Generic approach for systems design optimization in MBSE

Abstract

The complexity of contemporary systems causes Systems Engineers great pains during early architectural design phases. Model-Based Systems Engineering (MBSE) proposes methodologies to deal with complexity and streamline design processes, but the penetration of the new approach is slow. This paper proposes a generic SysML based methodology for improving the Architectural Design phase of Systems and mitigate the barriers for MBSE adoption. The proposed methodology suggests an alternative way to formalize requirements, define design alternatives, automate design space exploration and examine optimization results in the original modeling format. A representative example is provided. A glossary is included at the end of the paper.copy;2012 by IBM.
