Requirements and Targets for theMigration Concept in the Body-in-White Production


Flexibility through Movability

[BMW]


Re-Use of Production Equipment

Plant and Equipment Layouts

A209

The re-use of production equipment is in principle possible. However change-over strategies and adaptation is difficult and often not possible. After end of production (EOP) the integration of a new model is possible.

Therefore EOP and SOP are directly related to each other.

Summary

- Life-style effects in the market and technical innovations require continuously

new car models in short sequence and with decreasing product life-cycle.

A high competitive pressure requires low cost and

low budget production concepts.

The Body-in-White production is a key element in the automotive

manufacturing process.

A Body-in-White production based on the new Migration Concept is much more

advanced compared to the existing production concepts in respect of flexibility, economics and investment and market risks.

Migration Manufacturing is a new concept for factory planning. It reflects the idea that plant layouts are a living organism that pro-acts with market and technology changes.
