남미영,이주성 한국경영공학회 2010 한국경영공학회지 Vol.15 No.1

본 연구에서는 한국항공우주산업(KAI)의 지식경영 체계를 분석하여 항공 산업분야의 지식경영 성공요소를 도출하였다. 최첨단 기술지식이 집적된 항공기 개발 산업은 여타의 산업분야보다 지식경영의 중요도가 높다. KAI는 항공기 개발을 위한 기술 및 지식기반이 미흡한 상황에서 짧은 기간 안에 T-50 개발을 성공하였다. 본 연구의 목표는 이러한 성과를 일구어 낸 KAI의 지식경영의 주요 성공요소를 분석하는 것이다. 본 연구에서는 지식경영의 조직 생태계와 정보기술 활용의 두가지 관점을 바탕으로 기존문헌 연구를 통해 분석된 지식경영전략과 성공요소 및 항공 산업의 특성을 종합하여 항공 산업의 지식경영평가도구를 개발하였다. 이를 적용하여 KAI의 경영층 및 실무자 인터뷰를 통해 KAI의 지식경영을 구체적으로 분석하였다. 연구결과 KAI의 지식경영은 공통적인 성공요소인 전략, 지식경영시스템, 문화 및 사람, 프로세스 부분에서 높은 평가를 받았으며, 항공 산업의 특성과 관련된 시스템 연계, 보안유지, 안전관리 측면에서는 다소 낮게 평가되었다. 이러한 항공 산업 지식경영의 취약점을 보완하기 위한 제언을 기술하였다.

신정훈,박희준,김홍성 한국경영공학회 2009 한국경영공학회지 Vol.14 No.1

식경영(Knowledge Management)이라는 경영의 새로운 패러다임(paradigm)이 나타났으며 많은 기업들이 지식경영을 도입하여 기업경영에 활용하고 있다. 그리고 대부분 기업들의 지식경영은 지식경영시스템(Knowledge Management System) 활용 측면에 머물러있다. 이에 본 연구는 지식경영시스템 성과, 다시 말해 지식경영시스템 만족도, 지식경영시스템 사용도 변수와 지식경영시스템 특성, 서비스 특성, 조직환경 특성 변수 간의 관계를 살펴봄으로써 기업이 지식경영시스템을 활용하여 지식경영을 수행하는데 있어 도움을 주고자 한다. 구체적으로 본 연구에서는 지식경영, 지식경영시스템 및 정보시스템(Information System) 성공 등의 관련 기존 연구를 토대로 변수를 도출하였다. 개념적 연구모형은 DeLone & MeLean의 Updated D&M IS(Information System) Success Model(2003)을 기본으로 하며, 지식경영 선행연구를 통하여 조직환경 특성을 추가하였다. 또한 구조방정식의 통계적 방법을 통하여 연구 가설검정을 실시하였으며, 결과적으로 지식경영시스템 특성의 시스템 지원성, 지식 적합성, 서비스 특성의 서비스 상호작용, 지식경영 특성의 리더십, 조직문화는 지식경영시스템 만족도에 영향을 미치는 것으로 나타났다. 또한 지식경영시스템의 지식 현재성은 지식경영시스템 사용도에 영향을 미치는 것으로 나타났다.

Estimation problems for failure processes in repairable systems with preventive maintenance

정일한 ( Il Han Chung ) 한국경영공학회 2014 한국경영공학회지 Vol.19 No.2

Estimation problems of failure parameters and maintenance effects in repairable systems are considered. A proportional age reduction model for corrective and preventive maintenances under which the system ages are reduced after maintenances is assumed. The failure data(the points of corrective maintenance) and the points of preventive maintenance are given for analysis, and the maximum likelihood method is used to estimate the parameters of failure distribution and age reduction factors for corrective and preventive maintenances. Four kinds (two kinds of encoding and selection methods) of genetic algorithm is proposed to maximize likelihood function. In numerical examples, We employ simulation to generate failure times and GA is used to estimate parameters of Weibull distribution and improvement factor of PM and CM. In addition, there is comparison of performance of genetic algorithms.

This paper aims at improvement in core competencies of food service providers by using Quality Function Deployment and Fuzzy Set Theory. This research identified customer requirements through customer surveys and monitoring customer feedback and determined service characteristics by expert interviews for the quality function deployment. In addition, the fuzzy set theory was applied to transforming vague and subjective customer requirements into clear and objective numerical values. The top management and managers of food service providers can identify the priorities for improvement in service characteristics, on which they can focus.

직업정보 탐색과정에서 취업준비생과 취업사이트간의 사회네트워크 구조 등위성 탐색연구

By employing technical methods, this study aims to investigate phenomenon of sharing job-search sites among job applicants. This study places social network structure of the most commonly chosen and visited job-search site at its analytic center. Analysis result shows that out of all job-search sites, a center block exists which acts as the center of sharing information and that job information is shared around it. Also, because connection strength is low between blocks, sharing between blocks is minimal. Hence, information flow is low between blocks and there is a tendency to depend on the information provided by commonly shared blocks. Job-search sites shared partially different web sites at various visited times and hence, job-search sites showed different application of information.

In these days, many researchers have been studied research for advanced technology and national competitiveness. However, they do not research for public benefit and social weak person. Besides, these issues are attention as well as social welfare in terms of using new technology as a major emerging research issues. Also, social problems in national responsibility led to the starting point of sustainable system of social technology. By finding the cause of the problem and more in-depth approach that reflects the opinion of the people in social problems. However, Systematic researches for social problems are not enough. Thus, I studied best process for social problems through literature review. And I developed process for draw out best solution to public value from company and people. To achieve such purpose, first, the concepts of social problems were organized to clarify the study objects. And, the types of social problems were analyzed based on the literature review to draw out social issues. Second, I analyzed previous research based on developing process for draw out solutions. And I developed process step for social solutions. Third, the analyzed classifications of social problems were further divided into those for academic purposes and those applicable to national policies. Finally, I suggested best process for social solution considering literature review.

반도체의 결점 크기 분포를 이용한 신뢰도 추정

김경미 한국경영공학회 2010 한국경영공학회지 Vol.15 No.1

Random defects occur on wafers or glasses during the fabrication of semiconductor. Defects larger than a certain critical size cause the immediate device failures and such defects are called the yield defects. Any device with a yield defect is scrapped or repaired. On the other hand, defects smaller than a critical size are released to the customer and may or may not cause the device failure depending on the operating time and the operating condition. It is necessary to develop the defect size distribution in the operating time and the operating condition. Previously, the defect size distribution at time is assumed to be a parallel move of the defect size distribution at time 0. In this paper, we consider a defect growth model using a lognormal distribution and develop expressions on semiconductor reliability for the different distributions for the number of random defects in a device. The proposed model has benefits over the previous model in that random exponential defect growth is considered.

개발경험유무에 따른 발사체 신뢰도 및 실패원인 분석

홍혜진 ( Hye Jin Hong ),김경미 ( Kyung Mee Kim ) 한국경영공학회 2014 한국경영공학회지 Vol.19 No.2

In this paper, we analyze reliability and failure causes for the new and experienced developers of launch vehicles. Previously, such analysis has been performed ignoring the experience of the developers but only considering the different time periods. We find three new results which may help the new developer such as Korea. First, the new developer has a significantly lower reliability than the experienced developer at the lower stages of the launch vehicle. Second, the new developer has a significantly lower reliability than the experienced developer for the liquid-propellant rocket, but not for the solid rocket. Third, the new developer must focus on the separation subsystem in addition to the propulsion subsystem while the experienced developer focuses on the propulsion subsystems. Especially if the launch fails at the first stage, the failure cause for the experienced developer is mainly due to the propulsion or the structure subsystems but is widely spread over all subsystems for the new developer.

The purpose of this study is to investigate the impact of Triple-A supply chain on operational capabilities and firm performance. By using a structural equation modeling, we analyze the relationship among three constructs. Different from prior studies which examined the relationship between supply chain and firm performance in terms of supply chain efficiency, the contributions of this study are to highlight the importance of Triple-A supply chain which can respond to short-term and long term changes in volatile business environments and to empirically analyze the impact of Triple-A supply chain on operational capabilities and firm performance based on the data from manufacturing firms. Also, this study finds that operational capabilities mediate the relationship between Triple-A supply chain and firm performance. In other words, it is expected that Triple-A supply chain helps a firm to improve its operational capabilities and improved operational capabilities, in turn, leads to higher firm performance: higher marketing and financial performances of the firm.
