ABSTRACT:
The system includes equipments necessary for demand registration and control organized hierarchically. The uppermost hierarchy level includes an operations control center and station equipment connected to the operations control center. The operations control center indicates the operation necessary at the next hierarchy level in accordance with the demand registered in the station equipment. The next hierarchy level includes one or more command and control centers. Each command and control center checks the commands of the operations control center and/or of the associated station equipment, giving special consideration to safety criteria, and passes on the commands to the last hierarchy level for execution. The last hierarchy level includes operation facilities, such as vehicles, which perform the requested transport tasks, continuously exchanging information with their associated command and control center.
