为了解决评估决策过程中不同类型指标难以综合处理等问题,提出一种新的评估决策方法。该方法以投影技术为基础,将实数指标、区间型指标和模糊型指标综合起来,形成评估矩阵,并根据指标优劣差异对其进行规范化处理;然后通过各方案在某个指标下的评估差异值的大小确定该指标的权重,由此得出各方案在正负理想点上的投影,实现待评方案综合排序。以网络质量综合评估决策为例,对其基本原理和实施步骤进行了分析。实验结果表明:该方法是有效的,为多种类型指标综合评估决策提供了一种新思路。  相似文献

针对装备使用过程中对具体保障方案评估研究少,传统自我评估方法存在主观偏好等问题,采用基于交叉效率的数据包络分析法(DEA),对某保障单位近10年来的装备保障方案进行了评估。分析并构建了装备保障方案评估指标体系,建立了基于DEA交叉效率的装备保障方案评估模型;通过Matlab编程计算得出各方案效率值,并进行有效性分析;根据投影原理对DEA无效方案提出改进方向;通过交叉效率模型计算得出效率评估矩阵,据此对方案进行优劣排序;对比分析了CCR模型和交叉效率模型评估结果。实际评估表明,该方法有效克服了传统DEA评估方法指标权重确立主观性强、不能对有效决策单元进一步排序的不足,从而使评估结果更客观、可信。  相似文献

The UK’s interrogation operations during the conflict in Iraq (2003–2008) are often portrayed by the media as involving significant amounts of mistreatment. This article demonstrates that these practices are not necessarily representative of the UK’s interrogation operations across this conflict. In doing so it contributes to the limited literature on the practice of interrogation and on the UK’s combat operations in Iraq. The UK’s interrogation capability, and therefore its intelligence-gathering capability, is shown to have rested primarily with the military’s Joint Forward Interrogation Team (JFIT). The JFIT suffered from limitations to the number, training and experience of its interrogators and interpreters. It is argued that maintaining a permanent, higher level of preparedness for interrogation by the British armed forces is desirable.  相似文献

ABSTRACT

While the study of organised violence is considered essential to understanding the history of the West, and accordingly imbued with various layers of meaning and remembrance, war is widely regarded as inimical to the modern nation in Africa and stable development more broadly. Using examples drawn from primarily from East Africa, this paper considers the ways in which warfare in the deeper (‘precolonial’) past has been framed and envisioned in recent decades, in particular by governments whose own roots lie in revolutionary armed struggle and who began life as guerrilla movements. While in some cases particular elements of the deeper past were indeed mobilised in pursuit of contemporary political goals, in many other scenarios histories of precolonial violence were beheld as problematic and unworthy of remembrance. This paper highlights the paradox and ambiguity which has attended the memory of key aspects of Africa’s deeper past.  相似文献

This article consists of selected translations from captured interviews and dairies of Al Qaida members. The time period covered is from mid-2001 to early 2002 and concerns their operations in Afghanistan. The material clearly conveys a range of emotion, from confident to despondent, as well as efforts to contest the US actions. The first several pages give the reader context and some possible “lessons learned,” but the story(ies) are best told by the Al Qaida members themselves. All names are pseudonyms.  相似文献

The prospect of terrorists deploying weapons of mass destruction (WMD) is often referred to as the foremost danger to American national security. This danger has become more realistic because of al-Qaeda's expanding global network and the expressed willingness to kill thousands of civilians. In the past four years, numerous media reports have documented the group's ongoing quest for WMD capabilities; many reports have detailed al-Qaeda members’ attempts to manufacture or obtain certain chemical, biological, radiological, and nuclear (CBRN) agents to use in WMD against targets in the West and the Middle East. Yet the question remains: Does al-Qaeda's current WMD capability match its actual intent? While most studies of the group have focused on its explicit desire for WMD, allegations of CBRN acquisition, and the killing potential of specific CBRN agents, few open-source studies have closely examined the evolution of al-Qaeda's consideration of WMD and, most notably, the merit of actual CBRN production instructions as depicted and disseminated in the group's own literature and manuals. The following report will examine the history of al-Qaeda's interest in CBRN agents, the evolution of the network's attitude toward these weapons, and the internal debate within the organization concerning acquisition and use of WMD. More so, the following research will assess the validity of actual CBRN production instructions and capabilities as displayed and disseminated in al-Qaeda's own literature and websites.  相似文献

Despite the lance’s status and the amount of attention the couched lance has received in historiography, study of its martial art has been neglected. The various lance types and techniques used by western European cavalry have only recently begun to receive scholarly attention. Additionally, Medieval European lance use has too often been studied in isolation, without an adequate understanding of the idiosyncratic and asymmetrical dynamics of mounted combat. Although the charge with the couched lance was a valid tactic, it was only one of many. Light and heavy lances were used in one hand or two to trip, block, unhorse, and wrestle. These techniques were governed by the harsh laws of distance, speed, impact, iron, and asymmetry. By utilizing the surviving Fechtbücher and several Peninsular and Near Eastern sources, a brief foray into the diverse techniques of lance use and their purposes has been attempted here.  相似文献

This article describes the Distributed Interaction Campaign Model (DICM), an exploratory campaign analysis tool and asset allocation decision‐aid for managing geographically distributed and swarming naval and air forces. The model is capable of fast operation, while accounting for uncertainty in an opponent's plan. It is intended for use by commanders and analysts who have limited time for model runs, or a finite budget. The model is purpose‐built for the Pentagon's Office of Net Assessment, and supports analysis of the following questions: What happens when swarms of geographically distributed naval and air forces engage each other and what are the key elements of the opponents’ force to attack? Are there changes to force structure that make a force more effective, and what impacts will disruptions in enemy command and control and wide‐area surveillance have? Which insights are to be gained by fast exploratory mathematical/computational campaign analysis to augment and replace expensive and time‐consuming simulations? An illustrative example of model use is described in a simple test scenario. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 562–576, 2016  相似文献

Firth’s were the first of the Sheffield steel makers to enter the field armaments. Their involvement with Colt has been outlined in an article in the journal of the Colt Collectors Association in America and their activities as steelmakers to the small-arms industries has been covered in a previous issue of this Journal. This article gives a brief overview of their involvement as manufacturers in the field of heavy armaments, being the first to make all-steel guns and their evolving role in the use of steel for ordnance, culminating in the displacement of wrought iron by the adoption of steel for ordnance manufacture by the Royal Gun Factory in the 1880s. It also highlights their development of stainless steel in this context.  相似文献

ABSTRACT

While many militaries have tried to capitalize on the potential of information operations in internal war, few have succeeded. I argue that military information campaigns fall short of expectations for two reasons. First, the theory of influence militaries generally embrace – communications as a non-lethal weapons system – is largely invalid. While treating information as a weapons system makes it easier to integrate it into the existing military planning system, this overstates the independent effects of communications on behavior and understates the importance of interactive effects of what commercial marketing theory refers to as the “marketing mix” – product, price, promotion, and placement. It would be more appropriate to treat military information operations as a form of marketing: a composite effort to induce a specific behavior in a target audience by applying a combination of material and ideational instruments. The marketing model suggests that the efficacy of information operations will depend not simply on the message and its delivery (promotion) but on the behavior the sender seeks to induce (the product), the costs of that behavior (the price), and the opportunities available for such behavior (the placement).  相似文献
