심화된 경쟁환경속에서 기업들은 정보기술을 이용해 데이터 웨어하우스를 구축하고 그 자료를 바탕으로 데이터 마이닝을 실시해 전략적 의사결정을 하고 있다. 이런 가운데 국내 업계와 학계에서 데이터 마이닝에 대한 다양한 연구가 활발하게 추진되고 있다. 이런 연구를 체계화, 실용화하기 위해 데이터 마이닝 연구회가 설립되어 관심을 끌고 있다. 데이터 마이닝 연구회의 초대 위원장을 맡은 지원철 교수를 통해 창립배경과 활동방향을 들어봤다.

지난 수십 년 간 연구자들은 효과적인 진료지원시스템을 개발하기 위해 다양한 도구와 방법론들을 제안하였고 지금도 새로운 방법론과 도구들을 계속적으로 개발하고 있다. 그 중에서 흉통으로 응급실에 내원한 노인환자에 대한 정확한 진단은 중요한 이슈 중의 하나였다. 따라서 많은 연구자들이 의사의 진단 능력을 향상시키기 위한 지능적인 의료의사결정과 시스템 개발에 투신하고 있지만 전통적인 의료시스템에 따른 대부분의 진료의사결정이 단일 분류기(classifier)에 기반하고 있어 만족스런 성능을 보여주지 못하고 있는 것이 현실이다. 따라서 이 논문은 앙상블 전략을 활용하여 의사들이 노인환자들의 흉통을 더 정확하고 빠르게 진단하는데 있어 도움을 줄 수 있게 하였다. 의사결정나무, 인공신경망, SVM 모델을 결합한 앙상블 기법을 실제 응급실에서 수집한 응급실 자료에 적용하였고, 그 결과 단일 분류기를 사용하는 것에 비해 월등히 향상된 진단 성과를 보이는 것을 관찰 할 수 있었다.

최근 기업 정보에 대한 온톨로지 구축 필요성이 대두되면서 기업의 투자 비용과 시간을 고려한 온톨로지 구축 대상 선정을 위한 효율적인 기법이 요구되고 있다. 그러나 기존의 온톨로지 구축 방법론에서 제시한 대상선정 기법은 전체를 대상으로 하거나, 특정 영역만을 대상으로 한다는 한계가 있다. 본 논문에서는 정성적요소를 포함하는 다기준 의사결정에서 정량적인 평가를 지원하는 의사결정지원기법인 AHP(Analytic Hierarchy Process:계층화분석법)기법을 온톨로지 구축 대상 선정에 적용하는 방법을 제안한다. 이러한 방법을 통해 온톨로지 적용대상의 우선순위를 결정지을 수 있으며, 기업의 온톨로지 구축시 목표와 전략에 맞는 대상선정의 정량적 기준을 제공할 수 있다.

Scenarios are an effective tool for supporting a company to be successful in its increasingly complex, changing business environment. They are especialy effective in dealing with uncertainties. This paper show how business managers or supervisors can develop scenario-based business strategies. This is explained by the case study of MVNO (Mobile Virtual Network Operator) in Korean mobile service market. In addition, we discuss on theoretical background of scenario- based management and describe the integration of scenarios into process of strategic management. This includes specific methodological approaches to identify the key factors and logics for scenario building, to develop new strategies.

The purposes of this study is to identify the critical success factors for the 4th industrial revolution through literature review and to empirically evaluate the validity of these factors through questionnaires from executives engaging in the industries of the 4th industrial revolution. Literature review identifies leadership, change management, top management support, strategic fit, training, empowerment, teamwork, organizational culture, communication, and project management as ten critical success factors, Questionnaires were administered to CIOs and CEOs in the industries belong to the 4th industrial revolution. Response rate was 64.4% which shows quite high participation. Respondents rated strategic fit as the most important factor, followed by top management support, leadership, change management, project management, teamwork, communication, training, organizational culture, and empowerment. To successfully pursue the 4th industrial revolution, the followings are recommended. (1) detailed and refined execution strategy, (2) establishment of effective network among government, public companies, research institutes, universities, and industries, (3) strategic and long-term plan, (4) differentiated execution strategy from other countries and global cooperation system.

VTM is regarded as a core element in e-Navigation under developing by IMO. IMO's e-Navigation aims for VTM which could provide more navigational information for ships and provide more active VTS services for safe and efficient marine traffic environment. To be successful for VTM under e-Navigation, VTS operator's experience and ability for carrying out VTM tasks are essential. In this study, Decision-making support system for VTS operators are designed conceptually which support VTS operators' VTM tasks by providing informations on traffic risk, and predicted behaviour of ships. This paper describes a designed system with design concept, main functions, main elements and necessary technologies to be developed.

With the rise of the interest in a renewable system, the importance of the Life Cycle Cost Analysis(LCCA), an economic evaluation tool, has been increasing. However, there is an inevitable gap between a real cost and an estimation from LCCA because of the uncertainty of the external environment in real world. As the input variables in an analysis, such as a real discount rate and an energy cost, ares subject to change as time goes by, strategic decision on the current operating system is made depending on the real cost. Current economic evaluation approaches have treated only the fluctuation of input variables without consideration of the flexibility in operation, which has consequently led to the impairment on the reliability of LCCA. Therefore, new approach needs to be proposed to consider both the uncertainty of input variables and operational flexibility. To address this issue, the application of the Real Option to LCCA is presented in this study. Through a case analysis of LCCA of a solar heating system, the limits and current status of LCCA are identified. As a result, quantitative presentation of strategic decisions has been added in the new approach to implement the traditional approach.

This study is empirically intended to put forward the modeling and process improvement measures for the SCM capability in small venture firms. The findings are summarized as follows. There were strategic alliance, technological development and centralization in the modeling of strategic planning for supply chain, not the least of which is strategic alliance, followed by centralization and technological development. There were routing scheduling, network integration and third party logistics outsourcing in decision making, not the least of which was network integration. There were customer service management, productivity management and quality management in management control, not the least of which was quality management. And there were order management choice, pricing demand, shipment delivery and customer management in transaction support system, not the least of which was order management choice. As for the above-mentioned findings, to maximize the SCM capability and operate the optimized process in small venture firms, the existing strategic alliances can optimize the quality management and stabilize the transaction support system through the network sharing and integration from the perspective of relevant organizational members' capability and process improvement. And the strategic linkage between firms can maximize the integrated capability of information system beyond the simple exchange relation between electronic data, achieving a differentiated competitive advantage. Consequently, the systematization and centralization for the maximization of SCM capability, including the infrastructure construction based on the system compatibility and reliability for information integration, should be preceded before the modeling of the integrated capability for optimum supply chain and the best process management in the smart era.

Recently, there has been an increasing need to expand the supply of renewable energy as a solution to greenhouse gas emissions. Therefore, as a measure to promote domestic renewable energy investment and gradual expansion, this study analyzed the investment value of renewable energy projects utilizing the unoccupied spaces of public enterprise's facilities and presented a strategic decision-making framework to support efficient national land development and government measures. The NPV was estimated to be 286 million won if the expansion of the facility was not considered, but it is reasonable to postpone the expansion decision because the value of -130 million won was calculated if the expansion was considered. On the other hand, the real-option value was estimated to be 444 million won, taking SMP uncertainty, expansion, and abandonment options into account, and an additional value of 288 million won was calculated from an analysis of the expansion project using the existing NPV analysis.
