A Petri-net modeling approach for airport apron traffic dynamics
Xinping Zhu · 2017
An approach using Petri net for airport apron dynamics modeling is presented. It is based on top-down, modular and resource-oriented methodology which makes the stepwise modeling possible. We divide the apron traffic system into disjoint zones and the basic net model is constructed by graph theory. The colored timed Petri net is utilized to model the traffic dynamics in each apron zones, and also the outside control specification from controller is integrated through introduction of control place into the model. Furthermore, the refinement procedure is provided for the replacement of vertices and arcs in basic net by modular Petri net model. And also, method for apron conflict control logic modeling is proposed. Finally, a modeling example is used to demonstrate our proposed method.
