COST-BENEFIT ANALYSIS IN MODEL-BASED SYSTEMS ENGINEERING: STATE OF THE ART AND FUTURE POTENTIALS

The increasing complexity and shorter time-to-market cycles demands enhancement methods for conceptual design phases. An instrument to promote product development activities by enlarging document-based methods on system level via increasing modeling effort is Model-Based Systems Engineering (MBSE). The intention of shifting this effort into early phases by frontloading-concepts on the one hand should reduce costs in the series development on the other. The resulting cost-benefit coherences of these correlations on system level as a symbiosis of mechanical-, electrical-and software engineering is currently a small highlighted research topic. Therefore, the paper analyzes the recent state of the art by evaluating industrial cost-benefit-theories in MBSE. The summary of existing industrial studies and indicators transferred to thereof resulting cost-benefit models consolidates a lack of research regarding the product system level. An initial approach to create new indicators, based on recorded expert interviews, for the development of an industrial MBSE benefit-model regarding costs is focussed after this summary. For this model, a MBSE pilot project in industry is discussed
