Open Source Simulation Software

Software for sustainability assessment, highly modular; initially focused on Life Cycle Assessments.

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.

The BioEnergy Allocation and Simulation Tool (BEAST) is a tool dedicated to assess political goals of woody bioenergy production in the context of available biomass potentials and corresponding economic and ecological criteria on a regional level. It is a useful tool in participative decision making processes by iterative simulation and visualization of complex issues. BEAST is a data- and model-driven Decision Support System (DSS) evaluating woody biomass potentials from forests, hedges and trees outside forests as well as short rotation coppice (SRC). The latter one is modelled spatially explicit. This opens the possibility to identify prefered areas for SRC production under different restrictions and goals. Forest wood and wood from outside forests are treated only aggregated.

CRAFTY is a large-scale ABM of land use change. It has been designed to allow efficient but powerful simulation of a wide range of land uses and the goods and services they produce. It is fully open-source and can be used without the need for any programming.

This software enable cannabis grower to manage and retrieve statistics about culture, tools included have the goal to help growing indoor cannabis.

EcoMod is an OpenGL application for 3D modelling, simulation and visualization of ecosystems. Trees are modelled and used within simulation to render the emerging natural phenomena of spontaneous afforestation process. Multidisciplinary.

Extended Bioaccumulation Framework (ExBAF) is a tool for assessing bioaccumulation in foodwebs. Supports several bioaccumulation models and provides tools for analysis and visualization.

GridSweeper makes it easy to perform batch runs of scientific simulation programs on computational grids/distributed resource management systems.

JaWator is a Wa-Tor JavaApplet; a predator-prey simulation resembling a natural ecosystem, this Cellular Automaton delivers fluctuations similar to the Lotka-Volterra equation. Inspired by A.K. Dewdney, Wa-Tor ecosystem (Scientific American, 1984)

MED-FOES is an implementation of a stochastic Agent-Based Simulation (ABS) system for analyzing demographic changes in a single population of Medfly (Ceratitis capitata) over time. The simulation currently takes population extinction as a given because it aims to give us better estimates of necessary quarantine lengths in areas where Medfly is not currently established but does repeatedly invade. Thus the objective of this software is to estimate the time to local extirpation based on known ranges of developmental, survivorship and reproductive parameters, as well as assumed ranges of an eradication pressure parameter. For a complete analysis and estimate of time to extirpation one would execute a large number of individual simulations evenly distributed over parameter space to estimate the time at which an arbitrary percentage of the simulations show extirpation.

PredatorPreySimulation is a graphical Java application for simulating a predator prey ecosystem using the Volterra-Lotka equations.

A collection of modules and enduser tools designed to help design, test and use system models. While my research (hence, the examples) is focused on hydro-ecological systems, the program can be used on any system characterized by ODEs (and soon PDEs?)

That project aims at providing a clean API, and the corresponding C++ implementation, able to generate demand for travel solutions (e.g., from JFK to PEK on 25-05-2009) according to characteristics (e.g., Willingness-To-Pay, preferred airline, etc).

UIBM (= Universal Individual-Based Model) is an agent-based simulation/3d-dvisualization of the dynamics within multispecies plant communities of Northwest Europe, parameterized from databases using universal scaling laws.

mesoFON is an individual-based mangrove forest model. It is a Java implementation of the KiWi model done with RePast Simphony. It contains several new features: (1) You can add up to 10 species via the GUI. However, in principle, the number of species to be included programmatically is unlimited. (2) You can use a variety of growth functions via typing them in as a string on the GUI. (3) The model is transparent, sinc it comes with the Eclipse workbench of RePast.
