Quality function deployment (QFD) is a widely adopted customer-oriented product development methodology by translating customer requirements (CRs) into technical attributes (TAs), and subsequently into parts characteristics, process plans, and manufacturing operations. A main activity in QFD planning process is the determination of the target levels of TAs of a product so as to achieve a high level of customer satisfaction using the data or information included in the houses of quality (HoQ). Gathering the information or data for a HoQ may involve various inputs in the form of linguistic data which are inherently vague, or human perception, judgement and evaluation for the information and data. This research focuses on how to deal with this kind of impreciseness in QFD optimization. In this paper, it is assumed as more realistic situation that the values of TAs are taken as discrete, which means each TA has a few alternatives, as well as the customer satisfaction level acquired by each alternative of TAs and related cost are determined based on subjective or imprecise information and/or data. To handle these imprecise information and/or data, an approach using some basic definitions of fuzzy sets and the signed distance method for ranking fuzzy numbers is proposed. An example of a washing machine under two-segment market is provided for illustrating the proposed approach, and in this example, the difference between the optimal solution from the fuzzy model and that from the crisp model is compared as well as the advantage of using the fuzzy model is drawn.

최근 거의 모든 산업에 걸쳐 보안과 서비스에 대한 이슈가 대두되고 있다. 이는 항만물류산업에서도 큰 영향을 미쳐 기존 항만 생산성 향상에만 초점을 두어 업무를 추진하던 방식에서 탈피하여 점차 항만 안전과 대고객 서비스 향상을 중심으로 업무 전환을 꾀하고 있다. 그 중 대표적인 방법이 기존의 컨테이너에 특정한 장치를 추가 장착하여 지능화시킨 GE(General Electronic)의 CSD(Container Security Device)와 Savi Networks의 eSeal 등을 들 수 있다. 하지만 이 장비들은 국제표준과 기술적인 구현 부분에만 치중하여 개발함으로써 화주, 선사 및 하역업체 등 실 사용자들의 불편함을 야기하고 있으며 이는 사용자 요구사항을 체계적으로 충분히 고려하지 못한 결과로 판단된다. 본 연구에서는 기 개발된 보안 장치가 갖는 문제점들을 해결하고, 사용자 요구사항이 충실히 반영되었을 뿐만 아니라 현실세계를 고려한 보안 시스템을 개발하기 위해 시스템 요구사항을 도출하는 과정에서 QFD(Quality Function Deployment 품질 기능전개) 방법론을 적용하였으며 그 결과 시스템 품질특성(CTQ: Critical To Quality)이 5가지의 세부 과제별로 총 21건이 도출되었다.

Purpose - The purpose of this study is to analyze the user requirements and developer requirements in virtual reality(VR), and suggest ways to increase the satisfaction of users who experience virtual reality. Specifically, focused on experience store of VR as a distribution retailer, user requirements were analyzed according to the results of previous research that the characteristics of Affordance, Presence, and Head Mounted Display (HMD) affect user satisfaction. Research, design, data, and methodology - Based on previous studies, in this study, we analyzed the importance of immerse, interaction, perception, and presence for the satisfaction of the user through the questionnaire, and the user experiences virtual reality (VR) The importance of HMD, Presence, Affordance, and experience satisfaction were analyzed. Based on this, we analyzed the user requirements and the developer requirements based on the questionnaires and interviews of the experts, starting from the user's desire or preference using QFD technique. Results - As a result of the analysis, the development factors that occupied a big part in the virtual reality field appeared to be visual. In detail, this showed that there was a lack of sense of presence for users. This should be improved. This paper shows that the requirements for visual, auditory, and tactile development are necessary. For the satisfaction of the users of virtual reality (VR) users, it is necessary to develop them according to their priority in consideration of importance and difficulty in the future. Conclusions - In this study, it was suggested that development according to priority should be considered, considering the difficulty level. Based on the results of this study, the following suggestions are made. First, we tried to search the list of user requirements as much as possible, but it is likely to change due to the development of VR technology. Therefore, it is necessary for developers to continually supplement user requirements with recent research literature. Second, development priorities according to difficulty level should be considered. This aspect should be considered in the actual VR development process, so if the numerical value of the difficulty is calculated, it should be presented in the research.
