VLE is a multi-modeling and simulation environment to study complex dynamic systems. VLE is based on the discrete event specification DEVS. and it implements the DSDE formalism (A merge of Dynamic Structure DEVS, DSDEVS, with Parallel DEVS, PDEVS). VLE provides a complete set of C++ libraries, called VFL (VLE Foundation Libraries), to develop DEVS models, to gets results of simulations, to launch simulation on cluster. The models can be developed with the DEVS formalism or with the classical mathematical formalism: Ordinary Differential Equation with Euler, Range-Kutta or QSS integrator, Finite state automaton (FDDEVS, UML State chart, Hybrid Petri net). The VLE environment provides an IDE to develop C++ models, DEVS coupled models. VLE have also three ports to use the VFL with Python, Java and R programming languages.
- Discrete event modelling and simulation
- DEVS (Discrete Event System Specification)
- Graphical modelling IDE
- C++ API libraries development
- Extensible platform via plug-ins
- KISS programming method
VLE is a very good simulator with several extensions (such as Petri Nets, UML-like statecharts ...). It simplifies the modeler's tasks throuh these extensions and makes possible to easily create heterogeneous models.
