A method of preparing a setup kit (22, 24) for at least one placement machine, wherein the placement machine serves for the placement of components on/at assemblies; and wherein, in the method, by means of an electronic processing device, - those components that are required for the assemblies are determined for a plurality of different assemblies to be manufactured by means of the placement machine; - possible setup kits for the placement machine are prepared from the determined components, with each setup kit comprising a plurality of components, and with each setup kit including at most so many components that the components can be received by the placement machine; - an optimized setup kit is selected from the possible setup kits, wherein either that possible setup kit is selected as the optimized set-up kit with which the most different assemblies can be produced or that setup kit is selected as the optimized setup kit in which the fewest setup changes have to be carried out to be able to produce all the assemblies or the respective probable volume per time unit is determined for the assemblies, with that possible setup kit being selected as the optimized setup kit with which the most assemblies to be manufactured in the time unit can be produced; wherein at least 10,000,000 possible setup kits are prepared and the determination of the possible setup kits and/or the selection of the optimized setup kit takes/take place by means of distributed computer systems; and wherein the components that are required for manufacturing the assembly or assemblies to be produced most frequently are included in every possible setup kit. - those components that are required for the assemblies are determined for a plurality of different assemblies to be manufactured by means of the placement machine; - possible setup kits for the placement machine are prepared from the determined components, with each setup kit comprising a plurality of components, and with each setup kit including at most so many components that the components can be received by the placement machine; - an optimized setup kit is selected from the possible setup kits, wherein either that possible setup kit is selected as the optimized set-up kit with which the most different assemblies can be produced or that setup kit is selected as the optimized setup kit in which the fewest setup changes have to be carried out to be able to produce all the assemblies or the respective probable volume per time unit is determined for the assemblies, with that possible setup kit being selected as the optimized setup kit with which the most assemblies to be manufactured in the time unit can be produced; wherein at least 10,000,000 possible setup kits are prepared and the determination of the possible setup kits and/or the selection of the optimized setup kit takes/take place by means of distributed computer systems; and wherein the components that are required for manufacturing the assembly or assemblies to be produced most frequently are included in every possible setup kit. that possible setup kit is selected as the optimized set-up kit with which the most different assemblies can be produced or that setup kit is selected as the optimized setup kit in which the fewest setup changes have to be carried out to be able to produce all the assemblies or the respective probable volume per time unit is determined for the assemblies, with that possible setup kit being selected as the optimized setup kit with which the most assemblies to be manufactured in the time unit can be produced; wherein at least 10,000,000 possible setup kits are prepared and the determination of the possible setup kits and/or the selection of the optimized setup kit takes/take place by means of distributed computer systems; and wherein the components that are required for manufacturing the assembly or assemblies to be produced most frequently are included in every possible setup kit.
