战争决策行为建模与仿真的研究 总被引:4,自引:2,他引:2
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

观点作为一种舆情,意见,态度的表现形式广泛存在于人们的生活中,研究观点的演变对理清观点演变机制,促进舆情合理治理具有重要意义。鉴于现有研究缺乏对二元观点动力学的相关介绍以及割裂了二元与群体观点动力学之间的联系,未能全面揭示观点动力学研究现状,因此,对国内外观点动力学研究现状进行了梳理和总结。其中,从研究方法和交互特征视角对二元观点动力学模型及其研究现状进行了介绍,从个体特征,行为特征,观点特征,外部环境,观点动力学的应用视角对群体观点动力学研究成果进行了梳理。最后,基于现有研究,明确了观点动力学未来需要进一步解决的问题:实证视角下的观点演化机制,意见的强化和争议的消减,观点的演化与群体决策之间的联系。 相似文献

Modern modes of transport, in the developed world, were designed to achieve higher mobility (or speed) and increased accessibility, all in the name of growth and human progress. However, in the course of providing for this higher mobility, through the rapid expansion of the transport system, we have ended up with a condition of imbalanced mobility, which we refer to as "hypermobility," particularly with reference to the automobile mode. Ironically, this very expansion of the transport network, with the objective of providing higher transport speeds, has resulted in traffic congestion that has drastically reduced mobility and accessibility, thereby lowering business productivity, increasing fuel consumption, increasing pollution, and robbing the public of billions of hours of valuable time. In light of the present unsustainable conditions, we examine and analyze the concepts of mobility through an inquiry of time, space, human freedom, and social justice from an ethical and systemic viewpoint. We conclude that if hypermobility is not dealt with both as an individual and as a collective responsibility, the challenge to transport ethics and its systemicity could be further impaired. 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

运用多目标模糊优化模型,对新疆奇台县农业种植结构优化配置进行了探讨。结果表明,要使其农业综合效益最大,必须要调整农业种植结构和减少农作物种植面积。在现有农业供水量不足的情况下,小麦、大麦面积需要逐渐减少,而玉米及经济作物(油料、甜菜)的面积应适当增加。相对2005年,在P=50%的灌溉用水的保证率下,2010年小麦、大麦种植面积应分别减少14.9%、19.2%,而玉米、油料、甜菜则应分别增长4.7%、23.4%、75.7%;到2015年,前两者需减少15.0%和20.6%,后3者增加2.6%、23.1%、75.0%。同时,在这两个时间段农田总面积将减少1 580 hm2、1 935 hm2,使农作物种植面积和水量实现最优分配。 相似文献

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
