Introduction

In this section you will get some background information on UML and SysML. The following subjects will be covered:

• The history of UML and SysML – Overview on the SysML – How SysML extends UML – Overview on system engineering process.

Structure Diagrams

In this section you will learn how system structure, hierarchy and composition can be modeled using SysML. We will present the following diagrams:

• Block Definition diagram – Internal Block Diagram – Package Diagram – Parametric Diagram – Requirement Diagram.

Behavior Diagrams

In this section you will learn how functional requirements, system and subsystem dynamics can be modeled using SysML. We will present the following diagrams:

• Use Case Diagram – Activity Diagram – State Machine Diagram – Sequence Diagram.

System Engineering Process

In this section we will present a process of how to apply the SysML in real life system engineering process. The proposed process is based on a middle out iterative process creating a seamless transition between the system and subsystem level. We will cover the following topics:

Requirements Capture

• Developing and documenting the vision and system domain – Capturing functional and supplementary requirements.

Analysis

• Describing a conceptual system solution – effective use block definition, sequence and state chart diagrams – Demonstrating how requirements are realized based on the proposed structure.

• Creating system hierarchy and/or independent and reusable system blocks – Modeling physical structure – Preparing the requirements for the next level – Modeling traceability.
