A product family design has received much attention over the last several decades, since a product family-based development shortens lead-times and reduces cost, as well as increases efficiency and effectiveness of the product realization process. It is challenging work, however, to define the product family design in the heterogeneous product development environments, due to myriads of products related information described in different ways across products in any companies. In this paper, we provided a way of defining product family design framework using formal concept analysis and ontology language. Based on this, the specific product family can be derived by ontological reasoning, and the new product concept can be also expanded in the framework. The proposed framework is formalized using OWL (Web Ontology Language) and implemented in $Prot{\acute{e}}g{\acute{e}}$. Actual product family design algorithm is carried out using FaCT++ engine, a plug-in to $Prot{\acute{e}}g{\acute{e}}$, and the benefits of the proposed method are also demonstrated through a case study.

New product concept evaluation is one of the most important activities among many possible evaluation activities involved in the whole new product process. This paper aims at exploring the applicability of the Analytic Hierarchy Process(AHP) to this new product concept evaluation. To this aim, an AHP based concept evaluation model was formulated and explained using an illustrative example. A number of issues were also raised and discussed concerning the applicability of AHP to out problem. Finally, some further research areas were identified.

Increasing product variety based on product family and product platform provides a company with a competitive advantage over its competitors. As products become more complex, short-life cycled and customized, the design efforts require more knowledge-intensive, collaborative and coordinating efforts for information sharing. By sharing knowledge, information, component and process across different families of products, the product realization process will be more efficient, cost-effective and quick-responsive. Formal Concept Analysis (FCA) is used for analyzing data and forming semantic structures that are formal abstractions of concepts of human thoughts. A Web Ontology Language (OWL) is designed for applications that need to process the content of information instead of simply presenting information to humans. OWL also captures the evolution of different components of the product family. The purpose of this paper is to develop product variety modeling to increase the usefulness of common platform. In constructing and analyzing product ontology, FCA is adopted for conceptual knowledge processing. For the selected product family, product variety Ontology is constructed and implemented using prot$\'{e}$g$\'{e}$-2000.

This study investigated the type of fashion brand concepts and derived the components of fashion brand concepts. A total of 125 brand concept texts of women's wear brands were collected from "2012/2013 Korea Fashion Brand Annual" (S. M. Kim, 2012). A qualitative research method was employed. To investigate the types of fashion brand concepts, the texts were classified into three types such as functional, symbolic, and experiential concepts, and four complex types such as functional/symbolic, functional/experiential, symbolic/experiential, and functional/symbolic/experiential concepts. Open coding and axial coding provided the components of fashion brand concepts. The results were as follows. First, an investigation of the types of fashion brand concepts indicated differences in the types of fashion brand concepts and the types of general product brand concepts. One content of a fashion brand concept could be interpreted as more than two concept types; consequently, many fashion brand concepts did not fit the notion of the types of general product brand concept. Most fashion brand concepts simultaneously encompassed more than two types of brand concepts at once. Second, the components of fashion brand concepts consisted of 55 subjects, 7 sub-categories (physical/intrinsic product characteristics, symbolic/conceptual product characteristics, target demographics, target consumer behavior, brand capability, brand values, and brand management/marketing) and 3 categories (product, target consumer, and brand).

신제품개발 프로세스에서 컨셉테스팅은 신제품개발을 위해 산출된 아이디어들 중 가장 높은 시장 성공 가능성을 갖는 아이디어를 스크린하는 것으로 신제품의 성공을 예측하는데 아주 효과적이다. 그러나 실제적으로 컨셉테스팅에서 가장 중요한 부분인 소비자 선호에 대한 인과 구조가 정량적 데이터로 제공되지 못함으로써 디자이너들이 신제품을 개발하는데 있어서 정확한 가이드라인을 제공받지 못하고 있다. 따라서 본 연구는 컨셉테스트에 그러한 문제를 해결하는데 도움이 줄 수 있는 수단-목표 사슬이론과 제품 형태이론을 적용하여 소비자들이 선호하는 제품은 어떤 혜택을 내포하는지 그리고 그 혜택은 어떤 디자인 속성이 충족시키는지에 대한 구조를 제공하여 신제품 컨셉 개발에 대한 지침을 제공하는데 목적이 있다. 이를 위하여 수단-목표 사슬이론과 제품 형태이론에 대해 고찰하고 연구모델을 구축한 다음, 실증연구를 통하여 해당 카테고리제품(TV의 컨셉 개발에 대한 지침을 제공한다.

본 연구에서는 지문인식 도어락제품의 특징에 대해 살펴보고, 디자인 컨셉을 결정짓는 체계적인 방법론에 대해 알아본다. 디자인 개발 프로세스는 제품의 종류와 그 특성에 따라 많은 단계를 거치게 된다. 특히 개발 초기의 컨셉을 선택하는 단계는 시장에서의 성패를 좌우하는 매우 중요한 시기이다. 본 연구에서는 다소 주관적이고, 비논리적 일 수 있는 컨셉 선택과정을 보다 객관적이고, 체계적 인 프로세스로 정립할 수 있는 방법론을 모색한다. 컨셉 선택 프로세스는 크게 두 가지 단계로 나누어진다. 우선, 컨셉을 결정짓는 요소들을 매트릭스로 구조화하여 많은 대안이 제시되었을 때보다 신속하고 합리적으로 대안을 선별해 나가는 과정이 있다. 다음으로는 선택에 영향을 주는 요소들에 가중치를 적용하여 평가함으로써 보다 이상적인 컨셉을 선택해가는 과정이 있다. 선택된 컨셉을 구체화하여 양산을 위한 디자인 확정안에 대한 렌더링을 결과로써 제시한다.

This study aimed to examine the theoretical consideration and concept of hybrid that could be applicable to wood product design, to analyze design trend according to the morphological transformation by means of combination of hybrid material and function, to understand the correlation between type of wood product and materials and to apply it to the domestic and overseas hybrid concept of wood product design study. A study of assembling output by empirical experiment to embed natural resources into acrylic resin in order to develop wood products was carried out. And an wood product was suggested that satisfied lighting and hanger function through a new wood product design development combined with hanger function and lighting function. Through such process, a new design paradigm was suggested to cope with the periodic trend and to induce mass production of designed product. Thus, this study set a new guideline for activating wood product design and attempted to meet the social demand of encouraging new value creation.

This paper describes a comprehensive approach to examine how technological innovation contributes to the renewal of the firm's competences through its dynamic and reciprocal relationship with R&D and product commercialization. Three theories of technology and innovation (R&D and technological knowledge concept, product-process concept, technological interdependence concept) are used to relate technology and innovation to strategic management. Based on those theories, this paper attempts to identify dynamic relationship between product innovation and process innovation by system dynamics, by investigating the aspect of the dynamic changes of the closed feedback circulation structure in which R&D investments drive technological knowledge accumulation, and such knowledge accumulation actualizes product innovation and process innovation, subsequently resulting in the increase of productivity, customer satisfaction, profit generation, and re-investment on R&D from the created profits. This provides the ability to assess the advantages and disadvantages of different technological innovation strategies and commitments, and the opportunity to explore equilibrium point and suggest a generalized technological innovation model under different industry environment parameters and time-strategies.
