more zones 201 when the feedback indicates that the one or more zones 201 have been reserved for the first transport system.
- the transport vehicle 104 may be caused to wait for a successful reservation of the one or more zones 201 or to change its route through the logistics area 100.
- the allocation of zones 201 to different transport vehicles 104 of different transport systems may be part of an overarching Traffic control system.
- the zone concept described in this document (with a multi-dimensional structure of a logistics area 100 in zones 201, with a reservation option and / or with a booking of use) can be part of an overarching
