Ship Self Defense System Modeling And Simulation Based On Petri Net

In the face of anti-ship cruise threat, ship self defense system has an automatic, rapidresponse, multiple target engagement capability, so ship self defense system is essential tomodern ship. Ship self defense system integrated design includes the following two keyproblems: how to improve the system response speed and self defense resource selection anduse problem. Developments ship self defense system modeling and simulation, discovers thefactor that restricts the combat effectiveness of ship air self defense system is very importantto accelerating design and optimization of ship air self defense system.The paper first analyzes the composition of ships air self defense system and the divisionof tasks, ships air self defense system can be divided into three modules: probing perceptionmodule, command and control module and weapons modules. Introduced the general processof the modern ship air defense combat, and give the ship air self defense combat taskpartitioning hierarchical model. Analysis the radar detection, and chose a radar detectionmodel based on radar equation. Analysis the weapon assignment process, and put forward aweapon allocation method based on attack list. Give the attributes or the index of the target,sensors and weapon selected in this paper. According to the analysis of the time delay of eachmodule, give the determine method of the time delay of each module.According to the tasks division of each module, analysis the information flow betweenthe modules and establish corresponding information flow model. Based on the informationflow model, give the Petri net model of the modern ship air self-defense system.Carry out the simulation of the air self-defense combat. Aiming at the parameteroptimization problem, carry out the simulation of the air self-defense combat using thedynamic simulation method, from the angle of target, radar and weapon, analysis the impacton the simulation results of different system configuration scheme. The analysis in this paperprovides an assessment method based on Petri net to assess the design of the systemcomposition and configuration, the operation capability, etc. The paper is of some referencevalue for researches in future.
