Circularity measures like repair, remanufacture and refurbish provide options to enhance the life cycle and thus the sustainability of a product besides measures, which primarily concentrate on the end-of-life of a product. To integrate the concept of circular value creation engendered by such measures in the development process of a product, we extended the idea of modelling standard life cycles as introduced by Block et al. [3]. This extension introduces the novel notion of undesired states within a product’s life cycle. Undesired states can be dissolved with the help of circularity measures. A Model Based Systems Engineering (MBSE) approach was developed to implement this strategy. The resultant modelling approach is implemented in form of a software tool. The system is evaluated within an automotive development project revealing a significant advantage in contrast to previous methods.

摘要

Circularity measures like repair, remanufacture and refurbish provide options to enhance the life cycle and thus the sustainability of a product besides measures, which primarily concentrate on the end-of-life of a product. To integrate the concept of circular value creation engendered by such measures in the development process of a product, we extended the idea of modelling standard life cycles as introduced by Block et al. [3]. This extension introduces the novel notion of undesired states within a product’s life cycle. Undesired states can be dissolved with the help of circularity measures. A Model Based Systems Engineering (MBSE) approach was developed to implement this strategy. The resultant modelling approach is implemented in form of a software tool. The system is evaluated within an automotive development project revealing a significant advantage in contrast to previous methods.
