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.

Purpose The purpose of this study is to analyze the changes in the technology convergence network of national R&D patent performance and the differences in technology convergence research trends between independent R&D and collaborative R&D. Methods Co-occurrence networks have been established in which multiple International Patent Classification (IPC) codes appear per patent in 2014 and 2017. Then, network analysis methods and QAP (Quadratic Assignment Procedure) analysis methods have been used in this study. Results As a result, this study shows that the degree of linkage between technologies related to national R&D projects has increased over time. The main fields of technology convergence research have been changed to ICT fields such as digital and data (G06Q, G06F) and bio fields such as food (A23L) and cosmetics (A61Q). The Ministry of Agriculture, Food and Rural Affairs actively conducts convergence research by introducing new technologies such as ICT. The Ministry of Health and Welfare actively conducts convergence research in the field of bio-health. Conclusion This study showed the changes and characteristics of technology networks of convergence R&D and collaborative R&D. The results of this study are expected to be used as a guideline for decision making in the government's R&D policies.

Purpose Establish a plan to increase technology commercialization capability based on absorption capability and R&D capability Methods Analyze causal relationship between factors through structural equation model Results Absorption capability has a significant effect on both R&D capability and technology commercialization capability, but R&D capability has an effect on the productization capability of the technology commercialization capability, but not the manufacturing capability and marketing capability of the technology commercialization capability. Conclusion First, it is important to increase the absorption capacity in order to increase the R&D capacity. Second, in order to acquire external knowledge and information, various networks with the outside must be formed. Third, it is necessary to establish clear goals for R&D and practice it with manpower, equipment, and funds.

Purpose Present Worth (PW) and Internal Rate of Return (IRR) are two popular economic decision criteria in engineering economic analysis, but PW is preferred to IRR because of several deficiencies including multiple internal rates of return (MROR). Research in MROR has mainly focused on two areas: conditions for MROR occurrence and unique positive IRR, and solutions to MROR. This paper discusses MROR problems in depth. Methods In two areas of MROR, main and recent research streams are reviewed and illustrated with numerical examples. Also, a concrete measure to clarify the meaning of AIRR(Average IRR) proposed by Magni(2010) to resolve several problems of IRR is provided. Results Scopes and levels to cover MROR problems in textbooks of engineering economy (EE) field are surveyed and a new pedagogical proposal for instructors to teach MROR problems in EE class is presented. Conclusion Despite several drawbacks including MROR, surveys for managers have consistently shown that substantial practitioners still favor IRR. Results and proposals in this article will be helpful to enhance the study achievement for IRR in EE class of university.

Network Revenue Management with Time and Precedence Constraints

( Lee¸ Haeng-ju ) 한국경영공학회 2020 한국경영공학회지 Vol.25 No.4

This paper explores the network revenue management problem where a firm sells products composed of multiple resources. Unlike the traditional network revenue management problem, the products have time and precedence constraints. This means that some products may be infeasible to deliver. To filter out those infeasible products, this paper proposes a simple linear programming. The firm starts the sales horizon only with the feasible products. The dynamic programming can be formulated to have the optimal policy, but it may suffer from the curse of dimensionality. To overcome this difficulty, this paper proposes the linear programming based heuristic. The numerical study shows that the heuristic can save the computation time greatly while providing a reasonably good solution.

퍼지 베이지안 네트워크와 증거 이론을 이용한 FTA-FMEA 통합시스템에 의한 오류진단

최성운 ( Choi¸ Sungwoon ) 한국경영공학회 2020 한국경영공학회지 Vol.25 No.4

Purpose This study presents a combined model of Fault Tree Analysis (FTA) and Failure Mode and Effects Analysis (FMEA) using evidence theory and Fuzzy Bayesian Network (FBN) under uncertain circumstances which are caused by the presence of incompleteness, randomness and ambiguity of failure modes. Methods In order to identify the critical failure modes according to the multi-level FTA-FMEA, the Trapezoidal Distribution-Type Basic Belief Assignment (TrDTBBA) is used to consider the viewpoints of experts and to resolve the conflicts of evidence The proposed FTA-FMEA-FBN model derives fuzzy posterior probabilities to implement fault diagnosis approach which is more suitable than fuzzy prior probabilities when conducting qualitative reasoning of vague probability. Results A novel method for identifying the critical failure modes according to the level of hierarchical Bill of Material (BOM) is based on the proposed FTA-FMEA-FBN integrated model that illustrates chassis system consisting of 6 components, 4 modules and 6 parts. Conclusion This suggested FTA-FMEA-FBN model is convenient for a risk evaluation in the following uncertain circumstances: 1) The information of failure modes are incomplete, 2) The numbers of failure modes comprised of three levels are too abundant, 3) The probabilities of failure modes have a lack of quantification data. The fusion strategy of those three risk techniques implements computational efficiency and provides a synergistic effect to accurately identify the critical failure modes under uncertain circumstances.

전영호 한국경영공학회 2019 한국경영공학회지 Vol.24 No.4

As AI(artificial intelligence) is actively researched, it is being applied in various fields such as natural language processing, video and voice processing. However, voices pointing out the technical limitations of deep learning are spreading, and accordingly, researches for solving the technical limitations of deep learning are being actively conducted. In this paper, BERT, well known as the pre-training model of natural language processing, was applied to the classification problem of legal counseling data to verify the effect of transfer learning. Using BERT pre-trained data, the Transformer classification model was implemented and applied to the problem of legal counseling data classification, which showed higher accuracy than the traditional machine learning algorithm.
