The objective of this study was to establish a procedure of concurrent engineering which can be easily a, pp.icable in Korean industry. An investigation of various techniques of concurrent engineering was conducted. Problems of Korean companies which can be resolved by concurrent engineering techniques were identified. Techniques which can resolve these problems at the relatively low cost and without complicated computer facilities were selected and form a procedure for this study. The procedure was a, pp.ied to a manufacturing company for validation. It was found that this procedure can substantially reduce time and cost of R&D and manufacturing.

The design development, and production of a product is one of the greatest challenges which flexible manufacturing systems face today. No matter how a company refines and controls the manufacturing process, if the product is not properly designed, it will not operate correctly or performed well. Therefore the focus on quality of design must be balanced. One such strategy certain to address the managerial and manufacturing of the future is concurrent engineering. Concurrent engineering calls for the consideration and inclusion of product design attributes satisfying all the design constraints such as customer requirements. Furthermore, concurrent engineering has been recently promoted in many industries as a response to competitive marketing pressures. Viewed as a systematic approach of creating high quality products and bringing them to market at lower cost and in significantly less time, it also attracts the attention of quality designers. In this paperm a methodology and model for optimizing the product design, especially selection of optimal design alternative, is developed. The focus of this paper is on product design as the most critical activity of concurrent engineering. The model is based on the customer requirements for quality. Customer requirements for a certain product can be grouped based on the various design attributes. The design attributes have the priorities. The number of design functions. Design attributes value are calculated, however these values are applied to the optimization method. Numerical example will be illustrated.

Continuous quality improvement is now the focus of research and application in quality engineering. To achieve continuous improvement, it's necessary to integrate quality tools and to plan, design and control the whole process of creating quality. Based on the extensive literature review and the philosophy of concurrent quality engineering, the paper analyzes the relationships among major quality tools such as QFD, FMEA, DOE and SPC and presents a basic model and structure for the integration of quality tools.

Recently, industrial environments have been drastically changed. Customers require cheaper, better, stronger products more than ever. Thus companies have to satisfy the requirements of customers to be survived in this kind of industrial environments. To cope with these requirements from customers, engineers in industries must accept new paradigm and use some special tools for developing new product. This study has applied a Concurrent Engineering which would be good for shortening of product development period in developing of Full Logic Deck mechanism using in car audio. In this paper, a real case of systematic approach and successful story of Concurrent Engineering application in developing Full Logic Deck mechanism is illustrated.

To survive in the intensive world wide automotive market, more and more automotive companies are investing their resources into concurrent engineering systems (CE) based on the combined CAD/CAM/CAE/ PDM technology. The main objectives of CE in automotive companies are the quality improvement of products and the reduction of cost and time to market. Remarkable effects are appearing from some of these companies. As shown in this paper, these successful automotive companies have been focusing on establishing the new process and methodology in applying CE into their car development process.

This study describes process and method to establish concurrent and/or sequential schedule planning for the system design process of the EIA632 standard. For this purpose, the study suggest Process and method that are context analysis of standard process, interface definition from activity decomposition, integration of related activities, and definition of concurrent and/or sequential work flow. The proposed process and method will contribute to minimize time loss that is emerged from activities iteration.

With the rapid development of nowadays technologies, the environment of product development is experiencing structural changes than ever. Manufacturers are put under never-experienced pressures to launch their products in the market both faster and less expensively than their competitors while continuously improving product quality These pressures have given birth to so-called, Concurrent Engineering which is a systematic approach to the integrated, concurrent design of products and their related processes, including manufacture and support. Most manufactiring companies now recognize the importance of concurrent engineering and put heavy emphasis on the research and impementation of concurrent engineering. However, with this fundamental change in the process of product development, designers rarely pay attention to this newly demanding process. Designers still stay in the middle of process, satisfying their roles in dealing with aesthetic points of product. Designers badly need to incorporate the concept of concurrent engineering to design to design process and to adapt to this new environment. With these backgrounds, the study sets the objective to understand the nature of concurrent engineering and explore the possibility of it's application to industrial design. Particularly this study focuses on how the concept of concurrent engineering can be applied from the stage of form development to prototyping. At first, background, objectives, and scope of the study are discussed as an introductory part. It is followed by reviewing theories of concurrent engineering such as definition, history, technologies, examples, state of art and so on. Subsequently industrial design is viewed in terms of concurrent engineering and problems in industrial design are identified. Base on the findinss of precedent part of study, new process of industrial design incorporating concurrent engineering is developed. For the demonstration of new process, a case study of design of palm-top printer is introduced. Case study shows how the sketch, and forms can be transformed into prototyping with the simultaneous cooperation with engineering and other related specialists. Finally the study in summarized and future studies are prospected.
