  • By implementing the Systems Engineering process for the aircraft preliminary design, functional analysis study is performed, hence Functional Interface Data Flow(FIDF) and Functional Flow Block Diagram(FFBD) are generated. Based on FIDF and FFBD, allocable and non-allocable design/performance/RM&S requirements are allocated to the appropriate levels. Weight and cost tracking and design margin management methodologies are studied and implemented for the balanced aircraft design.

  • Since 1997, JAB (The Japan Accreditation Board for Conformity Assessment) had started the activity of accreditation for the laboratory based on U.S. PL101-592: the Fastener Quality Act that was signed by President Bush on 1990. The number of accredit laboratories are 69 in Japan, 21 in Taiwan, 2 in Korea and 189 in U. S. A, as of 09/10/1998. The JAB accreditation encompasses the requirements of the ISO/IEC Guide 25, and the relevant requirements of ISO 9002. The purpose of ISO/IEC Guide 25, also had been harmonized as JIS Z 9325 'General requirements for the competence of calibration and testing laboratories 'mainly facilitates and promotes acceptance of calibration and test results between countries to avoid barriers to trade through as 'one stop testing'. The features and differences between Guide 25 and ISO 9000 will be clarify in this report.

  • This paper discusses an empirical study on extracting requirements for ubiquitous computing technology-based information system (ubi-IS) using factor analysis. After preliminary review of related literature, features specific to ubiquitous computing technology have been retrieved, selected in terms of main elements of information system (IS) (network, device, user interface, and operating system), and further used as variables during conducting factor analysis. Quantitative data was collected through questionnaire approach. The results of factor analysis manifested 5 factors containing 15 variables, and eventually, based upon the extracted factors the requirements for ubi-IS were identified.

  • Kano model distinguishes three types of customer requirements, namely, one-dimensional quality, must-be quality, and attractive quality. There are a few methods for classifying a given customer requirement into one of the Kano's quality elements. However, the existing methods have a common limitation in that they are based on Kano evaluation table. Kano evaluation table is not always effective for the classification task, and suffers from a significant information loss. This paper proposes an alternative to Kano's evaluation table and a new classification scheme based on fuzzy set concept. The proposed method is illustrated using a case study on the ADSL service.

  • Although some CASE tools supported conceptual data design, they required for users too much preliminary knowledge to learn how to use and handle them. In addition, in a number of studies on conceptual data design with natural language, they claimed passive participation for users with conforming to messages predefined by CASE tools. As an alternative to these traditional CASE tools, we proposed an ERD formulator for automated data design tool, called ERDF, so that even ordinary users, not necessarily data modeler, are capable of formulating ERD on business requirements by use of ERDF. We, first of all, introduced NSM as the standard methodology. We also designed the structure of ERDF including main controller, input controller, operation controller, regulation controller, schema controller, and output controller. We then defined conceptual domains and basic operations to lay down schema operations as well as sentence rules to handle input sentence in natural language. To get an ERD that is faithful to business requirements, we laid out supplementary design for dialogue and confirmation of soundness and completion.

  • IEC 62278 presents a process to implement a consistent approach to the management of reliability for railway applications. A reliability program has to be established at the outset of a project in order to manage reliability activities effectively through the life cycle. The first step of the reliability program is to evaluate reliability requirements and targets based on the system specifications. The system specifications are derived from the customer's needs. The way in which the system requirements reflect the customer's needs is strongly dependent on the characteristics of the product. In general the customer of commercial trains presents the system requirements from their needs. However, the relation between the customer and supplier is equivocal for a project to development a prototype train, and the reliability program should be different from that of an usual commercial project. This paper deals with a process to manage reliability activities for the development of a protype train based on the experiences obtained from the development of the Korea High-Speed Train: Hanvit-350.

  • This paper describes the method of establishing efficient system for the control of quality records. To establish the best control system of quality records, the organization must not only understand ISO Code requirements for quality record complectly but also identify the documents to be controlled as a quality records correctly. In addition, when establishing the system, the organization must absolutely consider the fact that quality records shall be maintained to demonstrate conformance to specified requirements and the effective operation of the quality system. This will provide the guidance which need to establish the system for quality control to the organization which produces documents in accordance with ISO Code requirements.

  • Common problems have been observed in the existing Information Requirements Analysis (IRA) methodologies such as BSP(IBM), CSF(Rockart), or ISP(Information Engineering), etc. These methodologies require too much time and human resources for the IRA process, involves high complexity, and their IRA outcomes are frequently biased by the subjective views of the people involved. In this paper, we introduce a new methodology for the enterprise wide information requirements analysis utilizing templates and nine closed-ended questions. Extending the BIAIT(Business Information Analysis and Integration Technique) method, this methodology presents nine question about each firm's order type(7Q's for customer side and 2Q's for supplier side) to derive information processing characteristics of the firms. As the central component of this methodology, data and process templates for the manufacturing industry were established. To validate the methodology, suitability of the data and process templates were examined through six real world business cases.

  • The purpose of this study is to reinforce employment improvement of engineering college students and the industry-university collaboration of regional industries. In order to achieve the object of this study, we inquire and analyze the general requirements for engineering college students and specific requirements for each major of engineering college. In addition, we survey and analyze the industry-university collaboration programs and awareness of them. When regional companies hire new workers affiliated engineering students, they significantly consider executive ability related to their majors and self-confidence. The education and research area by each department and the status and the intention of industry-university cooperation are also investigated. Eventually, we propose the education plan to meet the industrial requirements and industry-university cooperation strategy.
