An important class of ecological problems concerns propagation processes. In ecological modelling, these phenomena generally occur on large scales and are generally difficult to simulate efficiently because of the number of entities. Studies of this kind of phenomena lack genericity and reusability because they are often presented from the point of view of(More)
Design tools can be profitably associated with libraries of reusable modeling components that will make the description and also the validation of the models much easier. Furthermore, applications of today and tomorrow will be increasingly based on three fundamental technologies: Object Orientation, Client/Server and Internet. We propose in this article an(More)
The fire spreading phenomenon is highly complex, and existing mathematical models of fire are so complex themselves, that any possibility of analytical solution is precluded. Instead, there has been some success when studying fire spread by means of simulation. However, precise and reliable mathematical models are still under development. They require(More)
Studying complex propagation phenomena is usually performed through cellular simulation models. Usually cellular models are specific cellular automata developed by non-computer specialists. We attempt to present here a mathematical specification of a new kind of CA. The latter allows to soundly specify cellular models using a discrete time base, avoiding(More)
This paper presents a simulation performance improvementof the application of the Multicomponent Discrete TimeSystem Specification (MultiDTSS) formalism to a firespread. Multicomponent choice is explained through bothMulticomponent systems and networks of systems criticalstudy for cell spaces modeling and simulation. A new functionhas been appended to the(More)
—The Modeling and Simulation (M&S) of complex systems leans on the collaboration between different actors coming from specific domains. These actors have to communicate through an efficient software in order to improve the M&S process. We therefore propose in this article a collaborative M&S software framework called DEVSimPY. We point out the use of(More)
Along with a continuously growing number of publicly available Web services (WS), we are witnessing a rapid development in semantic-related web technologies, which lead to the apparition of semantically described WS. In this work, we perform a comparative analysis of the syntactic and semantic approaches used to describe WS, from a complex network(More)
Validation of VHDL descriptions at the early phases of the microelectronic design is one of the most time consuming task design. This paper presents a test vector generation method for behavioral VHDL design. This method analyzes control and dependence flow of VHDL program. We use the cyclomatic complexity, that is a software metric based on a graph(More)
The paper deals with test automation of GUI (General User Interface) software using simulations. The development of GUI software requires a great amount of time and cost concerning the testing aspects. In order to facilitate and speed up the testing of such GUI software an approach based on discrete-event modeling and simulation is proposed. Traditionally,(More)
We present the use of the CD++ tool to model and simulate forest fire-spread. A semi-physical fire spread model is implemented using the Cell-DEVS formalism. The use of Cell-DEVS enables proving the correctness of the simulation engines and permits to model the problem even by a non-computer science specialist. The high level language of CD++ reduces the(More)
