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.

This paper presents an integrated but open product development environment for distributed and collaborative design. The web-based framework, called DOME, allows designers to build integrated models using both local and distributed resources, and to collaborate by exchanging services in a network-centric product development environment. Thus, an integrated model can be created while each participant focuses on his or her own area of expertise. A design problem model is created by connecting modules, which represent specific system components, analysis capabilities/software, disciplines, or organizations relevant to the problem. The modules interact with each other using service exchanges based upon the CORBA standard communication protocol. The goal of this framework is tall provide the ability to rapidly construct integrated design problem models to facilitate collaborative design work, improve product quality and reduce development time. Ultimately, it should allow specialized engineering applications and design problem models to operate under a common design environment.

A telecooperation system supports synchronous cooperation among all the product development partners and enables compensation of deficits concerning traditional information/communication technologies. By analyzing the product development processes and communication scenarios of a company manufacturing automobile parts, the specifications for the suitable telecooperation system were defined. An integrated telecooperation platform that combines the commercial softwares with the new developed modules for customer-oriented functionalities was created as a product development guideline. Future work is strongly required in order to define the best way to improve the integrated platform, based on the functionality of ERP and PDM systems.

Since software and hardware integration has became a strategic tool for companies to innovate their products, an information system that can comprehensively manage software and hardware integrated product development is critical for the current product development. This paper proposed a product data model that can support modules of related software and hardware parts in Product Data Management(PDM) integrated with Software Configuration Management(SCM). The model allows engineers to define software and hardware product structure independently, and support the integration module that can summon related software and hardware parts to build a comprehensive module for collaboration. Through the integration module, engineers can identify and examine the effectiveness of their design alternatives to other related parts form different disciplines. The product data model was implemented as a prototype PDM system and tested with an example robotics product.

The terminology such as ecology, environment problems, ecosystems, ecofactory, and others related to environmental problems have been recently used in manufacturing systems, since the modern industries have to consider a global ecological crisis. The indifference of recent environmental problems which may be faced now has been paid attention to all engineering areas. In this paper, manufacturing functional requirements such as disassembly, disposal, disposal, or recycling are considered in the integrated product design development, which have not been considered well in the preliminary design stage. Those functions will contribute to reduce the waste and to long the product life cycle, which also satisfies the business benefits and customer requirements. The concurrent design concepts should be applied to integrate all possible factors. Therefore, few practical concurrent engineering tools are presented in here. The objective of this paper is to develop a called green manufacturing systems for integrated product design development by concurrent design concept which can give the desirable result in product design.

In today's engineering world, any product development activity requires the expertise and the interaction of many different engineering. Therefore the various activities in a product development architecture are highly distributed and interdependent. The interdependence may be due to sharing of databases and transfer of information between various activities. This will require an integrated product model. That can support distributed design such that participants from different backgrounds collaborate towards one common goal. This paper presents the architecture of the product modeling system for the integration of CAD and CAE. It then reports on the study of STEP 10303 and UG open API focused on the integration of different technical environments.

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.

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.
