This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.

Nuritkum Square Project is a IT Complex which is being constructed in Digital Media City. The project consists of several buildings and is a Design-build, so that the systematic construction management from design to construction stage is more important for a successful project. This study introduces the practical tasks of construction management during the project and analyze some of main tasks to increase understanding construction management in the design-build project. Based on experience of construction management in this project, we examine managerial problems which frequently occur in this kind of project, and suggest how to improve construction management in Korea.

This paper suggests the design and operation of value stream mapping(VSM) applied to project management, such as R&D, IT Investment. First this study represents design methodology of VSM process using SIPOC(Supplier, Input, Process, Output, Costumer). Second, this paper considers the identification and improvement plan about non-added value time for VSM using FPC(Flow Process Chart) and PERT/CPM. Last, this paper proposes VSM scheduling method using PERT/CPM and CCPM(Critical Chain Project Management)

Collaborative product commerce(CPC) involves many people working together with heterogeneous and distributed software applications. For such an environment, Workflow Management System(WFMS) can be useful for coordination of people, software agents and processes. It provides diverse services including automatic work muting, project management continuous process improvement and application integration. However, there are some limitations to apply WFMS to CPC environment due to inflexibility and lack of design support facilities. This paper identifies the problems and addresses possible approaches to overcome the difficulties.

Construction Projects have mutual collaborative structures among various participants for common objectives. Most of all the design project which is the initial phase in the project is crucial for determining project overall quality and requires intimate and continuous relations between project participants. Thus, this study suggests Design Collaboration Management System for successful performing projects through cooperation among participants in the initial stage of projects. First, expert interviews were performed to figure out present conditions of design collaboration management and problems. The factor analysis was applied to draw owner's collaboration factors and engineer's collaboration factors. Based on those factors, this study suggests design cooperation management process which gives a framework for systematic management method. Through the process the design collaboration management system was developed which helps owner/designers/engineer's co-work. The System suggested from this study realizes systematic information management tool and through that it is expected to improve design product;'s quality, and further contribute the advancement of project.

In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.

This paper considers robust design strategies for off-line quality control, with the use of experimental design and response surface methodology, in situations where all products have multiple quality characteristics. These strategies can be developed using the desirability concept of desirability functions to determine the settings of the design factors, not only to get the average performances on target but also to minimize variability around the target values.

This is a report on a new methodology to manage design knowledge by utilizing a knowledge-based CAD and a prototype system named $C^3$ (Cubic; CAD knowledge Code Capacitor), which is being developed using our methodology. $C^3$ facilitates (i) the automatic generation of a knowledge code for a knowledge-based CAD by processing design documents written in the format near the natural language, such as English or Japanese, and (ii) automatically generation of a design document written in the format near the natural language from the knowledge code. The features of the system facilitate document-based design knowledge management which reduces the designer's load to encode and maintain design knowledge, because it is easier for a designer to treat a natural language description than a coded description.

This paper considers the design and management of security MIB for EDI system. EDI system has to establish various securety wervices and mechanisms to protect against security threats. Hence, the EDIsystem requires appropriate security management to monitor and control the security obhects for its security services and mechanisms. In this paper, I identify security objects for management of secueity services defined in the EDIsystem, and propose the design of a security MIB and describe the use of SNMPnetwork management protocol in its management.
