Open Source Java UML Tools for BSD

The bflow* Toolbox is an open source tool kit for business process management. The objective of bflow* is to explore new ways and scenarios for the development and use of modelling tools.

Mimosa is a modeling and simulation platform, covering the process from building conceptual models to running the simulations. The specification uses ontologies and an extensible set of formalisms for the dynamics. The simulation kernel is based on DEVS.

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.

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

Calculation of camshafts - allows to define a camshaft profile on the set trajectory which should provide the given mechanism. The trajectory can be set graphically, co-ordinates or function.

Japrosim is a java library for both discrete event and continuous simulation. GUI for modeling and automatic code generation are offered. An explanation module is integrated. Models are described in XML and owl for interoperability.

Java Fuzzy Editor is a basic editor to allow creation of fuzzy based rules. It will save to serveral formats including to source code in several languages.

Metaquokka is a highly configurable xml editor, currently available as Gridsphere portlet. Besides the default format, there is suppoert for ESysXML, a simulation description scheme for a geodynamics framework. Supports Generic Mapping Tools rudimentary.

SYSTEM FOR DESIGNING AND SIMULATE CONCURRENT AND DISTRIBUTED PROGRAMS IN CLUSTER ARCHITECTURE Provides graphical interface for configuring relationships between cooperating, abstract processes and simulate it in real cluster environment, using MPI.

Narrator is a graphical modelling tool for the description of dynamical systems and processes. Narrator is SBML compatible.

The Network Security Response Framework (NSRF) allows for testing different computer security response engines and methodologies. It supports simulated and real: Intrusion Detection Systems (sensors), Attacks, and Responses.

PeerSE is a graphical experiment environment for analysing and developing peer-to-peer (p2p) systems in Java.

PerMoTo is a Performance Modelling Tool suite for decision support in the capacity and performance management of distributed transaction processing systems based on Queueing Theory and Discrete Event Simulation.

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 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.

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.

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.

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.
