Methode zur Bewertung von Anforderungsänderungen additiv gefertigter Produkte

In this paper, a novel approach towards risk classification of requirements of additively manufactured (AM) products is presented. The classification of an individual requirement is based on two aspects: a) influence factors implying dynamics of its specification and b) network indices quantifying the degree of cross-linkage with other requirements. Both aspects can indicate requirement changes. Influences on a requirement are assessed by a priority index based on criteria ‘uncertainty’, ‘dynamics’ and ‘relevance for product development’. Effects from other requirements are captured by network theoretical indices such as active and passive sum. In the end, requirements are classified accord-ing to their criticality. By this approach, requirements can be identified which might strongly affect the product development process of AM products.
