A Formal Definition of Dynamic Structure Hybrid Simulation Model
F. Barros. 2008 22nd Workshop on Principles of Advanced and Distributed Simulation, page 149. (June 2008)
Summary form only given. The heterogeneous flow system specification (HFSS) is a modular formalism able to describe hybrid hierarchical models with a time-varying structure. The HFSS support for structural changes ranges from the addition/deletion of components and connections to the representation of mobile components. While using a traditional representation of discrete event systems, HFSS introduces the concept of generalized sampling to achieve the description of continuous signals. Sampling is treated as a first order concept being explicitly supported. We present the semantics of the HFSS formalism by introducing the new concept of HFSS component. This concept makes a clear distinction between model and component that have been usually employed interchangeably in M&S. The herein developed concept of component introduces a novel abstraction in modeling and simulation and we expect it can contribute to extend the modeling and simulation ontology.
