The current market preassure of least environmental effects of products needs companies to consider whole life cycle of their products during their design phase. To support the integrated and collaborative development of the products, this paper proposed product data model for extended Product Data Managemen (PDM) that can support integrated design of product, manufacturing process, and customer services, based on the consistent and comprehensive PDM databases. The product data model enables design, manufacturing, and service engineers to express their products and services efficiently, with sharing consistent product data, engineering changes, and both economical and environmental evaluations on their design alternatives. The product data model was implemented with a prototype PDM system, and validated through an example product. The result shows that the PDM based on the proposed product data model can support the integrated design for products, manufacturing process, and customer services, and provide an environment of collaborative product development for design, manufacturing and service engineers.

본 논문에서는 통합제품개발 관점에서 Computer-Aided Engineering(CAE) 활동을 지원하는 제품자료모델(Product Data Model)을 제안한다. 제안된 제품자료모델은 제품개발 프로세스를 관리하는 제품생애주기관리(Product Lifecycle Management: PLM) 시스템에 현재 독립되어 진행되고 있는 CAE 활동을 통합될 수 있도록 한다. 제안된 제품자료모델에 포함된 제품관점(Product View)은 설계와 제품구조를 공유하여 다양한 대안을 해석하고, 그 결과를 손쉽게 설계로 전달할 수 있는 독립적 CAE 활동을 보장한다. 제안된 모델을 검증하기 위하여 제품개발 프로세스와 통합된 CAE 활동을 지원하는 PLM 시제품을 개발하였다.

In this paper, we have proposed an integrated aircraft development environment which can support virtual design and development for Systems Engineering and IPPD(Integrated Product and Process Development). We have also proposed the ViMS(Virtual Mockup System) which can perform a system design review on an integrated aircraft development environment. The ViMS is an integrated virtual design support system with immersive design review functionality to make a virtual mockup instead of a physical mockup through the virtual reality technology. The functionality of the ViMS consists design data management, design technology, design verification, and design assessment. We have described the detailed development artifact, case studies and conclusions of using the ViMS functionality.

The purpose of this paper is to study user's involvement in new product development (NPD). It seeks to identify the factors involving user and design practices in the design process of new product development. A survey was conducted on 20 respondents consisting of designers involved in product development from various industries. The study focused on the early activities of the product design process which is called product specification. The analysis performed considers the importance of involving users in design decision. The outcome of this research is the significance of involving users and its effect on product development activities. The research also provides a model for an integrated user, designer and product knowledge activity in the product development process.

Today's product development requires simultaneous satisfaction of low cost, high quality and fast time to market. It is, however, difficult for product designers and engineers to achieve this goal due to too many requirements. This study shows integrated Computer Aided Engineering (CAE) approach can help to achieve such goal. CAE can not only support designers when decision needs to be made during concept design period but also provide evaluation of the designed parts and guidance to the best design of products during detail design period. Furthermore, integration with virtual prototyping concept can reduce number of actual prototyping and consequently reduce product development cost and time considerably. In order to demonstrate its possibility, example of washing machine development using CAE and its results are presented in this study.

현재 기업에서는 제품인증과 경영시스템인증의 신뢰성 확보가 중요한 과제이다. 이는 제품개발 중심에서 제품 및 프로세스의 통합 개발 중심으로 연구의 필요성을 제시 해주고 있다. 따라서, 정적인 제품인증에서 동적인 시스템인증의 필요성이 대두되면서 신뢰성경영시스템(DMS; Dependability Management System; IEC60300)이 요구되어진다. 제품개발의 프로세스에서 발생되는 신뢰성 문제점들을 해결하기 위하여 트리즈(TRIZ ; Theory of Inventive Problem Solving) 기법을 활용하였다. 본 연구에서는 창의적 문제해결 방법론인 트리즈기법을 활용하여 신뢰성경영시스템에서 제품 및 프로세스 통합개발(IPPD; Integrated Product and Process Development)을 하고자 한다. 결과적으로 창의적 신뢰성경영시스템(CDMS; Creative Dependability Management System)을 제품 및 프로세스 통합개발 모델로 제시한다.

This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

Concurrent Engineering(CE) can provide a competitive edge for companies that have confronted with rapidly changing market requirements, such as shortening of product life cycles, high quality, low cost, diversity of customer demand, and so on. We construct a prototype of integrated information system to support a new product development process by CE concept. This integrated information system can be useful for considering concurrently all of the aspect in the product design process. In this system, an Engineering Database is constructed for gathering data of four departments; i.e. marketing, production, quality control and design department. Also DFM(Design For Manufacturability) is applied for analysis of product design.

New product development is a complex managerial process which involves multiple functional groups, each with a different perspective. Quality function deployment (QFD) is a new product development process which stresses cross-functional integration. QFD provides a specific approach for ensuring quality through each stage of the product development and production process. This paper provides an overview of QFD including its concepts and methods, and then proposes an integrated approach to formulating and solving the QFD process. This paper also discusses issues associated with the prescriptive modeling of QFD.

Concurrent Engineering is one of the methods which are used for the rapid product development. One of the important features in Concurrent Egineering is that the development process is to be parallel and the organization should be cross-functional. In order that the process be parallel and that the organization be cross-functional, an integrated information system such as PDM (Product Data Management) is required. Although the integrated data base is constructed, it could be meaningless if the application softwares were not inter-operable. This study shows an example of intergrated information system from three-dimensional product design to mold design and tooling for the development of Deflection Yoke(DY) which is one of the important parts of Cathode Ray Tube(CRT). A three-dimensional product design software, which is based on a commercial code, has been developed by ourselves. Selective Laser Sintering(SLS), which is one of the rapid prototyping techniques, has been used in this study. Mold design has been done by the three-dimensional way. A newly developed method of mold tooling, which is called Quick Die Manufacturing(QDM), has been introduced.
