Time-dependent prediction of effort needed for engineering changes

This paper presents an approach for predicting change efforts for planning the production of a component under development. The change effort is characterized by the duration of implementation and the respective costs. Unlike existing methods for change impact analyses, this method enables an automated change impact prediction at any point in time within the product development process, since change impact differs with temporal distance to the start of production. The method was developed for the automotive industry and delivers a valid basis for increasing flexibility with a view to production system changes. © 2021, VDI Fachmedien GmBbH & Co..
