一种电路模块故障诊断的实现方法

在分析电路模块故障诊断特性的基础上,本文利用表结构表示推理规则,以框架结构组织规则库,为快速孤立故障,将症状按其检测的难易程度划分类别,并由检测点的选择准则确定下一个能有效孤立故障的检测点,该方法在“电子装备模块级故障诊断系统”和某装备测距系统与搜索系统的实际故障处理中得到了应用,并证实了其有效性。     

自动武器可靠性寿命分布规律研究

本文对两种具有代表性的自动武器收集其生产验收寿命试验的故障记录,经处理得出寿命子样,再用皮尔逊检验进行分布函数检验,从中发现自动武器寿命分布服从指数分布,为研究自动武器可靠性指标及其验收方法提供了理论依据。     

提高聚氨酯推进剂基体粘结强度的途径探索

聚氨酯的水解稳定性较差,粘结强度偏低。将端羟基聚丁二烯与聚氨酯进行共混改性,提高了聚氨酯基体的表观交联度及推进剂的拉伸强度。采用示差扫描量热法和红外光谱法分析基体共混物的微观结构,表明这是提高聚氨酯基体粘结强度的一条有效途径。     

国家安全视角下的网络文化安全形势与对策

互联网的发展加速了权力分散,对我国的国家安全尤其是文化安全维护提出了新的问题。当前,我国社会进入新时代发展阶段,社会主要矛盾发生重要变化。与互联网尤其是网络文化安全有关的风险和挑战不断增多,互联网已经成为文化安全斗争的主战场。如何直面挑战,着力维护网络文化安全,提出队伍建设、舆论阵地和平台建设、维护手段、思维和素养、机制和法规建设的对策方法。     

信息化条件下基于大数据的后装一体化保障构想

由于契约的不完全性、专用性资产的存在,导致民企参军的谈判过程中,一方可能利用另一方因专用性资产投资的锁定效应,而采取机会主义行为将另一方套牢,攫取可占用专用性准租金。这种套牢风险不是单向的,而是双向的,双向套牢风险的存在不仅会降低军品科研生产项目建设质量,而且还会严重挫伤民营企业承担军品科研生产任务的积极性。为有效防范双向套牢风险,本文将从博弈论的角度,建立民营企业与军队采办部门的期望收益与专用性资产投资的函数关系和博弈矩阵,分阶段讨论民营企业与军队采办部门所面临的套牢风险大小及各自的最佳行为选择。以降低民企参军面临的套牢风险,引导更多优势民营企业进入军品科研生产与维修领域,推动军民融合的深度发展。

信息化战争环境对军人认知过程的影响和对策

信息化战争的激烈和紧张程度使参战军人承受超负荷的心理压力。声势浩大的心理攻势进一步拓展了信息化战争中参战军人的认知空间。要研究信息化战争对军人认知过程和认知能力的影响,引导我军官兵正确认识信息化战争环境,有针对性地加强心理训练,提高认知能力,在未来信息化战争中从容应对挑战。     

基于SQP法的助推-滑翔导弹助推段弹道优化研究

轨迹优化是飞行器总体优化设计中的重要组成部分,它贯穿于飞行器的整个设计过程。高超声速助推-滑翔导弹的弹道优化问题涉及攻角、法向过载、最大动压等多种约束条件,是一种复杂的最优控制问题。序列二次规划法（SQP）是解决该类问题行之有效的数值优化方法。本文利用SQP算法对助推-滑翔导弹助推段进行弹道优化,为这一高超声速飞行器的整体结构设计提供了有益的参考。     

Value management of diagnostic equipment with cancelation,no‐show,and emergency patients

Magnetic resonance imaging and other multifunctional diagnostic facilities, which are considered as scarce resources of hospitals, typically provide services to patients with different medical needs. This article examines the admission policies during the appointment management of such facilities. We consider two categories of patients: regular patients who are scheduled in advance through an appointment system and emergency patients with randomly generated demands during the workday that must be served as soon as possible. According to the actual medical needs of patients, regular patients are segmented into multiple classes with different cancelation rates, no‐show probabilities, unit value contributions, and average service times. Management makes admission decisions on whether or not to accept a service request from a regular patient during the booking horizon to improve the overall value that could be generated during the workday. The decisions should be made by considering the cancelation and no‐show behavior of booked patients as well as the emergency patients that would have to be served because any overtime service would lead to higher costs. We studied the optimal admission decision using a continuous‐time discrete‐state dynamic programming model. Identifying an optimal policy for this discrete model is analytically intractable and numerically inefficient because the state is multidimensional and infinite. We propose to study a deterministic counterpart of the problem (i.e., the fluid control problem) and to develop a time‐based fluid policy that is shown to be asymptotically optimal for large‐scale problems. Furthermore, we propose to adopt a mixed fluid policy that is developed based on the information obtained from the fluid control problem. Numerical experiments demonstrate that this improved policy works effectively for small‐scale problems. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 287–304, 2016
