“Smart Defense” is NATO's new approach to risk- and burden-sharing, which has been a chronic problem within the alliance since the 1950s. Numerous solutions have been proposed, but initiatives resulting in more equitable burden-sharing have never been fully implemented. There are two driving forces influencing a county's willingness to support such initiatives – the economic theory of alliances and the risks posed by the implementation of capability sharing. The authors examine each of these and propose that rather than aiming for group consensus on the production of capabilities, NATO should focus on interoperability through support functions. This approach provides the most likely solution for connecting the forces, doctrine, procedures, standards and other factors of joint capability production such that country leaders find the risks of doing so to be politically and militarily acceptable.  相似文献

This article investigates how US national security planners have envisioned the emerging strategic environment during the early twenty-first century and evaluates how their perceptions of this strategic environment have changed during these years. This conceptual evolution can be seen in how defense planners define threats, identify defense priorities, and design security strategies. Five key strategic planning documents serve as the basis for this analysis and illustrate significant shifts in how the US government has envisioned its own security requirements as well as the context within which its strategic vision will need to be realized. These planning documents are: (1) Joint Vision 2020, (2) the Bush Administration's 2002 National Security Strategy of the United States, (3) the Obama Administration's 2010 National Security Strategy, (4) US Strategic Defense Guidance entitled Sustaining US Global Leadership: Priorities for 21st Century Defense, and (5) the US Chairman of the Joint Chiefs of Staff's Capstone Concept for Joint Operations: Joint Force 2020.  相似文献

This paper analyzes defense spending preferences using ordered logit regression analysis of American National Election Survey data from 1980 through 2008. Our results indicate that as opposed to having the ideology of isolationism, political party identification towards the Republican Party or having economic stakes in defense spending always play a significant role in increased preference towards defense spending. Demographic groups such as Native Americans, Hispanics, and retired women, a demographic subgroup, display generally positive preferences towards defense spending. Somewhat surprisingly, another demographic subgroup, ‘security moms,’ do not show a preference. Our analysis also displays lower (higher) preference in the early 1990s (2000s) for defense spending compared to the year 2008.  相似文献

Motivated by the presence of loss‐averse decision making behavior in practice, this article considers a supply chain consisting of a firm and strategic consumers who possess an S‐shaped loss‐averse utility function. In the model, consumers decide the purchase timing and the firm chooses the inventory level. We find that the loss‐averse consumers' strategic purchasing behavior is determined by their perceived gain and loss from strategic purchase delay, and the given rationing risk. Thus, the firm that is cognizant of this property tailors its inventory stocking policy based on the consumers' loss‐averse behavior such as their perceived values of gain and loss, and their sensitivity to them. We also demonstrate that the firm's equilibrium inventory stocking policy reflects both the economic logic of the traditional newsvendor inventory model, and the loss‐averse behavior of consumers. The equilibrium order quantity is significantly different from those derived from models that assume that the consumers are risk neutral and homogeneous in their valuations. We show that the firm that ignores strategic consumer's loss‐aversion behavior tends to keep an unnecessarily high inventory level that leads to excessive leftovers. Our numerical experiments further reveal that in some extreme cases the firm that ignores strategic consumer's loss‐aversion behavior generates almost 92% more leftovers than the firm that possesses consumers’ loss‐aversion information and takes it into account when making managerial decisions. To mitigate the consumer's forward‐looking behavior, we propose the adoption of the practice of agile supply chain management, which possesses the following attributes: (i) procuring inventory after observing real‐time demand information, (ii) enhanced design (which maintains the current production mix but improves the product performance to a higher level), and (iii) customized design (which maintains the current performance level but increases the variety of the current production line to meet consumers’ specific demands). We show that such a practice can induce the consumer to make early purchases by increasing their rationing risk, increasing the product value, or diversifying the product line. © 2015 Wiley Periodicals, Inc.

一种用于SEAD任务的改进型Voronoi图   总被引:1,自引:0,他引:1       下载免费PDF全文
根据雷达所在位置构造Delaunay三角形,取它的外心作为Voronoi图的顶点,构造常规Voronoi图,使用随机搜索算法可以为无人战斗机规划安全路径。由于战场环境威胁各异,使用常规Voronoi图不再能表征真实的SEAD任务,增大了无人战斗机的威胁,本文提出了一种新的Voronoi图的改进方法,以提高无人战斗机在执行SEAD任务时的生存概率。首先,根据可能出现的各种情况进行了分析,提出了改进型Voronoi图的构图原则。然后,提出了在不同威胁体下,基于"Delaunay多边形"构造改进型Voronoi图的方法。最后,进行了仿真。仿真算例的结果验证此方法可以明显地提高无人战斗机的生存概率。  相似文献

在体系SoS(System-of-Systems)工程领域中,如何构建科学合理的装备体系结构,即装备体系决策一直是众多问题中的热点之一。执行视图EV(Executive Views)是美军在解决体系决策问题方面的最新研究成果。与以往的工程手段相比,执行视图具有便于理解、易于使用、适于高层决策的特点,它为解决庞大复杂的体系决策问题提供了强有力的支持。美国陆军已经率先将执行视图应用于其指挥控制(C2)体系的决策之中,并取得了良好的效果。描述了执行视图产生的背景,通过示例展现了执行视图的开发结果和信息表示方法,并对传统视图和执行视图进行了比较。  相似文献
