Survey and technological analysis of laser and its defense applications

The laser technology has made remarkable progress over the past couple of decades.It is being widely employed in diverse domains,such as holography,space sciences,spectroscopy,medical sciences,micro and power electronics,industrial engineering,and most distinctively,as directed energy military weapons.Owing to their active transmissions,laser systems are similar to microwave radars to some extent;however,unlike conventional radars,the laser operates at very high frequencies thus making it a potent enabler of narrow-beam and high energy aerial deployments,both in offensive and defensive roles.In modern avionics systems,laser target indicators and beam riders are the most common devices that are used to direct the Laser Guided Weapons(LGW)accurately to the ground targets.Additionally,compact size and outstanding angular resolution of laser-based systems motivate their use for drones and unmanned aerial applications.Moreover,the narrow-beam divergence of laser emissions offers a low probability of intercept,making it a suitable contender for secure transmissions and safety-critical operations.Furthermore,the developments in space sciences and laser technology have given syner-gistic potential outcomes to use laser systems in space operations.This paper comprehensively reviews laser applications and projects for strategic defense actions on the ground or in space.Additionally,a detailed analysis has been done on recent advancements of the laser technology for target indicators and range-finders.It also reviews the advancements in the field of laser communications for surveillance,its earlier state of the art,and ongoing scientific research and ad-vancements in the domain of high energy directed laser weapons that have revolutionized the evolving military battlefield.Besides offering a comprehensive taxonomy,the paper also critically analyzes some of the recent contributions in the associated domains.     

要地防空群对敌主攻方向确定度分析

针对目前防空作战中对敌主攻方向判断的困难和复杂性,运用系统工程理论、模糊数学等理论探索要地防空群对敌主攻方向定量判断问题。全面分析了影响敌主攻方向选取的诸多因素,建立了分析指标体系和模糊综合分析模型,为判断敌主攻方向提供了一种新的思路和定量分析的方法。在影响敌空袭目标选取的因素中,不确定和灰色的因素多,模糊综合分析方法采取定量与定性分析相结合的办法,把定性的因素定量化,较科学地解决了要地防空群对敌主攻方向判断的问题,进一步丰富了防空兵作战指挥精确决策理论。     

International armaments collaboration and the limits of reform

Budgetary pressures have driven a steady expansion of armaments collaboration projects internationally. This has also been the case in Europe where it is estimated that currently one-fifth of European procurement budgets are spent on collaborative weapons systems and the European Defence Agency has the long-term objective of increasing this figure by over 50%. The purpose of this article is to assess whether collaborative armaments projects can offer the benefits frequently attributed to them. To this end, the study examines the five combat aircraft projects that European states have collaboratively undertaken since the 1950s.     

基于系统动力学的工程项目目标控制

针对工程项目目标控制问题,通过德尔菲法确定工程项目目标控制的主要影响因素,基于系统动力学反馈与仿真分析理论建立了工程项目目标控制系统动力学模型。采用专家打分法确定参数,利用Vensim软件对模型进行模拟演化和算例分析,讨论不同策略和策略组合的工程项目目标控制效果,最终得到基于算例工程的理想方案为0时增加人工8人,0时加班1 d,管理费水平为3。采用该方案,该工程的完工时间提前47.2%,质量下降2.0%,费用上升6.7%。通过不同策略和策略组合的效果比较,得出结论：加班宜尽量少用,尤其要避免连续加班;尽量避免无效管理费用支出,但对于可以带来管理水平提高的管理费用支出宜适量增加;增加人工越早越好。
