Discrete EVent Systems Specification (DEVS) formalism supports specification of discrete event models in a hierarchical modular manner. This paper proposes a DEVS modeling language called DEVS Specification Language (DEVSpecL) based on which discrete event systems are modeled, simulated and analyzed within a DEVS-based framework for seamless systems design. Models specified in DEVSpecL can be t...

Recently, a new approach for structuring acyclic process models has been introduced. The algorithm is based on a transformation between the Refined Process Structure Tree (RPST) of a control flow graph and the Modular Decomposition Tree (MDT) of ordering relations. In this paper, an extension of the algorithm is presented that allows to partially structure process models in the case when a proc...

This paper introduces a modular modeling approach for distributed production systems, considering production and maintenance processes synchronization. Thus, production job shop, preventive and curative specialized telemaintenance actions are studied together. Stochastic synchronized Petri nets are used for modeling. This tool was adapted to the tele/maintenance distributed case and to integrat...

The work in this paper1 is devoted to the definition of a dependability modeling and model based evaluation approach based on UML models. It is to be used in the early phases of the system design to capture system dependability attributes like reliability and availability, thus providing guidelines for the choice among different architectural and design solutions. We show how structural UML dia...

When different parts of a system depend on different technical domains, the best suitable paradigm for modeling each part may differ. In this paper, we focus on the semantic adaptation between parts of a model which use different modeling paradigms in the context of model composition. We show how CCSL, a language for defining constraints and relations on clocks, can be used to define this seman...

Ptolemy is an open-source and extensible modeling and simulation framework. It offers heterogeneous modeling capabilities by allowing different models of computation to be composed hierarchically in an arbitrary fashion. This paper describes modal models, which allow to hierarchically compose finite-state machines with other models of computation, both untimed and timed. The semantics of modal ...
