Transforming Systems Engineering through Model-Centric Engineering

Abstract : The vision held by NAVAIR's leadership is to assess technical feasibility of radical transformation through a more holistic model-centric engineering approach. The expected capability of such an approach would enable mission-based analysis and engineering that reduces the typical time by at least 25 percent from what is achieved today for large-scale air vehicle systems. Research tasks were: surveying industry, government and academia to understand the state-of the-art of a holistic, model-centric engineering, develop a common lexicon model-centric engineering, model the Airworthiness processes, and integrate a risk management framework. While research suggests that it is technically feasible to create a holistic approach for conceiving innovative concepts and solutions enabled through model-centricity. Operational transformation is needed to coordinate efforts across multiple disciplines and multiple stakeholders. Findings explored with NAVAIR are: growth, complexity, and development of software; interoperability, consistency, and limitations of transforming model semantics; and validation of models.
