Modeling and analysis of a mixed‐model assembly line with stochastic operation times

We consider a mixed‐model assembly line (MMAL) comprised a set of workstations and a conveyor. The workstations are arranged in a serial configuration. The conveyor moves at a constant speed along the workstations. Initial units belonging to different models are successively fed onto the conveyor, and they are moved by the conveyor to pass through the workstations to gradually generate final products. All assembling tasks are manually performed with operation times to be stochastic. An important performance measure of MMALs is overload times that refer to uncompleted operations for operators within their work zones. This paper establishes a method to analyze the expected overload times for MMALs with stochastic operation times. The operation processes of operators form discrete time nonhomogeneous Markov processes with continuous state spaces. For a given daily production schedule, the expected overload times involve in analyzing the Markov processes for finite horizon. Based on some important properties of the performance measure, we propose an efficient approach for calculating the expected overload times. Numerical computations show that the results are very satisfactory. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007

基于ADV212的探空火箭图像采集与压缩系统

针对探空火箭遥测带宽低、图像监控通路多、系统小型化等设计难点,本文提出了一种基于ADV212的图像采集与压缩系统设计方案。采用可以同时支持无损和高压缩比有损压缩的JPEG2000图像压缩标准,提出适用于箭上图像采集特点的通道切换和中断处理策略,并以“乒乓”操作的流水线作业方式实现多路图像通道数据吞吐,通过两个实时发送通道和一个缓存发送通道向火箭遥测链路发送图像数据。提出了一种具有动态帧频和压缩比的图像压缩方案,解决了探空火箭遥测带宽有限这一问题。本设计以Virtex-4系列FPGA作为系统控制核心,采用ADV7182和ADV212分别完成图像的采集和压缩,分别采用SRAM和SDRAM实现图像的实时传输和缓存传输。通过比较图像间的PSNR值,试验并分析了适用于CCD图像的压缩滤波器和小波变换级数,得到了较为满意的图像质量。设计较好地满足了本次空间环境垂直探测探空火箭的图像采集任务。

The Damoclean sword of offensive cyber: Policy uncertainty and collective insecurity

Cyberspace is a new domain of operation, with its own characteristics. Cyber weapons differ qualitatively from kinetic ones: They generate effects by non-kinetic means through information, technology, and networks. Their properties, opportunities, and constraints are comparable to the qualitative difference between conventional and nuclear weapons. New weapons and their target sets in a new domain raise a series of unresolved policy challenges at the domestic, bilateral, and international levels about deterrence, attribution, and response. They also introduce new risks: uncertainty about unintended consequences, expectations of efficacy, and uncertainty about both the target’s and the international community’s response. Cyber operations offer considerable benefits for states to achieve strategic objectives both covertly and overtly. However, without a strategic framework to contain and possibly deter their use, make state and non-state behavior more predictable in the absence of reciprocal norms, and limit their impact, an environment where states face persistent attacks that nonetheless fall below the threshold of armed conflict presents a policy dilemma that reinforces collective insecurity.     

Mirror,mirror on the wall,who is the most offensive of them all? – Explaining the offensive bias in military tactical thinking

This article explores why the offensive predominates military tactical thinking. With survey results showing an offensive bias among 60 per cent of senior Swedish officers and as many as 80 per cent in the case of the army, it is clear that this is not just a problem of the past but is equally relevant today. The article asks why there is a tendency to perceive and understand offensive tactics as the preferred choice and the way to conduct battle that should be encouraged and preferred. Drawing on existing research and the findings of a pilot study, ten propositions for why the offensive bias exists are tested using a mixed-method approach. Based on the findings, the article develops a model to understand why the offensive dominates military tactical thinking. It is found that the two key constitutive factors behind the offensive bias are military culture and education. These factors most directly and profoundly influence an officer’s identity, perceptions, and thinking. Military culture and education, in turn, work as a prism for four other factors: military history, the theory and principles of war, doctrine and TTPs, and psychological factors.

海警部队参与海上反恐作战的思考

随着各国加强对空中和陆地恐怖主义的防控,恐怖主义把视角转向海上。海上恐怖主义具有事件的突发性、手段的多样性、处置的复杂性等特点。边防海警部队参与海上反恐作战有利于取得海上反恐斗争的胜利,有利于掌握海上反恐主动权,有利于顺应国际海上反恐斗争的形势。针对海上恐怖主义的特点,边防海警部队应做到以下几点：一是平时反恐作战准备应具有超前性,二是参与海上反恐作战应体现实效性,三是参与海上反恐作战应把握全局性。
