Object-based architecture, standardized specification, and DynaSim models. (A) Object-based architecture and standardized specification. Discrete model objects (populations and mechanisms) are shown in bold; any object can be stored independently in the library and reused as components of larger models. There is no limit on the number of objects in a DynaSim model. Fields of the standardized specification structure are underlined. Each population can have a list of intrinsic mechanisms; each directed pair of source and target populations can have a list of connection mechanisms. Optional objects are enclosed in parentheses. A string-based specification will be internally associated with a default population “pop1” in the standardized specification structure. (B) The standardized specification structure and model objects are parsed to generate a single set of equations describing the full model given the separate sets of equations for each object.
