An MBSE Approach to Pass from Requirements to Functional Architecture

With systems being more and more complex, especially in the case of Nuclear Power Plant design, Systems Engineering (SE) has seen an increasing interest in the industrial world. Although SE concepts and processes have become well-known, passing from Requirements to Functional Architectures has not been a fully addressed issue. This paper proposes a tooled method that offers three different design perspectives: a Requirement View, a Context View and a Behavioural View. Those views mainly help the designers to express requirements, structure their architecture design, work together, verify and partially validate their design by means of five interconnected Design Specific Modelling Languages (DSML).
