Systems Engineering (SE) and Concurrent Engineering (CE) implies sharing of information, data, process and knowledge [20] across different levels in an enterprise. Division of work into classes and then to the work-groups or to the concurrent sub-teams is one form of sharing large organizations like Ford Motor and General Motors have used [29]. Other forms of sharing are governed by the state of computer communications, workstation and database technologies [9]. For accomplishing the needed collaboration (and to facilitate concurrent engineering), several concepts and models for work-group computing were tried at Delphi Divisional units of Electronic Data Systems (EDS) and General Motors. Based on such experiences, the paper describes Systems Engineering and CE techniques for sharing information in a concurrent engineering organization, which has been found most effective for collaborating knowledge among a set of multidisciplinary work-groups, array of computers and processes.  相似文献

The German manufacturing industry is forced to evolve its processes, techniques, and organizations due to increasing global competition and progressive sustainability requirements. In this context, the soaring possibilities of bio- and information technology have recently let few authors develop the vision of a biological transformation of manufacturing, a concept that to date has been barely concrete to politicians, scientists, and managers. In this paper, we present results of the first systematic assessment of the biological transformation of the German manufacturing industry. We chose a combination of the Delphi method and scenario planning in order to assess key technologies, determine the status quo of Germany and provide a forecast of potential developments. Thereupon, we identify ten fields of action for setting the course for a sustainable industrial value creation. We conclude with a summary and recommendations for decision makers in politics, industries and research.  相似文献

Electronic business-to-business (B2B) marketplaces have been one of the most discussed topics in recent times. In the beginning they were seen euphorically, but today many observers are skeptical. In order to dissolve this uncertainty we conducted a Delphi survey after the E-Commerce Hype. The results are used to establish a reliable forecast about the development of electronic B2B marketplaces in Germany by comparing them with theoretical expectations. As theoretically assumed, it is predicted that this phenomenon will play a major role within intercompany coordination in selected areas. It is anticipated that streamlining information processes will be so beneficial for companies that they will not be able to afford not having this new institution.  相似文献

We inferred business rules for business/ICT alignment by applying a novel rule induction algorithm on a data set containing rich alignment information polled from 641 organisations in 7 European countries. The alignment rule set was created using AntMiner+, a rule induction technique with a reputation of inducing accurate, comprehensible, and intuitive predictive models from data. Our data set consisted of 18 alignment practices distilled from an analysis of relevant publications and validated by a Delphi panel of experts. The goal of our study was to describe practical guidelines for managers in obtaining better alignment of ICT investments with business requirements. Our obtained rule set showed the multi-disciplinary nature of B/ICT alignment. We discuss implication of the alignment rules for practitioners.  相似文献

Abstract

In this paper, we identify processes associated with “Tactical IT-Business Alignment”, illustrate four types of alignment states resulting from “strategic” and “tactical” alignment levels, and propose alignment-related managerial actions appropriate for each type. Our results are based on about 45 hours of interviews with about 30 senior, middle and junior managers from IS and other functions, and from company records, in an investigation of four organizations.  相似文献

The Delphi method has proven a popular tool in information systems research for identifying and prioritizing issues for managerial decision-making. However, many past studies have not adopted a systematic approach to conduct a Delphi study. This article provides rigorous guidelines for the process of selecting appropriate experts for the study and gives detailed principles for making design choices during the process that ensure a valid study. A detailed example of a study to identify key factors affecting the diffusion of e-commerce in Sub-Saharan Africa illustrates the design choices that may be involved. We conclude with suggestions for theoretical applications.  相似文献

The main purpose of this study was to establish Information Literacy Competence Standards for Elementary and High School Teachers. To establish these standards a set of two expert round-table discussions and three rounds of Delphi Technique surveys were employed. Ten participants including field scholars, information professionals were invited to the expert round-table for open discussions on definitions, framework, and items of information literacy competence. A questionnaire for the “Delphi Technique Survey” was developed based on the results acquired from the round-table discussions. The resulting questionnaire was distributed to another group of 33 participants which included graduate school deans of Information Education, professors, school principals, department directors and teachers, and information professionals. After three rounds of Delphi Technique Surveys with these participants, the “Information Literacy Competence Standards for Elementary and High School Teachers” was established. Three levels (standards, main indicators, and secondary indicators) and three dimensions (knowledge, skills, and attitudes) were identified. Distinguished from existing research which over-emphasizes the dimensions of knowledge and skills, the present study found that the dimension “attitude” is the most powerful force for promoting teachers’ information literacy competence and their willingness to apply information technology in teaching. It is hoped that the proposed standards could be served as a self-evaluation tool for teachers as well as the basis for staffing and training programs for elementary and high school teachers in Taiwan.  相似文献

Using qualitative methods, this paper explores how impact sourcing (ImS) ventures frame their activities to marginalized communities. In doing so, the paper attempts to unearth the social–psychological processes undergirding ImS strategies. The findings highlight the difficulties faced by ImS ventures in operationalizing their strategic intent. More specifically, the paper provides insights into how different and diverse framings are used by ImS ventures to influence the local community. From a strategic perspective, the paper suggests that framings related to progress, family, material benefit and egalitarianism can help overcome the inevitable tensions and misunderstandings with the community. Drawing on the findings, we develop a process model that describes how competing framings of an ImS venture and the community could eventually align. Theoretically, the paper illuminates the day to day micro‐processes of reality negotiation between socially driven information technology – business process outsourcing businesses and the local communities they seek to impact.  相似文献

Increasingly, business processes are being controlled and/or monitored by information systems. As a result, many business processes leave their “footprints” in transactional information systems, i.e., business events are recorded in so-called event logs. Process mining aims at improving this by providing techniques and tools for discovering process, control, data, organizational, and social structures from event logs, i.e., the basic idea of process mining is to diagnose business processes by mining event logs for knowledge. In this paper we focus on the potential use of process mining for measuring business alignment, i.e., comparing the real behavior of an information system or its users with the intended or expected behavior. We identify two ways to create and/or maintain the fit between business processes and supporting information systems: Delta analysis and conformance testing. Delta analysis compares the discovered model (i.e., an abstraction derived from the actual process) with some predefined processes model (e.g., the workflow model or reference model used to configure the system). Conformance testing attempts to quantify the “fit” between the event log and some predefined processes model. In this paper, we show that Delta analysis and conformance testing can be used to analyze business alignment as long as the actual events are logged and users have some control over the process.

实体对齐旨在找到位于不同知识图谱中的等效实体,是实现知识融合的重要步骤.当前主流的方法是基于图神经网络的实体对齐方法,这些方法往往过于依赖图的结构信息,导致在特定图结构上训练得到的模型不能拓展应用于其他图结构中.同时,大多数方法未能充分利用辅助信息,例如属性信息.为此,本文提出了一种基于图注意力网络和属性嵌入的实体对齐方法,该方法使用图注意力网络对不同的知识图谱进行编码,引入注意力机制从实体应用到属性,在对齐阶段将结构嵌入和属性嵌入进行结合实现实体对齐效果的提升.在现实世界的3个真实数据集上对本文模型进行了验证,实验结果表明提出的方法在很大程度上优于基准的实体对齐方法.  相似文献

In industrial processes, analyzing and predicting process faults are quite important, which could help operators to take timely and effective responses to ensure process safety and prevent further losses, especially during alarm floods. Various fault analysis methods have been proposed so far, among which the alarm flood sequence alignment (AFSA) methods, unlike other traditional model-based or statistical methods, provide fault inference from the perspective of alarm sequence similarity assessment. A new AFSA method, the match-based accelerated alignment (MAA) is proposed to generate insightful and informative alarm sequence alignments. MAA focuses mainly on alarm match analysis and outperforms other methods in terms of robustness towards nuisance alarms and improved computational efficiency. More importantly, the alarm time information is well considered and explored in MAA, rendering its alignment results capable of revealing the real similarity of alarm floods. Numerical examples and a real chemical plant case are studied to demonstrate the effectiveness and efficiency of the proposed MAA method.  相似文献

实体对齐表示在不同的知识图谱中查找引用相同现实身份的实体。目前主流的基于图嵌入的实体对齐方法中的对齐实体通常具有相似的属性,有效利用属性信息可提升实体对齐效果,同时由于不同知识图谱之间的知识分布差异,仅考虑单个方向的对齐预测会导致预测结果出现偏差。针对上述问题,提出一种改进的跨语言实体对齐方法。利用融合属性信息的双向对齐图卷积网络模型,将前馈神经网络编码实体对应的属性信息与初始的实体嵌入相结合,得到联合属性信息的实体表示,并使用双向对齐机制实现跨语言的实体对齐预测。在3个跨语言数据集上的实验结果表明,该方法通过融合更多的知识图谱信息增强了实体表示能力,并且利用双向对齐机制缓解了数据分布差异问题,相比基于图嵌入的实体对齐方法整体性能更优。  相似文献
