| Abstract: | By using stochastic Petri net（SPN）,runway system constraint equations are built,and then a steady-state probability expression of the system in various states are established in the basis on Markov chain.Furthermore,by changing the transition trigger rate and analyzing the changes of runway utilization,it proved that the model is reachable,unbounded and live. |
| Keywords: | runway utilization rate stochastic Petri net markov chain steady-state probability |
