论边防警察的心理应激与应对

心理应激是一种特殊的情绪状态,在这种情绪状态下个体会有很多特殊的反应和举动。边防警察由于其工作的特殊性,难免会产生心理应激。边防警察的心理应激源包括工作方面、环境方面、生活方面。分析了边防警察心理应激的类型及表现,主要从培养品质和意志,学会放松,取得社会、家人、亲友的支持和理解,加强心理训练等方面论述了应对边防警察心理应激的措施。     

军队院校文化管理模式初探

管理现代化是一所大学成功办学的基本标志。军队院校文化管理理论的提出是时代发展的必然要求。军队院校实施文化管理的核心内容及基本策略就是建设好、使用好自己的特色文化,为此,管理者应注意处理好有为管理与无为管理、柔性管理与刚性管理、部门主管与分工合作、硬件投入与软件提升四个方面的关系。

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     

开放式CAD图形库的建造与管理

针对目前大多数CAD系统中图形库存在的通用性差、开发效率低、可维护性和可移植性差等方面的问题,提出建造和管理开放式CAD图形库的方法。按此法建造的CAD图形库可相对整个CAD系统独立,对各级用户具有良好的透明度,便于进行二次开发,便于维护和扩充,从而提高设计效率。     

Optimal control policies for an inventory system with commitment lead time

We consider a firm which faces a Poisson customer demand and uses a base‐stock policy to replenish its inventories from an outside supplier with a fixed lead time. The firm can use a preorder strategy which allows the customers to place their orders before their actual need. The time from a customer's order until the date a product is actually needed is called commitment lead time. The firm pays a commitment cost which is strictly increasing and convex in the length of the commitment lead time. For such a system, we prove the optimality of bang‐bang and all‐or‐nothing policies for the commitment lead time and the base‐stock policy, respectively. We study the case where the commitment cost is linear in the length of the commitment lead time in detail. We show that there exists a unit commitment cost threshold which dictates the optimality of either a buy‐to‐order (BTO) or a buy‐to‐stock strategy. The unit commitment cost threshold is increasing in the unit holding and backordering costs and decreasing in the mean lead time demand. We determine the conditions on the unit commitment cost for profitability of the BTO strategy and study the case with a compound Poisson customer demand.     

Stochastic modeling for computational warranty analysis

We examine two key stochastic processes of interest for warranty modeling: (1) remaining total warranty coverage time exposure and (2) warranty load (total items under warranty at time t). Integral equations suitable for numerical computation are developed to yield probability law for these warranty measures. These two warranty measures permit warranty managers to better understand time‐dependent warranty behavior, and thus better manage warranty cash reserves. © 2005 Wiley Periodicals, Inc.
