System dynamics and discrete event modeling with some agent-based capabilities. It is 100% browser based with an open support group using Google mail list.
Insight Maker supports System Dynamics modeling: a powerful method for exploring systems on an aggregate level. These differences are due to the fact that GoldSim is primarily used for engineering and scientific applications where quantitative probabilistic predictions of future performance are required.įree, Insight Maker Public License (GPL adjusted)
DYNAMO software for microcomputers may be available via eBay or other resale sites.ĭiffers from traditional system dynamics approaches in that 1) it puts much greater emphasis on probabilistic simulation techniques to support representation of uncertain and/or stochastic systems and 2) it provides a wide variety of specialized model objects (beyond stocks, flows and converters) in order to make models less abstract (and hence more transparent) and help represent processes and events that cannot easily be represented using a traditional system dynamics approach. Historic DYNAMO models are often available at the MIT system dynamics website. Proprietary, no longer distributed commercially Suitable for large-scale systems, boundary value problems, Monte Carlo models, curve fitting, root finding, batch processes, parameter plots, stiff systems, etc. Solves ordinary differential equations (initial conditions and boundary value problems), difference equations (initial conditions and boundary value problems), multi-dimensional transcendental algebraic equation roots, discrete simulations using conveyors, ovens, and queues. Supports system dynamics, agent based and discrete event modeling, allows making hybrid models.įor solving small to very large mathematical models, systems of non-linear equations, linear and nonlinear optimisation problems, dynamic systems expressed as differential-algebraic equations.ĭeveloped on Berkeley campus under sponsorship of NSF and NIH, used by academic and commercial institutions to build mathematical models for research and teaching. Proprietary, commercial, free Personal Learning Edition (PLE) for education, formal or not Uses influence diagrams to define, navigate, and document models. Supports system dynamics, Monte Carlo simulation for uncertainty, array abstraction for handling multidimensional data, linear and non-linear optimization.
