军用飞机改进改型研制费用的参数估算法

首先分析并建立了军用飞机改进改型研制的费用分解结构,阐明了与新研飞机在各分项费用上的差别。基于当量工程的概念提出了用减缩系数来估算改进改型研制的费用修正和各分项费用的减缩系数的估计方法,结合现有成熟的参数估算模型建立了相应的改进改型研制的费用估算模型。最后,以某型飞机的改型研制费用为例进行了实例分析,结果表明方法与模型具有较好的有效性和实用性。     

基于动态窗口的灰色加权填充算法及应用?

为解决复杂系统中单属性缺失数据填充困难问题,提出了基于动态窗口的灰色加权填充算法。该算法通过建立双向灰色预测模型,并采用模型精度评价系数加权填充缺失数据,有效增强了算法的准确性;提出基于灰色模型评价系数反馈的动态伸缩窗口概念,寻找产生最优模型的训练数据序列,使算法具有良好的鲁棒性和适应性。实验结果表明,该方法在RMSE和MA两项指标上均优于传统的双向灰插值、灰插值、多项式插值等方法。     

Brothers in arms,yet again? Twenty-first century Sino-Russian strategic collaboration in the realm of defence and security

2014–2015 were years of turmoil for strategic relations, with Sino-Russian relations emerging as a particularly interesting set of ties to observe. This article asks whether recurrent Sino-Russian exhortations of friendship are mirrored by their strategic alignment in the defence and security realm, half a century after the end of the Sino-Soviet pact during the communist era. We examine the arms trade between the two countries and with regional partners, but also the recent pattern of bilateral and multilateral military exercises, as a combined test of the security and defence relationship. We are able to show that the image of friendship that both Moscow and Beijing like to promote, while apparent at the UN Security Council and within the BRICS group, remains constrained by rivalry in high-tech segments of the arms industry and by lingering concerns about the prospects of peer interference in their shared regional vicinity.

STRATEGIC DEFENSE AND ATTACK FOR SERIES AND PARALLEL RELIABILITY SYSTEMS: COMMENT

The contest-theoretic literature on the attack and defense of networks of targets focuses primarily on pure-strategy Nash equilibria. Hausken's 2008 European Journal of Operational Research article typifies this approach, and many of the models in this literature either build upon this model or utilize similar techniques. We show that Hausken's characterization of Nash equilibrium is invalid for much of the parameter space examined and provides necessary conditions for his solution to hold. The complete characterization of mixed-strategy equilibria remains an open problem, although there exist solutions in the literature for special prominent cases.     

An informal framework to aid the analysis and design of military posture

The design of military posture is an exercise in confronting potential enemies’ capabilities within the context of geographic, technological, temporal, political and economic constraints. No formal model is capable of encapsulating the essentials of so complex an environment for closed or simulated analysis, but it is useful to have an informal framework within which to reason interactively within these dimensions.

This paper presents such a scaffolding, patterned on the notion of a military posture as the output of an economic process whose structure reflects important determinants of the characteristics and extents of weaponry and expenditures that are appropriate to the environment within the feasibility set determined by the constraints. The analysis remains at an abstract level, but it does highlight the important shifts toward preparation for littoral warfare, greater reliance on reserve rather than active forces, and necessary changes in missions among military departments.

培养军校学员战斗精神的几点思考

战斗精神是军事人才必备的素质,军队院校要把培养学员战斗精神作为自己的神圣职责。军校学员战斗精神的培养主要应从以下几个方面着手,即：把政治理论教育作为培养学员战斗精神的基础环节,把军事训练作为培养学员战斗精神的主要渠道,把严格的日常管理作为促进学员战斗精神生成的主要手段;营造良好的校园环境激发学员的战斗精神。
