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).

  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?
