This book was released on 2011 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract:Stochastic Hybrid Systems (SHS) are systems that combine event-driven and time-driven dynamics, and include elements to model uncertainties in the system. There have been several different types of stochastic hybrid system models proposed. In this dissertation, a unified framework is presented for carrying out perturbation analysis for general SHS with arbitrary structures, in particular, the Infinitesimal Perturbation Analysis (IPA) methodology originally developed for Discrete Event Systems. Some properties are also established, which apply to this framework and justify its effectiveness in recovering useful performance sensitivity estimates. Then, this dissertation concentrates on Stochastic Flow Models (SFMs), which are one type of SHS and are used to abstract the dynamics of many complex discrete event systems to provide the basis for their control and optimization. SFMs have been used to date to study systems with a single user class or some multiclass settings in which performance metrics are not. class-dependent. However, little work has been done for multiclass systems that fully differentiate among classes, where classes contend for single or multiple system resources, and with class-dependent performance metrics. This is partly due to the complexities in modeling SFMs for such systems, and partly clue to the difficulties in applying IPA in this context. In this dissertation, a general framework is built based on multiclass SFMs, to model stochastic resource contention systems, where multiple classes (users) compete for shared resources. The general IPA framework is then applied to stick systems to obtain performance gradient estimates for various user-specific objectives, which enables the study of a new " user centric " optimization perspective, in addition to the usual "system-centric " viewpoint. Following the "user-centric " optimization, each class (user) seeks to optimize its own performance by adjusting its own controls, which leads to resource contention games between classes. A simple instance of such systems is studied to illustrate how the general IPA is applied to specific systems, and the difference between solutions of the two perspectives, which is commonly referred to as the "price of anarchy". Two specific resource contention problems are studied in this dissertation. One is the admission control problem for the multiclass queueing system under a First Come First Served (FCFS) policy, where the buffer capacity thresholds of all classes are determined to optimize system performance; the other problem is the multiclass lot-sizing problem arising in the manufacturing production planning setting, where the objective is to obtain optimal lot sizes for all classes. For both problems, the general IPA framework is applied to the multiclass SFM abstractions to derive sensitivity estimates of performance metrics with respect to control parameters of interest, which are all proven to be unbiased, hence, reliable for control and optimization purposes. These estimates arc then used to drive the on-line optimization of these parameters, and simulation results are provided to contrast the solutions obtained through the " system-centric " and "user-centric " perspectives.
Download or read book Stochastic Simulation Optimization For Discrete Event Systems Perturbation Analysis Ordinal Optimization And Beyond written by Chun-hung Chen and published by World Scientific. This book was released on 2013-07-03 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discrete event systems (DES) have become pervasive in our daily lives. Examples include (but are not restricted to) manufacturing and supply chains, transportation, healthcare, call centers, and financial engineering. However, due to their complexities that often involve millions or even billions of events with many variables and constraints, modeling these stochastic simulations has long been a “hard nut to crack”. The advance in available computer technology, especially of cluster and cloud computing, has paved the way for the realization of a number of stochastic simulation optimization for complex discrete event systems. This book will introduce two important techniques initially proposed and developed by Professor Y C Ho and his team; namely perturbation analysis and ordinal optimization for stochastic simulation optimization, and present the state-of-the-art technology, and their future research directions.

Available in PDF, EPUB and Kindle. Book excerpt: Illustrated with real-life manufacturing examples, Formal Methods in Manufacturing provides state-of-the-art solutions to common problems in manufacturing systems. Assuming some knowledge of discrete event systems theory, the book first delivers a detailed introduction to the most important formalisms used for the modeling, analysis, and control of manufacturing systems (including Petri nets, automata, and max-plus algebra), explaining the advantages of each formal method. It then employs the different formalisms to solve specific problems taken from today’s industrial world, such as modeling and simulation, supervisory control (including deadlock prevention) in a distributed and/or decentralized environment, performance evaluation (including scheduling and optimization), fault diagnosis and diagnosability analysis, and reconfiguration. Containing chapters written by leading experts in their respective fields, Formal Methods in Manufacturing helps researchers and application engineers handle fundamental principles and deal with typical quality goals in the design and operation of manufacturing systems.

Available in PDF, EPUB and Kindle. Book excerpt: Event-based systems are a class of reactive systems deployed in a wide spectrum of engineering disciplines including control, communication, signal processing, and electronic instrumentation. Activities in event-based systems are triggered in response to events usually representing a significant change of the state of controlled or monitored physical variables. Event-based systems adopt a model of calls for resources only if it is necessary, and therefore, they are characterized by efficient utilization of communication bandwidth, computation capability, and energy budget. Currently, the economical use of constrained technical resources is a critical issue in various application domains because many systems become increasingly networked, wireless, and spatially distributed. Event-Based Control and Signal Processing examines the event-based paradigm in control, communication, and signal processing, with a focus on implementation in networked sensor and control systems. Featuring 23 chapters contributed by more than 60 leading researchers from around the world, this book covers: Methods of analysis and design of event-based control and signal processing Event-driven control and optimization of hybrid systems Decentralized event-triggered control Periodic event-triggered control Model-based event-triggered control and event-triggered generalized predictive control Event-based intermittent control in man and machine Event-based PID controllers Event-based state estimation Self-triggered and team-triggered control Event-triggered and time-triggered real-time architectures for embedded systems Event-based continuous-time signal acquisition and DSP Statistical event-based signal processing in distributed detection and estimation Asynchronous spike event coding technique with address event representation Event-based processing of non-stationary signals Event-based digital (FIR and IIR) filters Event-based local bandwidth estimation and signal reconstruction Event-Based Control and Signal Processing is the first extensive study on both event-based control and event-based signal processing, presenting scientific contributions at the cutting edge of modern science and engineering.

This book was released on 2013-11-11 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial production is one of the most basic human activities indispensable to the economic activity. Due to its complexity, production is not very well understood and modeled as opposed to traditional fields of inquiry such as physics. This book aims at enhancing rigorous understanding of a particular area of production, that of analysis and optimization of production lines and networks using discrete event models and simulation. To our knowledge, this is the first book treating this subject from the point of view mentioned above. We have arrived at the realization that discrete event models and simulation provide perhaps the best tools to model production lines and networks for a number of reasons. Analysis is precise but demands enormous computational resources, usually unavailable in practical situations. Brute force simulation is also precise but slow when quick decisions are to be made. Approximate analytical models are fast but often unreliable as far as accuracy is concerned. The approach of the book, on the other hand, combines speed and accuracy to an exceptional degree in most practical applications.
