Abstract (en)
[origin: WO2018036622A1] The invention claims a method for determining optimum batch sizes for the placing of components (155) on circuit boards (120) within an assembly line, wherein a set of circuit board types (122) to be produced on the assembly line (110) within a specified planning period is specified; a number of circuit boards to be produced is specified for each circuit board type; the number of circuit boards per circuit board type forms a set that is to be divided into equal-sized subsets, also referred to as batches, which are production orders that are produced at regular intervals during the planning period; the batch size of a circuit board type is equal to the number of circuit boards in a subset; the specified circuit board types are divided into a set of clusters, wherein a cluster (210, 215) and its associated set-up (165, 170) comprises a set of circuit board types which can be produced with the associated set-up, and wherein the method includes the following steps: recording set-up costs that are incurred in setting up the associated set-up of a cluster; determining the time intervals between the production orders per circuit board type as a function of the batch size; determining the set-up costs per cluster during the planning period as a function of the batch sizes of the circuit board types and taking into account the recorded set-up costs; determining the total set-up costs from the sum of the set-up costs per cluster; determining the total storage costs of the circuit boards produced in a time interval within the planning period from the sum of the storage costs per circuit board type as a function of the batch sizes, and optimizing the batch sizes in such a way that the sum of the total set-up costs and the total storage costs is minimized.
