In this paper, we propose the framework of an integrated design system as a CAD system of a new concept that can incorporate the design information. Current CAD systems are powerful in representing the shape of a product with solid models but cannot provide the design information that is used or created in designing the product. Therefore an integrated design system is proposed to enable the storage and usage of the design information in addition to the shape manipulation. In order to represent the design information, we define element object that represents design element such as a part, a sub-assembly or an assembly by using object-oriented methodology. The element object carries various design information such as design parameters, documents, catalogues, functions, and behaviors as well as shapes. By using the stored information, the system can provide a designer with some functions to assist design activity such as interrogating necessary information, setting design parameters and goals, and constructing constraints among design elements. A mailing system is also constructed among element objects to assist a collaborative design. In addition, an evolutionary design method using genetic algorithms is realized within the proposed framework.

To increase the productivity and efficiency of an enterprise, all relevant product information should be provided to shop floor workers timely and in a unified form because shop floor workers are final consumers of most accumulated information generated from various departments of an enterprise. But, most existing enterprise information systems have an emphasis upon providing design/manufacturing information to office workers. Proposed in this study is the development of integrated design/manufacturing information system focused on providing cohesive information required to shop floor activities. For developing integrated information system, the functional requirements at the shop floor are identified and analyzed. Based on the extracted functional requirements, object-oriented system design and implementation is conducted. By using this system, shop floor workers can use all relevant information required to their daily operation in a integrated and unified form.

Recently as users' requests for geographic information systems are being more various, several new functions are being added to existing geographic information systems. One of them is linkage of spatial geographic data and video / image data to offer more realistic information of geographic objects to users. Geographic information systems implementing this function are called video geographic information system. In this paper, we design and implement a video geographic information system for providing map data, video data and link information of them to web applications. We 1) design system architecture of a video geographic information system, 2) analyze some processes to construct link information of map data and video data, 3) design database schema to store map data, video data, and link information, and 4) design some XML/GML schema used to query and retrieve these data for web applications.

In this paper, a design process is established by integrating aviation safety requirements for the development of general aviation aircraft. An Airworthiness-Design Integration System, which integrates certification requirements with the entire design/analysis process, is developed and presented. For the proposed system, KAS 23/FAR 23/AC 23/CS 23 certification regulations are analyzed to determine design constraints and system compliance checks and to construct an ER&G (Engineering Requirement and Guide) and a Design-Certification Related Table (DCRT). Furthermore, through building a DB (Data Base), the management of design and certification related resources for developing a FAR 23 class aircraft are made. Certification tools and resources are also efficiently managed by the DB. The connection between the certification requirements and the detailed design process is proposed in this system. Tracking of this proposed method is validated by configuring a USE CASE and a system. The Airworthiness-Design Integration system will be constructed based on the system's design plan, certification system, and usage scenarios.

Effective design of a database is essential for operating application systems efficiently. This paper discusses database design for a geographic information system. This goals of database design are multiple: to satisfy the information content requirements of the specified users and applications; to provide a natural and easy-to-understand structuring of the information; and to support processing requirements and any performance objectives such as response time, processing time, and storage space. Database design is a very complex process and is decomposed in three phases: conceptual, logical, and physical design. In this paper, we first collect and analyze the requirements for a geographic information system. We also perform database design for these requirements through the three design phases systematically. Our results would contribute to the effective construction of a database for a geographic information system.

This paper introduces a method of constructing expert systems in an integrated environment for automatic software design. This integrated environment may be applicable from top-level system architecture design, data flow diagram design down to flow chart and coding. The system is integrated with three CASE tools, FSD (Functional Structure Diagram), DFD (Data Flow Diagram) and structured chart PAD (Problem Analysis Diagram), and respective expert systems with automatic design capability by reusing past design. The construction way of these expert systems is based on systematic acquisition of design knowledge stemmed from a systematic design work process of well-matured developers. The design knowledge is automatically acquired from respective documents and stored in the respective knowledge bases. By reusing it, a similar software system may be designed automatically. In order to develop these expert systems in a short period, these design knowledge is expressed by the unified frame structure, functions of th expert system units are partitioned mono-functions and then standardized components. As a result, the design cost of an expert system can be reduced to standard work procedures. Another feature of this paper is to introduce the integrated environment for automatic software design. This system features an essentially zero start-up cost for automatic design resulting in substantial saving of design man-hours in the resulting in substantial saving of design man-hours in the design life cycle, and the expected increase in software productivity after enough design experiences are accumulated.

This paper describes an architecture information management system using XML. The purpose of the system is to manage the information stored in standard format, XML, that has many valuable properties. The proposed architecture information consists of project information, drawing information, and material information. Each information is expressed using XML and for each information, XML schema is presented in this paper. In this system, detail information of materials that exists on the supplier's homepage can be displayed when the user of the system wants to check the detail information. Also, drawings stored in STEP data can be browsed in this system. The reports of each information are prepared using XSL. The proposed system shows that XML can be used for a format to store architecture information and various functions can be implemented based on XML related standards.
