Questions and answers on Production Control
Production planning defines, on a medium- to long-term basis, what needs to be manufactured, in what quantities, and by when. Production control, on the other hand, handles the short-term, operational execution of these specifications directly on the shop floor. While planning establishes the theoretical framework and rough capacity estimates, production control manages and monitors the physical implementation at the machines in day-to-day logistics operations.
A Manufacturing Execution System (MES) digitizes the continuous exchange of information between the management level (ERP) and the individual production machines. It enables real-time production data acquisition (PDA), allowing control centers to react immediately to quality deviations or malfunctions. Consulting experience shows that full data transparency—which is essential for systematically reducing lead times—can only be achieved through the use of an MES.
Capacity control ensures that at no time are more orders scheduled than machines and personnel can handle. If this balance is disregarded, bottlenecks, queues at workstations, and inevitable delays in the production flow immediately arise. By precisely matching available resources, a smooth throughput is achieved, ensuring on-time delivery to the end customer.
Lean Management methods such as Kanban decouple rigid planning targets from actual order release and link them to real material consumption. Accordingly, a production order is only released and scheduled when the downstream station signals that it has the necessary capacity. This consumption-driven methodology effectively prevents overproduction and reduces costly buffer stocks within the factory to a minimum.
