Supernetworks

Supernetworks play a crucial role in our interconnected world, influencing daily choices and economic functions. This study explores the concept of a supernetwork, comprising various nodes, links, and flows that extend beyond traditional networks. We examine challenges in decision-making, including centralized vs. decentralized approaches, competition, and equilibrium strategies. The rise of telecommuting, with its benefits like reduced traffic and improved productivity, highlights the complex interplay within supernetworks. Our research also considers the implications on land use and environmental factors, providing insights into future applications and decision-making criteria.

  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
