Method for controlling the material flow of goods being conveyed in a conveyance technique of a real warehouse by means of a virtual three-dimensional model, for which purpose the conveyance technique of the real warehouse is virtualised in a central computer, for which purpose a virtual three-dimensional model of the real conveyance technique with the dimensions of the individual conveyance technique component, its movement parameters and actuator properties and the identity, form and position of the goods being conveyed is stored, and the conveyance technique of the real warehouse is controlled centrally from the virtual model; images of the goods being conveyed in the real conveyance technique are cyclically captured by means of sensors and the virtual model is cyclically adjusted to reality on the basis of the images taken, whereby the conveyance technique comprises a conveyor system, which comprises a distribution path which conveys packets inwards and outwards and paths into and out of storage are arranged between the distribution path and the storage racks, which are connected to the distribution path by inducts and discharges and are connected to the storage rack aisles via goods lifts, whereby the distribution path and the inward and outward paths are roller conveyors or belt conveyors, and whereby packets are transported by the goods lifts from the inward paths into the rack levels of the storage racks or from the rack levels to the outward paths and a transport of the packets is made within the rack levels of the storage racks via rack serving apparatuses, whereby in the region of the feed of the distribution path images of the distribution path are taken at cyclical intervals by an IP camera and also IP cameras (Ki, ii, iv, v...) are arranged on the rack serving apparatuses and in the region of the actuators and outwards paths, so that so that a synchronized model of the technique including the packets with all the information required to trigger actuators is available in the computer, and the computer generates commands to the actuators from this information and the requirements of the management system in order to control the material flow in a targeted manner, whereas the packets are identified from the captured images of the IP cameras in the central computer by means of image recognition, their form is translated into a three-dimensional model and their position at the point in time of image capture in the real conveyance technique is determined and the virtual model is adjusted cyclically on the basis of the identification and position determination. for which purpose the conveyance technique of the real warehouse is virtualised in a central computer, for which purpose a virtual three-dimensional model of the real conveyance technique with the dimensions of the individual conveyance technique component, its movement parameters and actuator properties and the identity, form and position of the goods being conveyed is stored, and the conveyance technique of the real warehouse is controlled centrally from the virtual model;
