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.
