The strategic industry in Chungbuk province is the electric and electronic related industry. In the Chnugju region, the trend of major industry have change from the electric and electronic related industry to mechanical parts and components related industry include manufacturing of automobile and transportation. In this paper, we perform statistical analysis using the micro data service provided by the Statistics Korea, The CAGR of the number of employee and value-added value in the electric and electronic related industry during past 7 years are -7.1% and -13.2%, respectively while the CAGR in the mechanical parts related industry are 14.4% and 22.9%, respectively. However, value-added value per value of shipment of the mechanical related industry is lower than that of the electric and electronic related industry.

$D^*$ criterion is defined as a reference of the handling quality and ride comfortableness for lateral-directional automobile motion. However it is generally difficult to obtain the satisfied handling quality and ride comfortableness based on $D^*$ criterion by conventional two wheel steering system. In this study, a design method of model matching control system is proposed to obtain the satisfied $D^*$ response of 4 Wheel Steering.

In the recent day, shielding can was made of permalloy materials for automobile display instrument. The good roundness has an effect on magnetic property such as the low coercivity and the high permeability. But the products having the roundness is transformed by the heat treatment, the sending to the company and the assembly process. So for the stiffness of the edge, it is necessary for hemming process to be added in the deep drawing process. And it has the good appearance to create a smooth edge rather than a razor edge with urr. In this paper, it is controlled to get the best hemming product by the Pre-hemming angle($105^{\circ}$, $120^{\circ}$, $135^{\circ}$). And Possible process and tool design modification, which may lead to quality improvement in hemming were tested experimentally and using FEM. The commercial finite element program PAM-STAMPTM was used to simulate the pre-hemming process and hemming process, and the predictions were compared with experimental results according to the pre-hemming angle.

Many enterprises are looking for counterproposals to be survival through innovation activities and to be held on their continuous businesses for their business management environments nowadays. One of the innovation activities is an improvement of Loss and reinforcement of business structure through Lean, TPM. Another one is an improvement of these innovation activities and have achieved lots of outcomes (profits). But most these activities have been applied for only the industries in Automobile, Semiconductor, Aviation, Construction with large enter in Korea. And most of minor cable enterprises don't even try to import these innovation activities excluding some how the small and medium cable enterprise can import the LEAN / 6 Sigma activities effectively with some of sample in real small and medium cable company.

There are various methods to assess to company's outcome. Among them, the customers satisfaction, which is assessed by customers, is the most important. If the customers satisfaction is measured by the CSI based on the proper reliability and validity, you can apply the result for various marketing methods. Therefore, this study develops a model to assess CSI for an industry, specifically, local automotive industry based on the SEM that is already proven valid through assessing models such as ACSI, KCSI and NCSI. Moreover, this research can be utilized for marketing strategy helping customers to decide as an AHP model, one of the decision making method.

In recent, most of automobile industries adopt the concept of Just In Time production. The paternal manufacturers require their suppliers to supply parts just in time. It is very important for a subcontractor to produce the parts in the appointed time of delivery. This study develops a production information system for Woosin Industry, which is one of such subcontractor of Hundai Motors Company(HNC). The system is developed on Client/Server system. Firstly, three modules are developed, i.e., scheduling module to make a schedule, the subsystem of sales management to deal with the information about order of HMC, delivery of parts, and bill collecting, and the module for supporting material requirement planning and purchace of material.

Automobile markets are so fierce in the world market that every major manufacturer assure the buyer of the car by give a provocative warranty plan for their cars. For instance Hyundai motor company offer 10 years and 100,000 miles of warranty whichever comes first. But in order for this effort to be successful every critical component such as window switch has to be proven to be reliable in an adverse environment. Therefore, in this article reliability assessment criteria for window switch are established in terms of basic performance test, environment test and life test.

A telecooperation system supports synchronous cooperation among all the product development partners and enables compensation of deficits concerning traditional information/communication technologies. By analyzing the product development processes and communication scenarios of a company manufacturing automobile parts, the specifications for the suitable telecooperation system were defined. An integrated telecooperation platform that combines the commercial softwares with the new developed modules for customer-oriented functionalities was created as a product development guideline. Future work is strongly required in order to define the best way to improve the integrated platform, based on the functionality of ERP and PDM systems.

This paper presents a variant type process planning system for machining of dies for auto-body production. Through the analysis of dies and their manufacturing processes, the authors categorized the press dies into 15 groups according to the similarity of machining features. After critically reviewing current manufacturing procedures, a standard process plan was defined for each group. The authors present MP3D the process planning system built on the standard process plan database, and show how they apply it at the die manufacturing plant of an automobile company. MP3D is expected to reduce major losses in machining such as reworking caused by mistakenly uncut features and eventually to help to accumulate the knowledge of operators. The operation sheet MP3D produces is also used in monitoring the progress of manufacturing of dies. This paper explains the whole development cycle of a process planning system from process analysis to application so that it can help readers to develop and apply a process planning system to their machine shops.

Recently, many companies have applied data mining techniques to promote competitive power in the field of their business market. In this study, we address how data mining, that is a technique to enable to discover knowledge from a deluge of data, Is used in an executed project in order to support decision making of an enterprise. Also, we develope scoring model on customer attrition probability for automobile-insurance company using data mining techniques. The development of scoring model in domestic insurance is given as an example concretely.
