In February 2002, the Industrial and Systems Engineering (ISE) De partment at the University of Florida hosted a National Science Founda tion Workshop on Collaboration and Negotiation in Supply Chain Man agement and E Commerce. This workshop focused on characterizing the challenges facing leading edge firms in supply chain management and electronic commerce, and identifying research opportunities for de veloping new technological and decision support capabilities sought by industry. The audience included practitioners in the areas of supply chain management and E Commerce, as well as academic researchers working in these areas. The workshop provided a unique setting that has facilitated ongoing dialog between academic researchers and industry practitioners. This book codifies many of the important themes and issues around which the workshop discussions centered. The editors of this book, all faculty members in the ISE Department at the University of Florida, also served as the workshop's coordinators. In addition to workshop participants, we also invited contributions from leading academics and practitioners who were not able to attend. As a result, the chapters herein represent a collection of research contributions, monographs, and case studies from a variety of disciplines and viewpoints. On the aca demic side alone, chapter authors include faculty members in supply chain and operations management, marketing, industrial engineering, economics, computer science, civil and environmental engineering, and building construction departments.

The idea of this book came to us in October 2002 at the international conference “Production systems design, supply chain management and logistics” (Miedzyzdroje, Poland). This conference was organized by an initiative group from certain French and Polish Universities with the objective to find a new synergy and to develop a Pan European (West – East) cooperation in the areas of: Design of production systems Supply and inventory management Production planning and scheduling Facility location, transportation and logistics Supply chain optimisation via simulation The conference was focused on a wide spectrum of optimisation problems taking into account Supply Chain paradigms, which create a pivotal idea to increase the productivity of modern production systems. The editors proposed to the group members, to present their results for this book. Some well-known scientists agreed also to participate in this work and sent us their contribution. The main idea of this book is that now, it is necessary to consider all the stages of product life cycle in an integrated approach, from the product/process design to the customer delivering. For example at the product design stage, we need to analyse and to optimise all the supply chain. The book is composed of 20 chapters divided into three parts.

This book reports initial efforts in providing some useful extensions in - nancial modeling; further work is necessary to complete the research agenda. The demonstrated extensions in this book in the computation and modeling of optimal control in finance have shown the need and potential for further areas of study in financial modeling. Potentials are in both the mathematical structure and computational aspects of dynamic optimization. There are needs for more organized and coordinated computational approaches. These ext- sions will make dynamic financial optimization models relatively more stable for applications to academic and practical exercises in the areas of financial optimization, forecasting, planning and optimal social choice. This book will be useful to graduate students and academics in finance, mathematical economics, operations research and computer science. Prof- sional practitioners in the above areas will find the book interesting and inf- mative. The authors thank Professor B.D. Craven for providing extensive guidance and assistance in undertaking this research. This work owes significantly to him, which will be evident throughout the whole book. The differential eq- tion solver “nqq” used in this book was first developed by Professor Craven. Editorial assistance provided by Matthew Clarke, Margarita Kumnick and Tom Lun is also highly appreciated. Ping Chen also wants to thank her parents for their constant support and love during the past four years.

Continuous optimization is the study of problems in which we wish to opti mize (either maximize or minimize) a continuous function (usually of several variables) often subject to a collection of restrictions on these variables. It has its foundation in the development of calculus by Newton and Leibniz in the 17*^ century. Nowadys, continuous optimization problems are widespread in the mathematical modelling of real world systems for a very broad range of applications. Solution methods for large multivariable constrained continuous optimiza tion problems using computers began with the work of Dantzig in the late 1940s on the simplex method for linear programming problems. Recent re search in continuous optimization has produced a variety of theoretical devel opments, solution methods and new areas of applications. It is impossible to give a full account of the current trends and modern applications of contin uous optimization. It is our intention to present a number of topics in order to show the spectrum of current research activities and the development of numerical methods and applications.

Although transportation economists have advocated the tolling of urban streets as a mechanism for controlling congestion and managing travel demands for over 50 years, it is only recently that this idea has become practical. When compared to the alternative of building more roads, congestion pricing - in particular via electronic tolling - is attractive and has been adopted in countries around the world. Recent implementations in London, Singapore, and various cities in Norway, as well as a number of projects in the United States, have been judged successful. This book presents rigorous treatments of issues related to congestion pricing. The chapters describe recent advances in areas such as mathematical and computational models for predicting traffic congestion, determining when, where, and how much to levy tolls, and analyzing the impact of tolls on transporation systems. The analyses and methodologies developed in this book provide:- Mechanisms that aid in determining and comparing congestion pricing schemes- Methodologies for evaluating the efficiency of existing and proposed congestion pricing schemes- A means to predict the impact of pricing on urban transporation systems- Information essential to the financial and political success of congestion pricing programs.

It is intended that this book be used in senior- to graduate-level semester courses in optimization, as offered in mathematics, engineering, com puter science and operations research departments. Hopefully this book will also be useful to practising professionals in the workplace. The contents of the book represent the fundamental optimization mate rial collected and used by the author, over a period of more than twenty years, in teaching Practical Mathematical Optimization to undergradu ate as well as graduate engineering and science students at the University of Pretoria. The principal motivation for writing this work has not been the teaching of mathematics per se, but to equip students with the nec essary fundamental optimization theory and algorithms, so as to enable them to solve practical problems in their own particular principal fields of interest, be it physics, chemistry, engineering design or business eco nomics. The particular approach adopted here follows from the author's own personal experiences in doing research in solid-state physics and in mechanical engineering design, where he was constantly confronted by problems that can most easily and directly be solved via the judicious use of mathematical optimization techniques. This book is, however, not a collection of case studies restricted to the above-mentioned specialized research areas, but is intended to convey the basic optimization princi ples and algorithms to a general audience in such a way that, hopefully, the application to their own practical areas of interest will be relatively simple and straightforward.

A basic problem for the interconnection of communications media is to design interconnection networks for specific needs. For example, to minimize delay and to maximize reliability, networks are required that have minimum diameter and maximum connectivity under certain conditions. This work provides a recent solution to this problem. The subject of all five chapters is the interconnection problem. The first two chapters deal with Cayley digraphs which are candidates for networks of maximum connectivity with given degree and number of nodes. Chapter 3 addresses Bruijn digraphs, Kautz digraphs and their generalizations, which are candidates for networks of minimum diameter and maximum connectivity with given degree and number of nodes. Chapter 4 studies double loop networks, and Chapter 5 considers broadcasting and the gossiping problem.

This text offers a look at simplex-based as well as the more recent interior point techniques for solving linear programming problems. Starting with a review of the mathematical underpinnings of these approaches, the text provides details of the primal and dual simplex methods with the primal-dual, composite, and steepest edge simplex algorithms. This is then followed by a discussion of interior point techniques, including projective and affine potential reduction, primal and dual affine scaling, and path following algorithms. Also covered is the theory and solution of the linear complementarity problem using both the complementary pivot algorithm and interior point routines. A feature of the book is its early and extensive development, and use of duality theory. The book is aimed at students in the areas of mathematics, economics, engineering and management science, and professionals who need a sound foundation in the important and dynamic discipline of linear programming.

During the last three decades, breakthroughs in computer technology have made an impact on optimization. In particular, parallel computing has made it possible to solve larger and computationally more difficult problems. The book covers recent developments in novel programming and algorithmic aspects of parallel computing as well as technical advances in parallel optimization. Each contribution is essentially expository in nature, but of scholarly treatment. In addition, each chapter includes a collection of problems. The first two chapters discuss theoretical models for parallel algorithm design and their complexity. The next chapter gives the perspective of the programmer practicing parallel algorithm development on real world platforms. Solving systems of linear equations efficiently is of importance not only because they arise in many scientific and engineering applications but also because algorithms for solving many optimization problems need to call system solvers and subroutines (chapters four and five). Chapters six to 13 are dedicated to optimization problems and methods.They include parallel algorithms for network problems, parallel branch and bound techniques, parallel heuristics for discrete and continuous problems, decomposition methods, parallel algorithms for variational inequality problems, parallel algorithms for stochastic programming, and neural networks.

This text includes variants of the ellipsoid method for convex and quasiconvex problems and applies them to very general convex and quasiconvex models in location theory. It starts by describing the adopted notation and provides basic details of convexity and convex optimization. The second part of the book generalizes the new algorithm to solve quasiconvex programs. Although the techniques required by the quasiconvex case are more complex, the text provides a clear and direct interpretation of the main theoretical results.

The input data for data processing algorithms come from measurements and are therefore not precise. It is therefore necessary to estimate the accuracy of the results of data processing. Even for the simplest data processing algorithms, this problem is, however, intractable. This book describes for what classes of problems interval computations (i.e. data processing with automatic results verification) are feasible, and when they are intractable. This knowledge is important for algorithm developers, because it will enable them to concentrate on the classes of problems for which general algorithms are possible.

This work deals fundamentally with two of the most important aspects of personnel management, namely selection and job mobility. These topics are treated using late-1990s techniques created from all-purpose logic for handling uncertainty. Personnel recruitment is covered from the angle of selection techniques for improved efficiency for the company and greater satisfaction and self-realization for the employee. When considering workplaces, the suitability of each person and their mobility are studied under the best economic conditions. An alternative type of mathematics is used within this subject-matter is used for the development of models and algorithms. Complex subjects such as uncertainty are explained pedagogically starting from a low level and, when necessary, recourse has been made to reminders of basic aspects to enable a wide readership to profit from this work. This volume should be of interest to those whose work involves personnel management, production operation and manufacturing management, labour economics, industrial organization, operations research and management sciences.
