A sequential attribute sampling inspection game for item facilities

The routine inspection of facilities storing large numbers of identical items is modeled as a two‐person, sequential game. Timely detection of illegal activity is parameterized in terms of a critical time to detection, and equilibria are derived which provide inspection strategies. Necessary conditions for deterrence of illegal behavior are discussed. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 496–505, 2001

基础知识在《理论力学》课程中的地位和学习方法

很多学生没有学习好<理论力学>的主要原因是对基础知识重视不够、学习方法不科学.为此,在强调基础知识重要性的同时,结合典型的例子,着重对于基本概念、基本理论、基本技能等3个方面的学习方法,进行了分析和讨论.     

空间应急飞行器姿态快速机动控制研究

以空间应急飞行器姿态机动快速控制过程为研究对象,对姿态快速解耦控制问题进行研究.采用决策树理论对时间最优控制和倾斜开关曲线控制这两种控制策略进行综合,以控制时间作为代价函数,获得三通道时间最优控制策略.与其他方法相比,本控制策略控制时间大幅缩短,控制精度满足设计需求.另外对控制器不同控制周期下的控制效果进行仿真比较,对控制器控制周期选择具有指导意义.     

考虑仿真可信度的舰炮虚拟校射

为利用仿真模型在有限校射样本的条件下对校射补偿量进行合理估计,对考虑仿真可信度的舰炮虚拟校射方法进行了研究。对自适应加权贝叶斯估计方法进行了研究,一方面对仿真先验可信度的计算方法进行了分析,另一方面对考虑先验可信度的自适应加权贝叶斯估计算法进行了研究。在此基础上,结合舰炮虚拟校射的原理和需求,建立了舰炮虚拟校射诸元误差自适应加权贝叶斯估计模型。仿真验证表明:自适应加权贝叶斯估计方法能够利用试验数据对仿真模型的可信度进行有效验证并进一步实现对目标分布的有效估计;所设计的校射方法能够综合利用仿真模型和校射样本的优势,实现对诸元误差的合理估计,达到有效提高校射精度的目的。     

Hybrid warfare through the lens of strategic theory

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.     

It Takes Two to Tango: Autocratic underbalancing,regime legitimacy and China’s responses to India’s rise

What factors do autocracies evaluate when responding to perceived threats and why might they fail to balance appropriately? I posit that autocratic leaders may choose greater exposure to an external threat if, by doing so, it preserves regime legitimacy. Specifically, the desire to promote a positive image to one’s domestic public creates incentives to publicly downplay a rival’s military progress, which then affects the state’s ability to mobilize resources to respond to the growing threat. I test this theory in the case of China’s response to India’s military rise. This research contributes to balancing theory and empirical work on East Asian security.     

一种基于证据间距离和信息熵的证据组合方法?

针对改进的基于证据间距离的组合方法,首先计算证据间距离并求出各个证据的支持度和可信度,选取支持度高的作为较可信证据,其次引入证据信息熵,计算修正系数,对这些证据的可信度进行修正,将可信度作为权重,进行证据的加权平均,再利用Dempster组合规则对所有证据进行融合。算例表明,该方法比现有的方法更加有效。     

一种修正的冲突证据融合方法

对于冲突证据,D-S证据理论无法使用甚至无法得出正确的结果,进而引发了专家学者的研究。针对该问题,提出了一种新的冲突证据融合方法,建立了多传感器综合可信度的计算模型,根据综合可信度得到多传感器的合成结果,采用D-S证据理论对合成结果进行组合,既解决了高冲突问题,又解决了低冲突问题。最后通过仿真验证了该方法的有效性。
