Manufacturing companies expand their revenue sources by advancing into upstream or downstream of business value chains with special focus on service. Such a new movement is called as servicizing. We introduce various successful cases of automobile industry in Korean and overseas countries. Information technology has been taking a critical role in automobile manufacturer's servicizing efforts leveraging their manufacturing capabilities and brand power. Servicizing cases include telematics, collision prevention, used-car sales, rental, and car life of Japanese, German and three Korean automobile companies.

최근 토요타 자동차의 대량 리콜 사태로 안전과 관련된 자동차 품질에 대한 관심과 중요성이 크게 부각되었다. 본 연구에서는 나날이 높아지고 있는 자동차 품질 기준과 생산 비용 절감, 공정 자동화 요구에 부응하기 위한 차체 저항 점 용접부 품질 검사 자동화 기술 개발을 위해 적용 가능한 센서들을 비교, 검토하였다. 알려진 비파괴 검사 방법은 초음파, 와전류, 방사선 검사법 등 다양한 방법들이 존재하지만, 이 연구에서는 생산 라인 현장 적용이 가능한 소형 센서들을 중심으로 검토 영역을 제한하였다. 검토된 비파괴 검사 방법은 총 5가지 종류로 종래의 수동 초음파 검사법, 집적된 탐촉자를 이용한 3차원 초음파 검사법, NAUT(Non-contact Air-coupled Ultrasonic Test), EMAT(EletroMagnetic Acoustic Test), 그리고 너겟 프로파일러$^{TM}$이다. 이 연구에서는 각 검사법의 원리와 장단점을 설명하고 생산 라인 적용에 필요한 필수 항목들에 대해 고찰하였다.

This study analyzes the characteristics and change factors of technological cooperation networks in the automotive industry. Using Social Network Analysis (SNA) of 112,009 autonomous driving-related patents filed from 2000 to 2017 by major automotive firms in the world, we investigate the structure of the technological cooperation network. Network characteristics such as density are analyzed through structural characteristic analysis among the network analysis indicators. The structural characteristics of the technology cooperation network are confirmed through analysis of status characteristic indicators, such as the degree of centrality, betweenness centrality, and closeness centrality. Results show that car makers such as Toyota and Hyundai Motors, as well as parts suppliers such as Bosch and Continental, have high-performance technology developments related to autonomous driving. The structural characteristics of the network show that companies participating in cooperative networks for autonomous driving technology development have increased in number and are diversified, and all of the status characteristics indicators have decreased. This can be interpreted as an increasing number of horizontal and complementary forms of technological cooperation between firms. In addition, it was confirmed that the number of participants in the field of autonomous driving technology has increased, and the networks have become more complex.

This study employed text mining techniques like frequency analysis, word clouds, and LDA topic modeling to assess consumer satisfaction and dissatisfaction with Hyundai Motor Company in the Chinese market, compared to brands such as Toyota, Volkswagen, Buick, and Geely. Focusing on compact vehicles from these brands between 2021 and 2023, this study analyzed customer reviews. The results indicated Hyundai Avante's positive factors, including a long wheelbase. However, it also highlighted dissatisfaction aspects like Manipulate, engine performance, trunk space, chassis and suspension, safety features, quantity and brand of audio speakers, music membership service, separation band, screen reflection, CarLife, and map services. Addressing these issues could significantly enhance Hyundai's competitiveness in the Chinese market. Previous studies mainly focused on literature research and surveys, which only revealed consumer perceptions limited to the variables set by the researchers. This study, through text mining and comparing various car brands, aims to gain a deeper understanding of market trends and consumer preferences, providing useful information for marketing strategies of Hyundai and other brands in the Chinese market.
