基于改进空战威胁评估模型的权重计算方法比较

针对多无人机(UAV)任务网协同空战态势威胁评估问题,在现有基本模型基础上增加考虑气象环境对威胁评估要素的影响和无人机的自主可靠性系数两个实际因素,提出一种改进的超视距空战威胁评估模型;同时,应用串联电阻分压法、改进AHP法和熵权法分别计算融合模型中各威胁指标的权重系数;进而,在考虑己方战机对敌方战机综合威胁与优势的基础上,介绍了战机协同空战目标分配的基本方案。最后,应用上述3种权重计算方法进行空战威胁仿真计算,计算结果表明改进空战威胁评估模型可有效改善空战决策性能。     

基于双层规划的通信干扰兵力部署优化

投掷式通信干扰机是未来通信对抗装备发展的一种趋势,针对其压制无线战术通信的兵力部署优化问题,引入"通信干扰压制概率"和"通信干扰效益"两个指标,建立了基于双层规划的兵力部署优化模型,上层规划以整体通信干扰效益最大化为目标,下层为随机机会约束规划,以通信干扰压制概率满足一定置信水平为约束,以干扰机需求量最小化为目标。采用随机模拟、遗传算法和动态规划相结合的混合智能算法求解双层规划模型,并通过算例分析验证了模型的有效性。     

Reserve forces and the transformation of British military organisation: soldiers,citizens and society

In recent years, there has been a sharp growth in political and sociological interest in the British military. Set against the backdrop of the armed forces’ increasing presence in everyday life, alongside the organizations’ ongoing restructuring, the current paper focuses on the MoD’s problematic attempts to recruit 30,000 reservists by 2020; what has become known as the Future Reserves 2020 programme (FR2020). We argue that these changes are driven in part by the need to cut costs in defence. However, we also suggest that they are a reflection of the changing nature of modern military organisation, and the manner in which armed forces engage with the societies of which they are a part, and with the citizens that make up that society. We locate FR2020 programme in the context of a wider narrative about the changing nature of military organisation in contemporary western democracies, identifying structural, circumstantial and normative reasons for change. We also examine the specific challenges of implementing FR2020 in practice, including issues of recruitment and retention, integration and support, and relations with families and employers, drawing on the experience of comparator countries to do so. We conclude by considering the implications of these changes, both for the future of UK armed forces, and for the evolving nature of military-society relations in Britain.     

Constraining missile defence†

Assessing missile defence through the prism of offence–defence theory requires primarily an examination of legal and structural constraints on future development. New weapons technology is frequently cited as having the most critical impact on the offence–defence balance. Yet, the method for assessing the introduction of a new weapons technology tends to neglect projected maturity and instead focus excessively on the initial rudimentary capabilities. It is argued here that the North Atlantic Treaty Organisation’s (NATO’s) missile defence is set to incrementally become more advanced in terms of quality, quantity and mobility, which is supported by a strategy that is increasingly favouring offence. As the system gradually enhances the offensive advantage vis-à-vis Russia, NATO categorically rejects any legal or structural constraints on future deployments.     

带优先级的单类型航空弹药转运多目标规划模型

针对航母航空弹药转运过程非常复杂、涉及设备多、要求高的特点,在对其流程进行细致分析的基础上,将其抽象为一个两阶段多目标规划问题。同时,深入分析了转运过程中的各种约束条件、构建了该问题的两阶段优化模型。建模时,不仅考虑了武器升降机的有效利用、弹药量的合理分配等因素,还考虑了转运时对于不同类型弹药转运优先级与停机区弹药需求优先级的要求。通过模型优化,在满足转运优先级要求的基础上,能有效提高航空弹药的转运效率。

美军作战试验与鉴定发展研究

当前,军队装备试验鉴定正由性能试验向作战试验、在役考核全领域拓展。在装备试验鉴定体系全面重塑的历史背景下,为适应军队装备试验鉴定发展新变化,探索装备试验鉴定新理论,推进装备试验鉴定自主创新发展,亟需开展装备试验鉴定技术研究。美军相对较早开展了装备试验与鉴定工作,在作战试验与鉴定工作方面已形成了较完善的法规制度体系和规范的操作流程,有较成熟的理论与方法成果可供借鉴。与此同时,美军作战试验与鉴定工作也面临许多新问题。本文剖析了美军作战试验与鉴定的内涵和管理模式,研究了2018和2019年美军作战试验与鉴定的重点技术领域,并进行了对比分析,以期掌握近期美军作战试验与鉴定工作的发展变化。     

基于SWOT分析的我国海上方向空中安全形势及对策措施

海上方向是强敌对我实施战略围堵和遏制的主要方向。随着美国国防战略重回大国竞争,其遏制中国的手段推陈出新,尤其是在海空方向对我施压强度频度与日俱增。文章运用SWOT方法对我国海上方向空中安全形势进行了全面分析,认为优势体现在联合作战指挥体制、国防动员能力、列装新型防空武器等方面,劣势体现在战场建设滞后、预警探测拦截打击能力不足等方面,机遇体现在中美共识与相对稳定的周边环境,威胁体现在强敌对我的侦察威慑、空天打击、海空封锁。通过构建我国海上方向空中安全的SWOT分析矩阵,提出要进一步深化改革,加强军队与地方、平时与战时、作战力量和作战环节的“三个统筹”,发展新型防空、预警装备,以及加强沿海防空战场建设等。     

The practice of strategy: South African defence in stasis

The article concerns the strategy development processes of the South African Department of Defence in South Africa. It intends to identify the probable causes of the observed failure of the South African National Defence Force to develop appropriate departmental policy and military strategy. Military strategy comprises force development, force employment, force deployment and the coordination of these elements in pursuit of national, grand-strategic objectives. (See Dennis M. Drew and Donald M. Snow, Making Twenty-first Century Strategy: An Introduction to Modern National Security Processes and Problems Montgomery, AL: Air University Press, Maxwell Air Force Base, November 2006, 103). Of these four constructs, the article concerns itself only with the first two. The article analyses two complementary approaches to strategy formation: a resource-driven, inside-out model and an interests-driven, outside-in method. The article concludes that the Department is preoccupied with the inside-out method to the lasting detriment of the declared strategic intent of the defence policy.
