The safety analysis of flight landing based on Time Petri Net

This paper mainly discusses the airport task flow safety problems induced by time factors, based on the Time Petri Net (TPN) method. We introduced the characteristics of an airport accident, and the method of TPN to analyze the flight landing task flow. The more detailed steps are shown as follows. Based on the characteristics of airport landing task flow, this paper introduced a plan task safety analysis method. The method can compute the task system effect probability which is induced by the time factor, also can located the key events im pacting the task, and proposed the measures and advice to improve the task system safety. This paper shows the task safety analysis approach by a flight landing task flow example based on TPN methods. The result shows that the method is feasible and efficient. In summary, the ultimate of this paper is to introduce an efficient method to analyze the airport task flow safety.
