基于排队网络理论的适用性分析以及基本假设与适当简化,将防空群对多批次、小间隔目标射击问题转化、抽象为排队网络对顾客流的服务问题,建立了防空群对多批次、小间隔目标射击效能评估的"分布式协同排队网络"模型。在特定作战实例和假设条件下,应用所建模型,计算得出了典型火力配属方案下防空群对多批次、小间隔目标射击效能的量化结果,实现了防空群对多批次、小间隔目标的射击效能的定量化评估,验证了所建模型的可行性与有效性。  相似文献

The use of commercial business management techniques is widespread in all government departments, including the Ministry of Defence. This article examines the use of popular management techniques in the Armed Forces and argues that their application is misplaced. It looks at what the “effs” – “efficiency” and “effectiveness” – mean in the business world and to the Armed Forces. It compares the definitions both in business and the Armed Forces and finds that there are few, if any, situations where the same measurements can be applied. Whilst many management techniques are suited for business, the function of the Armed Forces and its output cannot be measured in the same way, complicated by the different metrics of “efficiency” in peace and in war. This difference may not be clearly understood by some politicians, or indeed by some senior military personnel. Using examples from some of the most popular management techniques such as “Lean” and “Agile” it is possible to see that their use might actually diminish the capabilities of the Armed Forces when it comes to performing their principal role – the use of force to achieve political objectives.  相似文献

This article aims to encourage the fostering of more systems thinking, and its greater exploitation, within the domain of contemporary intelligence. With particular focus on “micro systems thinking” and with reference to key intelligence processes, such as intelligence analysis, the utility of many systems dynamics within the intelligence context seeks to be further revealed. Through their greater collective harnessing, including up to “System of Systems” (“SoS”) dynamics, and promoting all that they can offer, more sophisticated overarching operational-to-strategic/policy “ends,” notably that of “defence-in-depth,” can be viably further advanced in a sustainable manner into the future. Arguably, a much-needed transformative impact on contemporary intelligence can also be increasingly realised through comprehensively engaging in and with more systems and SoS thinking. Aiding civil protection tasks, crisis management, emergency planners, and civil contingency practitioners likewise gain.  相似文献

Assessing missile defence through the prism of offence–defence theory requires primarily an examination of legal and structural constraints on future development. New weapons technology is frequently cited as having the most critical impact on the offence–defence balance. Yet, the method for assessing the introduction of a new weapons technology tends to neglect projected maturity and instead focus excessively on the initial rudimentary capabilities. It is argued here that the North Atlantic Treaty Organisation’s (NATO’s) missile defence is set to incrementally become more advanced in terms of quality, quantity and mobility, which is supported by a strategy that is increasingly favouring offence. As the system gradually enhances the offensive advantage vis-à-vis Russia, NATO categorically rejects any legal or structural constraints on future deployments.  相似文献

The article concerns the strategy development processes of the South African Department of Defence in South Africa. It intends to identify the probable causes of the observed failure of the South African National Defence Force to develop appropriate departmental policy and military strategy. Military strategy comprises force development, force employment, force deployment and the coordination of these elements in pursuit of national, grand-strategic objectives. (See Dennis M. Drew and Donald M. Snow, Making Twenty-first Century Strategy: An Introduction to Modern National Security Processes and Problems Montgomery, AL: Air University Press, Maxwell Air Force Base, November 2006, 103). Of these four constructs, the article concerns itself only with the first two. The article analyses two complementary approaches to strategy formation: a resource-driven, inside-out model and an interests-driven, outside-in method. The article concludes that the Department is preoccupied with the inside-out method to the lasting detriment of the declared strategic intent of the defence policy.  相似文献

三道防线是防空领域的重大军事变革   总被引:5,自引:3,他引:2  
当前国土防空和舰队防空中,面临的空袭特点是空袭体系从防区外和视线外对防空体系所保卫的地(水)面目标实施饱和攻击。为了对抗这样的空袭战术,防空体系必须从以投弹圈为唯一防线的作战模式中解放出来,向远程打击预警机,中程拦截空袭武器载机和近程防御空袭武器的三道防线转变。这一转变牵动了防空体系和防空导弹的发展方向,因此是防空领域的一次重大军事变革。  相似文献
