基于订阅分发机制的军事信息系统知识库协同框架探讨

针对分布在不同军工领域的小型知识库无法发挥跨领域知识按需共享的问题,提出了一种基于订阅/分发机制的分布式知识库协同框架,描述了知识库协同框架的系统结构以及主要的功能组成,通过知识库实例分析说明,阐明了协同框架进行数据交换共享的运行机制。

Addressing the “headwinds” faced by the European arms industry

ABSTRACT

The European arms industry is challenged by several adverse “headwinds.” Fragmentation leads to costly duplications and, in conjunction with stagnating budgets and sharply increasing costs, prevents firms from exploiting economies of scale and learning. This is exacerbated by size differentials vis-a-vis the leading US arms manufacturers and competition from emerging producers. As some “headwinds” are self-enforcing, far-reaching industrial and policy responses are required to improve the industry's outlook. As exports may not indefinitely compensate for low domestic demand, there is an economic imperative for further cross-border collaboration and consolidation. Despite various EU policy initiatives, progresses regarding the European Defence Equipment Market and strengthening the European Defence Technological Industrial Base have been relatively slow. It remains to be seen whether the European Defence Fund will be the proclaimed “game-changer,” raising competitiveness of the European arms industry. At the same time, the UK's withdrawal from the EU adds uncertainties.     

机动式保障基地系统防护需求分析

当前，军队工程防护对象以地下工程和野战阵地为主，对于设施设备及军事活动以地表为主的机动式保障基地系统，其毁伤特点规律、防护威胁、评估方法及防护标准等尚无专门研究。本文介绍了机动式保障基地系统的基本概念、主要功能及构成要素，研究了近年来典型军事基地遇袭案例，采用案例分析与数据库研究相结合的方法，分析了机动式保障基地系统的主要威胁及其毁伤元和毁伤评估量，并提出机动式保障基地系统防护需求的构建原则和评估步骤。根据建立的原则和步骤，建立5级防护需求等级，以海外维和基地为例，分析了基地内各类保障装备的防护等级需求和防护等级设置的主要依据，为开展机动式保障基地系统防护体系研究打下基础。     

More military base closure? Considering the alternatives*

Despite multiple base closing rounds, the United States Department of Defense still has excess base capacity, and thus President Trump and high-level Defense Department officials are calling for more base closure through the Base Realignment and Closure (BRAC) process. However, another BRAC may not be the optimal solution, because simple base closure is not an efficient way to reduce surplus base capacity. Thus, Defense Department officials should consider other methods to reduce surplus capacity, including reduction in base size, leasing excess base property, or transferring it to another government agency for a variety of alternative uses. The surplus capacity issue also offers an opportunity to DOD to reassess base utilization, to update base requirements with current and future force structure. While BRAC focuses on American military bases, the process and alternatives also have international applications.
