Strategy,theory, and history: Operation Husky 1943

In his 1987 work Strategy: The Logic of War and Peace (Harvard University Press, Cambridge, MA, 1987), Edward Luttwak described strategy as a field of activity characterised not only by an innately complex relationship between designs, actions and outcomes, but so too by the frequent disparity between its theory and praxis. Similar observations on this subject have since been made by Richard K. Betts, Lawrence Freedman and Antulio Echevarria II. This article will use the Allied invasion of Sicily in July–August 1943 as a vehicle through which to test these theories against a signal event in the European theatre of the Second World War. It will illustrate how Operation Husky and its aftermath are a paradigm of the confusing and often illogical course of events associated with the process of formulating strategy and waging war. In so doing it demonstrates the benefits of using strategic theory to illuminate events and so move beyond the often insular focus of campaign histories, and simultaneously reinforces the importance of military history in informing a theoretical understanding of strategy.

The correlates of transatlantic burden sharing: revising the agenda for theoretical and policy analysis

While recent work has attempted to update the research agenda for transatiantic defense burden-sharing, there remain significant gaps between the public choice defense economics literature and the security studies literature. The presence of such a gap is unfortunate, because defense spending choices are likely shaped by factors identified by the public choice literature, as well as the strategic and cultural variables that the security studies literature tends to focus on, as well as domestic macroeconomic factors. The independent variables identified in recent qualitative literature are extremely useful analytically, and, fortunately, they have reasonable proxies in available quantitative data, which enables scholars to study them across large groups of countries and many years. This article builds upon such work to synthesize the most notable of the factors identified in the current literature, and offers some common analytical ground that will benefit both scholars and practitioners..

Supply licensing when the manufacturer strategically commits to invest in R&D

This article proposes a strategic reason for a proprietary component supplier to license her technology to a competitor or a manufacturer: her anticipation of the manufacturer's strategic commitment to invest in research and development (R&D). We address this phenomenon with a game theoretic model. Our results show that the manufacturer's full commitment to invest in R&D enables the supplier to license, sell a larger quantity through the supply chain, and charge lower prices. These results are robust to the type of demand uncertainty faced by the manufacturer within the class of increasing generalized failure rate distributions. © 2014 Wiley Periodicals, Inc.

基于二元决策图的多阶段任务系统可靠性分析

分析了多阶段任务系统(PMS)可靠性分析中传统二元决策图(BDD)建模方法的不足,提出了一种将多阶段任务失效事件分解为互不相容的阶段失效事件,然后分别建立可靠性BDD模型的新方法。通过该方法建立的PMS可靠性BDD模型不但可以计算总体任务失效概率,同时也能计算任务在各阶段发生失效的概率。最后,给出了一个算例,验证了该算法的有效性。     

The “motivated bias” dilemma in warfare and intelligence

The goal of this article is to challenge the assumption of rationality in the behavior of decision-making units involved in security, defense, intelligence and warfare and to consider the influence of “motivated bias” in such instances. A review of motivational literature within international politics and a discussion of literature applying “motivated biases” to warfare and strategic surprise will offer an alternative view of the primacy of rationality in such decisions.     

基于事件的系统可靠性参数仿真算法

介绍了可以用扩展可靠性框图表示的系统的可靠性参数的仿真算法。首先,对扩展可靠性框图进行了介绍,提出了利用树状结构来描述扩展可靠性框图的结构。其次,对基于扩展可靠性框图的系统行为进行了分析。然后,依据离散事件系统仿真思想,分别给出了计算可修系统可靠性参数的仿真算法与不可修系统可靠性参数的仿真算法。最后,给出了计算实例。该仿真算法不仅可以对状态独立系统进行可靠性参数计算,而且可以对具有冷储备关系以及冷储备嵌套关系的状态相关系统进行可靠性参数计算,具有很强的通用性与实用性。
