1
Automated Transport Planning using Agents Leon Aronson, Roman van der Krogt, Cees Witteveen, Jonne Zutt
2
CABS project Design and evaluation of heuristics for multi-agent systems that cooperatively execute complex tasks. Testing the efficiency of a distributed approach, e.g. compare to centralistic approach from optimization theory.
3
Transportation domain Generality: AGV terminal, Schiphol airport, Taxi cabs, Trucks. Flexibility: dynamics, incident management, replanning. Hierarchical agent-based model. Integration of planning and replanning (dealing with incidents).
4
Characteristics bobtailing empty rides drop-and-pick incidents time-windows penalties cost function home locations
5
Architecture STRATEGIC PLANNER order assignments status reports TACTICAL PLANNER orders cost function INFRASTRUCTURE time and distance data routing acceptance routing data
6
Strategic Layer Responsible for assigning orders to transport agents such that the whole is efficient and reliable. Advantage: does not have to bother with planning details.
7
Strategic planning Agent selection: trade-off between minimizing slack and maximizing slack. Redistribution of orders: remove scheduled orders for a group of agents, then try to reschedule after sorting them according to a heuristic used for the bin-packing problem.
8
Tactical Layer Responsible for executing orders assigned to it, using the infrastructure and handling incidents. Communicates deviations from assignments to strategic planner.
9
Tactical Planning Uses a variant of D* [Stentz] algorithm used for robot path planning. Traffic-aware cost function. Smart infrastructure: roads and crossings provide route information of all transport agents.

Example What kind of example would be usefull?
