标准化工作在新型号产品研制或引进技术产品国产化中有不可忽视的重要作用,并已被实践所证明。《武器装备研制的标准化工作规定》、《新产品研制的标准化工作规定》中也都提出在新型产品研制项目中建立总设计师系统的同时,应建立相应的标准化工作系统。明确该系统如何建立,它的任务、职责以及工作程序是非常必要的。 相似文献

ABSTRACTGraham Farmelo's new book on the early British nuclear weapon program assembles a fascinating cast of characters in a gripping narrative. It particularly succeeds at illustrating the importance of “atomic energy” imagery in the United Kingdom well before the discovery of fission, and provides nuanced insights into Churchill's handling of issues relating to the atomic bomb and scientific expertise. However, in arguing that the British had a “lead” on the manufacture of atomic bombs that was “lost” to the United States during the early Manhattan Project, the book overstates its case, and in the process misunderstands what it took to make the bomb. 相似文献

Analysis of the failures of African security forces generally focuses on structural issues such as corruption of senior leadership, insufficient equipment and training, and coup d’état fears driving mistrust of armies that are too strong or effective. However, less examined is the role that sub-state identity plays; using Libya, South Sudan, and Mali as case studies, this paper examines how ethnicity inhibits the development of national armies, divides them, and exposes a critical flaw that adversaries are able to exploit. Given the increasingly ethnic nature of conflict throughout the world, and the rising threat that ethnic conflicts in Africa pose to regional and Western partners, it may be prudent for researchers, policymakers and other stakeholders to examine the critical role that sub-state identity plays in undermining African security forces. 相似文献

This paper considers the problem of allocating weapons to achieve targeting objectives while simultaneously minimizing aggregate damage to surrounding nonmilitary facilities, each of which has an upper limit to the damage it is permitted to incur. A model is formulated which assumes only that damage to individual targets or associated facilities does not decrease as the number of allocated weapons increases. An implicit enumeration algorithm, based on that of Lawler and Bell is described that yields optimal integer solutions. An example is presented. 相似文献

A single machine is available to process a collection of stochastic tasks. Processing is interrupted when the machine breaks down. We introduce a new model of breakdowns that more realistically incorporates the effects that job processing may have on the machine. This failure propagation model is equivalent to a Bayesian formulation in which learning about breakdown rates occurs as jobs evolve. Optimal scheduling policies are described in terms of Gittins indices and these indices are characterised in two special cases. For example, we obtain conditions which ensure that an optimal policy will only preempt a job's processing either at its completion or at a machine breakdown. We also bound the value lost by simplistic modelling which ignores the learning phenomenon. © 1996 John Wiley & Sons, Inc. 相似文献

针对移动对象当前及未来位置索引不能有效支持多用户并发访问的问题,提出了一种支持高效并发访问的移动对象索引CS2B-tree(Concurrent Space-filling curve enabled Cache Sensitive B+-tree)。该索引结合了Bx-tree和CSB+-tree的特点,因而能够支持对移动对象进行预测查询且具有缓存敏感特性。重点研究了一种针对CS2B-tree的两层锁并发访问机制,特别是设计了一种网格锁备忘录结构,使得索引能够支持多任务并发执行。基于并发访问机制,分别提出了CS2B-tree的并发更新算法及并发预测范围查询算法。实验表明,相对于Bx-tree,CS2B-tree的并发访问的吞吐量提高了15.1%,响应时间减少了14.9%。 相似文献

This article assesses the existing literature on logistics in war, concluding that there is no satisfactory conceptual definition of logistics. It proposes a concept of logistics derived from Clausewitz's theory of war to fill that void. This is presented as a derivation because Clausewitz's distinction between (1) the use of the fighting forces (tactics and strategy) and (2) all other activities in war that were required so that forces could be taken as a given. The latter, left unnamed by Clausewitz, corresponds to a concept of logistics that proves to be an analytical peer to Clausewitz's categories of politics, tactics and strategy. 相似文献
