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.
