Goal-oriented Life Cycle Investigations for Composite Manufacturing Chains

Holistic Life Cycle Investigations for products and the related manufacturing chains require large efforts. The pre-quantification of sensitivities for process inputs underscores their importance for the results and determines the required grade of accuracy for quantification. Those indicators support an expedient construction of process models for the LCA/LCC application. Furthermore, a pre-analysis of the differences between product systems for comparative investigations support an adequate and tailored setting of system boundaries. The approach for those goal-oriented Life Cycle Investigations is applied in a Use Case describing a manufacturing chain of automotive structural parts made of composites with a focus on environmental impacts. The results of the pre-analysis are used for recommendations and rules for an expedient development of LCA models and later investigations.
