Research On Model Framework Of Combat Behavior Decision For Fighter Aircraft Based On Script

The model of airfight decision is the brain of the system of airfight simulation.The method chosen in the model of airfight decision is the hardcore of the simulation of airfight, determine the reliability of the result of simulation.Thus,studying the model of airfight decision is very important for constructing the system of airfight simulation.The mechanism of script has the ability of executing dynamicly,suit for complex states space,especially for the airfight decision simulation of fighter aircrafts.The thesis is based on the model framework of Sim2000.SMP2,using UML statecharts diagram to establish the concept model framework of airfight decision,using UML activity diagram to describing the process of airfight decision,defining the rules of transforming UML activity diagrams to python scripts,and get the script successfully by the rules.The thesis takes the simulation of airfight as the research background, and focuses on the research the model framework of airfight decision. The contents and innovations are summarized into the following parts:(1) Establish a model framework of airfight simulation based on Sim2000.SMP2 and the mathematic model of airfighter aircraft, and analyse the principles of firecontrol and the conditions of weapons launching in airfight.(2) Study the multi-dimension state space and order space,and propose the model framework of airfight decision.(3) Establish a concept model framework of airfight decision based on the Finite State Machine,propose an original model system of decision modeling based on UML activity diagrams,and describe and analyse the process of airfight decision using activity diagrams.(4) Define the rules of transforming UML activity diagrams to python scripts,get the python script of airfight decision through the transforming rules,and validate the framework through simulation experimentation.
