关于加强公安现役部队科研环境建设的思考

目前公安现役部队科研环境建设,还存在项目申请难度大、投资渠道单一化、团结协作攻关难、科技资源共享少、学术科研氛围淡等问题,对人才队伍建设造成一定影响。坚持“以人为本”,加强制度建设,解放思想,增加投入,活跃学术氛围,树立科研标兵,以进一步改善和优化公安现役部队科研环境。     

Optimal resource allocation and redistribution strategy in military conflicts with Lanchester square law attrition

We address the problem of optimal decision‐making in conflicts based on Lanchester square law attrition model where a defending force needs to be partitioned optimally, and allocated to two different attacking forces of differing strengths and capabilities. We consider a resource allocation scheme called the Time Zero Allocation with Redistribution (TZAR) strategy, where allocation is followed by redistribution of defending forces, on the occurrence of certain decisive events. Unlike previous work on Lanchester attrition model based tactical decision‐making, which propose time sequential tactics through an optimal control approach, the present article focuses on obtaining simpler resource allocation tactics based on a static optimization framework, and demonstrates that the results obtained are similar to those obtained by the more complex dynamic optimal control solution. Complete solution for this strategy is obtained for optimal partitioning of resources of the defending forces. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008

Route optimization for multiple searchers

We consider a discrete time‐and‐space route‐optimization problem across a finite time horizon in which multiple searchers seek to detect one or more probabilistically moving targets. This article formulates a novel convex mixed‐integer nonlinear program for this problem that generalizes earlier models to situations with multiple targets, searcher deconfliction, and target‐ and location‐dependent search effectiveness. We present two solution approaches, one based on the cutting‐plane method and the other on linearization. These approaches result in the first practical exact algorithms for solving this important problem, which arises broadly in military, rescue, law enforcement, and border patrol operations. The cutting‐plane approach solves many realistically sized problem instances in a few minutes, while existing branch‐and‐bound algorithms fail. A specialized cut improves solution time by 50[percnt] in difficult problem instances. The approach based on linearization, which is applicable in important special cases, may further reduce solution time with one or two orders of magnitude. The solution time for the cutting‐plane approach tends to remain constant as the number of searchers grows. In part, then, we overcome the difficulty that earlier solution methods have with many searchers. © 2010 Wiley Periodicals, Inc. Naval Research Logistics, 2010     

军用飞机改进改型研制费用的参数估算法

首先分析并建立了军用飞机改进改型研制的费用分解结构,阐明了与新研飞机在各分项费用上的差别。基于当量工程的概念提出了用减缩系数来估算改进改型研制的费用修正和各分项费用的减缩系数的估计方法,结合现有成熟的参数估算模型建立了相应的改进改型研制的费用估算模型。最后,以某型飞机的改型研制费用为例进行了实例分析,结果表明方法与模型具有较好的有效性和实用性。     

Economic Espionage

We explore the efficacy of counterespionage measures in the realm of Economic Espionage. Although it is possible that increasing counterespionage measures has the desired effect of increasing domestic research and development (R&D) and reducing espionage by foreign entities, it is also possible that these increased measures actually do just the opposite: domestic R&D suffers and foreign stealing increases. We identify the appropriate settings for increased counterespionage measures and provide some policy advice.     

Data-driven research in retail operations—A review

We review the operations research/management science literature on data-driven methods in retail operations. This line of work has grown rapidly in recent years, thanks to the availability of high-quality data, improvements in computing hardware, and parallel developments in machine learning methodologies. We survey state-of-the-art studies in three core aspects of retail operations—assortment optimization, order fulfillment, and inventory management. We then conclude the paper by pointing out some interesting future research possibilities for our community.     

美国“国家实验室”的属性辨识

美国国家实验室是美国国家创新的核心力量。常规英文搜索引擎通常检索不到"美国‘国家实验室’清单",目前国内已有文献大都将"联邦资助的研究与发展中心"等同于"国家实验室"。本文通过对"联邦资助的研究与发展中心"的深入比对分析,对美国"国家实验室"的类型进行了定量辨识,认为只有该国能源部"国家实验室"系列、国防部主管的Lincoln Laboratory、Aerospace Federally Funded Research and Development Center、National Defense Research Institute和美国国家航天局主管的Jet Propulsion Laboratory等与国内对"国家实验室"的共识基本一致。     

军事法律关系的性质研究

军事法律关系是由军事法律规范调整的以军事权利和军事义务为内容而形成的一种特殊社会关系,这种社会关系必然涉及到国家军事利益。军事法律关系的性质如何,关系到军事法和军事法学的整体定位,对于军事法学的理论研究和实践探索具有重要的工具性价值。
