The Virtual Laboratory Environment is a multi-modeling and simulation platform. It is a powerful modeler and simulator supporting the use of different formalisms for models specification and simulation.

VLE is particularly well adapted for complex models where the coupling of different formalisms is required. In addition to the classical use of one single formalism for modeling and simulation, VLE can integrate, i.e. couple, heterogeneous formalisms in one coherent simulation model.

For instance, VLE supports, and is not limited to, the modeling and simulation of the following formalisms (stand alone or coupled together):

  • Discrete Event Specifications
  • Differential equations
  • Difference equations
  • Petri net
  • Finite State Automata

VLE supports the following modeling and simulation paradigms:

  • System Dynamics
  • Multi-Agent Systems, Multi-Agent Simulation
  • Decision support systems
  • Learning systems

VLE is based on the theory of modeling and simulation initially developed by B.P. Zeigler in the 70’s and continuously enriched until now by an active international community.

VLE is based on the DEVS formalism (Discrete Event systems Specification). VLE provides a set of C++ libraries, the VFL (VLE Foundation Libraries) and a lot of programs like a simulator, a graphical user interface to model and develop models and tools to analyze and visualize simulation outputs. The VFL are sufficiently well designed to allow the development of new simulators, models or new programs for modeling and analysis.

Our goal with VLE is to provide powerful tools for modeling, simulating and analysing complex dynamics systems. We hope build an easy to use software. Our development are complying with the DEVS specification DEVS and works made by the simulation community. We are also pursuing the objective to develop and maintain a community of users and developers using an open, agile and community oriented development.

VLE is a free environment of multi-modelling and simulation developed under the [licence GPL v3.0]. All source code are availabled on Github.
