The corporate R&D(Research and Development) has a primary role of new product development and its potential is the most crucial factor to estimate corporate future value. However, its systemic inadequacies and inefficiencies, the shorten product life-cycle to satisfy customer needs, the global operations by outsourcing strategy, and the reduction of product cost, are starting to expose to R&D business processes. The three-phased execution strategy for R&D innovation is introduced to establish master plan for new R&D model. From information technology point of view, PLM(Product Life-cycle Management) is one of the business total solutions in product development area. It is not a system, but the strategic business approach that collaboratively manage the product from beginning stage to end of life in all business areas PLM functions and capabilities are usually used as references to re-design new R&D process. BPA(Business Process Assessment) and 5DP(Design Parameters) in PI6sigma developed by Samsung SDS Consulting division are introduced to establish R&D master plan and re-design process respectively. This research provides a case study for R&D process innovation. How process assessment and PMM(Process Maturity Model) can be applied in business processes, and also it explains process re-design by 5DP method.

This paper proposes a product data model and associated process for CAE activities in context of integrated product development. The data model and process enable Product Lifecycle Management(PLM) systems to integrate currently separated CAE activities into the main product development process. The product view concept in the proposed product data model supports independent CAE activities including analysis of various alternatives based on shared product structures with design departments and seamless translation of the CAE result to design product views. The proposed model is validated through an implementation of a prototype PLM system that can integrate and synchronize CAE process with the company-wide product development process.

The Processes of a new product design based on ergonomics and customer satisfaction have been studied for years. However, few attempts have been made to systematically include ergonomic design concept to communication service design. Service design can be regarded as a specific type of product design in a way that the processes of product design can also be employed to those of service design. However, a few difficulties may often arise in doing so. First, services have no explicit tangible features, which implies that a customer may not properly appraise contents, quality and functionality of newly designed services with a prototype before launching into market. Second, customer demands on services change more rapidly according to advances in related technology. In the study, we examined earlier studies of product design process and identified that a service design process must alos conform ergonomic methodology, extracting innovative values for creativitybased design and subsequently evaluate its level of customer satisfaction. In this study, we proposed a customer-centered ergonomic design process for communication services. This process includes a hierarchical structure of service requirement identification, customer-centered trend analysis, service scenario development and service evaluation. To prove the practicality of the design process, a case study of communication service design was conducted according to the procedure that follows.

This paper describes an image design process for product development based on human sensibility ergonomics.. The human sensibility about product image can be measured through some statistical methods and translated into product design factors by some mathematical inference logics. This results also can be presented by 3D computer graphic tools, In order to integrate the above processess, a image design process on human sensibility database. Human sensibility database is constructed with the relational ddta of some adjective words and design factors, The next step is to extract the design information from the human sensibility dataabase by fuzzy inference algouithm. This information is used for the input data for the graphic presentation. The final product can be modified according to the customer's requirement.

When a product is designed, user's requirements should be well analyzed and applied to the design so that the psychological and aesthetic factors of a product can be accurately conveyed to consumers. The essence of product development is to analyze the changes in the purchasing tendency of consumers and the needs of times, find out user experiences to apply to a design, and establish the objective of product development that well considers those. Designing should be recognized as one that designs even the sensitivity and experience created in the relationship with users, beyond the conventional notion of design that it draws the physical form of a product. As the subjects that design should consider have expanded like this, it has become important that today's design provides a new experience as well as simply develops formative elements based on the functions of an object. As a result, it becomes impossible to accomplish such objective only with the traditional design process that existing designers have stuck to so far. In this respect, this study is aimed to draw out a system and methodology for a user-oriented design process so that design can provide expanded experience to users from product form, applied material, and service.

An expert system is a system that employs human knowledge captured in a computer to solve problem that ordinarily require human expertise. Well-designed expert systems imitate the reasoning processes experts use to solve specific problem. Specially, expert systems are used to the engineer in manufacturing industry for the process control, production management and system management. In this paper, we propose the design process expert system for product design process in manufacturing industry and we present introduction and contents of design process expert system methodology and software for the air purifier design system. This system will be helpful to improvement of design process for the air purifier production.

At the product design and development stage, the main criteria selecting a design alternative were performance aspect as well as cost aspect of a product. Ongoing new paradigm shifts such as low carbon green growth, climate change mitigation, sustainable society development urged considering environmental aspect of a product at the product design and development stage. Up to recently, only cost aspect except performance of a product was considered at the railway vehicle design process. Therefore, it is needed to develop a method that may consider environmental aspect of a product at the railway vehicle design process. Lee (2011) proposed that a method of an integration assessment of environmental aspect and cost aspect based on GHG emission instead of based on monetary value. This study conducted that apply the method of Lee (2011) to design alternative selection process of a railway vehicle. From the integrated view of environmental and cost aspect, the reference product and design alternatives are assessed and compared.

The goal of this study is leading discussion on emotional design focused on product domain and approaching it through a practical way so that it'll be able to help designers in their real design work when they design products in an emotional way. Discussions on emotions are remaining on abstract levels and only focusing on 5 senses even though the importance of emotions are increased. But much more is needed to apply emotions in the product domain because these are not the proper forms for applications and they only cover limited parts of it. Therefore, in this study we proposed the notion of 'Emotionalized Product' and defined it into a practical level. We extracted 5 useful frameworks of 'Emotionalized Product(EP)' as a results; EP Media, EP Procedure, EP Level, EP Character, and EP Value. Then we clarified EP with these frameworks. After that, we extracted 2 frameworks: Domain Structure, and EP Opportunity, to combine EP with a real product. Finally we proposed the EP Design Process consisted of Inductive and Deductive Process based on previous work. It can be shared by designers as a base of designing system, and it also can be helpful to design products more successfully with an emotional approach.

The aims of the study are first, in other to meet the demand for a new product design process, to review the prototype theory and to find out the conceptual structure of product aesthetics, which is another properly thought to be as important as the typical pattern in an effort to patch up the theory second to help designers overcome the limits of idea generation and create consumer oriented designs with a high success rate by setting up a new product design process that is established through the application of the aesthetically influential factor 'proportion'based on the preceeding studies that tested product aesthetics measuring devices. In other words, this study tries to find out product categories, making use of the prototype theory to introduce an ideal proportion for product design, recognizing the importance of proportion by conducting product pattern analysis: to create a differentiated method that can product consumer oriented designs, even if it only manipulate proportion and to establish a new design process that can systematically explain the methodology for various form generation that applies proportion. This study reviews the theoretical aspects of concepts pertaining to the above … and, based on them, empirically tests them by patting to use the programs, for proportion manipulation. This study was conducted in the following way: To begin with, this study takes out proportion out of some aesthetically influential factors that has a great impact on the way consumers prefer certain product designs and tries to see how proportion affects the consumer preference when consumers select a product. In addition, we could analyze the difference between the ideal proportion that consumers prefer and the traditional golden proportion produced through theoretical studies. The correlations between preferred proportion and ideal proportion, and preferred proportion and golden proportion could be shown. In order that we may create form variations through more detailed proportion manipulation on the basis of the ideal proportion verified as preferable, we again applied the proportion factor to the process utilizing PDS(proportion Distortion System). In the way the restraint of form generation could be pursued. All in all, this study makes an attempt to set up a design process to create new product forms through the application of Proportion.
