Abstract

Various drivers, especially increasing market dynamics, force industrial enterprises to evolve their production facilities ever more frequently. Analyzing the impact of changed requirements on the production facilities early in the engineering process would facilitate the estimation of resulting costs and therefore reduce project risk. In industrial practice, requirements specifcations are typically textual lists and only structured by a table of contents; an analysis of the impact of changes within the requirements specifcation is extensive, as no documented information is available about how the requirements and other elements of the requirements specifcation depend on each other. To identify impacts of changes in a requirements specifcation more effciently, this paper proposes a model-based approach that classifes the elements of a requirements specifcation according to their contents and based on the classifcation preselects automatically candidate elements of the requirements specifcation that are possibly affected by the change. This paper shows the application of the approach on the manufacturing automation systems domain by means of a pick and place unit (PPU) demonstrator. The technical validation demonstrates that in the example of the PPU the impact analysis is more effcient with a content model than on an unstructured list; the effort for impact analysis is reduced further when adapting the content model to the manufacturing automation systems domain.
