Network routing for insurgency: An adversarial risk analysis framework

Problems in counterterrorism and corporate competition have prompted research that attempts to combine statistical risk analysis with game theory in ways that support practical decision making. This article applies these methods of adversarial risk analysis to the problem of selecting a route through a network in which an opponent chooses vertices for ambush. The motivating application is convoy routing across a road network when there may be improvised explosive devices and imperfect intelligence about their locations. © 2011 Wiley Periodicals, Inc.

Allocating capacity in parallel queues to improve their resilience to deliberate attack

We develop models that lend insight into how to design systems that enjoy economies of scale in their operating costs, when those systems will subsequently face disruptions from accidents, acts of nature, or an intentional attack from a well‐informed attacker. The systems are modeled as parallel M/M/1 queues, and the key question is how to allocate service capacity among the queues to make the system resilient to worst‐case disruptions. We formulate this problem as a three‐level sequential game of perfect information between a defender and a hypothetical attacker. The optimal allocation of service capacity to queues depends on the type of attack one is facing. We distinguish between deterministic incremental attacks, where some, but not all, of the capacity of each attacked queue is knocked out, and zero‐one random‐outcome (ZORO) attacks, where the outcome is random and either all capacity at an attacked queue is knocked out or none is. There are differences in the way one should design systems in the face of incremental or ZORO attacks. For incremental attacks it is best to concentrate capacity. For ZORO attacks the optimal allocation is more complex, typically, but not always, involving spreading the service capacity out somewhat among the servers. © 2011 Wiley Periodicals, Inc.

开展军事理论课程教学的思考

军事理论课程教学,在武警部队“合训”院校课程设置中所处的位置越来越重要。如何在由培养工程技术类干部向指挥类干部“学历教育合训”为主的转变过程中,提高军事理论课程讲授的效益和质量,关键在于军事理论课程教学方法的选择与应用。     

干扰方式选择方法的研究

为实现对雷达的有效干扰,应选择最佳干扰方式。将干扰效能分为干扰效果和干扰效率2个方面,并对这2方面进行了定量描述,提出了新的干扰效能评估算法,建立了雷达对抗策略矩阵,在此基础上运用对策论的相关原理,研究了干扰方式的选择问题,最后结合实例进行了检验。结果表明,该方法可以有效得出最佳干扰方式。

对公共领域结构转型批判的批判

哈贝马斯的《公共领域结构转型》自刊出至今引起广泛争议,包括欧洲的社会历史学家和非欧洲的社会历史学家都参与到讨论之中,安德列斯.盖斯特里希在总结各种争端的基础上,从五个方面对哈贝马斯的理论展开批判,并以卢曼的社会分化理论作为替代方案整合各种哈贝马斯理论中存在的困难,但是在解释公共领域时也存在深刻的问题,因此运在通信技术批判理论的框架对安德列斯.盖斯特里希的观点加以批判和建构是必要的。     

由哲学观念到文学内涵的衍化——论明清诗话对孟子“养气说”的接受

孟子的＂养气说＂虽然最初只是传达一种哲学观念,但是后世的文论家却不断发展孟子的这一学说,逐步赋予其文学性内涵。而这一趋势在明清诗话中发展到极致。明清诗论家不仅开始用＂气＂对林林总总的诗歌进行分类、品评,并且也把孟子＂养气＂的观点带入到明清诗话中,用于探讨不同诗作风格的形成根源。
