Harvard Business Review Press Making Markets: How Firms Can Design and Profit
Book SynopsisMarkets are transitioning from place to space - but as the collapse of the initial B2B boom demonstrated, the journey won't be easy. Pioneering market makers from eBay and British Petroleum to the Dutch Flower Auctions and ChemConnect are leading the way to create new value through markets. Their experiences make two things increasingly clear: success in the marketspace will require new ways of operating, and participation won't be optional. Ajit Kambil and Eric van Heck - respected authorities on electronic markets - argue that online auctions and exchanges will soon be an essential part of business practice. They explain why companies must adopt electronic markets now if they hope to compete in the future. And they prove that success lies not in achieving "first-mover" advantage in new markets, but in creating winning strategies to design and use markets to manage the supply chain, connect with customers, increase efficiency, and make decisions.Based on the authors' decade-long study of nearly one hundred successful and failed electronic markets in the United States, Europe, and Asia, the book reveals how market makers are rewriting the rules of commerce. They offer a strategic blueprint for designing, implementing, and profiting from electronic markets. "Making Markets" shows how companies can: creatively use markets in procurement, resale, and clearance, and in more novel applications such as prediction, risk management, and decision making; design, deploy, and stimulate the successful adoption of online auctions and exchanges; utilize technology to support - not replace - human interaction; leverage information to become more profitable buyers and sellers; innovate in trade processes from pricing, payment, and authentication to logistics and product representation; and, grow markets through partnerships, alliances, and mergers.This highly practical guide will help companies create the ultimate market: one that captures the feel and trust of a physical community but leverages the power and efficiency of technology to benefit all participants. Ajit Kambil is Associate Partner and Senior Research Fellow at Accenture's Institute for Strategic Change. Eric van Heck is a Professor at Erasmus University's Rotterdam School of Management, The Netherlands.Table of Contents1 Seizing the Value of Markets 2 From Place to Space 3 Making Markets Work 4 Auctions: The Devil Is in the Details 5 Using B2B Markets in the Supply Chain 6 Using Markets Creatively 7 Market Tactics 8 Dynamic Market Strategies Epilogue: A Call to Action

ISTE Ltd and John Wiley & Sons Inc Advanced Mobility and Transport Engineering
Book SynopsisMultimodal transport network customers need to be directed during their travels. A travel support tool can be offered by a Multimodal Information System (MIS), which allows them to input their needs and provides them with the appropriate responses to improve their travel conditions. The goal of this book is to design and develop methodologies in order to realize a MIS tool which can ensure permanent multimodal information availability before and during travel, considering passengers’ mobility. The authors propose methods and tools that help transport network customers to formulate their requests when they connect to their favorite information systems through PC, laptop, cell phone, Portable Digital Assistant (PDA), etc. The MIS must automatically identify the websites concerning the customer’s services. These sites can, in fact, represent transport services, cultural services, tourist services, etc. The system should then be able to collect the necessary travel information from these sites in order to construct and propose the most convenient information according to the user’s requests.

Book SynopsisThis book examines multicast technology and will be a key text for undergraduate engineering students and master students in networks and telecoms. However, it will be equally useful for a wide range of professionals in this research field. Multicast routing was introduced with the advent of multiparty applications (for example, videoconferencing on the Internet) and collaborative work (for example, distributed simulations). It is related to the concept of group communication, a technique introduced to reduce communication costs. The various problems of multicast routing on the Internet are examined in detail. They include: group membership management, quality of service, reliability, safety, scalability and transport. Throughout the text, several protocols are introduced in order to analyze, compare and cover the various aspects of multicast routing.Table of ContentsPreface xvii Chapter 1.
