What do we do? Methods, techniques and tools for efficient construction of reliable software by increasing support for abstraction, automation, and analysis Model-Driven Development (MDD): A software development approach in which models, rather than code form the primary artifact analyze Requirements create Models generate Software transform 2

A Historical Perspective 40 years ago: Requirements Hard ware Today: Requirements Hard ware Or, more technically: [Source: B. Selic] 3

Our Current Projects Theme 1: UML-RT • Formal semantics M : UML-RT ! pi-calculus ° “What does a model mean? ” • Execution, simulation, and correctness analysis M ² ? ° “Does the model do the right thing? ” ° using kiltera & model checking ° using symbolic execution Interfaces S, S • PSM conformance checking ° “Is it safe to compose two models? ” C 1 C 2 C 1 conforms to S? Components • Incremental test case generation ° “Making test case generation more efficient in the presence of model evolution” M 1 TC 1 covered by ? update M 2 TC 2 covered by 4

Our Current Projects (Cont’d) Theme 2: Model Transformation • MT case studies ° UML-RT to kiltera translation ° GM metamodel migration • MT and analysis ° “How do MTs affect model analysis? ” ° Core idea: q Domain/task-specific model transformation languages q Trade expressiveness for analyzability • MT for code generation M 1 t M 2 ² ? ² t preserves ? ° accurate code from timed models 5

Our Current Projects (Cont’d) Theme 3: Control Theory (CT) for SW Development • “Can large body of knowledge on CT be leveraged for solving SE problems? ” • Yes, e. g. , automatic generation of concurrency control code concurrent code + ? ² CT 6

Topics § (Design of) (domain-specific) model transformation languages • which “properties” (capabilities) does a MT language need to have to be fit for a certain class of MT tasks? • which “properties” (capabilities) can be removed to facilitate reasoning about MTs? § Analysis of model transformations • “The success of a language depends on its underlying theory” [JD] ° How can the design of domain-specific MT languages support reasoning? q c. f. , “correctness (e. g. , property preservation/establishment) by construction” • “The success of a language depends on its supporting tooling” [Bran Selic] ° How can the generation of this tooling be facilitated? q c. f. , language workbenches/frameworks/product lines (e. g. , van den Brand et al. , Atlee & Day) § Specification of model transformations • “A program without a specification can never be correct, it can only be surprising” [? ] § Analysis of models • correctness, conformance, MBT, … 7

Criteria of Success § I’m flexible… 8

We have a workshop, too… Analysis of Model Transformations (AMT) • at MODELS’ 12 • first in a long series? 9
