Abstract: Aiming at the problem of kill-chains design, a modeling and optimization method of kill chains based on AGE-MOEA(Adaptive geometry estimation based multi-objective evolutionary algorithm) is proposed. Based on the idea of kill chain closure, combined with the OODA cycle theory, and based on the traditional weapon target assignment model, the multi-objective optimization mathematical model of kill chains design was constructed, so as to realize the mathematical representation of kill chains design problem. The model comprehensively considers three kinds of weapons, which are used for reconnaissance, command and attack respectively, and takes the maximum attack efficiency, minimum weapon consumption and minimum damage threat as the objective functions, and takes the equipment use constraints, kill chain relation constraints and damage threshold constraints as constraint conditions. The algorithm flow of kill chains optimization design based on AGE-MOEA is proposed to solve the multi-objective optimization mathematical model of kill chains design. Through numerical experiments and kill chain design experiments in air defense and anti-missile combat scenarios, the results show that the proposed method can simultaneously pursue the optimization of attack efficiency, weapon consumption and damage threat on the premise of ensuring that all kill chains of each target are closed, and obtain a kill chain solution, which can form distributed lethality. The scientificity of the multi-objective optimization mathematical model of kill chains design, the effectiveness of AGE-MOEA algorithm in solving kill chains design problems and the feasibility of kill chain design method in practical military operations are verified.
