Model for Computing Destruction Probability of Runway and Calculating Precision Analyzing

For overcoming the limitation of the current models for computing the destruction probability of the runway(DPR),which only considers the airplane flying-off and landing along the runway,a new model was proposed,which also considers the airplane flying-off and landing along a direction slanting with the runway.This model takes advantage of Monte-Carlo method,after simulating the impact point of the sub-munitions and randomly sampling a series of rectangles having the same size with the min leave window(MLW),the DPR was computed by judging the numbers the airplane blocked among the simulations.The computational results show that: the current models make the result distinctly lager,and this method is more reasonable and scientific.The calculating precision of our new model was analyzed.
