TL;DR: Today's modeling tools, appropriate for conventional sequential systems, will be inadequate for the complex concurrent systems of the 80's, and petri nets may offer a solution.

TL;DR: It is shown that efficient analysis techniques from PetriNet theory can be exploited for analysis of QPNs, thus supporting the general objective of combining Petri net and queueing network formalisms.
Abstract: System analysis is often needed with respect to both qualitative and quantitative aspects. In recent decades, several formalisms have been developed that attempt to combine these aspects in one description. Present emphasis is on stochastic Petri nets. One disadvantage of these formalisms is the difficulties when describing scheduling strategies with Petri net elements. A new version of queuing Petri nets (QPNs), which combines queuing networks and Petri nets, aiming at eliminating these disadvantages is described. The new version also exhibits the modeling of timed transitions and timeless queues for describing pure scheduling mechanisms. QPNs are a superset of queueing networks and (generalized stochastic) Petri nets. The analysis of QPNs is discussed, and it is shown that efficient analysis techniques from Petri net theory can be exploited for analysis of QPNs, thus supporting the general objective of combining Petri net and queueing network formalisms. >

TL;DR: The paper introduces the basic motivations for modelling DEDS and briefly overviews the basic results of net theory that are useful for the definition of Stochastic Petri Nets and Generalized Stochastics Nets and GSPNs.
Abstract: Stochastic Petri Nets are a modelling formalism that can be conveniently used for the analysis of complex models of Discrete Event Dynami Systems (DEDS) and for their performance and reliability evaluation. The automatic construction of the probabilistic models that underly the dynamic behaviours of these nets rely on a set of results that derive from the theory of untimed Petri nets. The paper introduces the basic motivations for modelling DEDS and briefly overviews the basic results of net theory that are useful for the definition of Stochastic Petri Nets and Generalized Stochastic Petri Nets. The different approaches that have been used for introducing the concept of time in these models are discussed in order to provide the basis for the definition of SPNs and GSPNs as well. Details on the solution techniques and on their computational aspects are provided. A brief overview of more advanced material is included at the end of the paper to highlight the state of the art in this field and to give pointers to relevant results published in the literature.

TL;DR: This talk presents the personal view of the current status of highlevel Petri nets, in particular Coloured Petri Nets, and the main challenges that need to be addressed.
Abstract: This talk presents my personal view of the current status of highlevel Petri Nets, in particular Coloured Petri Nets. What have we achieved over the last 25 years and what are the main challenges that need to be addressed in order to make high-level Petri nets more useful, e.g., to the software industry? What kind of language extensions and tool support do we need to make Petri net modelling, simulation and analysis accessible to the knowledgeable engineer? I will also briefly discuss the main areas which I believe are the most obvious candidates for further theoretical development.

TL;DR: The development of Coloured Petri Nets has been driven by the desire to develop a modelling language theoretically well-founded and versatile enough to be used in practice for systems of the size and complexity found in typical industrial projects.
Abstract: The development of Coloured Petri Nets (CP-nets or CPN) has been driven by the desire to develop a modelling language - at the same time theoretically well-founded and versatile enough to be used in practice for systems of the size and complexity found in typical industrial projects. To achieve this, we have combined the strength of Petri nets with the strength of programming languages. Petri nets provide the primitives for describing synchronisation of concurrent processes, while programming languages provide the primitives for definition of data types and manipulation of their data values.
