摘要: 对地打击目标与武器类型复杂多样,其武器-目标分配问题难度较大,研究不足,而合理的武器-目标分配方案,可优化资源配置,用最小的代价获取最大的战场收益。为此,构建相应数学模型,并针对采用遗传算法进行解算时收敛速度慢,甚至无法得出可行解等问题,设计了一种变量取值控制方法。该方法通过约束和控制初始种群个体中变量的取值范围来缩小搜索空间,提高搜索效率;通过改进变异策略扩大变量取值范围,确保解的质量。仿真结果表明,改进的遗传算法能有效地解决大规模对地打击武器-目标分配问题,且性能较优。

Abstract: Research on weapon-target assignment (WTA) of ground target attacking is very difficult due to a wide variety of targets and weapons. A reasonable WTA scheme is developed to optimize the allocation of limited resources, which brings the maximum battlefield gains with minimum costs. For this reason, a mathematical model is established, and the genetic algorithm is used to resolve the optimal result of weapon-target assignment. But the convergence rate of genetic algorithm is slow and can't even give a feasible solution in solving WTA. A state variable control method is designed to overcome the insufficient of the genetic algorithm. The proposed method can reduce the search space and improve the search efficiency by restraining and controlling the value range of the initial population variables, and ensure the quality of the solution by improving the mutation strategy to expand the value range of the variables. The simulated result shows that the improved genetic algorithm can solve the WTA problem of attacking the ground targets on a large scale effectively.
