More and more products are subject to volatile markets with poorly predictable and rapidly changing sales figures. This creates a need for transformable manual and hybrid assembly systems, because in a transformed assembly system, i.e. adapted to the new number of pieces, can again be produced economically. A basic transformation measure exists in the change of the assembly basic form or structure of the assembly system. For small-volume products are available a wide range of mounting system structures with the single job, the row assembly, the flow assembly, the U-line or even one-piece-flow-system, the one-set-flow-system, the indexing table, the conveyor belt and the carrée belt. From this huge number to determine the best assembly system structure according to market situation is to be managed with the current planning methods only very time-consuming. A new resource-poor procedure for rapid identification of the most economical assembly system structure can be applied in daily operations at each change in the numbers of pieces. In this paper, the principle of the new procedure is introduced based on the quick determination of manual assembly times by means of approximate calculation.
