1. A method for controlling a material flow system, wherein the material flow system includes vehicles for transporting goods packages, wherein the vehicles communicate autonomously among one another in the material flow system, wherein the vehicles moves by movement steps along a material flow path from a starting node to a target node, wherein each movement step of a vehicle comprises movement from a first node to a second node, and wherein a logical clock is associated with each node, the method comprising:
providing each movement step of a first vehicle with a time stamp; and
carry out movement steps such that for the first vehicle, successive movement steps assume monotonically increasing values for the time stamp and such that for each node that is traversed, an outgoing movement step of the first vehicle has a value of the time stamp which is less than or equal to a value of the time stamp for a subsequently incoming movement step of a second vehicle.
