Towards the Systems Requirement Modeling With a Single Language

In the field of engineering, the design process frequently involves numerous graphical formats, lacking a unified standard. The Object Management Group (OMG) introduced SysML to model system requirements and their interrelationships with other modeling elements; however, SysML primarily addresses functional and non-functional requirements, disregarding the modeling of decision requirements prevalent in numerous systems. Conversely, the OMG also proposes the Decision Model and Notation (DMN) standard for modeling decision requirements. This paper proposes the use of SysML as a unified language for modeling various types of requirements, with a particular focus on decision requirements. To achieve this, we present a model-to-model transformation using Query/View/Transformation to transform a DMN requirement model to the SysML requirement model.
