Multimodels and Dynamic Structure Models: An Integration of DSDE/DEVS and OOPM

Constructing models of systems that change their structure over time has proved to be a challenging problem, with several proposed solutions. We present two of these approaches and discuss their integration. The Parallel Dynamic Structure Discrete Event System Specification is based on systems theoretic concepts and provides a formal specification of variable structure models. Object Oriented Physical Modeling (OOPM) extends the designs approaches of software engineering and employs both static and dynamic models to describe physical objects. OOPM is based on the multimodel concept to support adaptive structures. The integration is achieved by representing multimodels within the dynamic structure DEVS formalism. Since the latter has been implemented in HLA-compliant form, the integration has the practical consequence that multimodels can be directly mapped into distributed simulations.
