Hierarchical Control Flow Graph Models

Hierarchical Control Flow Graph Models deene a modeling paradigm for discrete event simulation modeling based upon hierarchical extensions to Control Flow Graph Models. Conceptually, models consist of a set of encapsulated, concurrently operating model components that interact solely via message passing. The primary objectives of Hierarchical Control Flow Graph Models are: (1) to facilitate model development by making it easier to develop, maintain, and reuse models and model elements, and (2) to support the exible and eecient execution of models. Hierarchical Control Flow Graph Models use two complementary types of hierarchical model speciication structures, one to specify components and their interconnections, and the other to specify component behaviors.
