1. A method for the computer-aided optimization for tool transporting operations for at least one tool magazine which has a number of magazine locations and which is used for a machine tool which is used to produce one or more workpieces using the tools provided by a magazine device at a provision location,
having the following steps:
a) detecting, by a control device having at least one processor, a quantity of tools,
b) detecting, by the control device, the space required for each tool,
c) detecting, by the control device, a quantity of magazine locations which are occupiable for each tool,
d) detecting, by the control device, a permissible initial magazine occupancy, wherein an initial magazine location is detected for each tool,
e) detecting, by the control device, the permissible target magazine occupancy, wherein target magazine locations are detected for at least one subset of the detected quantity of tools for which a tool transporting operation is to be carried out,
f) detecting, by the control device, a quantity of transportation time periods which are respectively required by a movement of the magazine device from one magazine location to another magazine location,
g) determining, by the control device, a subset of tool transporting operations for which a transportation sequence is specifiable, so that in this transportation sequence the tools are moveable to their target magazine location without a collision in respect of the space required by their occupied magazine location,
h) optimizing, by the control device, the transportation sequence for this subset of tool transporting operations in such a way that the sum of the transportation time periods required for these tool transporting operations is minimized, and
i) performing, by the control device, the tool transporting operations on the basis of the optimized transportation sequence.
