先期毁伤原则下武器单元的射击时机分配

Shooting Time Assignment of Weapon Units based on Earlier Damage

以先期毁伤为原则,首次对武器单元的射击时机分配问题进行数学建模。提出一种使毁伤概率密度在时间上靠前分布的武器单元射击时机分配模型,在保证指定瞬时之前以期望概率毁伤目标的前提下,合理分配各武器单元的射击时机,实现对目标的尽早毁伤。根据射击时机分配模型中约束函数的单调性特点,提出一种改进的连续域蚁群算法,使算法自变量满足约束条件的"优良区域"开始搜索,采用搜索窗口平移的方法逐步寻找最好解,提高了算法的搜索速度。实例分析验证了模型和算法的有效性。

Based on the principle of earlier damage, a shooting time assignment model is proposed. The damage probability density can distribute over the former time. In the presupposition of that the target can be damaged with expected probability before specific time, the weapon units＇ shooting times are scheduled to damage the target earlier. According to monotonicity of restriction function, an improved continuous ant colony algorithm is presented. The solution is searched from ＂good area＂ of each variable, in which the restriction can be satisfied easily, so the optimal solution can be found more rapidly. The effectiveness of the model and the algorithm is illustrated with examples.
