1. Introduction and Motivation
Objectives for development in the automotive industry:
Much more innovative cars need to be developed and will be
developed!
Managing requirements on the desired product is mandatory for
successful frontloading
Managing collaboration in conceptual design to improve efficiency
Creation and analysis of alternatives and use of optimization to fully
scan the design space available
Reversing the weight spiral is an objective
Strengthen collaborative design and engineering to improve “logistics
of knowledge” and remove obstacles
