Elementary transition systems

Abstract: Transition systems are a simple and powerful formalism for explaining the operational behaviour of models of concurrency. They provide a common framework for investigating the interrelationships between different approaches to the study of distributed systems. Hence an important question to be answered is: which subclass of transition systems corresponds to a particular model of distributed systems? In this paper we provide an answer to this question for elementary net systems.

Unifying Petri Nets

Abstract: The increasing number of Petri net variants naturally leads to the question whether the term “Petri net” is more than a common name for very different concepts. This contribution tries to identify aspects common to all or at least to most Petri nets. It concentrates on those features where Petri nets significantly differ from other modeling languages, i.e. we ask where the use of Petri nets leads to advantages compared to other languages. Different techniques that are usually comprised under the header “analysis” are distinguished with respect to the analysis aim. Finally, the role of Petri nets in the development of distributed systems is discussed.

Concurrency and Nets

Abstract: Many approaches are being developed for handling the different phases in the design of complex information systems, namely specification, verification, evaluation, implementation and testing. These approaches are more or less applicable to the various specific aspects of the design phases and partially supported by efficient tools. This paper deals with one of the most important approaches used in the design of information systems, i. e., the Petri net based models approach, which proves particularly interesting. It is indicated how Petri net based models are used to represent systems behavior and then some of the resulting advantages are given. Furthermore, it is emphasized why and how a Petri net based approach can support all the design phases and it is made clear for which purposes and in which applications Petri net based designs are important. are also given. A few illustrative examples

Petri nets: Properties, analysis and applications

Abstract: Starts with a brief review of the history and the application areas considered in the literature. The author then proceeds with introductory modeling examples, behavioral and structural properties, three methods of analysis, subclasses of Petri nets and their analysis. In particular, one section is devoted to marked graphs, the concurrent system model most amenable to analysis. Introductory discussions on stochastic nets with their application to performance modeling, and on high-level nets with their application to logic programming, are provided. Also included are recent results on reachability criteria. Suggestions are provided for further reading on many subject areas of Petri nets. >
