As the result of processing improvement of Telephone Dial by substituting. Synthetic Resin for metalic materials, improved characteristics of quality can be gained as follow. 1. By the improvement of structure and assembling of the Telephone Dial, the complex process of manufacture can be a simplified one, and at the same time the working process can be done in the form of assembly. 2. In the efficiency test of the Telephone Dial, the noise decreases by 5% compared with the first test. In the test of life and environment, it accords with the standard of the Ministry of Communications and its function betters. 3. By using synthetic resins instead of metalic materials the cost can be reduced by \340 than the first improvement and it also brings the heightend value.

This paper deals with a case study of layout design and improvement in medium and small-sized manufacturing factories. The shop layout affects greatly the productivity of manufacturing systems and we introduce some cases in which shop layouts are changed to improve the productivity step by step. Based on case studies, we propose also some guides to improve and design the shop layout in medium and small-sized manufacturing factories.

This paper deals with a case study about productivity improvement in medium and small-sized manufacturing factories. It is popular to improve the productivity of lines by shortening the production cycles and assigning multi jobs to workers. We analyze the production lines and improve the productivity in the case study through multi-functional workers and shortened production lines. Based on the case study, we propose some guidelines to improve the productivity of production lines.

This paper suggests a procedure to define business process improvement (BPI) projects with analysis results based on the cause-and-effect chain. The procedure developed in this paper focuses on eliminating root causes of business problems resulted from abnormal events occurred in business process executions. First, we develop three criteria used to make clusters of the root causes where a cluster of root causes will be eliminated together by a BPI project defined based on the cluster. Second, we develop a method to formulate desired expectations from the BPI project. Also, we suggest a method to calculate the relative importance of the BPI projects that help a BPI organization determine priorities of them. We illustrate the procedure and the methods with some examples for the domestic mail delivery process in the postal service industry.

서비스 산업은 21세기 새로운 비즈니스 핵심으로 부각되고 있다. 현대 산업에서 서비스 산업은 제조업을 지원하는 산업에서 탈피하여 제조업의 성장을 리드하는 산업으로 급부상하였다. 기업들은 기존 서비스의 개선을 통해 고객들의 다양한 요구사항을 충족시켜 주고자 하였으나, 서비스 개발자의 직관적인 판단에 근거한 서비스의 개선은 높은 실패율을 보이고 있다. 따라서 본 논문에서는 서비스 개발자의 개선 방향성을 지원하기 위해 서비스 개선방법론을 개발하였다. 이 방법론은 120개의 수집된 사례를 바탕으로 TRIZ 모델의 개념을 활용하여 개발되었다. 그 결과 사례 기반 서비스 개선 방법론(Case-based Service Improvement Methodolog; CSIM)이 개발되었고, 이는 서비스 개발자의 창의적인 문제해결을 지원하는 도구로 활용될 수 있을 것이다.

One solution to the estimation of product reliability during the development phase is to measure reliability improvement over time and compare this improvement to previous product development progress. This paper presents the reliability growth theory and applies it to some subsystems of vehicles during their design, development and prototype testing. The data presented illustrates explicitly the prediction of the reliability growth in the product development cycle. The application of these techniques is a part of the product assurance function that plays an important role in product reliability improvement.

Productivity relates output to input and also integrates performance aspects of quality, efficiency and effectiveness. Productivity improvement are associated with efficiency and effectiveness, productivity index involved quality and flexibility, integrated productivity measurement system, and other factors. This study focused on the productivity improvement that involved the opportunity costs such as qualify costs and flexibility effects.

As quality becomes a primary leading factor of organizational success, various management strategies have been introduced to improve quality competitiveness. Quality competitiveness, however, is difficult to measure and numerous organizations are struggling to set realistic improvement objectives. The primary purpose of this research is to propose a systematic approach to help the practitioners develop an improvement plan for their organizational quality competitiveness. This approach employs DEA(Data Envelopment Analysis) to evaluate relative efficiency among companies which make efforts to improve their quality competitiveness. It presents an integer programming model to elicit an optimal improvement plan for meeting a target level. A decision support system is also developed for the managers to plan a sequential improvement plan based on both DEA model and the integer programming model.

This study tried to propose plan to prevent human error of railroad driver among human error of railroad worker which takes great share in railroad accident. For this, in order to maintain correlation between the accident actually occurred after the opening of high-speed railroad and experience of accident that did not happened, survey on respondent was analyzed by conducting survey on KTX captain who is working in driving work of high-speed railroad, and instruction management team manager who manages KTX captain and captain. This thesis classified the factors by human factor, job factor, environment factor, organization factor, and established human error management model by comparing and analyzing how each factors have spatial interrelations with a railroad accident. The purpose of this study is to contribute to make safe railroad, and reliable railroad by preventing human error accident by minimizing human error of high-speed railroad drivers, and improving driving workers to cope accurately and fast with irregularities through various institutional improvement, improvement of driving facilities, improvement of operating room environment, and improvement of education system.
