Open Source[edit]

Name Language Type Last Updated License Description
adevs C++ Library February 20, 2014 (v2.8.1)[1] BSD A C++ library for building discrete event simulations. Adevs is based on the Discrete Event System Specification (DEVS) and Dynamic DEVS modeling formalisms; it supports parallel discrete event simulation and a runtime system for OpenModelica.
CPN Tools BETA Software September 1, 2013 (v4.0.0)[2] GPLv2 A tool to analyse logistics/queuing models in all types of applications.
DESMO-J Java Library March 26, 2014 (v2.4.1)[3] Apache 2.0 A framework for discrete-event simulation in Java, supporting hybrid event/process models and providing animation in 2D and 3D.
Facsimile Scala Library April 29, 2009[4] LGPLv3 A free, open-source discrete-event simulation/emulation library.
Galatea Java November 4, 2013 (V3.0r6)[5] GPLv2 An agent-based simulation platform.
PowerDEVS C++ Software September 18, 2013 (v933)[6] AFL, GPLv2 An integrated tool for hybrid systems modeling and simulation based on the DEVS formalism.

SIM.JS JavaScript Library January 16, 2012 (v0.26)[8] LGPL SIM.JS is a general-purpose Discrete Event Simulation library written entirely in JavaScript. Runs in browser and a GUI-based modeling tool is supported.
SimPy Python Library April 7, 2014 (v3.0.4)[9] MIT An open source process-oriented discrete event simulation package implemented in Python. It is based on Simula concepts, but goes significantly beyond Simula in its synchronization constructs.
SystemC C++ Library March 23, 2014 (v2.3.1)[10] SystemC Open Source License A set of C++ classes and macros which provide an event-driven simulation kernel in C++.
Tortuga Java Library September 1, 2008[11] LGPLv2.1 An open source software framework for discrete-event simulation in Java.


  • AnyLogic is a graphical general purpose simulation tool which supports discrete event, system dynamics and agent-based modeling approaches. In discrete event simulation it roots to the same approach as GPSS, but provides additional features: combining different modeling approaches, dynamic animation, GIS integration (tile maps and shapefiles), DB-connectivity, DXF-import, rich experimental framework etc. Has a free PLE version available for educational and self-educational purposes.
