Available in PDF, EPUB and Kindle. Book excerpt: Temporal resources are defined as human or capital resources with a per-unit-time capacity that can be allocated to different services or products in different periods of time. Examples of temporal resources include machinery, computing power, warehouses, venues, staff, and specialized technology such as a chemical reactor. In this dissertation, I study the problem of dynamically allocating temporal resources to maximize revenue or to minimize costs when the decision-maker is uncertain about the outcome of decisions. I consider two different problems that represent challenges encountered in various industries. In the first chapter, I provide an introduction to the two problems presented in Chapters 2 and 3, discuss the respective motivating industries, and provide examples of broader applications. The first problem, presented in Chapter 2, is the sales of cloud services to owners of interactive (user-based) applications such as websites and mobile apps. If an application owner purchases the service, the provider hosts the application on the cloud and provides the computing power required to support the application users. Here, the units of resource (hardware capacity) allocated to an application over time is directly determined by the traffic-pattern of the application's users. Considering the resource capacity, the provider dynamically prices services to maximize revenue. I model the provider's pricing problem as a large-scale stochastic dynamic program. I decompose this multi-dimensional stochastic dynamic program into single-dimensional sub-problems by proposing a tractable decomposition procedure. I then extend the proposed framework to define an individualized dynamic pricing mechanism for the cloud provider. To evaluate the performance of the proposed pricing mechanism, I present novel upper bounds on the optimal revenue. The computational results show that the proposed model of selling cloud services achieves significantly greater revenue than the prevalent alternative, and that the presented pricing scheme attains near-optimal revenue. In the third chapter of my dissertation I analyze a catalyst-activated batch-production process with uncertainty in production times, learning about catalyst-productivity characteristics, and decay of catalyst performance across batches. The challenge is to determine the quality level of batches and to decide when to replenish a catalyst so as to minimize average costs consisting of inventory holding, backlogging, and catalyst switching costs. The temporal resource in this problem is the common reactor shared across batches and multiple products. I formulate this problem as a Semi-Markov Decision Process (SMDP), and use structural properties of the SMDP to define an effective two-level heuristic which is easy to interpret and implement, and to establish a lower bound on the optimal average cost to evaluate the heuristic. Through application to data from a leading food processing company, I show that the proposed methodology, in addition to attaining near-optimal costs, outperforms current practice by an average of 22 % reduction in costs.

This book was released on 2006-06-12 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, leading researchers bring together current work on time perception and time-based prospective memory in order to understand how people time their intentions. This is the first account of many important topics concerning the timing of behavior, offered by scientists of diverse fields who in the past have exhibited an attitude of mutual 'benign neglect'. An explication of the rules which govern timing the future are of fundamental interest to anyone who wishes to explore the potential of human experience.Prospective memory — especially time-based — is a relatively unexplored way to study memory and few studies have been devoted to its neurobiological foundations. This volume aims to fill this void and will boost further interest in the field, while stimulating interdisciplinary research.

Download or read book Handbook of Optimization in Complex Networks written by My T. Thai and published by Springer Science & Business Media. This book was released on 2011-11-25 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex Social Networks is a newly emerging (hot) topic with applications in a variety of domains, such as communication networks, engineering networks, social networks, and biological networks. In the last decade, there has been an explosive growth of research on complex real-world networks, a theme that is becoming pervasive in many disciplines, ranging from mathematics and computer science to the social and biological sciences. Optimization of complex communication networks requires a deep understanding of the interplay between the dynamics of the physical network and the information dynamics within the network. Although there are a few books addressing social networks or complex networks, none of them has specially focused on the optimization perspective of studying these networks. This book provides the basic theory of complex networks with several new mathematical approaches and optimization techniques to design and analyze dynamic complex networks. A wide range of applications and optimization problems derived from research areas such as cellular and molecular chemistry, operations research, brain physiology, epidemiology, and ecology.
Download or read book Essays in Optimal Resource Allocation Under Uncertainty with Capacity Constraints written by Elizabeth Hoffman and published by . This book was released on 1979 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis brings together four papers on optimal resource allocation under uncertainty with capacity constraints. The first is an extension of the Arrow-Debreu contingent claim model to a good subject to supply uncertainty for which delivery capacity has to be chosen before the uncertainty is resolved. The second compares an ex-ante contingent claims market to a dynamic market in which capacity is chosen ex-ante and output and consumption decisions are made ex-post. The third extends the analysis to a storable good subject to random supply. Finally, the fourth examines optimal allocation of water under an appropriative rights system.

This book was released on 2006-03-30 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic and Robust Streaming in and between Connected Consumer-Electronic Devices addresses a subject that is becoming more important over the years. On the one hand the arrival of home networks is imminent, and on the other hand we notice that chips integrate more and more functionality. The home network interconnects the Consumer Electronic (CE) devices in the home, and the individual CE-devices incorporate the chips to realize a ubiquitous streaming of video streams over this network. This book provides a comprehensive overview of the challenges that face us. The book shows that there are many similarities between traditional networking and networks in the chip. However, there are some different operational conditions that lead to original solutions. Dynamic and Robust Streaming in and between Connected Consumer-Electronic Devices focuses on the robustness aspects of the chosen technologies in the area of video streaming. Management of resources such as memory, bandwidth, CPU cycles, bus–cycles is an aspect that is prominent in many of the sections.
Download or read book Evolutionary Multi objective Optimization in Uncertain Environments written by Chi-Keong Goh and published by Springer. This book was released on 2009-02-03 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary algorithms are sophisticated search methods that have been found to be very efficient and effective in solving complex real-world multi-objective problems where conventional optimization tools fail to work well. Despite the tremendous amount of work done in the development of these algorithms in the past decade, many researchers assume that the optimization problems are deterministic and uncertainties are rarely examined. The primary motivation of this book is to provide a comprehensive introduction on the design and application of evolutionary algorithms for multi-objective optimization in the presence of uncertainties. In this book, we hope to expose the readers to a range of optimization issues and concepts, and to encourage a greater degree of appreciation of evolutionary computation techniques and the exploration of new ideas that can better handle uncertainties. "Evolutionary Multi-Objective Optimization in Uncertain Environments: Issues and Algorithms" is intended for a wide readership and will be a valuable reference for engineers, researchers, senior undergraduates and graduate students who are interested in the areas of evolutionary multi-objective optimization and uncertainties.

Download or read book Approximate Dynamic Programming written by Warren B. Powell and published by John Wiley & Sons. This book was released on 2007-10-05 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete and accessible introduction to the real-world applications of approximate dynamic programming With the growing levels of sophistication in modern-day operations, it is vital for practitioners to understand how to approach, model, and solve complex industrial problems. Approximate Dynamic Programming is a result of the author's decades of experience working in large industrial settings to develop practical and high-quality solutions to problems that involve making decisions in the presence of uncertainty. This groundbreaking book uniquely integrates four distinct disciplines—Markov design processes, mathematical programming, simulation, and statistics—to demonstrate how to successfully model and solve a wide range of real-life problems using the techniques of approximate dynamic programming (ADP). The reader is introduced to the three curses of dimensionality that impact complex problems and is also shown how the post-decision state variable allows for the use of classical algorithmic strategies from operations research to treat complex stochastic optimization problems. Designed as an introduction and assuming no prior training in dynamic programming of any form, Approximate Dynamic Programming contains dozens of algorithms that are intended to serve as a starting point in the design of practical solutions for real problems. The book provides detailed coverage of implementation challenges including: modeling complex sequential decision processes under uncertainty, identifying robust policies, designing and estimating value function approximations, choosing effective stepsize rules, and resolving convergence issues. With a focus on modeling and algorithms in conjunction with the language of mainstream operations research, artificial intelligence, and control theory, Approximate Dynamic Programming: Models complex, high-dimensional problems in a natural and practical way, which draws on years of industrial projects Introduces and emphasizes the power of estimating a value function around the post-decision state, allowing solution algorithms to be broken down into three fundamental steps: classical simulation, classical optimization, and classical statistics Presents a thorough discussion of recursive estimation, including fundamental theory and a number of issues that arise in the development of practical algorithms Offers a variety of methods for approximating dynamic programs that have appeared in previous literature, but that have never been presented in the coherent format of a book Motivated by examples from modern-day operations research, Approximate Dynamic Programming is an accessible introduction to dynamic modeling and is also a valuable guide for the development of high-quality solutions to problems that exist in operations research and engineering. The clear and precise presentation of the material makes this an appropriate text for advanced undergraduate and beginning graduate courses, while also serving as a reference for researchers and practitioners. A companion Web site is available for readers, which includes additional exercises, solutions to exercises, and data sets to reinforce the book's main concepts.
Download or read book Time Action and Cognition written by Françoise Macar and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the outcome of the NATO Advanced Research Workshop on Time, Action and Cognition. which was held in Saint-Malo, France, in October 1991. The theme - time in action and cognition of time - was sparked by growing awareness in informal meetings between mostly French-speaking time psychologists of the need to bring together time specialists in the areas of development, motor behavior, attention, memory and representations. The workshop was designed to be a forum where different theoretical points of view and a variety of empirical approaches could be presented and discussed. Time psychologists tended to draw conclusions restricted to their specific fields of interest. From our own experience, we felt that addressing a common issue - possible relationships between time in action and representations of time - could lead to a more comprehensive approach. We are endebted to NATO for allowing us to bring this idea to fruition. We take this opportunity as well to express our thanks to Cognisciences ( Cognisud section) -- an active interdisciplinary research organization - for its financial backing and the CNRS for its scientific support.
