Available in PDF, EPUB and Kindle. Book excerpt: This book gives a Petri net based solution to the challenge of simulation, analysis and verification of parallel programs. The presented formal definition of compositional high-level Petri net semantics for B(PN)2 (Basic Petri Net Programming Notation) programs and SDL (Specification Description Language) systems allows the correct and efficient translation of also recursive procedures (in B(PN)2 and SDL) and processes with dynamic creation and termination (in SDL) into high-level Petri nets. All related issues are covered: 1. The algebra of M-nets is extended 2. References relating parts of the programs with parts of the resulting nets are introduced 3. Its implementation in the PEP tool is described 4. Examples (including verification) are given 5. An extension to hybrid systems is shown

Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this paper is to determine the feasibility and produceability of a Petri net based CASE tool, thus the majority of this paper is the implementation and explanation thereof. The requirements of this implementation are as follows: a. Graphical input and manipulation of a Petri net. b. The generation of a formal definition from a given graph. c. The generation of code from a given formal definition. d. A CASE library to support parallel structures. During the implementation of this thesis it became apparent that a static dictionary for the CASE library would not be sufficient and a means to allow for customizing was required. Providing this programmability was not the topic of this thesis, but has become a substantial facet and possibly is a topic in and of itself. I leave it to the reader/user to explore the extents of that realm. The Apple Macintosh, due to its graphic ability and availability was selected as the platform for this implementation. This version of the program requires a color Macintosh and does not support many of the Macintoshs standard features. The implementation presented in this document meets the above requirements, and has produced executable code. At present the program consists of two separate applications that take the user from Petri net to executing code. The first handles all graphical input and editing of the Petri net and culminates in the generation of the formal definition. The second program generates the code from the formal definition and the library language. The separation is required for the later to be easily transferrable to any computing platform while the graphical interface is machine specific. Due to the requirements of the supporting NASA project, the code generated is Occam, and the target processor is the Inmos Transputer"--Document.

Download or read book Concurrent Object Oriented Programming and Petri Nets written by Gul A. Agha and published by Springer. This book was released on 2003-06-29 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concurrency and distribution have become the dominant paradigm and concern in computer science. Despite the fact that much of the early research in object-oriented programming focused on sequential systems, objects are a natural unit of distribution and concurrency - as elucidated early on by research on the Actor model. Thus, models and theories of concurrency, the oldest one being Petri nets, and their relation to objects are an attractive topic of study. This book presents state-of-the-art results on Petri nets and concurrent object-oriented programming in a coherent and competent way. The 24 thoroughly reviewed and revised papers are organized in three sections. The first consists of long papers, each presenting a detailed approach to integrating Petri nets and object-orientation. Section II includes shorter papers with emphasis on concrete examples to demonstrate the approach. Finally, section III is devoted to papers which significantly build on the Actor model of computation.

Available in PDF, EPUB and Kindle. Book excerpt: In modern society services and support provided by computer-based systems have become ubiquitous and indeed have started to fund amentally alter the way people conduct their business. Moreover, it has become apparent that among the great variety of computer technologies available to potential users a crucial role will be played by concurrent systems. The reason is that many commonly occurring phenomena and computer applications are highly con current : typical examples include control systems, computer networks, digital hardware, business computing, and multimedia systems. Such systems are characterised by ever increasing complexity, which results when large num bers of concurrently active components interact. This has been recognised and addressed within the computing science community. In particular, sev eral form al models of concurrent systems have been proposed, studied, and applied in practice. This book brings together two of the most widely used formalisms for de scribing and analysing concurrent systems: Petri nets and process algebras. On the one hand , process algebras allow one to specify and reason about the design of complex concurrent computing systems by means of algebraic operators corresponding to common programming constructs. Petri nets, on the other hand, provide a graphical representation of such systems and an additional means of verifying their correctness efficiently, as well as a way of expressing properties related to causality and concurrency in system be haviour.

Download or read book Nets Terms and Formulas written by E. -R. Olderog and published by Cambridge University Press. This book was released on 2005-08-22 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author presents a theory whereby nets, terms and formulas represent concurrent process at three levels of abstractions: Petri nets are used to describe all details of the operational machine behavior of processes. Algebraic process terms such as Calculus of Communicating Systems (CCS) or Communicating Sequential Processes (CSP) two of the main models for parallel programming, are used to describe the architecture of processes, i.e. how they can be composed from subprocesses. Logical formulas of a first-order trace logic are used to describe the safety and liveness aspects of the communication behavior of processes as required by their users. The main emphasis and technical contribution of this theory are transformations for a top-down design of concurrent processes starting with formulas and proceeding through terms to nets.

This book was released on 1989-08-09 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work relates different approaches for the modelling of parallel processes. On the one hand there are the so-called "process algebras" or "abstract programming languages" with Milner's Calculus of Communicating Systems (CCS) and the theoretical version of Hoare's Communicating Sequential Processes (CSP) as main representatives. On the other hand there are machine models, i.e. the classical finite state automata (transition systems), for which, however, more discriminating notions of equivalence than equality of languages are used; and secondly, there are differently powerful types of Petri nets, namely safe and general (place/transition) nets respectively, and predicate/transition nets. Within a uniform framework the syntax and the operational semantics of CCS and TCSP are explained. We consider both, Milner's well-known interleaving semantics, which is based on infinite transition systems, as well as the new distributed semantics introduced by Degano et al., which is based on infinite safe nets. The main part of this work contains three syntax-driven constructions of transition systems, safe nets, and predicate/transition nets respectively. Each of them is accompanied by a proof of consistency. Due to intrinsic limits, which are also investigated here, neither for transition systems and finite nets, nor for general nets does a finite consistent representation of all CCS and TCSP programs exist. However sublanguages which allow finite representations are discerned. On the other hand the construction of predicate/transition nets is possible for all CCS programs in which every choice and every recursive body starts sequentially.

Download or read book Hardware Design and Petri Nets written by Alex Yakovlev and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardware Design and Petri Nets presents a summary of the state of the art in the applications of Petri nets to designing digital systems and circuits. The area of hardware design has traditionally been a fertile field for research in concurrency and Petri nets. Many new ideas about modelling and analysis of concurrent systems, and Petri nets in particular, originated in theory of asynchronous digital circuits. Similarly, the theory and practice of digital circuit design have always recognized Petri nets as a powerful and easy-to-understand modelling tool. The ever-growing demand in the electronic industry for design automation to build various types of computer-based systems creates many opportunities for Petri nets to establish their role of a formal backbone in future tools for constructing systems that are increasingly becoming distributed, concurrent and asynchronous. Petri nets have already proved very effective in supporting algorithms for solving key problems in synthesis of hardware control circuits. However, since the front end to any realistic design flow in the future is likely to rely on more pragmatic Hardware Description Languages (HDLs), such as VHDL and Verilog, it is crucial that Petri nets are well interfaced to such languages. Hardware Design and Petri Nets is divided into five parts, which cover aspects of behavioral modelling, analysis and verification, synthesis from Petri nets and STGs, design environments based on high-level Petri nets and HDLs, and finally performance analysis using Petri nets. Hardware Design and Petri Nets serves as an excellent reference source and may be used as a text for advanced courses on the subject.

Download or read book Understanding Petri Nets written by Wolfgang Reisig and published by Springer Science & Business Media. This book was released on 2013-07-03 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: With their intuitive graphical approach and expressive analysis techniques, Petri nets are suitable for a wide range of applications and teaching scenarios, and they have gained wide acceptance as a modeling technique in areas such as software design and control engineering. The core theoretical principles have been studied for many decades and there is now a comprehensive research literature that complements the extensive implementation experience. In this book the author presents a clear, thorough introduction to the essentials of Petri nets. He explains the core modeling techniques and analysis methods and he illustrates their usefulness with examples and case studies. Part I describes how to use Petri nets for modeling; all concepts are explained with the help of examples, starting with a generic, powerful model which is also intuitive and realistic. Part II covers the essential analysis methods that are specific to Petri nets, introducing techniques used to formulate key properties of system nets and algorithms for proving their validity. Part III presents case studies, each introducing new concepts, properties and analysis techniques required for very different modeling tasks. The author offers different paths among the chapters and sections: the elementary strand for readers who wish to study only elementary nets; the modeling strand for those who wish to study the modeling but not the analysis of systems; and finally the elementary models of the modeling strand for those interested in technically simple, but challenging examples and case studies. The author achieves an excellent balance between consistency, comprehensibility and correctness in a book of distinctive design. Among its characteristics, formal arguments are reduced to a minimum in the main text with many of the theoretical formalisms moved to an appendix, the explanations are supported throughout with fully integrated graphical illustrations, and each chapter ends with exercises and recommendations for further reading. The book is suitable for students of computer science and related subjects such as engineering, and for a broad range of researchers and practitioners.
