We propose a hybrid architecture for the simulation of plants. Its core is a Petri Net executor based on a new class of Petri Nets called Extended Simple Colored Petri Nets. The executor is supervised by an expert system. Our architecture is very well-suited for the software-engineering development of plant simulators, as development times and errors can be dramatically reduced. The validity of...

This paper introduces a new direction in formalizing sociological models. Sociological theories are a field of application for computer science, hence sociologists describe a theory in informal ways. These theories are transformed into computational models which can be studied and investigated with formal methods. We have chosen to formalize a common model of sociological theory, the Garbage Ca...

Petri nets are a discrete event simulation approach developed for system representation, in particular for their concurrency and synchronization properties. Various extensions to the original theory of Petri nets have been used for modeling molecular biology systems and metabolic networks. These extensions are stochastic, colored, hybrid and functional. This paper carries out an initial review ...

Ensuring the correctness of concurrent programs is difficult, since common approaches for program design do not provide appropriate methods. This paper gives a brief introduction to Object Colored Petri Nets, which can be used for modeling the control flow of concurrent programs, for their simulation, and for deriving and proving specific properties. Emphasis will not rely upon the precise form...

This paper describes a generic model of matching that can be usefully applied to misuse intrusion detection. The model is based on Colored Petri Nets. Guards define the context in which signatures are matched. The notion of start and final states, and paths between them define the set of event sequences matched by the net. Partial order matching can also be specified in this model. The main ben...

Open distributed multi-agent systems are gaining interest in the academic community and in industry. In such open settings, agents are often coordinated using standardized agent conversation protocols. The representation of such protocols (for analysis, validation, monitoring, etc) is an important aspect of multi-agent applications. Recently, Petri nets have been shown to be an interesting appr...

Answering realistic questions about biological systems and pathways similar to the ones used by text books to test understanding of students about biological systems is one of our long term research goals. Often these questions require simulation based reasoning. To answer such questions, we need formalisms to build pathway models, add extensions, simulate, and reason with them. We chose Petri ...

In a robotic soccer team, goalkeeper is an important challenging role, which has different characteristics from the other teammates. This paper proposes a new learning-based behavior model for a soccer goalkeeper robot by using Petri nets. The model focuses on modeling and analyzing, both qualitatively and quantitatively, for the goalkeeper role so that we have a model-based knowledge of the ta...

In this work we introduce a new formal model for software components supporting behavioral interpretability based on temporal logic, Petri nets, model checking, and an assume–guarantee strategy to specify and reason about the composition of concurrent component systems. The formal specification and verification strategies, methods, and techniques presented in this work contribute to the develop...
