UML1(.x)
● In industrial practice, UML models have been used primarily for problem understanding(i.e., analysis) and documentation
● Nevertheless, several tools supporting executable variants of UML
● These tools historically relied on custom semantics (profiles) in combination with traditional third-generation programming languages (e.g., C++ or Java) for specifying detailed action code

![Page 3: Execution of UML models · 2019-12-05 · UML1(.x) In industrial practice, UML models have been used primarily for problem understanding(i.e., analysis) and documentation Nevertheless,](https://reader033.vdocuments.net/reader033/viewer/2022043011/5fa5dc2a255597753d5b8f5d/html5/thumbnails/3.jpg)
Thereby..
● Tools not fully compliant with the UML standard
● (Industrial) end users forced into a potentially dangerous “vendor lock-in” predicament

The (r)evolution of UML2
● Semantically more precise than UML1 when it comes to execution aspects
● Provided with fUML, a formal specification of the executable semantics for a subset of UML2
● Provided with ALF, a textual action language based on fUML for compact and complete specification of complex behaviors including their algorithmic parts

So that..
UML models based on UML2, fUML and ALF are fully executable provided that corresponding methods and
tools are available

experimentation in industrial settings; among them, only a few rely on empirical evaluation

Our Perspectives for UML execution
● The results of our study tell us that the following should be given priority both by researchers and tool developers
● ability to execute abstract (high-level) and incomplete models
enhanced observability of executing models enhanced control of model execution directly compiled model executables support for UML-compliant action languages support for executing models based on UML profiles integration of UML simulators into heterogeneous (multi-paradigm) simulation systems use of model-reference approaches at runtime
