Martin Eigner and Patrick Schäfer turn towards sustainability of engineering perspective. For these is development of sustainable products a central condition for survival or increase of competiveness of global acting companies. Ecological motivation is explained by climate change, proceeding tightening of natural resources and forming of an increasingly ecosensitive society. Companies with location in Germany are anxious to optimize their innovation potentials for a sustainable dealing with energy and resources. Thereby companies see a big chance to accomplish their contribution to a global sustainable paradigm and to break away from competing firms with ecological, economical and social product and process innovations.

They show that product lifecycle management is a concept that links existing avenues of approach, solutions and tools in a way that their common result leads in a greater measure as before to sustainable success. The approach makes it possible to keep track of complex product systems. They concrete this approach within the frame of modeling a mobile machine. Increases of energy costs, tighter getting resources, but even so climate change have faced the automotive sector new challenges. Therefore demand of more eco-efficiency increases also in mobile machines and agricultural engines. These challenges have lead to the joint project "Energie- und ressourceneffiziente mobile Arbeitsmaschinen (ERMA), which will be suggested in this contribution.
