Missile Weapon Effectiveness Evaluation And Cooperative Combat Task Planning Method

As an effective weapon to safeguard maritime strategic interests,anti-ship missile has been highly valued by countries all over the world.After nearly a century of development,anti-ship missile has the characteristics of automatic control,high guidance accuracy and strong penetration capability.With the development of artificial intelligence,big data and other technologies,the anti-ship missile weapon system will develop in the direction of clustering,intelligence and autonomy.In order to meet the new challenges and new requirements of complex military tasks in the future,support the cooperative combat of anti-ship missile system,this dissertation conducts in-depth research on the dynamic evaluation of anti-ship missile combat effectiveness,cooperative combat path planning,continuous combat task assignment and task planning technologies.Research contents of this dissertation are as follows:Aiming at the dynamic evaluation of missile combat effectiveness in the process of anti-ship missile and surface ship attack and defense confrontation,the effectiveness evaluation method based on probability finite combination state machine is studied.The comprehensive model of enemy countermeasures and the missile survivability model under complex sea conditions are established,and the operational effectiveness index system of anti-ship missile is constructed and the sub-effectiveness evaluation of anti-ship missile is realized.A probabilistic finite combination state machine modeling method is proposed to solve the problem of combined representation of anti-ship missile’s own state and encounter events,and the dynamic evolution model of the effectiveness of key nodes in missile combat is constructed.By combining the missile sub-effectiveness evaluation model,the problem of dynamic characterization and evaluation of the anti-ship missile combat effectiveness is solved.To meet the requirements of sea skimming cooperative penetration in the process of multi-missiles strike warship formation,a method based on fast path search and space-time cooperative path planning is studied.The constraints of range,maneuver,flight speed,time coordination and space coordination are deeply analyzed,and the anti-ship missile path planning model and multi-missiles space-time cooperative combat model are established.An improved rapidly-exploring random tree method based on rule search and cross entropy optimization is proposed to solve the problem of rapid generation of missile combat path.The cooperative decoupling strategy of speed control and path control is designed,and a space-time cooperative combat path planning algorithm for multi-missiles sea skimming penetration is proposed.The effectiveness and feasibility of the proposed method are verified by the simulation experiment of multi-missiles cooperative combat path planning.Aiming at the continuous combat task assignment problem of missile system to warship formation,the solution method of multiple constraints and nonlinear combinatorial optimization problem based on cross entropy is studied.An improved sparse least squares support vector regression machine is proposed to express the nonlinear mapping between effectiveness index and combat effectiveness,the increasing evaluation function of damage capability when multiple missiles cooperate to attack ship target is designed,so as to realize the damage effectiveness evaluation of multi-missiles cooperation.Considering the dynamic factors such as assignment availability,missile inventory and missile damage capability,and a continuous combat task assignment model is established.Based on the cross-entropy theory,the nonlinear and non-convex optimization model is transformed into a convex optimization problem,the optimization solution process is deduced in detail,and a continuous combat task assignment method based on cross entropy is proposed.The simulation of continuous combat task assignment and the evaluation of task assignment scheme are carried out to verify the effectiveness of the proposed model and method.Aiming at the task planning of anti-ship missile system under coupling effect,the task planning method based on improved simulated annealing algorithm is studied.Considering the constraints of missile availability,target allocation quantity and multi-bases,combined with missile effectiveness evaluation and continuous combat task assginment model,the combat task planning model of anti-ship missile system is established.An improved simulated annealing algorithm is proposed to solve the coupling problem of task assignment and task scheduling in the combat application of anti-ship missile.Further,combined with the clustering algorithm,the task planning problem in dense scenario is solved,the availability evaluation criteria are designed to solve the task planning problem in dynamic scenario.Combined with effectiveness evaluation,cooperative path planning and continuous combat task assignment,the comprehensive simulation experiments are carried out to prove that the model and method proposed in this paper can provide decision-making support for the optimization of combat effectiveness of anti-ship missile system.The missile weapon combat effectiveness evaluation and missile group cooperative combat task planning technologies are explored and studied in this dissertation.The relevant research results provide an effective reference for the solution of missile effectiveness evaluation,cooperative path planning,combat task assignment,task planning and so on,and have certain theoretical research significance and engineering application value in promoting the application of missile weapon system to complex military combat tasks.
