谈消防部队会计监督职能的发挥

全国消防部队先后在各级建立了财务集中核算中心,按照统一的财务规章制度对本级及其所属单位一切经费进行集中核算、集中监管。但是,现行核算中心会计监督职能的发挥仍存在一些不足,文章对此进行了分析。并提出强化消防部队会计监督职能的建议。     

基于蚁群算法的舰艇编队多目标识别模型

现代海战中,舰艇编队面临的威胁目标复杂多样,正确识别目标是做出准确的军事决策的前提。基于蚁群算法的并行最优化特点,引入近邻函数,将目标识别问题转化为最优化聚类问题,提出了一种新的多目标识别算法。实验结果表明此方法是有效的,具有一定的军事现实意义。     

基于险度函数的装备供应链库存风险损失度量

目前,对供应链库存风险损失的定量研究比较少,而定量研究中鲜有对风险偏好变化问题的研究,因此首先分析了各种风险度量方法,通过比较采用了险度函数作为对装备供应链风险损失的度量方法;然后,结合装备供应链实际,提出了定常风险偏好特性险度函数和可变风险偏好特性险度函数的适用范围,以及装备供应链库存风险损失度量的损失水平值,并给出了装备供应链库存风险损失度量函数;最后,通过算例进行了验证.实验结果表明:行为人的不同风险偏好特性会对同一事态产生不同的预判,进而可能影响对风险的决策,这是符合客观现实的.     

SDI,NATO, and the Social Composition Function

The strategic defense initiative (SDI) intends to renew the leadership of the USA on the western alliance. The initiative takes place in a period when a summation technology prevails for the aggregation of contributions of NATO allies. We investigate if SDI induces a shift in Hirshleifer’s social composition function. Panel data tests over the period 1970–1990 do not confirm any break toward a best-shot aggregator. SDI does not alter the core of deterrence. It is indeed a public good at the US level but not at the NATO level, where, it is one of the joint products of the alliance. We also investigate the lessons to be drawn for the current debates on ballistic defense.

The sixteenth-century antecedents of special operations ‘small war’

The first conceptual, theoretical treatises about small war (la petite guerre) as special operations appeared only from the middle of the seventeenth century. The term is not used in the eighteenth-century sense of ‘special operations’ in older sources. The supposed absence of any treatment of the subject is surprising considering the obsession with the ‘art of war’ in the Renaissance, but other authors attribute it to a supposed antinomy between chivalric ideals and irregular warfare. But the absence of explicit manuals on the subject is not evidence of absence of advanced reflection on this kind of operations in the Middle Ages and in Early Modern times. We should thus look elsewhere, in other genres, for writings that contain and pass on military knowledge. Epics, romances, educational and military treatises, and memoirs in fact contain elements of a theory of special operations, even though these genres differ from our conception of rationality inherited from the Enlightenment.     

Introduction: Exploring the jungle of terminology

When twentieth-century authors wrote about ‘partisan warfare’, they usually meant an insurgency or asymmetric military operations conducted against a superior force by small bands of ideologically driven irregular fighters. By contrast, originally (i.e. before the French Revolution) ‘partisan’ in French, English, and German referred only to the leader of a detachment of special forces (party, partie, Parthey, détachement) which the major European powers used to conduct special operations alongside their regular forces. Such special operations were the classic definition of ‘small war’ (petite guerre) in the late seventeenth and in the eighteenth centuries. The Spanish word ‘la guerrilla’, meaning nothing other than ‘small war’, only acquired an association with rebellion with the Spanish War of Independence against Napoleon. Even after this, however, armies throughout the world have continued to employ special forces. In the late nineteenth century, their operations have still been referred to as prosecuting ‘la guerrilla’ or ‘small war’, which existed side by side with, and was often mixed with, ‘people's war’ or popular uprisings against hated regimes.     

陆军作战仿真模型组件化设计

陆军作战仿真是一个复杂的系统工程,仿真所涉及的模型种类繁多、类别不一。针对当前陆军作战仿真模型开发不规范、通用性与可重用性差、开发和集成效率低的现状,在对陆军作战仿真模型构成要素进行分析和归纳的基础上,提出仿真模型组件化设计的建模方法、采用"方案-单元-实体-组件"方式的模型管理机制以及采用事件驱动、事件订购和分发方式的模型交互机制。     

基于近似策略的联合优化方法

针对优化中收敛速度和优化解全局性的问题,提出了一种联合优化方法:构造原问题的近似模型,使用全局优化方法对近似函数进行优化,得到优化点作为初值,再使用局部优化方法对原问题进行优化.为了获得对原问题更好的近似,改进了径向基插值方法,以优化误差的方法来选择参数.利用临近空间机翼模型的优化对算法进行了测试,结果表明,优化参数的...
