A unified treatment of the vulnerabilities that exist in real-world network systems—with tools to identify synergies for mergers and acquisitions Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain World presents a comprehensive study of network systems and the roles these systems play in our everyday lives. This book successfully conceptualizes, defines, and constructs mathematically rigorous, computer-based tools for the assessment of network performance and efficiency, along with robustness and vulnerability analysis. The result is a thorough exploration that promotes an understanding of the critical infrastructure of today's network systems, from congested urban transportation networks and supply chain networks under disruption to financial networks and the Internet.The authors approach the analyses by abstracting not only topological structures of networks, but also the behavior of network users, the demand for resources, the resulting flows, and the associated costs. Following an introduction to the fundamental methodologies and tools required for network analysis and network vulnerability, the book is organized into three self-contained parts:Part I—Network Fundamentals, Efficiency Measurement, and Vulnerability Analysis explores the theoretical and practical foundations for a new network efficiency measure in order to assess the importance of network components in various network systems. Methodologies for distinct decision-making behaviors are outlined, along with the tools for qualitative analysis, the algorithms for the computation of solutions, and a thorough discussion of the unified network efficient measure and network robustness with the unified measure.Part II—Applications and Extensions examines the efficiency changes and the associated cost increments after network components are eliminated or partially damaged. A discussion of the recently established connections between transportation networks and different critical networks is provided, which demonstrates how the new network measures and robustness indices can be applied to different supply chain, financial, and dynamic networks, including the Internet and electronic power networks.Part III—Mergers and Acquisitions, Network Integration, and Synergies reveals the connections between transportation networks and different network systems and quantifies the synergies associated with the network systems, from total cost reduction to environmental impact assessment. In the case of mergers and acquisitions, the focus is on supply chain networks. The authors outline a system-optimization perspective for supply chain networks and also formalize coalition formation using game theory with insights into the merger paradox.With its numerous network examples and real-world applications, Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain World is an excellent book for courses in network science, transportation science, operations management, and financial networks at the upper-undergraduate and graduate levels. It is also a valuable reference for researchers and practitioners in the areas of applied mathematics, computer science, operations research, management science, finance, and economics, as well as industrial, systems, and civil engineering.Listen to Dr. Nagurney's podcast Supernetworks: Building Better Real and Virtual Highways at http://www.scienceofbetter.org/podcast/ .

The second and revised edition of Network Economics: A Variational Inequality Approach provides an updated treatment of network economics through the inclusion of new theoretical results and new applications, as well as problems for self-study purposes and/or for use in the classroom. This volume remains true to the first edition in that it provides a unified treatment of finite-dimensional variational inequalities, algorithms, and applications. Physical networks are pervasive in today's society in the form of transportation networks, telecommunication networks, energy networks, and financial networks, whereas mathematical networks provide a mechanism for studying a plethora of economic equilibrium problems through a common graphic structure. Network Economics establishes the connections among economic equilibrium problems through their network structure and demonstrates how the structure can then be used to address policy interventions, as well as to construct efficient numerical schemes for the computation of equilibria.The network framework provides not only a mechanism for the graphic representation of economic problems and a means for visualizing their similarities and differences, but, in addition, a novel theoretical approach. Problems treated include: congested transportation systems, oligopolistic market equilibrium problems, problems of human migration, and general financial and economic equilibrium problems. New applications covered in this second edition include environmental networks and knowledge networks.

The increasing complexity of economic problems, coupled with advances in numerical methods and computer architectures, have stimulated the growth and interest in computational economics. Accompanying this activity is the need for the unification, documentation and presentation of fundamental methodologies for use by researchers and practitioners. "Network Economics: A Variational Inequality Approach" makes a contribution in this direction by providing a treatment of the theory of finite-dimensional variational inequalities, algorithms and applications. The focus of the volume is on network economics.

Equilibrium is a concept used in operations research and economics to understand the interplay of factors and problems arising from competitive systems in the economic world. The problems in this area are large and complex and have involved a variety of mathematical methodologies. In this monograph, the authors have widened the scope of theoretical work with a new approach to previous work in variational inequality theory. While most classical work in this area is static, the introduction to the theory of projected dynamical systems will allow many real-life dynamic situations and problems to be handled and modelled. This text includes: a new theoretical approach, "projected dynamical system", which allows the researcher to model real-life situations more accurately; new mathematical methods allowing researchers natural, financial and human (real-life) situations in competitive equilibrium problems; and the computational and numerical methods for the implementation of the methods and theory discussed in the book. Stability analysis, algorithms and computational procedures are offered for each set of applications.

Despite significant achievements, thediscipline of supply chain management is still unable to satisfactorily handlemany practical real-world challenges.  The authors of Networks AgainstTime claim that a unified supply chain network analytics framework isneeded which should be able to handle optimization and competitive behaviorwhile also maintain relevance to many industrial sectors in which perishableproducts are prominent, from healthcare to food and from fashion apparel totechnology. ThisBrief provides a wide range of critical supply chain problems which aremodeled as generalized networks. Guidelines are provided to determine the arcmultipliers that capture perish ability of the product whether food,radioisotopes, or even highly perishable blood in healthcare over space andtime. Through case studies the authors portray the application of the modelsand algorithms to real-world sectors which illustrate the power of theframework in practice. The models and algorithms are fully described along withthe input and output data in the case studies. This level of transparency isuseful pedagogically as well as for future research and for applications inpractice.Researchersand practitioners in mathematics, in operations research and managementscience, operations management, as well as in economics and computer sciencewill find this book useful to gain a broader appreciation of the richness ofnetwork supply chain structures, processes, and applications. This book canalso be used by advanced undergraduate students and graduate students in thedisciplines noted above to familiarize themselves with methodologies and supplychain network models and applications.​​

This original book presents a new basis for environmental policymaking: environmental networks. This framework graphically simplifies the analysis of environmental problems and emphasizes the spatial nature of economic activity and pollution dispersion.The book first discusses the foundations of environmental economics before going on to apply the environmental network approach to different firm structures. The authors then extend the analysis to incorporate multiple products and pollutants, the presence of transaction costs, the availability of investment in production technologies, and the issue of noncompliance versus compliance. They also apply the network approach to pollution caused by transportation and assess the success of permits in limiting this. The authors then formulate integrated models, analyzing the use of permits and taxes in firms, producers, and consumers, as well as transportation and trade routes. This book will be of interest to students, researchers, practitioners, and policymakers in environmental and transport economics.

Transportation networks are essential to the functioning of societies and economies and provide the infrastructure for the movement of people and goods over space and time. The existence and utilization of transportation networks are fundamental to the modern age and the negative effects of congestion and pollution associated with their increasing usage demand urgent attention.This book cogently addresses the question as to whether transportation networks are sustainable: that is, can they last, given the growing demands on the network, on the one hand, and the desire to alleviate the associated negative impacts, on the other. Anna Nagurney answers the question positively by providing a rigorous foundation for the formulation, analysis, and computation of solutions to such problems through the use of appropriate policies ranging from tolls and tradable pollution permits to the design of the networks themselves.Sustainable Transportation Networks will be of great value to students, researchers, and practitioners of transportation studies, environmental economics, regional science, and urban planning.

The advent of the Information Age has transformed the ways in which individuals work, travel, and conduct their daily activity. Anna Nagurney and June Dong lay out the theory of supernetworks, networks that exist over and above existing electronic networks, in order to formalize decision-making in the Information Age. Supernetworks are conceptual in scope, graphical in perspective, and, with the accompanying theory, predictive in nature. In this book, the authors provide a unifying framework for the study of decision-making by a variety of economic agents including consumers and producers as well as distinct intermediaries in the context of today's networked economy. They provide the conceptual, analytical, and computational tools for the study of supernetworks. Their approach is rigorous and of sufficient generality and detail to give added insight into the behavior and structure of large-scale, interacting and competitive network systems, such as transportation, telecommunication, and financial networks. Areas studied include: supply chain networks with electronic commerce, financial networks with intermediation, telecommunicating versus commuting decision-making, teleshopping versus shopping decision-making, as well as transportation and location decisions. Case studies drawn from practice are provided for illustration purposes. Academics and practitioners in economics, business, and operations research along with management scientists, transportation and logistics researchers, computer scientists and applied mathematicians will find this book fascinating and useful.

Networks provide the foundation for the functioning of our societies and economies. Their study has had a long tradition in such fields as engineering, operations research, management science and computer science. More recently, the disciplines of finance and economics have come to be rich and fascinating sources of network-based problems and applications. This focused and refereed volume of contributions from leading international scholars provides a wealth of innovations in the study of financial and economic networks. The volume presents entirely new results: the conceptualization of the stock market as a graph, the evolution of financial systems as networks, the incorporation of electronic transactions in international finance (from a network perspective), new formalisms for the study of supply chains (as fluid models and in an network economic framework) and new applications of agent-based computational economics trade networks with intermediaries and worker-employer networks. Finally, trade networks in web-based caching are introduced. Financial applications covered include: portfolio optimization with transaction costs, integrated pension and corporate planning, evolutionary financial networks, international finance and electronic transactions as well as hedging instruments for transportation networks. Innovative approaches to economic networks are developed in the context of supply chain and distribution networks, a variety of trade (including web-based caching) networks and even worker-employer networks.A major addition to this exciting and important subject, Innovations in Financial and Economic Networks will be an invaluable resource for economists and the networks community, as well as researchers and students in computational economics and finance, operations research, management science, applied mathematics and computer science.

This book is the first to bring an economics perspective in a rigorous manner to complex decision-making in the management of supply chains. It provides the foundations for the modeling of the interrelationships among decision-makers in supply chains, ranging from manufacturers, distributors, and retailers, to the consumers, assuming individualized behavior. The models handle both competition and cooperation and provide the resulting product flows and prices in the chains. A unique network economics perspective is brought to the issue, setting the book apart from the numerous management and operations research volumes available. After an introduction of the theoretical foundations, the book extends and applies the theory to energy supply chains in the form of electric power generation and distribution networks. The relationships between electric power supply chains and transportation networks are vividly captured through theoretical results and the solution of practical examples. The book then explores environmental supply chain and financial networks with intermediation, which are interpreted as supply chains and also solved as such. Throughout, the underlying theme is that of transportation networks and how the relationships between supply chain networks and the more established theory of transportation network equilibria can be applied and exploited for logistic-type applications. Economists and transportation researchers will find the book's theory and applications of great interest. Operations researchers and management scientists as well as practitioners in business logistics will be interested in the book's methodological and practical tools.

The COVID-19 pandemic has vividly and dramatically demonstrated the importance of supply chains to the functioning of societies and our economies. The discussion in this timely book explores prominent issues concerning supply chain networks and labor. The readership is aimed to include students, researchers, practitioners, and policy-makers, interested in the wide range of topics presented in these pages. Labor has a particular focus as the driver behind supply chains, whether associated with food products, life-saving medicines and supplies, or high tech products that make innovation possible, just to name a few.  The impacts of policy interventions, in the form of wage bounds, and their ramifications, in terms of volume of attracted labor, product prices, product volumes, as well as profits, are explored. Profit-maximizing firms are considered (with relevant associated issues such as waste management in the case of the food sector, for example), but also non-profits, as in blood services, as well as humanitarian organizations engaged in disaster relief. The book is filled with many network figures, graphs, and tables with data, both input and output and includes an appendix that provides the foundations of the underlying mathematical methodologies used.The book offers strong evidence for the need to provide a holistic, system-wide perspective for the modeling, analysis, and solution of supply chain problems with the inclusion of the critical labor resources. A formalism using the prism of supply chain networks, which yields a graphic representation of supply chains, consisting of multiple stakeholders, is constructed. Models that capture the behaviors and interactions of single decision-makers as well as multiple decision-makers engaged in supply chain activities of production, transportation, storage, and distribution, are considered. The models capture many realistic constraints faced by firms today, as they seek to produce and deliver products, while dealing with competition, various constraints on labor, a variety of disruptions, labor shortages, challenges associated with proper wage-determination, plus the computation of optimal investments in labor productivity subject to budget constraints. The book provides prescriptive suggestions in terms of how to ameliorate negative impacts of labor disruptions and demonstrate benefits of appropriate wage determination.

This book lays the foundations for quality modeling and analysis in the context of supply chains through a synthesis of the economics, operations management, as well as operations research/management science literature on quality. The reality of today's supply chain networks, given their global reach from sourcing locations to points of demand, is further challenged by such issues as the growth in outsourcing as well as the information asymmetry associated with what producers know about the quality of their products and what consumers know. Although much of the related literature has focused on the micro aspects of supply chain networks, considering two or three decision-makers, it is essential to capture the scale of supply chain networks in a holistic manner that occurs in practice in order to be able to evaluate and analyze the competition and the impacts on supply chain quality in a quantifiable manner.This volume provides an overview of the fundamental methodologies utilized in this book, including optimization theory, game theory, variational inequality theory, and projected dynamical systems theory. It then focuses on major issues in today's supply chains with respect to quality, beginning with information asymmetry, followed by product differentiation and branding, the outsourcing of production, from components to final products, to quality in freight service provision. The book is filled with numerous real-life examples in order to emphasize the generality and pragmatism of the models and tools. The novelty of the framework lies in a network economics perspective through which the authors identify the underlying network structure of the various supply chains, coupled with the behavior of the decision-makers, ranging from suppliers and manufacturers to freight service providers. What is meant by quality is rigorously defined and quantified. The authors explore the underlying dynamics associated with the competitive processes along with the equilibrium solutions. As appropriate, the supply chain decision-makers compete in terms of quantity and quality, or in price and quality. The relevance of the various models that are developed to specific industrial sectors, including pharmaceuticals and high technology products, is clearly made. Qualitative analyses are provided, along with effective, and, easy to implement, computational procedures. Finally, the impacts of policy interventions, in the form of minimum quality standards, and their ramifications, in terms of product prices, quality levels, as well as profits are explored. The book is filled with many network figures, graphs, and tables with data.

Financial analysis is concerned with the study of capital flows over time and space. This book presents a new theory of multi-sector, multi-instrument financial systems based on the visualization of such systems as networks. The framework is both qualitative and computational and depends crucially on the methodologies of finite-dimensional variational inequality theory for the study of statics and equilibrium states and on projected dynamical systems for the study of dynamics and disequilibrium behavior. Moreover, it adds a graphical dimension to the fundamental economic structure of financial systems and their evolution through time.
