A method and an apparatus serve for controlling a system for simultaneously producing a plurality of different product kinds of confectioneries in a plurality of product lines. The method includes the steps of dividing a base mass into a plurality of partial masses, the base mass being a common mass for all product kinds and all product lines; mixing the partial masses with different aggregates to produce a plurality of different product masses, the aggregates varying depending on the respective product kind; further processing the product masses as reservoir masses; observing the consumption of the reservoir masses during further processing; refilling the reservoir masses with the respective product mass in response to the result of the observation of the consumption of the reservoir masses, wherein refilling takes place in each of the product lines in batches of product mass, refilling takes place in the product lines at different points in time, and the batches of product masses have approximately identical batch sizes, the batch size of a product masses being the amount of the product mass; and following to a production ending signal, changing the batch sizes and batch times of at least one product mass in a way that the reservoir masses of all product lines are exhausted at the same time.
