Available in PDF, EPUB and Kindle. Book excerpt: More and more, our society and economy rely on the correct operation of, often hidden, critical infrastructures. These infrastructures such as the power grid and water and gas distribution networks, play an important role in our everyday life. Continuous supply of services from these assets is essential for people, organizations, and for the security and economy of our society. It is of substantial value to know or estimate how quickly such systems recover to acceptable levels of service after the occurrence of failures, natural disasters, e.g., fire, earthquakes, or cyber-attacks. Critical infrastructure and naturally hybrid, i.e., one needs both discrete and continuous quantities to realistically describe their behaviour. More-over, in many modern applications there is an intrinsic uncertainty. This is particularly true for dependability analysis of critical infrastructures, where one must model the occurrence of failure and repair in a system. In this dissertation we propose the use of an extended version of stochastic hybrid Petri nets. This modelling formalism combines discrete and continuous quantities with random discrete events. Furthermore, Petri nets provide a high level and easy-to-understand formalism. Particularly, we consider so called Hybrid Petri nets with General transitions (HPnG). The term general transition refers to the arbitrary nature of probability distribution that can be associated with stochastic variables in this model. HPnGs form a restricted subclass of stochastic hybrid models. The arbitrary nature of random discrete events in HPnGs is the main challenge for their analysis. We tackle the analysis of HPnGs by a conditioning argument on the occurrence times of random discrete events. This idea leads to an efficient generation of the underlying state space, which provides us with a structure such that measures of interest can be computed exacly and effectively. Unfortunately, the exact computation of measures of interests for complex syst

Available in PDF, EPUB and Kindle. Book excerpt: The world is full of events which cause, end or affect other events. The study of these events, from a system point of view, is very important. Such systems are called discrete event dynamic systems and are of a subject of immense interest in a variety of disciplines, which range from telecommunication systems and transport systems to manufacturing systems and beyond. There has always been an intense need to formulate methods for modelling and analysis of discrete event dynamic systems. Petri net is a method which is based on a well-founded mathematical theory and has a wide application. This book is a collection of recent advances in theoretical and practical applications of the Petri net method and can be useful for both academia and industry related practitioners.

This book was released on 2018-09-18 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Petri net formalism is useful in studying many discrete-state, discrete-event systems exhibiting concurrency, synchronization, and other complex behavior. As a bipartite graph, the net can conveniently capture salient aspects of the system. As a mathematical tool, the net can specify an analyzable state space. Indeed, one can reason about certain qualitative properties (from state occupancies) and how they arise (the sequence of events leading there). By introducing deterministic or random delays, the model is forced to sojourn in states some amount of time, giving rise to an underlying stochastic process, one that can be specified in a compact way and capable of providing quantitative, probabilistic measures. We formalize a new non-Markovian extension to the Petri net that captures both discrete and continuous timing in the same model. The approach affords efficient, stationary analysis in most cases and efficient transient analysis under certain restrictions. Moreover, this new formalism has the added benefit in modeling fidelity stemming from the simultaneous capture of discrete- and continuous-time events (as opposed to capturing only one and approximating the other). We show how the underlying stochastic process, which is non-Markovian, can be resolved into simpler Markovian problems that enjoy efficient solutions. Solution algorithms are provided that can be easily programmed.Jones, Robert L. and Goode, Plesent W. (Technical Monitor)Langley Research CenterPETRI NETS; MARKOV PROCESSES; SYNCHRONISM; ALGORITHMS

Download or read book Colored Petri Nets for Modeling of Discrete Systems written by Reggie Davidrajuh and published by Springer Nature. This book was released on 2023-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical approach to modeling real-world discrete systems and performing analysis. The theory behind the book is the Colored Petri nets, and the tool used for simulations is general-purpose Petri net simulator (GPenSIM). The theory part is kept to a minimum, and more explanation is given to the GPenSIM functions and how they can be used for modeling, simulation, and performance analysis. Real-world industrial systems possess a large number of resources. Modeling these systems with Petri nets would become a problem as they result in huge Petri net models. This book offers a unique solution to this problem by moving resources away from the Petri net model and treating them as variables in the background. Also, the theory and practice put forward in the book help cost estimation of the systems (e.g., manufacturing subsystems).

Download or read book Petri Nets for Modeling of Large Discrete Systems written by Reggie Davidrajuh and published by Springer Nature. This book was released on 2021-09-21 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a new Modular Petri Net as a solution to the vast Petri net models. It presents some approaches centering around modules (known as “Petri modules”). The goal of this book is to introduce a methodology in which Petri nets are moved to a new level. In this new level, large Petri net models are made of Petri modules, which are independent and run on different computers. This book also contains the literature study on modular Petri nets and definitions for the newer Petri modules. Also, algorithms for extracting Petri modules, and algorithms for connecting Petri modules, and applications are given in this book. Besides, the ideas and algorithms given in this book are implemented in the software General-purpose Petri Net Simulator (GPenSIM). Hence, with the use of this book the readers/users would be able to know that real-life discrete event systems could be modeled, analyzed, and performance-optimized with GPenSIM.

Available in PDF, EPUB and Kindle. Book excerpt: Driven by the request for increased productivity, flexibility, and competitiveness, modern civilization increasingly has created high-performance discrete event dynamic systems (DEDSs). These systems exhibit concurrent, sequential, competitive activities among their components. They are often complex and large in scale, and necessarily flexible and thus highly capital-intensive. Examples of systems are manufacturing systems, communication networks, traffic and logistic systems, and military command and control systems. Modeling and performance evaluation play a vital role in the design and operation of such high-performance DEDSs and thus have received widespread attention from researchers over the past two decades. One methodology resulting from this effort is based on timed Petri nets and related graphical and mathematical tools. The popularity that Petri nets have been gaining in modeling of DEDSs is due to their powerful representational ability of concurrency and synchronization; however these properties of DEDSs cannot be expressed easily in traditional formalisms developed for analysis of `classical' systems with sequential behaviors. This book introduces the theories and applications of timed Petri nets systematically. Moreover, it also presents many practical applications in addition to theoretical developments, together with the latest research results and industrial applications of timed Petri nets. Timed Petri Nets: Theory and Application is intended for use by researchers and practitioners in the area of Discrete Event Dynamic Systems.

Book excerpt: Any engineer who is responsible for the design and development of discrete systems, such as embedded software for control or telecommunication systems, knows that the most important quality of the final product is that it be functionally correct. Once assured that the system behaves correctly, it is also important that it be efficient in that its running cost is minimal or is optimum in whatever quanititive measure is chosen. Stochastic Petri nets have been developes over the last decade with exactly these objectives in mind.This book is an introduction to Stochastic Petri nets and arose out of a desire by the authors to collect all one needs to understand Stochastic Petri net theory in one volume. The intention of this book is not to give an overview of several or all Stochastic Petri net models appearing in the literature, but to stress a combined view of functional and performance analysis in the context of some Stochastic Petri net models.The book contains a reference to several Stochastic Petri net tools which are available to help the reader apply the theory contained in this volume.USP: Für sicher funktionierende DV-Systeme
