Within the scope of the research project, a methodology for a model-based Life Cycle Engineering (LCE) of structural parts and components of future vehicle generations is to be developed and implemented in a software functional model. Existing approaches in lifecycle-oriented development of automotive components severely limit the variability of the background system and the results generated with it represent only one possible lifecycle scenario. Model-based LCE solves this problem by integrating different subsystems, i.e. different technical processes in the life cycle, and quantifying the energy and material flows accordingly. Additionally, there are models for different product descriptions as well as for different background systems, e.g. energy demand and consumption. This comprehensive software functional model is intended to support engineering processes, especially in concept development, and to provide information about the advantages and disadvantages of different design and manufacturing options under variable boundary conditions.
