边防战术思维训练方法研究

边防战术思维是一个边缘性概念,它是选择并形成战斗方法的前提,也是当前边防战术训练的一个重要内容。因此．边防战术思维训练方法是当前边防实战指挥员、教练员或实战教员迫切需要提高的基本素质与基本能力。分析了边防战术思维训练的特点,从战例分析法、实战模拟训练法、模拟推演法等方面论述了边防战术思维训练的方法。     

基于数据链的航空作战进程研究

研究了数据链支持下的航空作战兵力变化问题。将空战能力指数通过映射关系转化为平均战斗力水平,从数学理论上证明了二者具有等价性。结合平均战斗力水平,建立了基于数据链的改进蓝彻斯特空战模型及具有增援力量的作战模型。仿真分析了等效实力比、不同初始值以及增援时刻的不同对空战进程的影响,结果表明数据链具有提高作战效能和改变战局的作用。实验发现了在增援作战时,存在"局部最优增援时刻点"这一重要结论。

Some comparisons of residual life of coherent systems with exchangeable components

Most of the research, on the study of the reliability properties of technical systems, assume that the components of the system operate independently. However, in real life situation, it is more reasonable to assume that there is dependency among the components of the system. In this article, we give sufficient conditions based on the signature and the joint distribution of component lifetimes to obtain stochastic ordering results for coherent and mixed systems with exchangeable components. Some stochastic orders on dynamic (or conditional) signature of coherent systems are also provided. © 2014 Wiley Periodicals, Inc. Naval Research Logistics 61: 549–556, 2014     

Effects of lethality in naval combat models

In the context of both discrete time salvo models and continuous time Lanchester models we examine the effect on naval combat of lethality: that is, the relative balance between the offensive and defensive attributes of the units involved. We define three distinct levels of lethality and describe the distinguishing features of combat for each level. We discuss the implications of these characteristics for naval decision‐makers; in particular, we show that the usefulness of the intuitive concept “more is better” varies greatly depending on the lethality level. © 2003 Wiley Periodicals, Inc.

Stochastic scheduling subject to machine breakdowns: The preemptive‐repeat model with discounted reward and other criteria

We consider the problem of scheduling a set of jobs on a single machine subject to random breakdowns. We focus on the preemptive‐repeat model, which addresses the situation where, if a machine breaks down during the processing of a job, the work done on the job prior to the breakdown is lost and the job will have to be started from the beginning again when the machine resumes its work. We allow that (i) the uptimes and downtimes of the machine follow general probability distributions, (ii) the breakdown process of the machine depends upon the job being processed, (iii) the processing times of the jobs are random variables following arbitrary distributions, and (iv) after a breakdown, the processing time of a job may either remain a same but unknown amount, or be resampled according to its probability distribution. We first derive the optimal policy for a class of problems under the criterion to maximize the expected discounted reward earned from completing all jobs. The result is then applied to further obtain the optimal policies for other due date‐related criteria. We also discuss a method to compute the moments and probability distributions of job completion times by using their Laplace transforms, which can convert a general stochastic scheduling problem to its deterministic equivalent. The weighted squared flowtime problem and the maintenance checkup and repair problem are analyzed as applications. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2004     

浅析《孙子兵法》中的战机思想

《孙子兵法》中蕴含着丰富而深刻的战机思想。不战全胜的“胜机”思想、立足不败的“待机”思想、变中求胜的“创机”思想、兵贵神速的“夺机”思想和因情用势的“握机”思想等内容,是《孙子兵法》战机思想的核心与精华。     

中国传统战争哲学理念的近代嬗变

近代以来,在西方列强坚船利炮的重创之下,中华民族在军事上接连失败。在严酷的现实面前,中华民族流传两千多年的传统战争哲学理念,受到了前所未有的挑战。在近代战争的冲击下,中国传统战争哲学理念开始了缓慢的嬗变历程。主要表现为三点：“避战求和”理念的破产与激变;“义战必胜”理念的质疑与超越;“道器合一”理念的背离与回归。
