“…HLA has a standard development process called the Federation development and execution process (FEDEP) which is not designed to be compatible with MDA or the Model-Driven Integration (MDI). This section presents the outline of a methodology for the development of complex simulation applications where automatic generation can not fulfil the requirements [32][33]. The methodology aims to support the combined use of FEDEP and MDA.…”

. A model-driven approach to multidisciplinary collaborative simulation for virtual product development. Advanced Engineering Informatics, Elsevier, 2010, 24 (2) Abstract:The design and development of complex artifacts and systems is shifting towards a distributed and collaborative paradigm. The simulation environments for such a paradigm, therefore, need to take into account the cooperation between design teams, i.e. supporting multidisciplinary simulation in a distributed environment. However, current simulation tools cannot fulfil this requirement as they have been developed to solve the specific problems from different disciplines. Although it's already possible to per-form multidisciplinary simulations by using several tools together, it is very difficult to implement it when these tools are distributed on the Internet. A solution which can support the integration of distributed simulation models at run-time is presented, involving a computational infrastructure and a high-level modelling approach. Specifically, the infrastructure is constructed by a novel combination of two distributed computing techniques to implement the synchronization of distributed models, as well as to ensure the interoperability at run-time. In addition, a model-driven approach is developed to bridge the high-level model of a simulation system and the infrastructure which implements this model. The solution is evaluated by making a comparison with other approaches, as well as by developing a prototype tool. It's shown in the evaluation that (1) it is viable to develop multidisciplinary simulations in a distributed environment using this solution; (2) the model-driven approach allows designers to focus only on the high-level structure of a design without getting concerned with the details of the infrastructure.

DEVS is a formalism intended to model bothdiscrete and continuous systems. The use of discrete events, rather than time steps, as the basis for simulation has been shown to reduce the computation time in many applications. Parallel DEVS is an extension to standard DEVS, which provides means to handle simultaneous scheduling. In this paper, we present an implementation of the parallel DEVS simulation protocol that uses a modified Time Warp optimistic algorithm for shared memory multiprocessor machine. This implementation is designed to execute the DEVS models in parallel and, at the same time to correctly simulate every model defined in terms of DEVS specification. Two test cases and the DEVSFIRE example are used to verify this algorithm. Preliminary experimental results are presented that show the implementation can speedup a DEVS simulation.

International audienceThis paper presents a simulation environment for manufacturing systems integrating control processes and operational processes. From the operational processes specification according to the JIS Z 8206 norm and from the control processes as Workflows standards, distributed G-DEVS models are generated. At first, the transformation of a process in G-DEVS models is described. Then, the implementation of a global simulation of the set of these models via an HLA architecture allowing interconnection and interoperability between the model components is presented. An illustration of the use of this environment is given in the microelectronic field. We conclude by the application of this approach to the study of the synchronizations between production lines and to the implementation of coupling between simulation and reality
