SysML extends UML2 with new modeling concepts and diagrams for systems engineering. It also identifies the parts of UML2 that are relevant for systems engineering modeling. The new concepts concerns requirements, structural modeling, and behavioral constructs. New diagrams include requirement diagram and parametric diagram, and adjustments of activity, class, and composite structure diagrams. Tabular representations of requirements or allocations, for example, are also included as an alternative notation.

Requirement diagrams are used to define a classification of requirements categories (e.g., functional, interface, performance) or a hierarchy of requirements, describing the refinement relationships among requirements in a specification. Requirement relationships include DeriveReqt, Satisfy, Verify, Refine, Trace, and Copy. An example of requirement diagram is shown in Figure 9.33.

The Requirement Diagram of SysML or other professional requirements management tool, such as IBM Rational DOORS, is used to construct the DCS requirement model, and then catch stakeholder’s requirements and translate them into system requirements. Next, system use cases are defined and assigned system requirements through Use Case Diagram of SysML. For ease of analysis, we only focus on firefighting use case and its realisation in this section, as shown in Figure 12.
