From State-Transition Models to DEVS Models - Improving DEVS external interoperability using MetaDEVS: a MDE approach: Improving DEVS external interoperability using MetaDEVS: a MDE approach

International audienceIn this paper, the issue of the “external” interoperability of DEVS models is discussed. Scientists often need to simulate non-DEVS models using a DEVS-oriented framework, in order, for instance, to make their DEVS and non-DEVS modes interoperate. The source formalisms we propose to transform onto DEVS models are those which are based on the “family” of states and transitions. A general and model-oriented approach called MetaDEVS is presented in this article. MetaDEVS is also the name given to the DEVS metamodel we use. This metamodel allows creating platform-independent DEVS models. This paper shows how models which belong to the state and transitions “family” can be mapped onto DEVS, and more exactly onto MetaDEVS-based DEVS models, following the MetaDEVS approach. Then, the approach is applied to a concrete case: we transform Finite-State Machine (FSM) models into MetaDEVS models, usingATL, a hybrid language (which mixes both declarative and imperative rules), within the Eclipse Modelling Framework. A metamodel to describe the FSM formalism is also proposed

Toward composing variable structure models and their interfaces: a case of intensional coupling definitions

In this thesis, we investigate a combination of traditional component-based and variable structure modeling. The focus is on a structural consistent specification of couplings in modular, hierarchical models with a variable structure. For this, we exploitintensional definitions, as known from logic, and introduce a novel intensional coupling definition, which allows a concise yet expressive specification of complex communication and interaction patterns in static as well as variable structure models, without the need to worryabout structural consistency.In der Arbeit untersuchen wir ein Zusammenbringen von klassischer komponenten-basierter und variabler Strukturmodellierung. Der Fokus liegt dabei auf der Spezifikation von strukturkonsistenten Kopplungen in modular-hierarchischen Modellen mit einer variablen Struktur. Dafür nutzen wir intensionale Definitionen, wie sie aus der Logik bekannt sind, und führen ein neuartiges Konzept von intensionalen Kopplungen ein, welches kompakte gleichzeitig ausdrucksstarke Spezifikationen von komplexen Kommunikations- und Interaktionsmuster in statischen und variablen Strukturmodellen erlaubt
