Training on SysML

🗓 Day 1 — Foundations & Structure

Objectives: Learn MBSE concepts, SysML basics, and structural modeling.

Topics

• MBSE overview, V-Model, benefits.

• SysML basics: packages, blocks, relationships.

• Block Definition Diagram (BDD) & Internal Block Diagram (IBD).

• Hands-on: model a simple system (Ex. System Control Unit → Sensors + Actuators).

Lab

• Create project shell in SysML tool (Rhapsody, Cameo, or EA).

• Draw BDD for SCU + subsystems (Comms, Control, Power).

• Add IBD showing connections (CAN, BLE, RS-485).

Deliverable: System structure (BDD + IBD).

🗓 Day 2 — Requirements & Behavior Basics

Objectives: Capture requirements and model simple behavior.

Topics

• Writing good requirements (INCOSE style).

• SysML requirement diagrams.

• Use Cases & Activity diagrams (functions & workflows).

• Intro to sequence diagrams for interactions.
  
  

Lab

• Write 5–10 requirements for SCU.

• Build Requirement diagram + trace to blocks.

• Create Activity diagram for "Commissioning Mode".

• Draw Sequence diagram: SCU requesting charge from BMS/DCDC.

Deliverable: Requirements + basic behavior model.

🗓 Day 3 — States, Modes & Architecture View

Objectives: Model operational states, tie architecture views together, and wrap up.

Topics

• SysML State Machine diagrams (modes, transitions).

• Architecture views (functional, physical, allocation).

• Lightweight verification & traceability.

• Best practices: naming, organization, documentation.

Lab

• Build State Machine for SCU: Normal / Commissioning / Maintenance.

• Show allocation: map functions to SCU components.

• Export simple model report (diagrams + requirement trace).

Deliverable: Small end-to-end SysML model of SCU with requirements, structure, behavior, and modes.
