We make the case that Discrete Event System Speciication (DEVS) is a universal formalism for discrete event dynamical systems (DEDS). DEVS ooers an expressive framework for modelling, design, analysis and simulation of autonomous and hybrid systems. We review some known features of DEVS and its extensions. We then focus on the use of DEVS to formulate and(More)
We report on a combination of system theoretic simulation modeling methodology with the JavaBeans component model as a basis for a component-based simulation framework. While system theory formalisms can serve as formal, mathematical foundations for modular, hierarchical modeling and simulation, the JavaBeans component model provides the appropriate(More)
This paper presents a new model for simulating Spiking Neural Networks using discrete event simulation which might possibly offer advantages concerning simulation speed and scalability. Spiking Neural Networks are considered as a new computation paradigm, representing an enhancement of Artificial Neural Networks by offering more flexibility and degree of(More)
End-users of automation software systems – which are the machine operators – have the task to provide machine settings and program simple control algorithms to adapt and optimize the machine to the specific automation tasks at hand. End-user programming systems are therefore an intrinsic part of automation systems. In this paper we report on a project with(More)
Product-line engineering and plug-in techniques pursue different but complementary goals. Software product line engineering strives for modeling the variability of software systems on different levels of abstraction, whereas plug-in systems support software extensibility, customizability, and evolution. We present an approach demonstrating the benefits of(More)
This paper presents a graphical modeling method and tool for DEVS model and DEVS-based combined discrete/continuous model specification. In DEVS-based modeling, atomic model behavior specification is organized around different phases which define a partition of the state space of the model. The phase transitions depict the qualitative state changes and(More)
Plug-in architectures and platforms represent a promising approach for building software systems which are extensible and customizable to the particular needs of the individual user. For example, the Eclipse platform, as the most prominent representative of plug-in systems, is based on a unique plug-in and extensibility concept and has succeeded in(More)
