Studying the points on the disc where the trajectories pass through is often a lot simpler than studying the vector field as a whole. We go from dynamics in continuous time to dynamics in discrete time.

Eerst een oud idee van Henri Poincaré (1854-1912). Als men een vectorveld in de ruimte bestudeert kan het gebeuren dat er een schijf te vinden is waar de banen regelmatig voorbijkomen. Men kan dan de opeenvolging van de punten besruderen waar de banen de schijf ontmoeten, veeleer dan het geheel van de banen. Zulk een studie is dikwijls veel eenvoudiger : men gaat over van de dynamiek in continue tijd naar een dynamiek in discrete tijd.

The engineered systems of today are characterized by an ever increasing complexity. This complexity is often due, not only to a large number of compontents, but above all to heterogeneity of their components. To deal with this heterogeneity, and with the need to protect Intellectual Property (IP) of the authors of the components, co-simulation proposes to not expose the models inside components, but rather to orchestrate their simulation, using the minimal information necessary from the components to guarantee overall correct simulation. This thesis will work on the following problems: 1. To ensure correctness of the developed co-simulation protocols, automata models (for example, in UPPAAL) will be built of these protocols which are amenable to model checking. 2. The further development of the Functional Mockup Interface (FMI) co-simulation standard by investigating exactly what information needs to be exposed to allow for correct and efficient co-simulation. Both the mapping onto know formalisms (such as DEVS) and semantic adaptation will be investigated. The relationship with the High-Level Architecture (HLA) for distributed discrete-event simulation will be investigated. This, and the link with DEVS may lead to new features such as hierarchical co-simulation. 3. The briding of the continuous-discrete gap. This is an issue in so-called hybrid models, where continuous-time models such as differential equations are combined with discrete-time or discrete-event models. These typically result from the modelling of a physical system in its interaction with a software controller and possibly a network. In hybrid models, numerical approximations are made when discretizing continuous models to make them computable on digital devices. Furthermore, modelling constructs and techniques allowing state-event location are necessary. In this research, the primitives for modelling and co-simulation of hybrid models will be investitgated.

toenemende complexiteit. Deze complexiteit is vaak te wijten, niet enkel aan hun groot aantal componenten, maar bovenal aan de heterogeniteit van die componenten. Om deze complexiteit de baas te blijven, en om "intellectual property" (IP) van de auteurs van componenten te beschermen, stelt co-simulatie voor de modellen binnen de componenten te verbergen. Co-simulatie van de componenten wordt georchestreerd, met slechts minimale informatie uit de componenten die zichtbaar wordt gemaakt (doch voldoende om correcte simulatieresultaten te garadneren). De thesis werkt op de volgende problemen: 1. Model checking moet de correctheid van de te onwikkelen co-simulatie protocollen garanderen. 2. De verdere ontwikkeling van de Functional Mockup Interface (FMI) co-simulatie standaard vereist dat uitgemaakt wordt exact welke informatie in de interface van een Functional Mockup Unit (FMU) hoort om correcte en efficiente simulatie te garanderen. Zowel mappen op bestaande formalismen zoals DEVS als semantische adaptatie zullen onderzocht worden. De link met de High-Level Architecture (HLA) zal ook onderzocht worden. 3. Het overbruggen van de continu-discreet kloof in "hybride modellen".
