  1. Supernetworks Qiong June Dong School of Business

  2. Funding provided by • National Science Foundation • Faculty Enhancement Grant

  3. Networks are pervasive in our daily lives and essential to the functioning of our societies and economics.

  4. What is a Supernetwork? A Supernetwork is a network, consisting of nodes, links, and flows, that is over and above existing networks. Source:http://supernet.som.umass.edu

  5. Challenges • Decision Making • Centralized vs. Decentralized • More alternatives • Complexity • Large scale Competition • Equilibrium vs. Optimization

  6. Nash Equilibrium

  7. Commuting Telecommuting

  8. Why Telecommuting? • Reduce traffic congestion • Reduce emissions • Land use • Human resource policy

  9. Number of telecommuters increased from 4 million to 23.6 million in the past decade. Recent legislation permits federal employees to select the telecommuting option 72.4% reported that working at home slightly or greatly increased productivity Telecommuting

  10. Questions • Telecommute or Commute? • How often? • What’s the impact on traffic? • What’s the impact on land-use? • What’s the impact on environment?

  11. A Conceptualized Supernetwork of Commuting vs. Telecommuting

  12. Be Aware of Paradoxes A decrease in demand on a supernetwork with a zero emission link may result in an increasein emissions. Adding a new path which consists solely of a zero emission link and which shares no links with any other path may result in an increase in emissions.

  13. What do we see? • The importance of the incorporation of Network Topology, Cost and Demand Structure, Users Behavior. • The interconnectivity among distinct network systems

  14. A Supernetwork may have both virtual and physical links A Supernetwork may be multitiered and multilevel. Decision-makers may have distinct criteria such as time, monetary cost, opportunity cost, risk, and/or safety.

  15. Applications of Supernetworks • Telecommuting / Commuting decision making • Teleshopping / Shopping decision making • Supply Chain Networks with E-commerce • Financial Networks with Electronic Transactions

  16. Teleshopping vs. Shopping

  17. Supply Chain - Transportation Supernetwork Representation Source: http://supernet.som.umass.edu
