基于反正切函数的测试性分配方法

针对现有主流测试性分配方法存在的分配指标过低和过高等不合理问题,分析认为其根源在于现有方法采用线性分配函数,而该函数不符合测试性指标提升规律,为此,构造了一种基于反正切函数的测试性分配函数,设计故障检测率与故障隔离率指标的分配算法,开展案例应用并与经典故障率分配法和综合加权分配法进行对比分析,结果表明随着分配权重(故障率)的变大,本方法分配指标的增幅逐渐减小,不会出现极低指标和超1指标的不合理情形。     

Dynamic routing of prioritized warranty repairs

Recent years have seen a strong trend toward outsourcing warranty repair services to outside vendors. In this article we consider the problem of dynamically routing warranty repairs to service vendors when warranties have priority levels. Each time an item under warranty fails, it is sent to one of the vendors for repair. Items covered by higher priority warranty receive higher priority in repair service. The manufacturer pays a fixed fee per repair and incurs a linear holding cost while an item is undergoing or waiting for repair. The objective is to minimize the manufacturer's long‐run average cost. Because of the complexity of the problem, it is very unlikely that there exist tractable ways to find the optimal routing strategies. Therefore, we propose five heuristic routing procedures that are applicable to real‐life problems. We evaluate the heuristics using simulation. The simulation results show that the index‐based “generalized join the shortest queue” policy, which applies a single policy improvement step to an initial state‐independent policy, performs the best among all five heuristics. © 2007 Wiley Periodicals, Inc.

二进制偏移载波调制信号畸变误差评估指标研究

随着全球卫星导航系统的发展,二进制偏移载波（BOC）调制信号被广泛采用。全面评估BOC信号的畸变误差对于导航系统的信号完好性评估与监测具有重要意义。前文对于BOC信号的畸变研究较少,没有解析评估BOC信号畸变误差的指标与方法。本文针对三种常见的信号畸变,给出了完善的畸变误差评估指标,能够全面评估畸变误差。同时采用提出的评估指标对北斗全球系统B1频段上的基线信号BOC(14,2)及MBOC(6,1,1/11)信号进行评估。文中提出的畸变误差评估指标能够用于评估现代卫星导航信号的畸变误差,对现代导航信号体制设计及完好性监测均具有指导意义。

Quantitative monitoring of military transformation in the period 1992–2010: Do the protagonists of transformation really change more than other countries?

Military transformation is a complex, slow, asymmetric, changeable, political, and not necessarily completely rational process that clearly needs an effective monitoring mechanism. This paper fills a gap in current literature by creating and testing a model for multi-dimensional and multi-level quantitative monitoring of military transformation applicable in any country. The model is based on 10 transformation indicators that reflect changes in organizational structure, personnel structure, weapon systems, and defense spending. Its application on a sample of seven countries (USA, United Kingdom, France, Netherlands, Poland, Russia, and China) in the period from 1992 to 2010 unexpectedly shows that the USA – a protagonist in the transformation process among allies as well as globally – has carried out the smallest relative change. The non-directed transformation index indicates that Russia carried out 51.8% more change (or 34.1 index units), and the directed index indicates that Poland carried out 157.2% (or 40.8 index units) more change than the USA.
