着眼装备信息化的长远发展积极科学的建设好装备基础数据库

信息化战争是信息化武器装备发展到成熟时期、新军事变革发展到高级阶段、社会变革跨入信息时代的最新战争模式。信息化战争离不开信息化的装备,装备信息化的建设也离不开装备管理的信息化,装备管理信息化的水平对装备信息化本身的发展会起到很重要的促进作用,装备基础数据库则是装备管理信息化的基础。本文将重点分析装备基础数据库建设的现状,阐述科学建设装备基础数据库的好处,并提出对建设通用装备基础数据库的几点思考。     

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     

振级落差和插入损失对应关系的研究

评价隔振系统的隔离效果到底是用振级落差好,还是用插入损失好,一直存在着争议．尽管有关的国家标准和军标已明确规定,用振级落差作为舰船上各类隔振装置隔振效果的评价指标,但在讨论具体问题时,有人仍然提出插入损失的对应值问题．作者在理论上探讨了单自由度线性隔振系统的振级落差与插入损失的表达式,及其在舰船条件下的定量对应关系,从而回答了上面提出的问题

论汉魏之际羌胡化的凉州军事集团

东汉末年,"习于夷风",羌胡化的凉州军事集团曾一度席卷关洛京畿,对东汉帝国的中枢形成毁灭性的打击。董卓、李催对二京的破坏,是反文明、反人类的行为。此风一开,影响恶劣,曹操、孙权在征战中时常屠城,滥杀无辜。关西兵精悍,具有强大的战斗力,然凉州武将性多疑忌,反覆无常。其部又"莫相归服,军无适主",缺乏凝聚力,加之"凉州寡于学术",得不到士大夫的有力支持,故最终导致了凉州军事集团的灰飞烟灭。
