The life cycle modeling of emissions in production, utilization and recycling of a car - a step to the LCA of a generic car

摘要

One of the problems of a LCA is the complexity of the considered systems. Results depending strongly on the boundary conditions. More appropriate is to parametrize the LCA and enable it for variations. With that the Life Cycle Modeling and Simulation leads to a deeper understanding of the examined system. Design parameters, like the geometry or the material of the part can be varied as well as the mass and energy flow in the process chain or methodological parameters. This is especially necessary in the early stage of the design process as a tool for sensitivity analysis and optimization of products. A dominance analysis ensures that the complexity of the model is suitable for goal and scope of the study.
