The method of searching for a crushed aircraft with dynamic model and 0???1 programming model

摘要

With the economy growing rapidly, as one of the means of transportation, the aircraft has played a significant role. But, there is a feature of the aircraft that if it happens to be faced with an air crush, the passengers from the airplane will merely be alive. So building a generic mathematical model to seek for the crashed plane is urgent. In this paper, the aircraft's rescuing mission is made up of two sections including determining the position where the aircraft drops into the sea, which also is the center of the searching area and the plan that how to rescue it by the equipment. The dynamic models expressed by the differential equations are introduced to simulate the flight path in the first section. In order to achieve the optimal allocation of searching and rescuing devices, the 0???1 programming model aiming at minimizing time is adopted to solve the searching task on the surface of the sea. And the searching plan is operated in the area solved though the position in the first section. What's more, the simulation experiments in this paper confirm that the model we design is an excellent generic model for the plane's searching task, which has a guiding role for future work.
