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.     

Operational idealism: doctrine development of the Chinese People’s Liberation Army under Soviet threat, 1969–1989

This article analyses the doctrine development of the People’s Liberation Army (PLA) coping with the Soviet military threat between 1969 and 1989. In the 1970s, the PLA applied a doctrine of ‘active defence and luring the enemy into depth’ based on its traditional operational art. In 1980, the PLA decided to focus its doctrine on positional defence. In 1986, the PLA introduced ‘integrated operations and prioritised strike’, a generalised doctrine that originated from its war history. Many organisational and intellectual challenges in peacetime doctrine development contributed to the PLA’s operational idealism, including its aging leadership, command structure, attitude towards its previous experience, limited analysis of contemporary military developments, and failure in test and validation of doctrines. In the post-Cold War decade, many of these challenges persisted in spite of military modernization efforts. The ongoing military reform has to address these challenges and improve the PLA doctrine development in peacetime.     

基于三方动态博弈模型的网络生存防御策略优化配置

针对网络攻防环境中防御方以提高系统生存能力为目的所进行的最优生存防御策略的选取问题,提出了一种基于完全信息动态博弈理论的生存防御策略优化配置算法。将恶意攻击方、故障意外事件及防御方作为博弈的参与人,提出了一种混合战略模式下的三方动态博弈模型,对博弈的主要信息要素进行了说明,以混合战略纳什均衡理论为基础,将原纳什均衡条件式的表达式转化为可计算数值结果的表达式,并据此增加了近似的概念,最后,将提出的模型和近似纳什均衡求解算法应用到一个网络实例中,结果证明了模型和算法的可行性和有效性。

为解决LAMBDA算法搜索策略效率不高的问题,提出了一种基于部分搜索的模糊度解算新方法。该方法的解算成功率接近LAMBDA算法,且只需对最后3维模糊度元素采取搜索策略。同时,通过合理设定搜索椭球的大小和搜索策略;大大提高了搜索效率。通过实验对该新算法与Bootraping算法、LAMBDA算法进行了比较分析,进一步验证了该新算法的有效性。     

2014nccet：闪存阵列的可重构策略

利用低延迟、低功耗、高可靠的NAND Flash构建闪存存储阵列是实现高性能存储系统的有效手段。但应用传统RAID技术构建闪存存储阵列,会引入磨损均衡,校验数据更新频繁导致阵列生命周期降低等问题。针对闪存固有的读写特性,设计实现了一种基于NAND Flash的高性能RAID机制——基于缓存的可重构RAID策略（Cache-Based Reconfigurable RAID,CBR-RAID）。该机制采用可重构条带的思想,利用非易失存储器SCM（Storage Class Memory）作为缓存,对数据顺序重组。实验结果表明该策略能够有效降低垃圾回收开销,提高闪存阵列的性能和使用寿命
