Download or read book Deadlock Resolution in Computer Integrated Systems written by MengChu Zhou and published by CRC Press. This book was released on 2018-10-08 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex computer-integrated systems offer enormous benefits across a wide array of applications, including automated production, transportation, concurrent software, and computer operating systems, computer networks, distributed database systems, and many other automated systems. Yet, as these systems become more complex, automated, distributed, and computing-intensive, the opportunity for deadlock issues rises exponentially. Deadlock modeling, detection, avoidance, and recovery are critical to improving system performance. Deadlock Resolution in Computer-Integrated Systems is the first text to summarize and comprehensively treat this issue in a systematic manner. Consisting of contributions from prominent researchers in the field, this book addresses deadlock-free models and scheduling, detection and recovery methods, the formulation of dynamic control policies, and comparison and industrial benchmark studies that evaluate various approaches. The editors lay the foundation for exploring deadlock issues with a typical example of an automated manufacturing process, illustrating three primary modeling methods (digraphs, Petri nets, and automata) and comparing their respective advantages and disadvantages. Providing all of the important models and resolution approaches, this book is the complete guide for electrical and control engineers and manufacturing, intelligent, and network systems designers to prevent and manage deadlock issues in their systems.

This book was released on 2009-03-04 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deadlock problems in flexible manufacturing systems (FMS) have received more and more attention in the last two decades. Petri nets are one of the more promising mathematical tools for tackling deadlocks in various resource allocation systems. In a system modeled with Petri nets, siphons are tied to the occurrence of deadlock states as a structural object. The book systematically introduces the novel theory of siphons, traps, and elementary siphons of Petri nets as well as the deadlock control strategies for FMS developed from it. Deadlock prevention methods are examined comparatively. The many FMS examples presented to demonstrate the concepts and results of this book range from the simple to the complex. Importantly, to inspire and motive the reader’s interest in further research, a number of interesting and open problems in this area are proposed at the end of each chapter.

Download or read book System Modeling and Control with Resource Oriented Petri Nets written by MengChu Zhou and published by CRC Press. This book was released on 2018-09-03 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petri nets are widely used in modeling, analysis, and control of discrete event systems arising from manufacturing, transportation, computer and communication networks, and web service systems. However, Petri net models for practical systems can be very large, making it difficult to apply such models to real-life problems. System Modeling and Control with Resource-Oriented Petri Nets introduces a new resource-oriented Petri net (ROPN) model that was developed by the authors. Not only does it successfully reduce model size, but it also offers improvements that facilitate effective modeling, analysis, and control of automated and reconfigurable manufacturing systems. Presenting the latest research in this novel approach, this cutting-edge volume provides proven theories and methodologies for implementing cost and time-saving improvements to contemporary manufacturing systems. It provides effective tools for deadlock avoidance—deadlock-free routing and deadlock-free scheduling. The authors supply simple and complex industrial manufacturing system examples to illustrate time-tested concepts, theories, and approaches for solving real-life application problems. Written in a clear and concise manner, the text covers applications to automated and reconfigurable manufacturing systems, automated guided vehicle (AGV) systems, semiconductor manufacturing systems, and flexible assembly systems. Explaining complex concepts in a manner that is easy to understand, the authors provide the understanding and tools needed for more effective modeling, analysis, performance evaluation, control, and scheduling of engineering processes that will lead to more flexible and efficient manufacturing systems.

Download or read book Control of Discrete Event Systems written by Carla Seatzu and published by Springer. This book was released on 2012-07-27 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of Discrete-event Systems provides a survey of the most important topics in the discrete-event systems theory with particular focus on finite-state automata, Petri nets and max-plus algebra. Coverage ranges from introductory material on the basic notions and definitions of discrete-event systems to more recent results. Special attention is given to results on supervisory control, state estimation and fault diagnosis of both centralized and distributed/decentralized systems developed in the framework of the Distributed Supervisory Control of Large Plants (DISC) project. Later parts of the text are devoted to the study of congested systems though fluidization, an over approximation allowing a much more efficient study of observation and control problems of timed Petri nets. Finally, the max-plus algebraic approach to the analysis and control of choice-free systems is also considered. Control of Discrete-event Systems provides an introduction to discrete-event systems for readers that are not familiar with this class of systems, but also provides an introduction to research problems and open issues of current interest to readers already familiar with them. Most of the material in this book has been presented during a Ph.D. school held in Cagliari, Italy, in June 2011.

Download or read book Real Time Management of Resource Allocation Systems written by Spyros A. Reveliotis and published by Springer Science & Business Media. This book was released on 2006-07-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-Time Management of Resource Allocation Systems focuses on the problem of managing the resource allocation taking place within the operational context of many contemporary technological applications, including flexibly automated production systems, automated railway and/or monorail transportation systems, electronic workflow management systems, and business transaction supporting systems. A distinct trait of all these applications is that they limit the role of the human element to remote high-level supervision, while placing the burden of the real-time monitoring and coordination of the ongoing activity upon a computerized control system. Hence, any applicable control paradigm must address not only the issues of throughput maximization, work-in-process inventory reduction, and delay and cost minimization, that have been the typical concerns for past studies on resource allocation, but it must also guarantee the operational correctness and the behavioral consistency of the underlying automated system. The resulting problem is rather novel for the developers of these systems, since, in the past, many of its facets were left to the jurisdiction of the present human intelligence. It is also complex, due to the high levels of choice – otherwise known as flexibility – inherent in the operation of these environments.

Book excerpt: The era of seemingly unlimited growth in processor performance is over: single chip architectures can no longer overcome the performance limitations imposed by the power they consume and the heat they generate. Today, Intel and other semiconductor firms are abandoning the single fast processor model in favor of multi-core microprocessors--chips that combine two or more processors in a single package. In the fourth edition of Computer Architecture, the authors focus on this historic shift, increasing their coverage of multiprocessors and exploring the most effective ways of achieving parallelism as the key to unlocking the power of multiple processor architectures. Additionally, the new edition has expanded and updated coverage of design topics beyond processor performance, including power, reliability, availability, and dependability.

Download or read book Implementation and Verification of Distributed Control Systems written by Christian Gerber and published by Logos Verlag Berlin GmbH. This book was released on 2011 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: There exist certain key issues to modern industrial automation as modularity, reusability, portability, flexibility, extendibility and reconfigurability to create optimally coordinated automation solution for manufacturing plants. This will feature the operating companies to react fast and flexible to changed customer demands. An appropriate way to realize these issues is an object-oriented control implementation, which has been quite common since the late 90s. This work is focused on the upcoming standard IEC 61499, which defines an object-oriented and event-driven software model, which can be realised by any hardware the engineer prefers. Furthermore, the control implementation is application-oriented and all parts are mapped to available control devices later on. Thus, it is possible to replace one device by another by easily remapping the application. But, does this possibility need certain care during the development of the control application and how could a control engineer be supported to prove the correctness of the plant behaviour in any case? To answer this question the formal model discrete timed Net Condition/Event Systems is used in this work to model in a modular manner the control system and the plant. Both models are connected in closed loop to perform a reachability analysis. It is shown, how a control engineer can examine in a graphical manner the system behaviour for all possible cases by selecting interesting trajectories and drawing them as Gantt-Charts. Since the model of the plant incorporates all sensors and actuators, the state of the corresponding places can be included into the Gantt-Chart.Even if the control engineer has no deep knowledge about the used formal model, this systematic and tool supported way ensures the possibility to analyse the system behaviour in any case, if he changes the control application or remaps it. This will reduce downtimes during production changes and new plant can be brought faster into service.

Download or read book A Performance Study of Deadlock Resolution in Distributed Systems written by Chidori Kawamura Boeheim and published by . This book was released on 1992 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed deadlock is a state where there exists among some processes running on different computers a cyclic wait to acquire some resources such that no process can proceed. Since a deadlock is a state that persists unless it is solved by some method, and the number and size of deadlocks increase substantially as the concurrency level or number of sites in a distributed system grows, we need an efficient approach to solve this problem. Distributed deadlock resolution consists of choosing a victim, aborting and restarting it. There has been no detailed study of resolution, despite the fact that deadlock detection does not complete its task without resolution. The performance analysis of different resolution strategies that have been proposed and new approaches for distributed deadlock resolution are the subject of this study. Different heuristic strategies (rules) to choose victims to break deadlocks are discussed and the direct and indirect goals that the rules were hypothesized to achieve are described. Various simulation runs (experiments) were conducted to analyze in depth the performance of the rules. The system throughput and the overhead of running the rules are evaluated and the effectiveness of each rule in achieving its goals are compared. The assessment of each rule under different system conditions is used to evaluate the possibility of incorporating more than one rule in deadlock resolution. This leads to the suggestion for use of a first-principles expert system to monitor and diagnose distributed systems, including the resolution of problems such as deadlocks. The rule base of such an expert system would include rules to choose the optimum victim to resolve a distributed deadlock.
