 Usually the supermarket is placed in the proximity of the work-places, so that the work-places have quick access to the needed materials.Every material has its own storage location in the supermarket (coordinates) so that it can be easily located when needed.The materials to be consumed are assigned by each workplace to the production order either by scanning them at the withdrawal from the supermarket (preproduction issuing) or by reporting them through the MES and Process control system (postproduction issuing).
