Applying a bootstrap approach for setting reorder points in military supply systems

This paper develops and applies a nonparametric bootstrap methodology for setting inventory reorder points and a simple inequality for identifying existing reorder points that are unreasonably high. We demonstrate that an empirically based bootstrap method is both feasible and calculable for large inventories by applying it to the 1st Marine Expeditionary Force General Account, an inventory consisting of $20–30 million of stock for 10–20,000 different types of items. Further, we show that the bootstrap methodology works significantly better than the existing methodology based on mean days of supply. In fact, we demonstrate performance equivalent to the existing system with a reduced inventory at one‐half to one‐third the cost; conversely, we demonstrate significant improvement in fill rates and other inventory performance measures for an inventory of the same cost. © 2000 John Wiley & Sons, Inc.

军用安全模型扩展及其应用

在分析基于格理论的信息流控制军用安全模型在实际应用中存在的不足的基础上,从安全类定义和信息流控制策略两个方面对原模型进行了理论扩展和安全性分析.扩展模型安全类在作为对象和主体时具有相同的表达方式,以及在保持原模型信息流关系情况下,允许同职权等级用户交流他们共知的信息,以及高职权等级用户访问低职权等级用户他们之间共知的信息.以数字文档安全管理系统为例对扩展模型应用进行了描述.实例表明扩展模型更适合实际系统对信息流控制的要求.     

多分辨率建模及其军事应用

多分辨率建模是分布交互仿真中极其关键的技术,建模目的是根据情况需要动态改变分辨率,提高模型或模拟的灵活性和伸缩性,有效解决模拟复杂性与资源有限性等矛盾.介绍了当前多分辨率建模的主要方法:聚合-解聚法、一体化层次法和视点选择法.每种方法有各自的优缺点.多分辨率建模的难点主要是基础理论、一致性问题和应用研究等问题.     

Java语言在军用软件中的应用及实现方法

简要地分析了军用软件的现状和需求、Java语言的体系结构和系统特性、Java语言实时性的实现方法等。实时军用软件对开发语言的实时性要求很高,但是标准规范的Java语言本身不满足实时性能,因此,要想把Java语言应用到实时军用软件中必须首先解决Java语言的实时性的问题。     

论我国地方国家机关的军事立法权

我国地方国家机关享有国防职权和立法权,有权就国防事务制定地方性军事法规和地方性军事规章。地方国家机关的军事立法权既有法律依据,也有存在的必要性。但地方军事立法的内容是有限的,不应涉及军事行动和军队管理事项。     

Arming China: Major powers’ arms transfers to the People’s Republic of China

The rise of China has been fuelled by a massive military modernisation programme relying, in large part, on the acquisition of foreign military equipment. The question of how the world’s major powers define their arms transfer policies towards China is therefore crucially important. This article makes two original contributions. First, drawing on neoclassical realism, it proposes an explanatory framework integrating international and domestic factors to explain variations in major powers’ arms transfers. Second, based on a large body of elite interviews and diplomatic cables, it offers the first comprehensive comparison of American, British, French and Russian arms transfer policies towards China since the end of the Cold War.     

Think again – supplying war: reappraising military logistics and its centrality to strategy and war

This article argues that logistics constrains strategic opportunity while itself being heavily circumscribed by strategic and operational planning. With the academic literature all but ignoring the centrality of logistics to strategy and war, this article argues for a reappraisal of the critical role of military logistics, and posits that the study and conduct of war and strategy are incomplete at best or false at worst when they ignore this crucial component of the art of war. The article conceptualises the logistics–strategy nexus in a novel way, explores its contemporary manifestation in an age of uncertainty, and applies it to a detailed case study of UK operations in Iraq and Afghanistan since 2001.
