According to the controlling concept, the set goals need to be constantly checked. In the case of discrepancies, a regulating operation will be made in the system, to achieve the planned production goals (control loop).
The approach described here deals with a controlling system for monitoring productivity. The method is based on the experience that a simple comparison of the actual produced quantities with the production plan is not appropriate for controlling purposes. The point is basically to separate commercial influences from technical influences.
On the base of fundamental examples the relationships are explained for a production of web-shaped goods (paper, paperboard, foil...).
Furthermore, a simulator app has been developed, to study the influence of the distinct planning parameters online.
