Wie lassen sich neue Planungs- und Optimierungsverfahren aus den Bereichen der klassischen Montage auf die Branche Kabelkonfektion übertragen? Mit dieser Fragestellung beschäftigt sich der Vortrag. Hierzu werden die
etablierten Verfahren vorgestellt und auf Ihre Eignung untersucht. Anschließend werden Übertragungsmöglichkeiten aufgezeigt und an Beispielen visualisiert.


Nowadays there are tow main methods in planning of assembly processes. The first one starts with a detailed analysis of the assembly problem. In the second step, a rough concept will be designed which corresponds to the requirements picked up in step one. After developing a detailed concept, the layout of the assembly line and the design of the workplaces is designed in a detailed way. Also the simulation of the sequences takes places in this step. In the last step the realisation takes place. The alternative method is based on a catalogue with existing solutions. The assembly task will be divided to its basic steps. For each of the basic steps an existing solution will be selected from the known solutions and in a final step integration of the single solutions to a concept will be done.
The new methods "Wertstrom" and continuous flow can be used alternatively. With the Werstrom method the analysis of the existing material and information flow in an assembly planz can be done easily. Based on the analysis an ideal concept can be developed very quickly. The aim of this method is a sequential detection of assembly problems by a reduction of stocks in the assembly line. The proceeding results in lower stocks and a shorter pass-through time.
The basic aim of continuous flow is the total elimination of buffer stocks between the assembly steps. This results in very short pass-through times and an increased quality level. Combined with a flexible U-shaped assembly layout this also leads to a more flexible worker employment.
To implement this principle in assembly of wire harnesses, it is necessary to shift work from the jig board to subassembly places in which a connector assembly is done were planned. This leads to reduced working times on the jig boards.
