Method for the throughput-optimized production of printed circuit boards on at least two pick-and-place lines, wherein the printed circuit boards are divided into groups called clusters, wherein a cluster is produced in each case by means of a fitting, wherein the fitting is realized by shuttle tables which are attachable to the pick-and-place lines and which each have at least one feed device for keeping ready supplies of components, wherein a quantity of shuttle tables required per fitting is referred to as a shuttle table set and an empty shuttle table set has shuttle tables with feed devices that are empty, - wherein a fitting is mounted temporarily on empty shuttle table sets and is demounted after the production of printed circuit boards as a result of the population thereof, and - wherein one of the shuttle table sets is usable in production only if it has been completely equipped in a prefitting region, and the shuttle table set is equippable again only if production carried out with the shuttle table set has ended and the shuttle table set has been stripped again in the prefitting region, wherein the method comprises the following steps: a) detecting a set of pick-and-place lines, b) detecting a set of clusters, c) detecting a number of empty shuttle table sets per pick-and-place line, d) detecting the respective time durations for creating the fitting for the individual clusters of the detected set of clusters per pick-and-place line, e) detecting the respective production time durations for producing the individual clusters of the detected set of clusters on one of the pick-and-place lines, f) selecting an assignment of shuttle table sets to positions in a temporal order in which the shuttle table sets are equipped in the prefitting region and are used in the same temporal order in production, wherein the number of positions in the temporal order corresponds to the number of detected clusters and each position is assigned a cluster, g) optimizing an assignment of the clusters to the pick-and-place lines and the order of the assigned clusters per pick-and-place line, such that the turnaround time is minimized overall relative to all the pick-and-place lines, h) carrying out the production of the printed circuit boards with the aid of the optimized assignment and order of the clusters calculated in g). - wherein a fitting is mounted temporarily on empty shuttle table sets and is demounted after the production of printed circuit boards as a result of the population thereof, and - wherein one of the shuttle table sets is usable in production only if it has been completely equipped in a prefitting region, and the shuttle table set is equippable again only if production carried out with the shuttle table set has ended and the shuttle table set has been stripped again in the prefitting region, - wherein one of the shuttle table sets is usable in production only if it has been completely equipped in a prefitting region, and the shuttle table set is equippable again only if production carried out with the shuttle table set has ended and the shuttle table set has been stripped again in the prefitting region, a) detecting a set of pick-and-place lines, b) detecting a set of clusters, c) detecting a number of empty shuttle table sets per pick-and-place line, d) detecting the respective time durations for creating the fitting for the individual clusters of the detected set of clusters per pick-and-place line, e) detecting the respective production time durations for producing the individual clusters of the detected set of clusters on one of the pick-and-place lines, f) selecting an assignment of shuttle table sets to positions in a temporal order in which the shuttle table sets are equipped in the prefitting region and are used in the same temporal order in production, wherein the number of positions in the temporal order corresponds to the number of detected clusters and each position is assigned a cluster, g) optimizing an assignment of the clusters to the pick-and-place lines and the order of the assigned clusters per pick-and-place line, such that the turnaround time is minimized overall relative to all the pick-and-place lines, h) carrying out the production of the printed circuit boards with the aid of the optimized assignment and order of the clusters calculated in g).
