QS-9000 was established by Chrysler, Ford, General Motors and some Truck Manufactures to solve problems of efforts to prepare original standards for each company. When we compare the requirements in QS-9000 with those in ISO 9000, we may observe that those of QS-9000 are more specific, since the user of the standard is limited to the automobile industry. In particular, the requirements on statistical techniques are described in more detail. In this paper, we present the requirements on statistical techniques in QS-9000. Specifically, we review the contents of QS-9000 and explore the philosophy and the minimum requirement on statistical techniques behind the description.

The company Daewoo Precision Industries imported fine blanking press of 40 tons from Switzerland with fine blanking tool in order to produce the fuse part of bomb in 1978 at first in Korea. About 1985 the first fine blanking tool for producing the door lock parts was manufactured in the company Gold Star (now LG). And then this technology was grown up with the growth of automobile industries in Korea. Now 31 companies are closely related to the fine blanking technology and there are total 146 fine blanking presses in Korea. The developments of fine blanking technology in industries have been oriented to the production of precise fine blanking parts, the reduction of die roll height on fine blanking parts, the production of complex fine blanking parts with progressive fine blanking tool including forming and forging technology, the production of high-strength steel fine blanking parts and so on. Some R&D activities in KITECH were introduced.

It was known that the excellent wear resistance of hyper eutectic aluminum alloy is based on the primary Si particles which are distributed in the base metal. When the primary Si volume fraction increases, the smaller size have excellent wear resistance characteristics. However, this trend always does not match. There is no investigation result based on the materials and methods for real using parts. In this study, using the automotive parts manufacturer currently in use hyper eutectic Al alloy tensile test specimen type sample was fabricated by 350Ton high pressure die-casting machine. Then, fluidity, tensile, impact and wear resistance properties were evaluated. If the casting quality, primary Si size, fraction and distribution are similar, mechanical properties and wear resistance are equivalent.

The forging industry is composed of those plants that make parts to order for customers; or make parts for their own company's internal use; or make standard parts for resale. Also, the forging industry is closely related with automobile industry and ship building industry - Korea's major export industry. But, it is hard to find the Korea's forging industry's statistical analysis because it is not revealed with final product. In this paper, we perform statistical analysis using the micro data service provided by the Statistics Korea. We focus on the analysis of production costs as well as the status of forging company and their employee.

When we try to design a production planning system for a manufacturing company, it is a time consuming task to analyze various planning activities and identify inter-relationship among a lot of decisions made for the production planning. Most of the research efforts have been concentrated to well-organized independent decision-making problems that may usually be identified only after analyzing the characteristics of the decision-making process as a whole. In this paper, a methodology is suggested to characterize the whole process of the production planning for a manufacturing company and reduce the complexity of decision-making problems. The methodology is based on an experience of developing a production planning software for an automobile component manufacturer in korea. First, it is explained how to identify and represent the dependency among various decision-making variables. And a methodology is proposed to analyze the identified dependency among decision variables and identify decision-making process. Lastly, a practical example is provided to illustrate the analysis procedure in this paper.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to product development projects and introduces the application cases. This product development project management process model is composed of five top processes of initiation and preparation, planning, implementation management, control, and termination and transfer. The five processes are re-divided into 18 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. This model is applied to the new car development project of a Korean automobile company and introduces the cases, which shows a project charter, a work breakdown structure, a project schedule, a progress s-curve, a risk register, and a performance report.

Automobile airbag deployment process has been studied with MADYMO software. Based on the FMVSS208 and USNCAP(United States New Car Assessment Program) regulations, four parameters were chosen for the design improvement with reference to the 5th percentile female passenger dummy: time to fire, vent hole size, tether length and tank test pressure of inflator. Sensitivity analyses based on orthogonal arrays show that enhanced protection of small females can be achieved with improved USNCAP rating within the boundary of FMVSS 208.

The purpose of this paper is to increase the effectiveness of decreasing time - load and cost down in manufacturing company using the new way of regulating standard time - load. Let us take an example of K automobile factory. This company have avoided the used to way of regulating standard ti me load in staff members and increased the effectiveness of decreasing time - load having participated all members centering around the Q.C circle. Here, We can take conclusions as below. 1. We could improve the consciousness of question and the consciousness of efficiency progress as a result of new way. 2. We could encourage the activation of organization and working desire of all members to be participated.

보험회사가 보험가입자의 정확한 위험도를 측정하여, 현재 보험료 수준으로 해당 가입자를 보험에 가입하도록 허용하는 것이 보험회사에게 손해인지 여부를 판정하는 보험회사의 활동을 언더라이팅이라 한다. 언더라이팅 시스템을 구축하는 방법으로는 기존 전통적 방법과 통계모형을 활용하는 방법이 있다. 기존의 요율산출방법에 따라 위험집단의 위험도 수준을 정하고, 해당 위험집단에 속한 가입자의 위험도를 기계적으로 계산하는 전통적인 방법은 모형의 이해가 용이하고, 사용이 편리하나 통계적으로 부합된 모형이라고 할 수는 없다. 본 연구에서는 우리나라 자동차보험 분야에서 언더라이팅 기준을 구축하기 위해 통계모형을 활용하는 방법으로 일반화가법모형을 활용하는 방안을 제시하고 분석하였다. 본 연구의 결과는 현재 자동차보험 요율산출에 사용되고 있는 변수들의 유의성을 판단하는 데에도 활용될 수 있을 것이다.

본 연구는 제조기업에서 업무 상 비용절감과 처리속도를 빠르게 할뿐만 아니라, 향후 업무환경 변화에 능동적으로 대처할 수 있는 통합 경영관리시스템을 설계하는 데 있다. 현재 판매되고 있는 범용 경영관리시스템은 많은 추가적인 노력없이는 각 기업의 고유업무를 반영하는 데에 한계점이 있으므로, 본 연구에서는 예측생산 및 주문생산 전략을 동시에 가지는 자동차부품 제조업체를 대상업체로 선정하여 해당업체의 업무에 특화하여 경영관리시스템을 설계하였다. 시스템설계는 전체 시스템의 각 기능 모듈에 대하여 불필요한 업무처리의 발생을 줄이기 위한 장치를 추가함으로써 제품원가에 반영되는 제조 간접비의 발생을 최소화하도록 하였다. 또한 구축될 시스템에 현장상황이 적시에 반영되어 시스템의 출력이 실효성을 가질 수 있도록 하기 위해 각 기능 모듈간의 연계성을 고려하였으며 현장상황을 관찰하는 모니터링 모듈과 각 기능모듈간의 데이터 흐름을 원활히 할 수 있도록 시스템을 설계하였다.
