雷达业务与技术勤务管理系统(RDMS)

智能化和工具化是RDMS的主要设计思想和技术特色,体现在RDMS的基于规则的计算工具、通用文档管理子系统和汉字通用报表工具。本文着重讨论这三部分的设计与实现问题。     

Fuzzy-AHP在军械软科研管理中的应用

本文采用群组Fuzzy-AHP对军械管理软科研成果进行综合评价,给出了一个简便、可行的评价标准。军械管理系统是一个复杂的开放系统,有诸多不确定的因素存在,我们认为要提出一个适应性较强的、具有浓缩内涵和广大外延的军械管理软科研成果的评价标准,必须遵守局部服从整体、近期效果与远期效果相结合、定性分析与定量分析相结合的原则。针对军械管理软科学研究的特点,本文建立了表征软科学成果的包括价值、质量、投入在内的指标体系,构成了多目标决策数学模型,运用层次分析的方法,结合模糊评判的手段,给出了模糊评判矩阵、综合评分与排序。

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。     

UNIX 网络性能管理的流量监测技术研究

网络性能管理的主要目标是高性能和高吞吐量。标准UNIX系统缺乏对网络的流量的有效管理。本文研究了在标准UNIX网络实现性能管理中的网络流量监测、主机网络／系统状况动态检测等技术，依据检测结果用户可以进行网络动态配置或重新分配网络资源，从而改善UNIX系统的网络性能及吞吐量等技术。结果表明所提供的技术手段是有效的。

Callable products for an implicit time model with dependent demands

Capacity providers such as airlines and hotels have traditionally increased revenues by practicing market segmentation and revenue management, enabling them to sell the same capacity pool to different consumers at different prices. Callable products can enhance profits and improve consumers' welfare by allowing the firm to broker capacity between consumers with different willingness to pay. A consumer who buys a callable product gives the capacity provider the right to recall capacity at a prespecified recall price. This article studies callable products in the context of the model most commonly used in industry, which handles time implicitly imposing fewer restrictions on the nature of randomness compared to the Poisson arrival process favored in academia. In the implicit time model, capacity providers set booking limits to protect capacity for future high-fare demand. Our numerical study identifies conditions where callable products result in significant gains in profits.     

风险评价在军队营区环境管理中的应用

分析了军队营区环境风险的概念,认为要消减军队营区环境风险,不能仅考虑降低风险概率或风险后果,而应从风险概率与风险后果两者的乘积效应出发,通过综合分析和控制环境风险系统来解决;着重探讨了军队营区环境风险评价的内容和方法,包括环境风险识别、环境风险预计、环境风险评价与对策.军队营区环境风险评价可从二个层次进行评价一是从事件及与之有关联的周围环境条件出发,按"环境风险系统"的思路,从风险源、初级控制条件、二级控制条件、目标4个阶段进行评价;二是从事件或行动的具体问题出发,评价其风险的重大性和可接受性.最后讨论了军队营区环境风险管理的内容和方法.     

Managing components for assemble‐to‐order products with lead‐time‐dependent pricing: The full‐shipment model

We study a component inventory planning problem in an assemble‐to‐order environment faced by many contract manufacturers in which both quick delivery and efficient management of component inventory are crucial for the manufacturers to achieve profitability in a highly competitive market. Extending a recent study in a similar problem setting by the same authors, we analyze an optimization model for determining the optimal component stocking decision for a contract manufacturer facing an uncertain future demand, where product price depends on the delivery times. In contrast to our earlier work, this paper considers the situation where the contract manufacturer needs to deliver the full order quantity in one single shipment. This delivery requirement is appropriate for many industries, such as the garment and toy industries, where the economies of scale in transportation is essential. We develop efficient solution procedures for solving this optimization problem. We use our model results to illustrate how the different model parameters affect the optimal solution. We also compare the results under this full‐shipment model with those from our earlier work that allows for multiple partial shipments. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007
