REimagined: A Domain-Specific Language for Model-Based Requirements Engineering

As cyber-physical systems (CPS) are becoming increasingly complex, the need for robust requirements engineering becomes apparent. Model-based requirements engineering (MBRE) is an essential approach that can help to establish traceability between requirements and system components. However, current approaches, such as the SysML requirements diagram only support modeling the formalized requirements and fail to depict the process leading up to those requirements. The process of stakeholder analysis, requirements elicitation, including the identification of stakeholder needs, is not supported in current requirements modeling approaches. To close this gap, this research presents a domain-specific language (DSL), implemented as a Unified Modeling Language (UML) profile for Enterprise Architect (EA). The proposed DSL allows for modeling the entire RE process as it is defined by the International Requirements Engineering Board (IREB), from stakeholder analysis to system validation, ensuring traceability across all phases.
