要地防空敌袭主攻方向判断方法研究

主要对要地防空时多个可能的敌空袭兵器来袭方向进行了分析,并确定每个来袭方向的综合评价指标。应用模糊层次分析法建立多层次的评价指标体系,确立被评事物对各等级模糊子集的隶属度。应用灰色关联理论消除各个因素之间的量纲和数量级差异,将综合运算得到的量值进行排序比较,以供指挥员进行战场情况判断。     

“Effing” the military: a political misunderstanding of management

The use of commercial business management techniques is widespread in all government departments, including the Ministry of Defence. This article examines the use of popular management techniques in the Armed Forces and argues that their application is misplaced. It looks at what the “effs” – “efficiency” and “effectiveness” – mean in the business world and to the Armed Forces. It compares the definitions both in business and the Armed Forces and finds that there are few, if any, situations where the same measurements can be applied. Whilst many management techniques are suited for business, the function of the Armed Forces and its output cannot be measured in the same way, complicated by the different metrics of “efficiency” in peace and in war. This difference may not be clearly understood by some politicians, or indeed by some senior military personnel. Using examples from some of the most popular management techniques such as “Lean” and “Agile” it is possible to see that their use might actually diminish the capabilities of the Armed Forces when it comes to performing their principal role – the use of force to achieve political objectives.

Effects of lethality in naval combat models

In the context of both discrete time salvo models and continuous time Lanchester models we examine the effect on naval combat of lethality: that is, the relative balance between the offensive and defensive attributes of the units involved. We define three distinct levels of lethality and describe the distinguishing features of combat for each level. We discuss the implications of these characteristics for naval decision‐makers; in particular, we show that the usefulness of the intuitive concept “more is better” varies greatly depending on the lethality level. © 2003 Wiley Periodicals, Inc.

计算机网络级联失效建模与分析

针对以往级联失效模型负载局部重分配规则与现实计算机网络全局路由特点不吻合的缺陷,模拟网络中信息流传输过程。定义路由器的失效条件,建立基于负载全局重分配的级联失效模型,并在此基础上提出基于连通和性能两方面的级联失效影响评价参数,进而分析用户流量和攻击方式对计算机网络级联失效的影响。结果表明,随着流量的增大,级联失效存在相变行为,相变点刻画了网络在不会发生级联失效前提下的最大传输能力。此外,针对网络中高度节点的攻击,更为容易引发大规模的级联失效,应予以重点保护。
