Model-based Risk Analysis & Mitigation using UAFP and Cameo Safety and Reliability Analyzer
This paper describes how the combination of multiple UML profiles and information types from various Risk Analysis methods supports the vision of MBSE and ensures that Risk Analysis & Mitigation is addressed in the same model as the system architecture. Forming this single Model-based Risk Analysis & Mitigation (MB-RAM) Conceptual Model enables the system engineers to apply a formalized model-based risk method to expose the quantitative measures and mitigation mechanisms required to minimize the potential impact of identified risks. The MB-RAM Conceptual Model augments multiple UML profiles (i.e., UAFP, Safety Profile, Operational Threat and Risk Profile, Semantic Information Modeling for Federation) with additional risk-related information elements to bring forward awareness of risks that may impact critical assets. Practical application of MB-RAM Conceptual Model is demonstrated using Cameo Enterprise Architecture v19 and the Safety and Reliability Plugin.
