Model-based risk-oriented robust systems design with object-process methodology

International Journal of Strategic Engineering Asset Management (IJSEAM), Vol. 1, No. 4, 2013

Abstract: We introduce and demonstrate ROSE - risk-oriented systems engineering, a new approach that integrates risk aspects with system analysis, modelling and design. ROSE is designed to improve the integration and coordination of system design and risk management by fusing robust design paradigms with risk analytic techniques in a model-based environment. While system design and risk management are two critical systems engineering processes, their integration is loose, because too often systems engineers and risk analysts use different semantics, techniques, and tools. This unfortunate disconnects renders risk management efforts detached from system design and management. Object-process methodology (OPM) is a bimodal visual and textual conceptual modelling language and an emerging ISO Standard (19450) for system modelling and design. Making use of OPM, ROSE integrates risk identification, modelling, analysis, mitigation, and control aspects into the robust system design process, and later into system deployment, configuration, and management. Using a commercial airliners defence system against shoulder missiles as a case in point, we demonstrate the principles and benefits of ROSE in risk-oriented systems.
