根据多目标决策理论，从系统的角度出发，提出了防御权系数问题，并在此基础上研究对空攻击任务的分配策略，给出了效度最大攻击任务分配策略和重点防护目标优先攻击任务分配策略，并引入攻击强度阀值概念，对这两种分配策略进行了改进，最后给出了具体算法。 According to the theory of multi-objective decision-making, from the system point of view, this paper proposes the problem of defensive weighting coefficient, and on this basis, it studies the allocation strategy of air attack mission, and gives the strategy of the most efficient attack mission assignment and the key attack target priority attack Allocation strategy, and introduces the concept of attack strength threshold, these two allocation strategies have been improved, and finally given the specific algorithm.
