Bei den Automobilkonzernen geht die Tendenz in jüngster Zeit dahin, die Montage von Modulen für Kraftfahrzeuge weitestgehend auszulagern und sich von Zulieferfirmen bereits fertig montierte Baueinheiten eines Fahrzeugs liefern zu lassen, so daß im Montagewerk nur noch die Endmontage vorgenommen zu werden braucht.The trend in the automotive groups is very recent the assembly of modules for motor vehicles as far as possible outsource and get ready from supplier companies to have assembled components of a vehicle delivered, so that only the final assembly is carried out in the assembly plant are needed.
Insbesondere lassen sich die Automobilfirmen inzwischen komplett zusammengebaute Abgassysteme in die Montagewerke liefern, wobei die Vorlaufzeiten oftmals nur wenige Stunden betragen. Dies ist insofern problematisch, als Abgassysteme für Kraftfahrzeuge zwar in der Regel einen einheitlichen Grundaufbau besitzen, sie sich jedoch insbesondere in ihren Abmessungen und ihrer Form in Abhängigkeit vom Fahrzeug- und Motortyp stark unterscheiden können, so daß von den Zulieferfirmen zahlreiche Ausführungsvarianten von Abgassystemen bereitgestellt werden müssen.In particular, the automotive companies are now completely deliver assembled exhaust systems to the assembly plants, the lead times are often only a few hours. This is problematic in that exhaust systems a uniform one for motor vehicles Have basic structure, but they are particularly in their Dimensions and their shape depending on the vehicle and engine type can differ greatly, so that from the suppliers numerous versions of exhaust systems must be provided.
Wenn auf eine kostenintensive Lagerhaltung beim Automobilhersteller verzichtet werden soll, müssen die Zulieferfirmen flexibel genug sein, um innerhalb von kurzer Zeit unterschiedliche Abgassysteme zusammenzubauen. When it comes to costly warehousing at the automobile manufacturer The suppliers have to be waived be flexible enough to be different within a short space of time Assemble exhaust systems.
