About Webel

in

Webel - in operation in Australia since 2000 - is a Scientific IT Consultancy, specialising in model-driven software engineering and systems engineering for tasks in science and engineering using technologies such as:

Graphical Unified Modeling Language (UML)TM & Systems Modeling Language (SysML).
Advanced domain- and systems-analysis using Dr Darren's UMLTM Parsing Analysis recipe.
Object-oriented JavaTM and C++ (always under UMLTM-driven development of course).
Extensible Markup Language (XML), including graphical and generative XML Schema design.
Real-time signal processing and audio and video synthesis technologies.

Webel offers services in analysis, design, architecture, modelling, simulation, animation, web application and & desktop application development, and custom data analysis. And Webel also develops database-driven Content Management System (CMS) web sites powered by Drupal (like this site).

The Webel newsletter: inaugural quarterly edition gives a good overview of services and technologies offered by Webel.

Proprietor Dr Darren welcomes you to Webel - the "Elements of the Web"

A hands-on Webel IT course and workshop held over 5-days.

Contents of: Course: Practical systems engineering with the OMG's Systems Modeling Language (SysML) and the MD SysML Plugin for MagicDraw UML.

Day 1 | Overview of UML2 and SysML for systems engineering | MagicDraw UML and the MD SysML Plugin |

Overview of UML2+ and SysML1+ for systems engineering

Why graphical, associative, port-based, and patch-based "synthesis engineering" is (potentially) so powerful.

What UML is and how and why it has been traditionally used “just” for software engineering.

Dr Darren's SysML Block reference "poster"

Overview of the SysML Diagrams (and the UML Diagrams they are adapted from).

Some example systems used in this course:

Group demonstration of Wii remote version with wireless Bluetooth telemetry

Aspects of UML2 useful for systems engineering, and how SysML builds on them

UML StructuredClassifier

UML Ports, Connectors, and the EncapulatedClassifier

UML2 Port

A Port may provide and/or require Interfaces

MD UML: Using a Class with Ports in a higher level system

Architectural “Dependency wiring” of Interface contracts in MagicDraw UML

UML InformationFlows for conveying information.

UML2 InformationFlows in MagicDraw UML

UML DataTypes as conveyed data tokens

Power features of MagicDraw UML and the MD SysML Plugin

UML2 (and the UML specifications) vs. MagicDraw UML vs. MD SysML

A serious limitation of InstancesSpecifications for systems engineering: no Ports !

Day 2 | SysML: history, specification, metamodel | structure, flow, quantity, value, configuration, context, time, space |

The SysML Block: an extension of the UML Class

FAQ: Why does the classifier-level Block stereotype show on parts in an IBD ?

SysML Port and FlowPort

Example: compartment display of Ports: Class vs. Component

Representing physical, industrial, and financial quantities in SysML

Example: a Structured ValueType

Representing value state and modes of complex systems in SysML

Block definitions for PropertySpecificTypes as instance value carriers

Progressive initialisation of value state using the UML2 Property.defaultValue (in SysML1.1 "initial values")

[Advanced] Example: initialise value at a Port

Example: Use a Battery

Why UML2 InstanceSpecifications can't be used generally for SysML "instance/object views"

Mathematical Constraints analysis in SysML

Day 3 | Behavior, State, Requirements, Allocation | Process Management, Project Management, Human Management |

Modelling Behavior and State in SysML

SysML extends UML2 Activities and Activity Diagrams

Why you should always (and I really mean always) use explicit Pins on Activities

What's wrong with the UML2 ObjectNode (and every UML2 compliant tool)

Live demo: representing States of the participant's case study problem.

Use Cases in SysML

SysML1.0 introduces no additional Use Case stereotypes beyond UML2.

Using SysML Requirements

Using SysML for Project Management

Combining SysML with your favourite systems engineering process

Using Stereotypes to carry project metadata

Tracking human resources and working groups using Actors

Generating model reports using MagicDraw UML and MD SysML

Day 4 | SysML review, MD SysML tips, fun examples, questions | The UML- and SysML Parsing analysis recipes |

More TIPS for using SysML in MD SysML

Exploit the powerful hyperlinking and diagram icon facilities of MagicDraw for easy cross-navigation between elements, packages, models and diagrams

Watch out for module Dependencies !

Really very tricky MagicDraw UML tricks

SysML Review and Question time

The UML- and SysML Parsing Analysis recipes for sentence-by-sentence systems engineering

From engineering documents in natural language to understandable SysML models.

The «realizations» compartment

Tracing manually created Dependencies FROM «wrapper» Components TO analysis elements

HOWTO separate parsing analysis elements and «source» text «wrapper» Components in Models from systems elements in Packages

Protecting modularisation: On the issue of Relationships from packaged systems elements to source text wrapper Components in "focus diagrams"

Day 5 | Workshops | SysML Parsing Analysis of your own technical document into SysML models | Team presentations, group discussion |

Workshop | morning | SysML Parsing Analysis of a document of your choice in MD SysML |

Workshop | afternoon | team presentations followed by discussions of each team's SysML models | conclusion |
