Integrating Information Flow and Physical Flow Layers in Transportation Networks
This paper proposes a new approach for modeling transportation systems. The proposed multi-layered modeling approach involves explicitly modeling information flow and the interactions between the physical and information flows. To illustrate this idea a simulation model of a runway is built using colored Petri nets. The model consists of two interacting layers: physical and information layers. The physical layer models the aircraft movements while the information layer deals with control and management of the air traffic. Aircraft communicate with the information layer to get clearance for takeoffs and landings. Communication links connect the two layers and carry clearance messages as well as other pertinent information. To investigate the impact of disruptions in the flow of information on system performance a number of scenarios are considered. Deterioration in system performance is measured in terms of average and maximum delays to the aircraft. Simulation reveals where the system is more sensitive to these information flow delays.
