SYSTEM DYNAMICS MODEL BUILDER AND SIMULATOR

WIPO Patent Application WO2001001206

A9

A system dynamics modeling environment has a graphical user interface to allow a model developer to define a model through graphical inputs, for example by selecting icons and dragging them onto a representation of a flow diagram. The data and other information regarding a particular model are stored within a database structure that efficiently organizes the data. A second non-graphical editor is provided as a separate and distinct tool for editing the equations and other information representative of a model. The system dynamics modeling environment allows the definition of a plurality of groups, with each group consisting of a data set representing a complete flow diagram and capable of being coupled to another group defining a portion of the model on the same layer of the model. An efficient simulation environment is provided that determines which groups within a model are active and performs simulations only on those active groups. Users will also have the ability to create customized user interfaces, or "dashboards" for their models, without requiring programming experience. Users also have access to features that make it easy to create and save scenarios and models.
