OMG is celebrating the 15th anniversary of the adoption of the Unified Modeling Language (UML) as an official OMG specification: CONGRATULATION!
Like all officially adopted OMG specifications, UML is available for free download from the OMG website. UML is also formally published as an ISO/IEC Standard.
In an effort to organize, simplify, and provide a way to enable interoperability of nearly fifty different object-oriented modeling approaches, on June 6, 1996, the OMG established an Object Analysis and Design Task Force (OA&D TF), which issued a request for proposal to create what would become UML.
In response, nineteen companies formed six teams, each producing competing proposals. Over the coming months, the teams worked together and consolidated their effortsinto a single proposal for a Unified Modeling Language (UML) submission. By unanimous vote on 25 September 1997, the UML submission was recommended for adoption by the OMG’s OA&D Task Force.
Today, UML is used to model structure and behavior of every type of software from enterprise automation to real-time embedded systems. UML is flexible enough to be used for everything from initial concept designs through full code generation.

The picture shall provide roughly overview of Enterprise Architect layer architecture. Most important message: The EA itself is built of building blocks and it can be flexibly extended more or less in the same way (like AMUSE it does). The only difference between self made MDG Technologies / Add-Ins and EA original functionality – there are some APIs reserved for EA internal usage.
MDG technologies shall be used for extension of already available technologies like UML or SysML by providing new tool boxes, stereotypes, tagged values etc.
Add-Ins shall be used for providing completely new functionality like new UIs, diagram types, reports, supporting of user workflows etc.

Good news for all Enterprise Architect and AMUSE users – finally we got proved numbers! The following dissertation shows why it’s true why the benefits definitely overweighs the costs and why MBSE (Model Based System Engineering) is the approach of the future development.
The only question keeps open – how to use Enterprise Architect and AMUSE to get maximum benefit of these tools, e.g.
The answer is – yes you can! But it’s a stuff for one of the next articles

In the course of the project MOLIZ, a research project together with the Vienna University of Technology, we kindly invite you to participate in an online survey about the usage of models in practice and requirements for model execution.
The questionnaire is targeted at people who work with models and especially at people who use UML or UML profiles, such as SysML. Filling in the questionnaire will take only approximately 15 minutes. We kindly ask you to take that time and thereby significantly support research in the area of model execution. The results of the survey will be published.

This standard defines the precise execution semantics of a foundational subset of UML 2 that includes a subset of UML class diagrams and activity diagrams. Hence, the fUML standard is highly related to AM|USE.
My master’s thesis is concerned with this new standard. The thesis is online available at http://publik.tuwien.ac.at/files/PubDat_196765.pdf. In course of my research activities at the Vienna University of Technology I am currently implementing an AM|USE extension that enables the execution of activity diagrams compliant to the execution semantics defined in OMG’s fUML standard.

It’s a kind of “Hello World” for multiple machines, simplest possible example
Two state machines fires triggers to each other: Ping fires ping trigger and receives pong trigger and pong works another way around.
1. Download XMI
2. Create an empty Enterprise Architect project
3. Import XMI
4. Open ping and pong state machine diagrams
5. Add both to AMUSE simulation window
6. Start pong first then ping
7. if initial ping wasn’t caught, fire first trigger manually via trigger menu
8. watch the ping/pong counters

Today i will give you some extra information.
It is also possible to start the executable which is deployed on the mobile device as standalone application/statemachine.
When starting the application (either on the mobile or on the pc), without using Enterprise Architect, the statemachine will be executed within the application.
After starting the workflow in Enterprise Architect, you will find the executable in “C:\tmp\simulation\someautogeneratednumber”. You can use this executable as standalone application and it works.

The goal of this entry is to show how a flight booking process with different web services and a mock-up GUI can be simulated and verified with AMUSE. The focus is on the orchestration of the web services, which are part of the flight booking process. In a next step it would be interesting to generate BEPEL out this state machine.
The flight booking process
The user of an online travel agency calls the appropriate website and enters his flight details on that page. Then a search for possible flights, hotels and events taking place during the stay starts, which calls different web services. The Results are then finally displayed on the site.
This simple process is modeled in the following activity diagram:
Mock-up GUI
This GUI is used to feed the simulation with the user rel="lightbox[2378]">
EventService: Implements the method EventList, which displays all available events at a given time. In this example, every time the same events are described. It is enough for the demo.
[WebMethod]
public string EventList()
{
return “International film festival \n Rock konzerte \n Music festival”;
}
FlightService: Implements the method FlightInfo, which displays the flights available from one location to another at a given time.
[WebMethod]
public string FlightInfo(string from, string to, DateTime departureDate,DateTime returnDate)
{
return from.ToUpper() + “–” + to.ToUpper() + ” HG8010 ” + departureDate + ” 08:15 \n” +to.ToUpper()+””+from.ToUpper()+” HG8011 “+returnDate+” 11:55 \n —————————————————– \n Rate:200€”;
}
HotelService: The method HotelInfo displays all available hotels during the stay
[WebMethod]
public string HotelInfo()
{
return ” Grand Hotel(4 Stars) \n Rate per night 59€”;
}
InputValidationService: The method ValidateInput target="_blank">Simons post .
The flight booking process modeled as a state machine
