Generalized discrete event abstraction of continuous systems: GDEVS formalism
TLDR
A generalized discrete event model of an integrator using polynomial descriptions of input–output trajectories is presented, which has great capability of easily handling the delicate problem of input discontinuities and a detailed comparison with classical discrete time simulation methods is presented.About:

The Ecosystem in Practice: Interest and Problems of an Old Definition for Constructing Ecological Models
TL;DR: It is demonstrated that Tansley’s (Ecology 16:284–307, 1935) definition is still relevant to modern ecology almost as is, and a formal description of the concepts and relations linked to the ecosystem definition is proposed, as an ontology that can serve as a basis for future discussion, modelling and conceptual work.

Hybrid System Modeling: Using the Parallel DEVS Formalism and the Modelica Language
TL;DR: The objective of the presented work is to facilitate the description of discrete- event models and the discrete-event part of hybrid-DAE models by combining the Parallel DEVS formalism, the process-oriented modeling approach and the Modelica language.

Simulating Railway and Metropolitan Rail Networks: From Planning to On-line Control
TL;DR: The problem of evaluating skip-stop policies in a multi-line Metro system is studied using a novel event-driven simulator, and the requirements that a simulator must fulfill in order to be suitable for testing a particular system are stated.
Automated Simulation Model Generation
TL;DR: The research presented in this dissertation studied how to automatically generate simulation models and uses domain specific model components as building blocks for model generation and applies graph transformation based algorithms to compose large simulation models according to the existing data.

Theory of modeling and simulation
TL;DR: In this paper, the authors present a rigorous mathematical foundation for modeling and simulation and provide a comprehensive framework for integrating the various simulation approaches employed in practice, including cellular automata, chaotic systems, hierarchical block diagrams, and Petri nets.
DEVS representation of dynamical systems - Event-based intelligent control. [Discrete Event System Specification
TL;DR: It is shown how systems can be advantageously represented as discrete event models by using DEVS (discrete event system specification), set-theoretic formalism, which provides a basis for the design of event-based logic control.
