Extend: an interactive simulation tool

The Extend simulation environment provides the tools for all levels of modelers to efficiently create accurate, credible, and usable models. Extend´s design facilitates every phase of the simulation project, from creating, validating, and verifying the model, to the construction of a user interface which allows others to analyze the system. Simulation tool developers can use Extend´s built-in, compiled language, ModL, to create reusable modeling components. All of this is done within a single, self-contained software program that does not require external interfaces, compilers, or code generators.
