  • The quality of a part has directly effect on part reliability. In the basis of MIL-HDBK-217F model, it is the determined rule that part's quality level should follow its nominal one written in its specification. If quality information is unknown, quality level of the part should be determined as 'Lower'. However, the prediction model is said to be short in reflecting parts applying 'state-of-the-art' technology and result in over-estimated failure rate by some reliability-related authorities or research institutes. In this study, the reliability prediction results by the model of MIL-HDBK-217F and Telcordia SR-332 are compared and analyzed to verify whether the statement is reasonable or not.

  • Purpose: This study aims to examine such relationships as the experiential value that customers respond to with regard to maintenance service by empirically revealing how the quality of auto maintenance and repair service affects both customer satisfaction and intention to reuse the same service through the Perceived-experiential Value of customers. Research design, data and methodology: The research model was designed with service qualities such as human quality, material quality, interaction quality, and system quality as independent variables, perceived-experiential value as a parameter, and service satisfaction and return visit intention as dependent variables. Through a questionnaire composed of 24 items, a total of 319 survey data from customers with the experience of using car maintenance service centers in Korea were collected and analyzed using a structural equation. Results: The material quality did not affect the customers' perceived-experiential value, whereas the interaction quality had the greatest influence. It is confirmed that human quality, interaction quality, and system quality can generate customer satisfaction and repurchase intention through the perceived-experiential value. Conclusions: The experiential value of customers can play an important medium role in improving satisfaction, with customers considering interaction quality important. Therefore, the auto maintenance and repair service should consider relationship-focused service strategies.

  • 글로벌 환경에서 항공사는 고객 만족을 통해 경쟁력을 확보하고 이윤을 창출하기 위해 노력하고 있다. 고객에게 서비스를 제공하기 위해 가장 선행되어야 할 것이 항공기의 안전이며, 안전의 실현을 위해 기본이 되어야 할 것이 정비품질의 지속적 유지이다. 항공 기술의 발전 정도는 상상할 수 없을 만큼 빠르게 진행되고 있으나, 정비품질 유지를 위해 일선 현장에서 업무하는 항공정비사의 제반 환경은 크게 변함이 없는 실정이다. 본 연구에서는 항공정비사에게 제공되는 교육훈련과 안전문화의 수준을 파악하고 자아존중감이 정비품질에 미치는 영향을 알아보고자 한다. 기존 선행연구는 정비사의 교육훈련, 조직성과 ,직무스트레스 등과 같은 연구는 있었으나, 정비품질과 관련된 연구는 부족하였다. 따라서 본 연구는 정비품질에 영향을 미치는 변수 간의 관계를 파악하고 실증분석을 통한 정비품질 향상을 위한 시사점을 제시하고자 한다.

  • Maintenance of quality of the compaction is accomplished with the plate load test and density management in roadbed. With the different structure differently the quality of roadbed evaluates indirectly as density and bearing capacity. Control of quality of the compaction very importance but the maintenance of quality is managed still so far with the paper. Recognizes the importance of maintenance of quality from the present paper consequently, and develops a data base one maintenance of quality system with hereafter is expected with the fact that the big help will become in DATA BASE system roadbed plan which is continuous and maintenance of quality.

  • Currently, in the course of introducing rolling stocks, RAMS standard and management by system engineering method apply to rolling stock system. Technical elements and results applied in system introduction phase are just used in acquisition stage, and these are not applied to the standard in railway site. Therefore, it is difficult to apply to standardized technology and quality assurance measure. Due to the establishment of the EU, railway operation system is internationalized and the international railway standards are being discussed in various ways. In addition, standardization is expanded from manufacture to operation and maintenance. It is to provide consistent standard in quality, cost calculation of maintenance technology, maintenance technology and quality assurance in case of international railway safety incidents. Therefore, this study is to find technology, quality and cost management model to be used for choosing railway-operation guidance by considering how technologies & quality have changed in system life cycle, compared with estimated standards, based on the technologies & quality-related result in the process of getting new rolling stocks and management guidance for operation & maintenance process.

  • In order to cope with the violent environment of surrounding enterprises, development of new products, advance to other industry field, unification or abolition of factories and rationlization of labor are needed. But production process being made quality and using process after shipment are the things that we have to think about, first of all and to practice always. Insurance problem of reliability, that is, the positive quality maintenance that has being presented many debate issues recently, will be studied. The accident of nuclear power-plant in America, in connection with reliability maintenance and human engineering, will be analyzed. But as its accident details is not announced, in this study, it is a sort of method of methodology to be studied this paper rather than studying the fact of the accident. Therefore this study will be done as follows, For reliability study. 1. Investigation of problems. 2. Quality maintenance activity and reliability maintenance activity 3. Reliability acquisition in production process, 4. Reliability maintenance after shipment. 5. Conclusion. In addition to stating above, it is sure that liberalization of trade, interchange between nations and strengthening of international competition ability, etc. need high quality. But possibility that quality maintenance or reliability aquisition needs understanding and cooperation of consumer, will be stated.

  • Since the most part of maintenance work for EMU depends on the worker's know-how, the quality of maintenance is different according to the worker's skill and experience. Especially EMU is composed of the various parts such as electrics, electronics, communication, signal, and machinery, etc., and performs its function by their organic work. Therefore it is very difficult to improve the quality of maintenance for EMU. In this paper we purpose how to change the know-how-based maintenance method to knowledge-based maintenance method. Consequently we can ensure the quality of maintenance for EMU, and improve the quality by continuous maintaining the knowledge.
