REQUIREMENTS MANAGEMENT IN EARLY STAGES OF MECHATRONIC DESIGN BY VISUALISATION OF INTERDEPENDENCIES

Abstract

In this contribution, applications of a new Decision Making (DM) tool based on a qualitative modeling and visualization of interdependencies between requirements are shown and discussed. Concretely, DM tasks occuring when designing parallel robots are qualitatively modeled by a pairwise comparision of interactions between requirements. The resulting interaction matrix is the input model required by the visualization method. Based on that interaction matrix, the tool calculates and shows an easily understandable visualization of the entirety of all requirements based on their interactions in a three-dimensional space. Such visualization is shown for two DM tasks from different development stages in the field of parallel robots.
