Today, due to the global recession car sales have been decreased rapidly and auto makers are competing continuously to expand their market share. Automakers are struggling in order to secure competitive cost and quality through continuous cost reduction and quality innovation activities to win in the competition. In this situation, auto parts makers are trying to reinforce price competitiveness by reducing COPQ (Cost Of Poor Quality) in the mass production stages by securing the quality of components in advance from the design stage through DFSS (Design For Six Sigma) activities which is 6 sigma approach in the R&D field. However, auto parts makers have been undergone various confusion, feeling difficulties to get interrelationship among various activities. Thus, this study is going to suggest approach method for much more effective R&D activities by securing interrelationship between ISO/TS 16949 system established in the auto parts industry and DFSS activities.

중국은 2004년부터 자동차 공업 관련 신산업 정책을 추진하기 시작하였다. 이와 함께 기존의 맹목적인 외자유치에서 높은 기술수준을 지닌 외자기업을 유치하는 방향으로 선회하였다. 이러한 정책적 환경 변화는 수많은 다국적 기업들 및 협력기업들의 중국 진출을 본격화시켰으며, 한국의 완성차 및 부품기업 또한 진출이 이루어졌다. 외자기업의 착근과정에서 나타난 제도적 변화에 의한 혁신적인 기술 적용 필요성은 기업의 기술 혁신 필요성과 조응하였는데, 효율적 공간 전략이 요구되었다. 첫째, 제도적 변화에 따른 로컬 파트너십 활용과 부품기업 동반진출 전략, 둘째, 기술혁신을 통한 모듈화 및 공용 플랫폼 전략, 셋째, 지방정부 인센티브 정책 활용 전략이 그것이다. 특히 생산 네트워크 내 행위자들은 직서열 공급방식을 통한 부품 공급망을 따라 전후방 연계의 흐름이 나타났으며 관계성이 강화되었다. 따라서 부품기업들은 원활한 협력 체제를 위해 전방기업 및 모듈 단위 중심으로 집적하였다. 그 결과 북쪽의 베이징 현대를 중심으로 하는 북쪽 지역, 남쪽의 동풍열달기아를 중심으로 하는 남쪽 지역, 공용 부품을 공급하기 위한 칭다오를 중심으로 하는 중부 지역, 일반 공용 부품 및 원자재를 공급하는 상하이를 중심으로 하는 기타 지역으로 생산 공간의 분화가 나타났다.

This paper presents an improved learning-based visual inspection method for auto parts inspection in severe lighting changes. Automobile sunroof frames are produced automatically by robots in most production lines. In the sunroof frame manufacturing process, there is a quality problem with some parts such as volts are missed. Instead of manual sampling inspection using some mechanical jig instruments, a learning-based machine vision system was proposed in the previous research[1]. But, in applying the actual sunroof frame production process, the inspection accuracy of the proposed vision system is much lowered because of severe illumination changes. In order to overcome this capricious environment, some selective feature vectors and cascade classifiers are used for each auto parts. And we are able to improve the inspection accuracy through the re-learning concept for the misclassified data. The effectiveness of the proposed visual inspection method is verified through sufficient experiments in a real sunroof production line.

Due to its capabilities, RFID (Radio Frequency IDentification) has shown its applicability in various areas of business operations. This study describes the successful RFID system implemented in the auto parts manufacturing company called "E" to improve the efficiency of auto parts painting process management. The findings of this study show that an RFID system could help companies reduce manufacturing cost, inventory, and error rate in the auto-parts painting process. The RFID system descried in this study also demonstrates that an RFID system could make production data available real time to the company's ERP system and thus, managers and supervisors on the shop floor are able to make more informed business decisions. The findings of this study imply that RFID systems can be used to improve the efficiency of various manufacturing operations in companies. This study also provides IT professionals with practical guidelines for an effective implementation of RFID systems. In other words, it provides IT practitioners with the information on the success factors for implementing RFID systems as well as potential problems and solutions to them when implementing RFID systems.

Data mining is the process of finding and analyzing data from a big database and summarizing it into useful information for a decision-making. A variety of data mining techniques have been being used for wide range of industries. One application of those is especially so for gathering meaningful information from process data in manufacturing factories for quality improvement. The purpose of this paper is to provide a methodology to improve manufacturing quality of fuel tanks which are auto-parts. The methodology is to analyse influential attributes and establish a model for optimal manufacturing condition of fuel tanks to improve the quality using decision tree, association rule, and feature selection.

The existing (q)Z-source PWM AC-AC converters have limited voltage gain because of the equivalent series resistance in the Z-source inductor. In order to obtain higher voltage gain than (q)Z-source AC-AC converters, a coupled inductor (or transformer) based Z-source AC-AC converter is proposed in this paper. By increasing turns ratio of the coupled inductor more than 1, the proposed converter can obtain higher output voltage than (q)Z-source converters with the same duty ratio. A 120 W prototype AC-AC converter is built and tested to verify performances of the proposed converter.

이차전지의 수명 평가는 크게 Cycle life test 와 Calendar life test로 나뉘어져서 평가 되고 있다. Cycle life test로 수명 검증을 위해서는 일반적으로 3000 사이클 이상 테스트를 진행 하여야 하지만 이 방법은 시간이 장기화 되어 신뢰성 검증 및 새로운 부품 적용에 한계가 따른다. 따라서 본 논문에서는 고온 챔버 및 사이클 시험기를 사용하여 빠른 시간 내에 평가를 할 수 있는 가속시험법을 적용하여 수명을 평가 한 연구결과를 발표하고자 한다.
