Vensim is used for developing, analyzing, and packaging
high quality dynamic feedback models. Models are constructed
graphically or in a text editor. Features include dynamic functions,
subscripting (arrays), Monte Carlo sensitivity analysis,
optimization, data handling, application interfaces, and much more.
Ventana Systems also provides the Molecules software, for
constructing system dynamics models from "chunks" or molecules of
system dynamics structure.
Vensim PLE (Personal Learning Edition) is software that gets you
started in system dynamics modeling and is free for educational use
and inexpensive for commercial use. Vensim PLE is ideal for
classroom use and personal learning of system dynamics.
Vensim PLE Plus
Vensim PLE Plus bridges the gap between the inexpensive (or free)
PLE and our higher configurations. PLE Plus is fully featured for
its price point and includes data connectivity, multiple views,
Monte Carlo sensitivity simulations, game simulations, and the new
model-user interface (Input and Output Controls).
Vensim Professional, and DSS
Read the Vensim Brochure. Vensim Professional is what is needed for
managing large and mode complicated models. It provides Causal
TracingTM of structure and behavior, and has Monte Carlo
sensitivity, optimization and subscripting (array) capabilities.
Vensim DSS adds an interface development tool for creating
management flight simulators, external functions and macros,
compiled simulations, and more.
The Vensim Model Reader is free software which allows you to publish
models constructed with Vensim and distribute them to other people.
Your model and the Vensim model reader can be copied and passed to
as many people as you want, giving people access to your model
without their needing to purchase Vensim.
The Molecules software is used for constructing system dynamics
models from "chunks" or molecules of system dynamics structure. This
software is a collaborative effort among a number of authors.
Custom Vensim applications (flight simulators and other interfaces
to models) can be developed with the Venapp builder, or in a
programming language such as Visual Basic, C, C++, Visual C++,
Delphi, Excel, and multimedia authoring tools, or in Sable (below).
