Book Synopsis Stochastic Simulation Optimization For Discrete Event Systems: Perturbation Analysis, Ordinal Optimization And Beyond by : Chun-hung Chen
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.

Book Synopsis Perturbations, Optimization, and Statistics by : Tamir Hazan
Download or read book Perturbations, Optimization, and Statistics written by Tamir Hazan and published by MIT Press. This book was released on 2017-09-22 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A description of perturbation-based methods developed in machine learning to augment novel optimization methods with strong statistical guarantees. In nearly all machine learning, decisions must be made given current knowledge. Surprisingly, making what is believed to be the best decision is not always the best strategy, even when learning in a supervised learning setting. An emerging body of work on learning under different rules applies perturbations to decision and learning procedures. These methods provide simple and highly efficient learning rules with improved theoretical guarantees. This book describes perturbation-based methods developed in machine learning to augment novel optimization methods with strong statistical guarantees, offering readers a state-of-the-art overview. Chapters address recent modeling ideas that have arisen within the perturbations framework, including Perturb & MAP, herding, and the use of neural networks to map generic noise to distribution over highly structured data. They describe new learning procedures for perturbation models, including an improved EM algorithm and a learning algorithm that aims to match moments of model samples to moments of data. They discuss understanding the relation of perturbation models to their traditional counterparts, with one chapter showing that the perturbations viewpoint can lead to new algorithms in the traditional setting. And they consider perturbation-based regularization in neural networks, offering a more complete understanding of dropout and studying perturbations in the context of deep neural networks.

Book Synopsis Multivalued Analysis and Nonlinear Programming Problems with Perturbations by : B. Luderer
Download or read book Multivalued Analysis and Nonlinear Programming Problems with Perturbations written by B. Luderer and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents a treatment of topological and differential properties of multivalued mappings and marginal functions. In addition, applications to sensitivity analysis of nonlinear programming problems under perturbations are studied. Properties of marginal functions associated with optimization problems are analyzed under quite general constraints defined by means of multivalued mappings. A unified approach to directional differentiability of functions and multifunctions forms the base of the volume. Nonlinear programming problems involving quasidifferentiable functions are considered as well. A significant part of the results are based on theories and concepts of two former Soviet Union researchers, Demyanov and Rubinov, and have never been published in English before. It contains all the necessary information from multivalued analysis and does not require special knowledge, but assumes basic knowledge of calculus at an undergraduate level.
Book Synopsis Perturbation Analysis, Optimization and Resource Contention Games in Stochastic Hybrid Systems by : Chen Yao
Download or read book Perturbation Analysis, Optimization and Resource Contention Games in Stochastic Hybrid Systems written by Chen Yao and published by . 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.

This book was released on 2018-07-10 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of real time guidance and optimal control of Aeroassisted Orbit Transfer Vehicles (AOTV's) was addressed using singular perturbation theory as an underlying method of analysis. Trajectories were optimized with the objective of minimum energy expenditure in the atmospheric phase of the maneuver. Two major problem areas were addressed: optimal reentry, and synergetic plane change with aeroglide. For the reentry problem, several reduced order models were analyzed with the objective of optimal changes in heading with minimum energy loss. It was demonstrated that a further model order reduction to a single state model is possible through the application of singular perturbation theory. The optimal solution for the reduced problem defines an optimal altitude profile dependent on the current energy level of the vehicle. A separate boundary layer analysis is used to account for altitude and flight path angle dynamics, and to obtain lift and bank angle control solutions. By considering alternative approximations to solve the boundary layer problem, three guidance laws were derived, each having an analytic feedback form. The guidance laws were evaluated using a Maneuvering Reentry Research Vehicle model and all three laws were found to be near optimal. For the problem of synergetic plane change with aeroglide, a difficult terminal boundary layer control problem arises which to date is found to be analytically intractable. Thus a predictive/corrective solution was developed to satisfy the terminal constraints on altitude and flight path angle. A composite guidance solution was obtained by combining the optimal reentry solution with the predictive/corrective guidance method. Numerical comparisons with the corresponding optimal trajectory solutions show that the resulting performance is very close to optimal. An attempt was made to obtain numerically optimized trajectories for the case where heating rate is constrained. A first order state variable inequality constra...

Book Synopsis Functional Analysis and Optimization Methods in Hadron Physics by : Irinel Caprini
Download or read book Functional Analysis and Optimization Methods in Hadron Physics written by Irinel Caprini and published by Springer. This book was released on 2019-04-25 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book begins with a brief historical review of the early applications of standard dispersion relations in particle physics. It then presents the modern perspective within the Standard Model, emphasizing the relation of analyticity together with alternative tools applied to strong interactions, such as perturbative and lattice quantum chromodynamics (QCD), as well as chiral perturbation theory. The core of the book argues that, in order to improve the prediction of specific hadronic observables, it is often necessary to resort to methods of complex analysis more sophisticated than the simple Cauchy integral. Accordingly, a separate mathematical chapter is devoted to solving several functional analysis optimization problems. Their applications to physical amplitudes and form factors are discussed in the following chapters, which also demonstrate how to merge the analytic approach with statistical analysis tools. Given its scope, the book offers a valuable guide for researchers working in precision hadronic physics, as well as graduate students who are new to the field.
Book Synopsis Semi-Infinite Programming by : Rembert Reemtsen
Download or read book Semi-Infinite Programming written by Rembert Reemtsen and published by Springer Science & Business Media. This book was released on 1998-04-30 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-infinite programming (briefly: SIP) is an exciting part of mathematical programming. SIP problems include finitely many variables and, in contrast to finite optimization problems, infinitely many inequality constraints. Prob lems of this type naturally arise in approximation theory, optimal control, and at numerous engineering applications where the model contains at least one inequality constraint for each value of a parameter and the parameter, repre senting time, space, frequency etc., varies in a given domain. The treatment of such problems requires particular theoretical and numerical techniques. The theory in SIP as well as the number of numerical SIP methods and appli cations have expanded very fast during the last years. Therefore, the main goal of this monograph is to provide a collection of tutorial and survey type articles which represent a substantial part of the contemporary body of knowledge in SIP. We are glad that leading researchers have contributed to this volume and that their articles are covering a wide range of important topics in this subject. It is our hope that both experienced students and scientists will be well advised to consult this volume. We got the idea for this volume when we were organizing the semi-infinite pro gramming workshop which was held in Cottbus, Germany, in September 1996.

Book Synopsis Analytic Perturbation Theory and Its Applications by : Konstantin E. Avrachenkov
Download or read book Analytic Perturbation Theory and Its Applications written by Konstantin E. Avrachenkov and published by SIAM. This book was released on 2013-12-11 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models are often used to describe complex phenomena such as climate change dynamics, stock market fluctuations, and the Internet. These models typically depend on estimated values of key parameters that determine system behavior. Hence it is important to know what happens when these values are changed. The study of single-parameter deviations provides a natural starting point for this analysis in many special settings in the sciences, engineering, and economics. The difference between the actual and nominal values of the perturbation parameter is small but unknown, and it is important to understand the asymptotic behavior of the system as the perturbation tends to zero. This is particularly true in applications with an apparent discontinuity in the limiting behavior?the so-called singularly perturbed problems. Analytic Perturbation Theory and Its Applications includes a comprehensive treatment of analytic perturbations of matrices, linear operators, and polynomial systems, particularly the singular perturbation of inverses and generalized inverses. It also offers original applications in Markov chains, Markov decision processes, optimization, and applications to Google PageRank? and the Hamiltonian cycle problem as well as input retrieval in linear control systems and a problem section in every chapter to aid in course preparation.
