Briefly said, PetriNetExec is an open-source Java library which allows you to embed Petri Nets into your Java application. Using PetriNetExec you can define places and transitions, connect them using arcs and inhibitors, define the initial marking and then fire events and see how tokens flow into the network. * PetriNetExec does not provide a GUI for editing the network nor will it provide in the near future. That is not really a feature :-) but to those of you able to cope with this news I suggest to read further; * Petri Nets are created with PetriNetExec by writing Java code and using the provided API; * PetriNetExec provides a simple yet powerful callback mechanism allowing you to actually do something when events are fired and the network status is changing. * PetriNetExec is embeddable into your Java application. This means that you can build your own application and add Petri Nets into it. * PetriNetExec is open-source.

The Pi Markup Language (PiML) aims at providing an XML based representation format for the description of models encoded in the Pi Calculus. The XML representation of such Pi Calculus models should support model storage, exchange, and coupling.

QPME (Queueing Petri net Modeling Environment) is a performance modeling and analysis tool based on the Queueing Petri Net (QPN) modeling formalism.

RPowerFlow - a steady state electric power system power flow solver.

Recito is a graphical modeling and process simulation platform.

The Gateways Team of the Live-Virtual-Constructive Architecture Roadmap Implementation (LVCAR-I) effort is developing a set of tools that will support the gateway community. One of these tools is the Simulation Data Exchange Model (SDEM) Mapping Language (SML) Editor. The tool provides the ability to import two SDEMs in their native language and subsequently view the entities that need to be mapped between the two SDEMs. The SDEM Editor also allows the user to create these mappings and store the result in an SML file.

Software Process Model Suite is a toolset for modeling and simulate software process models. Is composed by: 1. a simulator engine; 2. a modeling tool based on SPEM, that uses model transformation approach; 3. a visual graphical simulator.

SPSens is a complete software package written in C that estimates parameter sensitivities for stochastic models of chemical and biochemical reaction networks using Monte Carlo (MC) stochastic simulations. It is possible to estimate sensitivities with respect to system parameters using the following algorithms: finite difference methods (crude monte carlo, common reaction path, coupled finite differences); likelihood ratio methods; and regularized pathwise derivatives. Additionally the package includes basic stochastic simulation algorithms. The package includes several example networks which can be easily modified for other networks. Serial and parallel MPI implementations can be built and called from the command line. The serial implementation of the package can also be called from Matlab via the MEX interface with limited functionality. It supports many user specified options, including the use of antithetic sampling that can be used in some cases to increase efficiency.

SeSAm (Shell for Simulated Agent Systems) provides a generic environment for modelling and experimenting with agent-based simulation with a special focus on the easy construction of complex models including dynamic interdependencies or emergent behaviour

A Simple and Efficient Framework for Infinite Resolution Simulation; provides a Java Thread-like class that executes over simulated time. Time units are user-definable, no time quanta, and neither changes to the VM nor pre-processing are required.

Pseudo-Random Number Generation library for GPGPU

This android app is producing music and partition sheets in real time. Furthermore, the AI module can be activated and be trained to learn you prefered style and play it. You can also team play your music with the interconnect mode. Finally, move your phone like a 'chef d'orchestre' and see how it changes the music...

Interface between SystemBuil and High Level Architecture.

The TErminology for the Description of DYnamics (TEDDY) project aims to provide an ontology for dynamical behaviours, observable dynamical phenomena, and control elements of bio-models and biological systems in Systems Biology and Synthetic Biology.

That project aims at studying the impact of IT systems interactions on traveller demand and airline revenues. Passenger demand is generated (Monte Carlo) and injected into simulated CRS and airline IT systems. Differential analysis is then performed on various changes compared to a bottom line scenario.

This project is a public domain application that is written in Matlab that models the ISA100.11a protocol stack for industrial wireless devices.

This project aims to model parasites in order to assist in the analysis and prediction of their behavior.

Xcarecrows4MDA provides a complete toolset to build models and check their behavior for standalone applications or whole systems with a hierarchical, state driven approach. A test component checks the safety of the model under various situations.

The Xholon project explores: software as systems of linked nodes, organized hierarchically. The Xholon toolkit supports this back-to-basics approach, and demonstrates practical benefits through examples from numerous domains.

The aXBench (AUTOSAR extensible workbench) is a free eclipse plugin for modeling variant system architectures. This project collects modeling examples for the aXBench without having ti deal with the source code of the aXBench.

Cppfunct implements run-time C++ function objects, with creation, invocation, manipulation, and combination. The function object concept abstracts ways to parameterise other classes beyond simple static values.

DEVSimPy is an advanced wxPython GUI for the modeling and simulation of systems based on the DEVS (Discrete EVent system Specification) formalism. Features include powerful built-in editor, advanced modeling approach, powerful discrete event simulation algorithm, import/export DEVS components library and more.

This software allow you to design a Zagi rc plane.

java-turing-emulator aims to provide a GUI for creating, editing and simulating Turing machines and deterministic machines. its build in java and uses the swt-framework.

jsshagent is an open source project in Java language. It is a Robocup 3D Soccer Humanoid Simulation team.
