| Airport ground support is a complex discrete event system,which requires the cooperation of multi-professional and multi-equipment man-machine systems.An efficient and complete mission support method can ensure the fighter plane taking off in the shortest time under the optimal condition,and greatly improves the combat effectiveness.The guarantee operation needs strict operation rules,which is related to the safety of fighter planes,but also need to carry out reasonable resource allocation to ensure the rapid formation of combat effectiveness.Therefore,how to arrange the preflight support operation flow in the shortest time under the optimal allocation of the situation to complete the support task is crucial.In order to improve the efficiency of resource allocation,the simulation of airport support task will be carried out.For as many as a dozen security operations(gas,charging,oxygen,ammunition,hanging bomb,tank and so on),this paper focuses on the vehicle routing problem in the process of ammunition and bomb hanging in the process of operation process simulation based on discrete event.This paper studies the background and the related research in the field of machine service protection.Besides the paper analyzes the key technology of the vehicle routing problem,discrete event simulation,eMPlant simulation software.Then I elaborates the content of airport support tasks,processes and characteristics.Nextly I design of the improved genetic algorithm to solve the vehicle routing problem of ammunition.Under the basic research,I establish the simulation model of transporting process and discrete event hanging process.Finally,I use the eM-Plant simulation software to do system simulation of all support tasks procedures and get the shortest time of complete process of the hanging bomb.Then I analyze the bottleneck of the process and put forward the optimization solution to solve the bottleneck problem,and build the software system of the airport ground support task planning. |
