Through dispersing runway taxiway and apron, discrete element map to Petri net basic element, build surface activity model based on Petri net. The paper build model of apron activity by Petri net theory, use Cpntools simulate real apron activity, analysis and assess real activity efficiency of aircraft, prove validity of model and improve apron efficiency.
