Interface Management with Closed-Loop Systems Engineering (CLOSE)

Interfaces (IF) and their Management (IFM) are a particular challenge in the successful development of complex products and products operating in a complex environment. In Closed-Loop Systems Engineering (CLOSE) IFM is fully integrated into its Model-Driven Engineering Process (MDEP). CLOSE provides fully automated IF modelling, traceable IF history, an efficient handling of IF negotiations and the effective de-coupling of interfacing systems. Especially in combination with CLOSE's Experimentable Digital Twins (EDTs), IFM becomes a vital resource for the development process, rather than the parallel process it so often is today, supporting early variant evaluation, balance checks and impact analysis, which makes it a central asset for developing better products. This paper describes IFM in CLOSE and illustrates it with a case study of a Martian robot for autonomous scientific missions.
