Modeling & Simulation
Having the means to understand, define, and unambiguously communicate both system requirements and system solution (architecture) is imperative to build a quality system. Models and simulations provide some of these means and facilitate the understanding of several systems aspects such as structure, relations among systems elements, operational descriptions, states, events, and flows. Models can be used to provide a visual representation of the problem and/or system solution in artifacts produced in mission analysis, stakeholder requirements, system requirements, architecture, and design. Models and simulations are used throughout the system lifecycle to support systems analysis, verification, and validation.

The Systems Modeling Language (SysML)
Modern systems modeling involves the specification of the system architecture using graphical modeling diagrams. Without set standards in the syntax and semantics of such diagrams, it is very challenging to share unambiguous understanding of the system architecture with customers, teammates, partner organizations, and other stakeholders around the world. Since 2006, the Object Management Group (OMG) has published the Systems Modeling Language (SysML) Standard, which defines the syntax and semantics of the language so that all users are employing consistent usage of the language to construct system architecture descriptions.
The OMG has defined nine diagrams in the SysML:
- Block Definition Diagram
- Internal Block Diagram
- Use Case Diagram
- Activity Diagram
- Sequence Diagram
- State Machine Diagram
- Parametric Diagram
- Requirements Diagram
- Package Diagram
This section provides lecture material that covers the nine SysML diagrams and related topics.
