Identification of Unintended Effects Caused by Adaptations of Manufacturing Process Sequences for Safety-Critical Components

摘要

Changes of components are inevitable for companies to maintain competitiveness. To implement component changes, the manufacturing has to be adapted as well. For safety-critical components, unintended effects caused by adaptations pose a challenge due to the required reliability to ensure the component’s functionality. Therefore, a methodology to identify unintended effects of manufacturing adaptations is introduced and applied to a case study. Interdependencies within manufacturing are modeled through a multiple domain matrix and the model is extended by unintended effects within single manufacturing processes. Graph theory is further used to analyze the propagation of the instigating change within the manufacturing system.
