Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Network Flows Perhaps no subfield of mathematical programming is more alluring than network optimization. Highway, rail, electrical, communication and many other physical networks pervade our everyday lives. As a consequence, even non-specialists recognize the practical importance and the wide ranging applicability Of networks. Moreover, because the physical operating characteristics of networks flows on arcs and mass balance at nodes) have natural mathematical representations, practitioners and non-specialists can readily understand the mathematical descriptions of network Optimization problems and the basic nature Of techniques used to solve these problems. This combination of widespread applicability and ease of assimilation has undoubtedly been instrumental in the evolution of network planning models as one Of the most widely used modeling techniques in all of operations research and applied mathematics.

Download or read book Network Flows and Matching written by David S. Johnson and published by American Mathematical Soc.. This book was released on with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest has grown recently in the application of computational and statistical tools to problems in the analysis of algorithms. In many algorithmic domains, worst-case bounds are too pessimistic and tractable probabilistic models too unrealistic to provide meaningful predictions of practical algorithmic performance. Experimental approaches can provide knowledge where purely analytical methods fail and can provide insights to motivate and guide deeper analytical results. The DIMACS Implementation Challenge was organized to encourage experimental work in the area of network flows and matchings. Participants at sites in the U.S., Europe, and Japan undertook projects between November 1990 and August 1991 to test and evaluate algorithms for these problems. The Challenge culminated in a three-day workshop, held in October 1991 at DIMACS. This volume contains the revised and refereed versions of twenty-two of the papers presented at the workshop, along with supplemental material about the Challenge and the Workshop.
Download or read book Network flows and network design in theory and practice written by Jannik Matuschke and published by Jannik Matuschke. This book was released on 2014 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Network flow and network design problems arise in various application areas of combinatorial optimization, e.g., in transportation, production, or telecommunication. This thesis contributes new results to four different problem classes from this area, providing models and algorithms with immediate practical impact as well as theoretical insights into complexity and combinatorial structure of network optimization problems: (i) We introduce a new model for tactical transportation planning that employs a cyclic network expansion to integrate routing and inventory decisions into a unified capacitated network design formulation. We also devise several algorithmic approaches to solve the resulting optimization problem and demonstrate the applicability of our approach on a set of real-world logistic networks. (ii) We present approximation algorithms for combined location and network design problems, including the first constant factor approximation for capacitated location routing. (iii) We derive a max-flow/min-cut theorem for abstract flows over time, a generalization of the well-known work of Ford and Fulkerson that restricts to a minimal set of structural requirements. (iv) We devise algorithms for finding orientations of embedded graphs with degree constraints on vertices and faces, answering an open question by Frank.

Download or read book Flows in Networks Under Fuzzy Conditions written by Alexander Vitalievich Bozhenyuk and published by Springer. This book was released on 2016-07-30 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive introduction to fuzzy methods for solving flow tasks in both transportation and networks. It analyzes the problems of minimum cost and maximum flow finding with fuzzy nonzero lower flow bounds, and describes solutions to minimum cost flow finding in a network with fuzzy arc capacities and transmission costs. After a concise introduction to flow theory and tasks, the book analyzes two important problems. The first is related to determining the maximum volume for cargo transportation in the presence of uncertain network parameters, such as environmental changes, measurement errors and repair work on the roads. These parameters are represented here as fuzzy triangular, trapezoidal numbers and intervals. The second problem concerns static and dynamic flow finding in networks under fuzzy conditions, and an effective method that takes into account the network’s transit parameters is presented here. All in all, the book provides readers with a practical reference guide to state-of-the art fuzzy methods for solving flow tasks and offers a valuable resource for all researchers and postgraduate students in the fields of network theory, fuzzy models and decision-making.

This book was released on 2008-11-07 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors and authors dedicate this book to Bernhard Korte on the occasion of his seventieth birthday. We, the editors, are happy about the overwhelming feedback to our initiative to honor him with this book and with a workshop in Bonn on November 3–7,2008.Althoughthiswouldbeareasontolookback,wewouldratherliketolook forward and see what are the interesting research directions today. This book is written by leading experts in combinatorial optimization. All - pers were carefully reviewed, and eventually twenty-three of the invited papers were accepted for this book. The breadth of topics is typical for the eld: combinatorial optimization builds bridges between areas like combinatorics and graph theory, submodular functions and matroids, network ows and connectivity, approximation algorithms and mat- matical programming, computational geometry and polyhedral combinatorics. All these topics are related, and they are all addressed in this book. Combi- torial optimization is also known for its numerous applications. To limit the scope, however, this book is not primarily about applications, although some are mentioned at various places. Most papers in this volume are surveys that provide an excellent overview of an activeresearcharea,butthisbookalsocontainsmanynewresults.Highlightingmany of the currently most interesting research directions in combinatorial optimization, we hope that this book constitutes a good basis for future research in these areas.

Available in PDF, EPUB and Kindle. Book excerpt: "This book offers its readers a critical engagement with three key concepts for social and communication theory today - connectivity, networks and flows. The contributors are committed to conceptualizing contemporary communications in a changing world. They point to globalizing and deterritorializing processes, and to the increasing significance of mobilities in late modern existence - yet this is also a book about the continuing importance of locality, senses of place and physically copresent interaction in daily living." "Connectivity, Networks and Flows combines theoretical reflection with analysis of specific media and cultural practices. Featured examples of such practices include uses of mobile phones and the Internet, activities of online (and offline) working and socializing, and constructions of liveness and immediacy in electronically mediated communication. The book will be of particular interest to researchers and students in communications, media and cultural studies, sociology and social theory."--BOOK JACKET.
Download or read book Economic Geography written by Andrew Wood and published by Routledge. This book was released on 2012-10-12 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbulence of the current times has dramatically transformed the world’s economic geographies. The scale and scope of such changes require urgent attention. With intellectual roots dating to the nineteenth century, economic geography has traditionally sought to examine the spatial distributions of economic activity and the principles that account for them. More recently, the field has turned its attention to a range of questions relating to: globalization and its impact on different peoples and places; economic inequalities at different geographic scales; the development of the knowledge-based economy; and the relationship between economy and environment. Now, more than ever, the changing fortunes of peoples and places demands our attention. Economic Geography provides a stimulating and innovative introduction to economic geography by establishing the substantive concerns of economic geographers, the methods deployed to study them, the key concepts and theories that animate the field, and the major issues generating debate. This book is the first to address the diverse approaches to economic geography as well as the constantly shifting economic geographies on the ground. It encompasses traditional approaches, albeit from a critical perspective, while providing a thorough, accessible and engaging examination of the concerns, methods and approaches of the ‘new economic geography’. This unique introductory text covers the breadth of economic geography while engaging with a range of contemporary debates at the cutting-edge of the field. Written in an accessible and lucid style, this book offers a thorough and systematic introductory survey. It is enhanced by pedagogical features throughout including case studies dealing with topics ranging from the head office locations of the Fortune 500, Mexico’s maquiladoras to China’s investments in Southern Africa. This book also contains exercises based on the key concepts and annotated further reading and websites.
Download or read book Primal dual Interior Point Methods written by Stephen J. Wright and published by SIAM. This book was released on 1997-01-01 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, primal-dual algorithms have emerged as the most important and useful algorithms from the interior-point class. This book presents the major primal-dual algorithms for linear programming in straightforward terms. A thorough description of the theoretical properties of these methods is given, as are a discussion of practical and computational aspects and a summary of current software. This is an excellent, timely, and well-written work. The major primal-dual algorithms covered in this book are path-following algorithms (short- and long-step, predictor-corrector), potential-reduction algorithms, and infeasible-interior-point algorithms. A unified treatment of superlinear convergence, finite termination, and detection of infeasible problems is presented. Issues relevant to practical implementation are also discussed, including sparse linear algebra and a complete specification of Mehrotra's predictor-corrector algorithm. Also treated are extensions of primal-dual algorithms to more general problems such as monotone complementarity, semidefinite programming, and general convex programming problems.
