Industrial supply chains have emerged as the focus of much economic and business research over the previous decade and defence is no exception. This paper reviews contributions made to the body of knowledge in this field with particular attention given to primary research undertaken on the UK defence industrial supply system. In doing so, the author assesses the quantity and quality of knowledge available to researchers, analysts and policy makers. There have been a number of valuable contributions to the literature and this paper reveals a subject that is extremely complicated, dynamic and yet under‐researched. It is suggested that it may well be this complexity and dynamism, coupled with difficulty in accessing data, that has inhibited research development in this field. Defence industry supply systems are repeatedly referred to as ‘chains’; however, primary research consistently suggests this is a misnomer – the author concludes that future analysis of the UK defence sector must embrace directly the economics of networks if understanding of the same is to progress and industrial ‘invisibility’ is to be avoided. 相似文献

Greece has regularly ranked as the country with the highest defence burden in NATO and the European Union. Over the past decades she has allocated an averatge 6% of GDP to defence yearly. This study using neural networks examines the external security determinants of Greek military expenditure in the context of the ongoing Greek‐Turkish conflict. 相似文献

防空监视网络传感器任务优先级的模糊评价方法 总被引:1,自引:1,他引:0
传感器任务优先级是传感器管理的重要依据。应用模糊推理技术的传感器任务优先级评价方法,基于所有融合航迹和识别数据,通过符号推理确定决策循环过程中执行的每个监视任务的优先级。首先确定了管理系统结构,建立了优先级决策树,给出了模糊推理规则,最后进行了仿真试验。试验结果说明了模糊评价方法在传感器管理应用中的有效性。 相似文献
