图文信息直观方便易于理解,是用户喜闻乐见的一种信息表达方式。本文提出了一个开发图文综合信息分析管理系统的方法。该系统从技术上来看,归结为图文解释器(推理机)和图文的知识表示两大部分,并提出了一个称之为“面向问题的信息导向器(Question-Oriented Information Navigator)”的图形信息组织结构。图文解释器是该系统的核心,它在运行过程中根据用户提出的问题或对问题的选择来自动组织并解释知识库中的知识,以图文并茂或动态图形变化的形式显示在屏幕上或打印出来,使决策者能迅速直观地了解各方面的信息,对决策过程提供有力的支持。最后,给出了该系统应用在“宏观经济智能人—机决策支持系统(MEIDSS)”中的实例。  相似文献

A calculus for services innovation   总被引:1,自引:1,他引:0  
Innovation in the services area - especially in the electronic services (e-services) domain - can be systematically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. More specifically, there are four customer drivers (i.e., collaboration, customization, integration and adaptation), three business foci (i.e., creation-focused, solution-focused and competition-focused), six business principles (i.e., reconstruct market boundaries, focus on the big picture not numbers, reach beyond existing demand, get strategic sequence right, overcome organizational hurdles and build execution into strategy), eight technical enablers (i.e., software algorithms, automation, telecommunication, collaboration, standardization, customization, organization, and globalization), and six attributes of decision informatics (i.e., decision-driven, information-based, real-time, continuously-adaptive, customer-centric and computationally-intensive). It should be noted that the four customer drivers are all directed at empowering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive customized or personalized attention, access an integrated system or process, and obtain adaptive real-time or just-in-time input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can mitigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP metric that can adequately measure the growing knowledge economy,  相似文献

战争决策行为建模与仿真的研究   总被引:4,自引:2,他引:2  
魏宾  胡晓峰  司光亚 《系统仿真学报》2003,15(12):1678-1682
目前,世界上局部战争和国际危机此起彼伏,因此,运用科学的手段和方法,展开针对可能引发军事冲突或爆发战争的危机的决策行为的研究,具有重大的现实意义。它有助于揭示战争危机的内在规律,使得危机朝着我们期望的方向发展。本文以美国为研究对象,全面阐述了影响个人决策、组织决策和群体决策的非理性行为约束变量,深入研究了美国战争危机的决策机构,分析了其决策过程。以此为基础,采用新的建模与仿真技术-agent技术,探讨了个人决策、组织决策和群体决策的agent技术建模机制,建立了基于Agent技术的战争决策行为模型体系结构,并根据编程实践,ZEUS和MAGE两种agent开发系统正确比较的基础上,给出了在两种开发系统下实现战争决策行为模型的编程构想。它为分析美国战争危机决策提供了理论和方法上的指导,具有很强的实践意义和现实意义。  相似文献

由于脉冲噪声下的最优检测要求非线性运算, 信号检测常采用零记忆非线性变换接匹配滤波的检测结构。本文系统地综述了脉冲噪声下的非线性变换设计, 梳理了国内外研究在噪声模型、非线性函数和设计方法3个方面的工作, 并总结研究路线和规律。首先, 脉冲噪声模型常采用对称α稳定分布、Class A分布、高斯混合分布及其他混合分布。其次, 以拖尾函数为特征, 非线性函数模式可分为传统削波/置零、多区域组合拖尾、单参数特定拖尾、单参数非分段函数以及双参数可变拖尾。然后, 在设计方法上, 分析近似和正态变换的思路比较直观, 而最大信噪比和最大效能准则与检测性能有直接联系。之后, 总结了常见研究路线和主要研究成果的共性规律。最后, 探讨了噪声分布未知和效能寻优简化的问题, 展望未来可能的研究点。  相似文献

Manufacturing and services: From mass production to mass customization   总被引:3,自引:1,他引:2  
Manufacturing and services constitute two of the five sectors of every country’s economy;depending on the maturity of the economy,they are-in terms of employment-typically the two largest sectors.The outputs or products of an economy can also be divided into goods products(due to manufacturing,construction,agriculture and mining) and services products.To date,the goods and services products have,for the most part,been mass produced;it is the premise of this paper that recent technological advances-including flexible manufacturing,cloud computing,nanotechnology and smart sensing-can better enable the transformation from mass production to mass customization.We regard mass customization as the simultaneous and real time management of supply and demand chains,based on a taxonomy that can be defined in terms of its underpinning component and management foci.From a components perspective,we first consider the value chain of supplier,manufacturer,assembler,retailer,and customer,and then develop a consistent set of definitions for supply and demand chains based on the location of the customer order penetration point.From a management perspective,we classify the methods that are employed in the management of these chains,based on whether supply and/or demand are flexible or fixed.Interestingly,our management taxonomy highlights a very critical research area at which both supply and demand are flexible,thus manageable.Simultaneous management of supply and demand chains sets the stage for mass customization which is concerned with meeting the needs of an individualized customer market.Simultaneous and real time management of supply and demand chains set the stage for real time mass customization(e.g.,wherein a tailor first laser scans an individual’s upper torso and then delivers a uniquely fitted jacket within a reasonable period,while the individual is waiting).The benefits of real time mass customization cannot be over-stated as goods and services become indistinguishable and are co-produced-as "servgoods"-in real time,resulting in an overwhelming economic advantage.  相似文献

基于耦合协调度测度模型、主成分分析以及面板门限回归模型,运用2013~2017年我国30个省市的面板数据,以产学研耦合协调度为门限变量,将区域R&D投入划分为R&D人员投入与R&D经费投入,探究R&D人员投入与R&D经费投入对科技绩效产生的异质性影响。实证结果表明:当以产学研耦合协调度为门限变量时,R&D人员投入与R&D经费投入均与滞后3期的科技绩效存在明显的双门限效应;R&D人员投入对科技绩效的正向作用随着门槛值的提升不断增大,当产学研耦合协调度高于0.6135时,R&D人员投入对科技绩效产生显著的正向作用;R&D经费投入对科技绩效并不总是产生正向促进作用,当区域产学研耦合协调度小于0.5290时,R&D经费投入会对科技绩效产生负向作用;当区域产学研耦合协调度高于0.5290时,R&D经费投入对科技绩效产生正向作用;并且,R&D人员投入对科技绩效产生的作用更为显著。  相似文献
