Process optimisation in the packaging industry of the power industry; Prozessoptimierung in der Verpackungsindustrie der Energiewirtschaft

The production of brown coal briquette bundles in a completely automated production plant imposes strict quality requirements on the pressing of the briquettes. Thus, the packaging of bundles which consist of several layers of briquettes requires that each layer has approximately the same length. As the pressing of briquettes with exactly predefined measurements cannot be mastered technically, a part of the production that does not meet the minimum requirements must be picked out with a suitable quality surveillance procedure. The quality surveillance procedure used in production can be described mathematically and is subject to an in-depth analysis. It can be verified that, besides the search for the optimal choice of single parameters, it is essential for this particular application that the performance of a quality surveillance procedure does not depend on the dynamic behavior of the factors of production. The result is based on mathematical modeling, optimization, and simulation by a computer-based model and led to a considerable increase in production output. (orig.)
