ABSTRACT
As with all efforts at optimization, the objective of a changeover reduction is to improve the situation. It is relatively easy to illustrate whether the changeover in the new situation needs less time than before. It becomes more difficult if the question has to be answered, whether this gain in time also represents an improvement from a commercial standpoint. Finally, the crucial point with all investments is always, of course, the answer to the question of when the expenditure is returned.
