A framework for virtual enterprise support services 一个用于虚拟企业支持服务的框架
V. Ouzounis, V. Tschammer
The main scope of this paper is to present a set of enabling services that support the establishment and management of Virtual Enterprises and the integration and interoperation of business processes. Based on a virtual enterprise life-cycle model that we propose, different business domains can integrate their business processes in order to provide transparently services to the end-users and customers of the Virtual Enterprise (VE). The appropriate enabling services are identified, analyzed and certain details regarding their design is given. These enabling services are the VE contract manager, the BP administrator, and the BP controller. Underlying services needed for the integration and execution of shared business processes are also proposed. Our proposed enabling services reduce the cost of development, maintenance and integration of shared business processes in VEs by applying interoperable, distributed object oriented technologies.
本文的主要范围是介绍一组支持虚拟企业的建立和管理以及业务流程的集成和互操作的启用服务。基于我们提出的虚拟企业生命周期模型,不同的业务领域可以集成它们的业务流程,以便向虚拟企业(VE)的最终用户和客户提供透明的服务。识别和分析了适当的启用服务,并给出了有关其设计的某些细节。这些启用服务包括VE合同管理器、BP管理员和BP控制器。还提出了集成和执行共享业务流程所需的底层服务。我们提出的启用服务通过应用可互操作的分布式面向对象技术,降低了ve中共享业务流程的开发、维护和集成成本。

Global enterprise resource planning implementation 全球企业资源规划实施
C. Holland, B. Light
The globalisation of markets is having a profound effect on business and information technology strategies of individual organisations. The move away from nationally focused business units to a global product-market focus requires an effective international coordination of a firm's activities. To support a global outlook, many firms are implementing enterprise resource planning (ERP) systems. Although ERP has become the de facto standard for international organisations there are few documented examples of implementation. This paper seeks to make a contribution to this important area. A case study analysis of the strategic context and implementation of a global ERP project in a multinational textiles group is presented. It illustrates the transformation of a conglomerate of nationally organised businesses into a pan-European organisation. The case analysis demonstrates the organisational and technical complexity of ERP implementation and identifies the factors that determined the total cost of the system. Opportunities for future research are outlined.
市场的全球化对个别组织的商业和信息技术战略产生了深远的影响。从以国家为重点的业务单位转向以全球产品市场为重点,需要对公司的活动进行有效的国际协调。为了支持全球前景,许多公司正在实施企业资源规划(ERP)系统。尽管ERP已经成为国际组织事实上的标准,但很少有文件证明的实施例子。本文力图对这一重要领域作出贡献。一个案例研究分析的战略背景和实施的全球ERP项目在一个跨国纺织集团提出。它说明了一个由全国性企业组成的企业集团向一个泛欧洲组织的转变。案例分析展示了ERP实施的组织和技术复杂性,并确定了决定系统总成本的因素。概述了未来研究的机会。

Designing for low power in complex embedded DSP systems 复杂嵌入式DSP系统的低功耗设计
C. Gebotys, R. Gebotys
This paper presents an empirical methodology for low power driven complex DSP embedded systems design. Unlike DSP design for high performance, research of low power DSP design has received little attention, yet power dissipation is an increasingly important and growing problem. Highly accurate power prediction models for DSP software are derived. Unlike previous techniques, the methodology derives software power prediction models using statistical optimization and it is verified with real power measurements. The approach is general enough to be applied to any embedded DSP processor. Results from two different DSP processors and over 180 power measurements of DSP code show that power can be predicted far embedded systems design with less than 4% error. This result is important for developing a general methodology for power characterization of embedded DSP software since low power is critical to complex DSP applications in many cost sensitive markets.
本文提出了一种低功耗驱动复杂DSP嵌入式系统设计的经验方法。与高性能的DSP设计不同,低功耗DSP设计的研究很少受到重视,而功耗是一个越来越重要和日益突出的问题。推导了DSP软件的高精度功率预测模型。与以往的技术不同,该方法通过统计优化推导出软件功率预测模型,并通过实际功率测量进行验证。该方法具有通用性,适用于任何嵌入式DSP处理器。对两种不同的DSP处理器和180多个DSP代码的功率测量结果表明,对嵌入式系统设计的功率预测误差小于4%。这一结果对于开发嵌入式DSP软件功率特性的通用方法非常重要,因为在许多成本敏感的市场中,低功耗对复杂的DSP应用至关重要。

The P-Mesh-a commodity-based scalable network architecture for clusters p - mesh——一种基于商品的集群可扩展网络架构
B. Nitzberg, C. Kuszmaul, I. Stockdale, J. Becker, John Jiang, P. Wong
We designed a new network architecture, the P-Mesh, which combines the scalability and fault resilience of a torus with the performance of a switch. We compare the scalability, performance and cost of the hub, switch, torus, tree and P-Mesh architectures. The latter three are capable of scaling to thousands of nodes. However, the torus has severe performance limitations with that many processors. The tree and P-Mesh have similar latency, bandwidth and mid-bisection bandwidth, but the P-Mesh outperforms the switch architecture (a lower bound for tree performance) on 16-node NAS parallel benchmark tests by up to 23%, and costs 40% less. Furthermore, the P-Mesh has better fault resilience characteristics. The P-Mesh architecture trades increased management overhead for lower cost, and is a good bridging technology, while the price of tree uplinks is expensive.
我们设计了一种新的网络架构,P-Mesh,它结合了环面的可扩展性和故障恢复能力以及交换机的性能。我们比较了集线器、交换机、环面、树和P-Mesh架构的可扩展性、性能和成本。后三者能够扩展到数千个节点。然而,对于这么多处理器,环面有严重的性能限制。树和P-Mesh具有相似的延迟、带宽和中平分带宽,但在16节点NAS并行基准测试中,P-Mesh的性能比交换机架构(树性能的下限)高出23%,成本低40%。此外,P-Mesh具有较好的故障恢复特性。P-Mesh结构以增加的管理开销换取较低的成本,是一种很好的桥接技术,而树上行链路的价格昂贵。

Wicked decision problems in remote health care: telemedicine as a tool for sensemaking 远程医疗中的邪恶决策问题:远程医疗作为一种意义生成工具
D. Paul
Health care providers often face different types of problems than uncertainty-those involving wicked decision problems. Whereas uncertainty reduction requires increased information processing capabilities, wicked decision problems require both increased information processing and sensemaking capabilities. Sensemaking is about interpreting and deriving meaning from multiple, conflicting cues. Case studies of three teleconsultation projects utilized for both sensemaking and information processing are presented. In addition to impacting the cost and quality of care provided in remote areas, telemedicine networks utilized to reduce uncertainty may experience lower utilization rates, while telemedicine utilized to address wicked decision problems may experience increased utilization rates.
医疗保健提供者经常面临不同类型的问题,而不是不确定性——那些涉及邪恶决策问题的问题。减少不确定性需要提高信息处理能力,而邪恶的决策问题需要提高信息处理和意义生成能力。意义构建是关于从多个相互矛盾的线索中解释和推导意义。本文介绍了三个远程咨询项目的案例研究,这些项目同时用于语义生成和信息处理。除了影响偏远地区提供的医疗服务的成本和质量外,用于减少不确定性的远程医疗网络的使用率可能会降低,而用于解决不良决策问题的远程医疗网络的使用率可能会提高。

Dynamic visual metaphors for news story abstractions 新闻故事抽象的动态视觉隐喻
B. Boguraev, R. Bellamy, Christopher Kennedy
We describe a dynamic document genre for online news, specifically designed to support end users in both easily skimming news stories as well as reading them in-depth. Through careful analysis of the needs of online news readers, and understanding the opportunities and constraints of the computational medium, we set out to define characteristics of a document management environment which uses linguistically-intensive content analysis techniques to derive document abstractions usable as 'zooming' windows into and out of documents. The notion of flexible mediation between progressively richer, and more informative, layers of document content defines the core underlying characteristic of a dynamic document genre. We prototyped and deployed three examples of dynamic document viewers that characterize this new genre. The design incorporates a novel mix of: state-of-the-art linguistic analysis techniques that produces capsule document overviews, novel temporal typography techniques that allows us to dynamically change how these overviews are presented to the reader, specialized search and filter mechanisms to cull collections of relevant documents from the Web, and large screen displays to facilitate peripheral awareness of constantly changing news feeds.
我们为在线新闻描述了一种动态文档类型,专门为支持终端用户轻松浏览新闻故事以及深入阅读而设计。通过仔细分析在线新闻读者的需求,并了解计算媒体的机会和限制,我们开始定义文档管理环境的特征,该环境使用语言密集型内容分析技术来派生文档抽象,可用于“缩放”窗口来进出文档。在越来越丰富、信息量越来越大的文档内容层之间灵活中介的概念定义了动态文档类型的核心潜在特征。我们原型化并部署了三个动态文档查看器的示例,它们代表了这种新类型。该设计结合了以下新组合:最先进的语言分析技术,可以生成胶囊文档概述;新颖的时间排版技术,允许我们动态地改变这些概述呈现给读者的方式;专门的搜索和过滤机制,可以从网络中挑选出相关文档集合;以及大屏幕显示,可以促进对不断变化的新闻源的外围感知。

Web information systems: introduction to the minitrack Web信息系统:微轨介绍
T. Isakowitz, M. Bieber, M. Koufaris
The scope of web-based applications has grown enormously, encompassing now four general kinds of Web-based systems: (1) Intranets, to support internal work, (2) Web presence sites that are marketing tools with the goal of reaching consumer outside of the firm, (3) Electronic Commerce systems that support consumer interaction, such as on-line shopping, and (4) a blend of internal and external systems to support business-to-business communication, commonly called Extranets.Thus, the web platform has transformed itself in the few years from a mere marketing presence to a platform that can support all facets of organizational work. As a result, more important IS efforts are geared towards exploiting the benefits of this platform, leading to the development of information systems based on Web technology, what we call "Web Information Systems" (WISs) [1]. We believe that this type of systems will become as commonplace as client/server systems did a decade ago, but with an exponentially higher impact on our lives, if anything, simply because the WWW has the potential of reaching a much wider audience than client/server systems based on proprietary networks.
基于Web的应用程序的范围已经大大扩大,现在包含了四种基于Web的系统:(1)支持内部工作的内部网;(2)以接触公司外部消费者为目标的营销工具的Web站点;(3)支持消费者交互的电子商务系统,如在线购物;(4)支持企业对企业通信的内部和外部系统的混合,通常称为外联网。因此,网络平台在几年的时间里已经从一个单纯的营销平台转变为一个可以支持组织工作的各个方面的平台。因此,更重要的信息系统努力是为了利用这个平台的好处,导致基于Web技术的信息系统的发展,我们称之为“Web信息系统”(WISs)[1]。我们相信这种类型的系统将会像十年前的客户端/服务器系统一样普遍,但如果有什么不同的话,它对我们生活的影响将会呈指数级增长,这仅仅是因为WWW比基于专有网络的客户端/服务器系统有潜力接触到更广泛的受众。

A virtual electronic call center solution for mass customization 大规模定制的虚拟电子呼叫中心解决方案
K. Turowski
Since mass customization is becoming more and more important as a marketing strategy, companies have to produce highly specialized and individualized products. To satisfy these customer demands, manufacturers, suppliers and retailers are building networks and connecting their application systems together. For this, electronic commerce techniques are a considerable asset for speeding up the inter-company coordination process. In this paper, an approach is discussed that supports distributed but logically integrated business processes in which complex and hard-to-standardize data occur, by applying e-commerce techniques. By doing so, the inter-company data exchange, planning and coordination of the production processes in the case of mass customization are improved.
由于大规模定制作为一种营销策略变得越来越重要,企业必须生产高度专业化和个性化的产品。为了满足这些客户需求,制造商、供应商和零售商正在建立网络并将他们的应用系统连接在一起。为此,电子商务技术是加速公司间协调过程的重要资产。本文讨论了一种方法,该方法通过应用电子商务技术来支持分布式但逻辑集成的业务流程,其中会出现复杂且难以标准化的数据。通过这样做,可以改善大规模定制情况下公司间的数据交换、生产过程的规划和协调。

Parallel string matching algorithms based on dataflow 基于数据流的并行字符串匹配算法
J. H. Park, K. M. George
This paper presents efficient dataflow schemes for parallel string matching. Two subproblems known as the exact matching and the k-mismatches problems are covered. Three parallel algorithms based on multiple input (and output) streams are presented. Time complexities of these parallel algorithms are O((n/d)+/spl alpha/), O/spl les//spl alpha//spl les/m, where n and m represent lengths of reference and pattern strings (n/spl Gt/m) and d represents the number of streams used (the degree of parallelism). We can control the degree of parallelism by using variable number (d) of input (and output) streams. These performances are better than those found in the literature. These algorithms present three different methods to design special purpose systolic array hardware for string matching. With linear systolic array architecture, m PEs are needed for serial design and d*m PEs are needed for parallel design.
本文提出了并行字符串匹配的有效数据流方案。两个子问题被称为精确匹配和k-不匹配问题被涵盖。提出了三种基于多输入(和输出)流的并行算法。这些并行算法的时间复杂度为O((n/d)+/spl alpha/), O/spl les//spl alpha//spl les/m,其中n和m表示引用和模式字符串的长度(n/spl Gt/m), d表示使用的流的数量(并行度)。我们可以通过使用输入(和输出)流的可变数(d)来控制并行度。这些表演比文学作品中的表演要好。这些算法提供了三种不同的方法来设计用于字符串匹配的专用收缩阵列硬件。在线性收缩阵列结构下,串行设计需要m个pe,并行设计需要d*m个pe。

Collaborative best-effort real-time agents-a new paradigm 协作的最佳努力实时代理——一个新的范例
J. Jehuda
This paper introduces a novel new class of network-based software agents, called CoBERT agents, because they are designed to cooperate in the best-effort maximization of global system objectives for a dynamic set of agents with evolving characteristics, while reliably accommodating real-time requirements, as well. Cooperation is achieved by supporting mobility within a subnet of processing nodes, morphability between sets of available workpoints, decision epochs for shifting to other nodes and/or workpoints, appropriate state-dependent functions for expressing decision options and implications, and an appropriate protocol for sharing this information with meta-control agents charged with continuously monitoring the network and making the best-effort decisions. The timely scheduling of hard and soft real-time activities is accomplished even though there is no a priori knowledge as to where the agent will run and with which additional CoBERT agents. Such capabilities are essential to future agent-based systems, as real-time grows pervasive and as dynamic sets of evolving agents populate our networks. A distributed integrated HIL simulator is used to introduce the real-time domain and to demonstrate how the CoBERT agent paradigm might be applied.
本文介绍了一类新的基于网络的软件代理,称为CoBERT代理,因为它们被设计为在具有不断发展特征的动态代理集的全局系统目标的最佳努力最大化中合作,同时可靠地适应实时需求。协作是通过支持处理节点子网内的移动性、可用工作点集之间的形态、转移到其他节点和/或工作点的决策时间、用于表达决策选项和含义的适当状态依赖函数,以及用于与负责持续监控网络并做出最佳决策的元控制代理共享此信息的适当协议来实现的。即使没有关于代理将在哪里运行以及与哪些其他CoBERT代理一起运行的先验知识,也可以完成硬实时和软实时活动的及时调度。这样的能力对于未来的基于代理的系统来说是必不可少的,因为实时越来越普遍,并且动态的不断发展的代理填充了我们的网络。使用分布式集成HIL模拟器来引入实时域,并演示如何应用CoBERT代理范式。
