分布式网络化作战是网络中心战的基础,而分布式作战网络的构建是网络化作战的重要前提。首先,运用复杂网络的相关参数分析了多种不同的网络,选择了BA非标度网络作为分布式作战网络的最优表现形式;其次,以BA非标度网络为基础提出了一个适合军事上动态鲁棒性分析的模型DCNCE;最后,仿真结果表明,在以网络效能值为测度的对比下,分布式作战网络在介数毁伤策略下更脆弱,为构建并改进现有的作战网络提供了理论依据。     

一种基于0-1整数规划的全局数据分布优化方法

数据分布是影响并行程序在分布主存多处理机上执行性能的重要因素.针对分布主存多处理机中的数据分布问题,提出了一种基于0-1整数规划、利用数据变换技术进行有效数据分布的方法.该方法通过数据变换技术改变数据的存储布局,以使得数据能被有效地分布,并且该方法还利用数据分布图描述程序被并行的情况及其所含数组被访问的情况,并将全局数据分布优化问题转换为求解数据分布图中最优路径的问题,从而可用0-1整数规划求解最优路径问题.该方法能对多个嵌套循环中具有仿射数组下标的任意维数组进行有效的数据分布,并且也能使嵌套循环的并行度尽可能地大.另外,该方法也考虑了偏移常量的对准问题,从而能使数据通信量尽量地小.实验结果验证了该方法的有效性.     

An evolving state of play? Exploring competitive advantages of state assets in proliferation networks

Illicit procurement networks often target industry in developed economies to acquire materials and components of use in WMD and military programs. These procurement networks are ultimately directed by elements of the proliferating state and utilize state resources to undertake their activities: diplomats and missions, state intelligence networks, and state-connected logistical assets. These state assets have also been utilized to facilitate the export of WMD and military technologies in breach of sanctions. While used in most historic proliferation cases, their role has seen limited consideration in the scholarly literature. This article seeks to systematically contextualize state resources in proliferation networks, arguing that their use lies between state criminality and routine activity in support of national security. Considering the competitive advantages of these assets compared to similar resources available in the private sector, the article argues that nonproliferation efforts have caused states to change how they use these resources through an ongoing process of competitive adaptation.     

On the roles of free play in army exercises and the Russians

The article outlines the essential role of free play elements in various types of exercises for the development of in-depth and practical military professionalism. It thereafter argues why such use of free play contradicts the military science founded Russian Way of War.     

The building evacuation problem with shared information

In this article, the Building Evacuation Problem with Shared Information (BEPSI) is formulated as a mixed integer linear program, where the objective is to determine the set of routes along which to send evacuees (supply) from multiple locations throughout a building (sources) to the exits (sinks) such that the total time until all evacuees reach the exits is minimized. The formulation explicitly incorporates the constraints of shared information in providing online instructions to evacuees, ensuring that evacuees departing from an intermediate or source location at a mutual point in time receive common instructions. Arc travel time and capacity, as well as supply at the nodes, are permitted to vary with time and capacity is assumed to be recaptured over time. The BEPSI is shown to be NP‐hard. An exact technique based on Benders decomposition is proposed for its solution. Computational results from numerical experiments on a real‐world network representing a four‐story building are given. Results of experiments employing Benders cuts generated in solving a given problem instance as initial cuts in addressing an updated problem instance are also provided. © 2008 Wiley Periodicals, Inc.
