2011년 한-EU 자유무역협정 발효 이후, 한국 자동차 시장은 급성장하였으며 시장 내 기업 간 경쟁 양상은 심화되고 있다. 유럽산 자동차 기업은 가격 경쟁력을 보유하게 되었고, 이로 인해 한국 자동차 기업과의 경쟁이 격화되었다. 이와 같은 상황 속에서 한국 자동차 시장에 관한 다양한 연구가 수행되어왔으나, 시장 영향요인 분석과 소비자 분석 등의 연구가 주를 이루었고 시장 내 경쟁 다이나믹스 분석에 관한 연구는 전무한 상황이다. 본 연구에서는 한국 자동차 시장 내 주요 기업인 현대자동차, 기아자동차, 메르세데스-벤츠, BMW의 경쟁 다이나믹스를 분석하였다. Lotka-Volterra(LV) 모형을 사용하여 주요 기업들의 경쟁 관계를 모델링하였고, Moving Window 기법을 적용하여 시간의 흐름에 따른 기업 간 경쟁 다이나믹스를 분석하고 이를 정량적으로 도출하였다. 효과적인 해석을 위해, 도출된 경쟁 다이나믹스는 다양한 영향요인을 바탕으로 세분화되어 분석하였다.

Three big U.S. automakers have developed the QS-9000 quality system for their su, pp.iers. These automakers are requiring their su, pp.iers to implement the QS-9000 based quality system. This QS-9000 system is based upon the ISO 9000 series quality systems. This paper describes the differences between the ISO 9000 series requirements and the QS-9000 requirements. It also suggests the way to implement the QS-9000 quality systems for Korean su, pp.iers.

Automakers have been forcing their suppliers to guarantee qualities of parts. Then, the suppliers have met the fundamental quality requirements such as dimensions and functions, but they could not sufficiently satisfy the automakers' noise requirements yet because automatic noise inspection systems were little successfully adopted In mass-production lines. This study tried to develop a system for automatically checking noise radiated from a rotating engine part and filtering parts emitting noise higher than criteria: the upper limits of a overall noise level or a noise spectrum. A commercial noise measurement system was used for measuring noise, and then the noise data was transmitted to a governing program through OLE(object, linking and embedding) functions. The governing program, belonging to a total noise inspection system managed the noise measurement and analysis. This system was successfully adapted for distinguishing bad parts according to the noise criteria.

This research proposes a novel approach to tackle the challenge of categorizing unstructured customer complaints in the automotive industry. The goal is to identify potential vehicle defects based on the findings of our algorithm, which can assist automakers in mitigating significant losses and reputational damage caused by mass claims. To achieve this goal, our model uses the Word2Vec method to analyze large volumes of unstructured customer complaint data from the National Highway Traffic Safety Administration (NHTSA). By developing a score dictionary for eight pre-selected criteria, our algorithm can efficiently categorize complaints and detect potential vehicle defects. By calculating the score of each complaint, our algorithm can identify patterns and correlations that can indicate potential defects in the vehicle. One of the key benefits of this approach is its ability to handle a large volume of unstructured data, which can be challenging for traditional methods. By using machine learning techniques, we can extract meaningful insights from customer complaints, which can help automakers prioritize and address potential defects before they become widespread issues. In conclusion, this research provides a promising approach to categorize unstructured customer complaints in the automotive industry and identify potential vehicle defects. By leveraging the power of machine learning, we can help automakers improve the quality of their products and enhance customer satisfaction. Further studies can build upon this approach to explore other potential applications and expand its scope to other industries.

To improve passenger convenience and safety, today's vehicle is evolving into a "connected vehicle," which mounts various sensors, electronic control devices, and wired/wireless communication devices. However, as the number of connections to external networks via the various electronic devices of connected vehicles increases and the internal structures of vehicles become more complex, there is an increasing chance of encountering issues such as malfunctions due to various functional defects and hacking. Recalls and indemnifications due to such hacking or defects, which may occur as vehicles evolve into connected vehicles, are becoming a new risk for automakers, causing devastating financial losses. Therefore, automakers need to make voluntary efforts to comply with security ethics and strengthen their responsibilities. In this study, we investigated potential security issues that may occur under a connected vehicle environment (vehicle-to-vehicle, vehicle-to-infrastructure, and internal communication). Furthermore, we analyzed several case studies related to automaker's legal risks and responsibilities and identified the security requirements and necessary roles to be played by each player in the automobile development process (design, manufacturing, sales, and post-sales management) to enhance their responsibility, along with measures to manage their legal risks.

근래 소비자의 제품 선택은 단순한 소득 계층별이 아니라 다양한 라이프스타일에 따라서 변화되고 있으며, 그에 따라 수요의 다양화, 상품의 다품종화가 모든 산업에서 전개되고 있다. 즉 기업은 다양화, 다품종화 속에서 얼마나 생산성을 실현하느냐에 따라 미래 기업의 운명이 좌우되는 것이다. 본 논고에서는 제품개발에 있어서 상품성이 높은 제품개발에는 개발 과정에서의 표적시장 명확화가 불가결하다는 점에 인식에서 출발, 메이커만의 독자적 아이덴티티를 구축하여 브랜드 이미지를 형성하고, 그에 따른 브랜드 역할과 가치에 대해 자동차 사례를 중심으로 논의한 것이다. 이러한 브랜드 고유의 일관된 디자인 아이덴티티를 정립, 적용함으로서 상징성이나 감성적 성향이 점차 강조되어 가고 있는 제품속성에 대응, 고객이 만족하는 기대수준 이상의 가치를 제공하려는 데 의미가 있다.

Purpose - This study aims to identify new attributes by analyzing reviews conducted by global automaker customers and to examine the influence of these attributes on satisfaction ratings in the U.S. automobile sales market. The present study used J.D. Power for customer responses, which is the largest online review site in the USA. Design/methodology - Automobile customer reviews are valid data available to analyze the brand personality of the automaker. This study collected 2,998 survey responses from automobile companies in the U.S. automobile sales market. Keyword analysis, topic modeling, and the multiple regression analysis were used to analyze the data. Findings - Using topic modeling, the author analyzed 2,998 responses of the U.S. automobile brands. As a result, Topic 1 (Competence), Topic 5 (Sincerity), and Topic 6 (Prestige) attributes had positive effects, and Topic 2 (Sophistication) had a negative effect on overall customer responses. Topic 4 (Conspicuousness) did not have any statistical effect on this research. Topic 1, Topic 5, and Topic 6 factors also show the importance of buying factors. This present study has contributed to identifying a new attribute, personality. These findings will help global automakers better understand the impacts of Topic 1, Topic 5, and Topic 6 on purchasing a car. Originality/value - Contrary to a traditional approach to brand analysis using questionnaire survey methods, this study analyzed customer reviews using text mining. This study is timely research since a big data analysis is employed in order to identify direct responses to customers in the future.

About 100 years after the start of mass production by American car maker Ford in 1913, the automobile industry has come to a major transformation in 100 years. In this transformation period, automakers are facing the biggest challenge of converting power sources, the basis of automobiles, from existing internal combustion engines to electric vehicles. Hybrid vehicles have been released in Japan since the late 1990s, and changes in automobile power sources have occurred early. In order to gain global leadership in hybrid vehicles, Japanese automakers and the Japanese government joined forces to promote the growth of the domestic hybrid vehicle market. The government has implemented a policy to substantially subsidize the high price of hybrid cars compared to internal combustion engine cars by providing purchase subsidies and tax benefits to buyers. Toyota has increased its line-up of hybrid cars around the Prius and has further strengthened communication with customers for the sale of hybrid vehicles. As a result of continuing these efforts for about 20 years, the percentage of Japan's hybrid vehicle market in 2022 reached 51% for passenger cars. Recently, each country has been setting and promoting aggressive goals for electric vehicles that require a wider range of physical and institutional infrastructure than hybrid vehicles. This study aims to assess the growth of electric vehicles by looking at the trend of hybrid vehicles and how they've been distributed in the Japanese market.

America automakers are requiring their suppliers to implement the QS-9000 based quality system, through they have had a little lukewarm attitude. Therefore, our auto parts makers need to cope with the QS-9000. This paper describes the interrelationship between ISO 9000 requirements and the QS-9000 requirements, the way to solve the problems step by step that originate from the QS-9000 quality system auditing and QS-9000 tendancy.
