有效武器目标分配(WTA)是防空阵地的核心。分析了目标毁伤收益、武器损伤关键战术指标因素,提出基于效费比的WTA评价标准,建立了针对多目标的WTA模型,并研究了用遗传算法求解模型的方法。该遗传算法通过设计一种武器目标分配的染色体编码,利用最优保存策略选择运算、均匀交叉运算、非均匀变异运算来求解。仿真结果验证了模型的合理性和算法的有效性。 相似文献

武器-目标分配问题是一种NP问题。结合武器-目标分配问题的特点,提出了一种求解武器-目标分配问题的启发式方法。首先给定问题的初始解作为当前最优解,然后采用多点调整方法在当前最优解的邻域内搜索最优解,其后采用重复迭代策略逐步改进初始解,直到得到较好的近似解。实验研究发现,多点调整方法只是一种局部优化方法,由不同初始解出发获得的近似解对应目标值可能不同。把多起点策略、多点调整方法和重复迭代搜索策略相结合,可得到求解武器-目标分配问题的一种有效方法。实验结果表明,提出的启发式方法计算所得解的质量较高,是求解武器-目标分配问题的一种有效方法。 相似文献

对武器-目标分配(WTA)问题的研究现状与进展进行了总结与述评.介绍了WTA问题的概念、基本模型、数学性质以及WTA问题研究的基本内容.目前WTA问题的研究内容主要集中在模型研究与算法研究两个方面.模型研究以静态模型的研究为主,但动态模型的研究还不够深入;算法研究则主要采用智能算法对WTA问题进行求解.目前基本上已经解决了小规模的静态WTA问题,但尚未有效解决大规模的动态WTA问题. 相似文献

当前,对作战仿真在广度和深度上提出了更高层次的需求,即在扩大仿真规模的同时,更加注重仿真精度的提高。通过分析传统平台级CGF(Computer Generated Forces)模型在满足仿真需求方面的不足,建立了基于战斗岗位的武器平台CGF模型结构,研究了作战过程中影响战斗人员决策与操作行为的主要行为因素及其影响机制,并将其引入到岗位模型。最后,实现了考虑个体行为因素的坦克CGF炮长岗位模型,并对所建立的坦克炮长岗位模型在某作战仿真系统中的应用效果进行了分析。 相似文献

An analysis of US assessments of Germany's development of armored warfare illustrates the problems that intelligence agencies face as they attempt to understand military innovation. The covert nature of German Army's tank research in the years immediately following World War I limited the number of indicators of Berlin's interest in armored warfare. Similarly, the United States possessed at best a fragmentary picture of German experimentation with armor. By the outbreak of World War II, however, US military attaches had nonetheless developed an accurate understanding of German concepts of armored warfare. If the United States is to avoid strategic surprise in the future, it must cultivate intelligence sources and employ considerably different methods from those of the Cold War. 相似文献

This paper investigates the multivariate Polya distribution (MPD) for application in combat models for which enemy targets must be randomly assigned to fighting units. Six sets of actual combat data motivate the allocation model. Scenarios include air‐to‐air combat, tank, and submarine warfare. Goodness of fit tests are derived which verify the validity of the MPD, and reinforce the notion that multinomial allocation is too simplistic for such combat models. Simulations to determine optimal allocations for minimal combat cost are applied in order to illustrate the role of the MPD in combat modeling. © 2001 John Wiley & Sons,Inc.

What explains the pace at which militaries adopt new technology? We argue that the hierarchical structure and unique expertise requirements of military organizations combine to empower select individuals as ‘gatekeepers’ of innovation. These individuals acquire beliefs throughout their military careers regarding the nature and means of warfare that act to shape their attitudes towards new military innovations. By filtering, sidelining, and ignoring competing sources of advice and information, these officers actively inhibit the adoption of new, often advantageous, innovations. We develop this argument through the analysis of two cases: the delayed acquisition of breech-loading and repeating rifles by the Union Army during the American Civil War, and the failure of the US Army to adopt an adequate heavy-type tank in World War II. 相似文献

Hybrid warfare is the latest of the terms/concepts that have been used within the defence community in the last three decades to label contemporary warfare. It has been officially adopted in the core strategic documents of NATO, EU and national governments and has already inspired many articles, policy papers and books; however, this paper is unique in the sense that it analysis the hybrid warfare concept through the lens of strategic theory. It is argued that hybrid warfare does not merit the adoption as a doctrinal concept. Strategic theory instead, which lies at the nexus of all dimensions of warfare, provides a better viewpoint to approach contemporary warfare. It concludes that efforts should be directed towards exploring warfare under the light of eternal principles instead of proving the emergence of new types of warfare. 相似文献

This paper studies combat between two homogeneous forces modelled with variable-coefficient Lanchester-type equations of modern warfare with supporting fires not subject to attrition. It shows that this linear differential-equation model for combat with supporting fires may be transformed into one without the supporting fires so that all the previous results for variable-coefficient Lanchester-type equations of modern warfare (without supporting fires) may be invoked. Consequently, new important results for representing the solution (i.e. force levels as functions of time) in terms of canonical Lanchester functions and also for predicting force annihilation are developed for this model with supporting fires. Important insights into the dynamics of combat between two homogeneous forces with such supporting fires are discussed. 相似文献
