Pickup and delivery transport
  • Pickup and Delivery Transportation Problem
    freight has to be transported from a source to a
    destination location respecting specified time
    intervals on a transport network with limited
    capacities and speeds.
  • Limited capacities lead to conflicts.
  • ?Malfunctioning resources (infrastructure and
    transport resources).

  • Research questions
  • Approach and results
  • Future work

Applications
  • AGV containerterminals
  • Taxiing of airplanes at an airport
  • Inlandshipping
  • Problem description
  • Applications

5
Literature
  • Mixed Integer Programming (Savelsbergh and Sol,
    1995)
  • Context-Aware Routing (Kim and Tanchoco, 1991)
  • Reduction to Job Shop Scheduling with blocking
    (Hatzack and Nebel, 2001)
  • Survey of techniques for scheduling with
    uncertainty (Davenport and Beck, 2000)
  • Problem description
  • Applications
  • Literature
  • Research questions
  • Approach and results
  • Future work

6
Research questions
  • What information is necessary to obtain efficient
    planning methods?
  • What happens when varying workload, number of
    agents (scalability), incident level (normal to
    extreme circumstances, robustness)?
  • What is the relation between performance and
    characteristics of the transport network?
  • Problem description
  • Applications
  • Literature
  • Research questions
  • Approach and results
  • Future work
