본 연구는 선행연구에서 제시된 ERP시스템의 운영단계의 성공요인들에 대해서 전문가 그룹의 면담과 의견 수렴과정을 거쳐 중요 핵심 성공요인을 도출하고, 도출된 성공요인들을 계층화 의사결정법(AHP)을 이용하여 각 요인들에 대한 상대적인 중요도를 분석하였다. 1차 계층의 성공 요인들에 대한 중요도 분석에서는 조직/인력 요인의 중요도가 가장 높은 것으로 나타났으며, 2차 계층의 성공요인을 1차 계층의 중요도를 고려한 가중치 분석에서는 경영진의 지원과 관심이 가장 중요한 요인으로 분석되었고, 그 다음으로 프로세스 최적화, 변화관리, 운영조직의 지원, 프로세스 혁신조직 유지 순으로 분석되었다. 따라서 본 연구에서는 ERP 시스템의 운영단계에서 ERP 시스템의 도입 성과를 극대화하기 위해서는 경영진의 지속적인 지원과 관심뿐만 아니라 ERP 시스템의 도입으로 인한 내부 환경 변화에 대한 적절한 변화관리가 요구되며, ERP 시스템을 전담하는 운영조직의 지원과 프로세스에 대한 지속적인 혁신을 위한 별도의 조직을 갖추어야 할 것이라는 연구결과를 제시할 수 있었다.

It is high level of management activity for the fixed property of building to operating spaces for education in university campus. Therefore, this study is focused on definition of the factors for analyzing the actual conditions of space operation and application of them to C university campus in Gyeongbuk in the aspect of infrastructure of university and efficiency of space operation. These analytical factors are the rate of lecture and experimentation room, the rate of theoretical and experimental subject in curriculum and unit area for infrastructure and the rate of use, turnover rate and occupation rate per lecture for space operation. If the analytical factors of space operation are systemized as program module for space operation, the space management system of university campus will be characterized on the foundation of university information system. And it will be able to support the decision making about space management. It needs to integrate various type of information and data of university to increase the efficiency of decision making.

The number of unmanned light rail train operators is continuously increasing in Korea. In a failure event during an operation due to the nature of the unmanned operation, recovery is performed based on the remote control. However, if remote recovery is not feasible, safety personnel arrive at the train to resume the train operation. There are regulations on safety personnel and the suspension time of the train operation. However, there is currently no rule for safety personnel deployment. Currently, railway operating organizations operate in three scenarios: safety personnel on board trains, stationed at stations, and deployed at major stations. Four major factors influence the downtime for each emergency response scenario. However, these four influencing factors vary too much to predict results with simple calculations. In this study, four influencing factors were considered as random variables with high uncertainty. In addition, the Monte Carlo method was applied to each scenario for the safety personnel deployment to predict train service downtime. This study found a 17% difference in train service suspension by safety personnel deployment scenario. The results of this study can be used in setting service goals, such as standards for future safety personnel placement and frequency of service interruptions.

본 연구는 퍼지이론을 이용하여 신규 건설중인 인천항 신국제여객터미널의 항만운영 성공요인 도출을 연구의 목적으로 하였다. 항만운영 성공요인은 카페리선사와 항만하역사에 종사하는 임직원을 대상으로 1차적으로 설문조사를 진행한 후, 한중카페리 선사 및 해당 하역사의 근무경력 15년 이상 전문가와 심층인터뷰(Indepth-Interview)를 수행하여 최종적으로 선정하였다. 전문가의 지식 추출이 가능한 퍼지방법을 활용하여 성공적 항만운영 요인에 대한 가중치를 산정하였다. 신국제여객터미널을 이용하게 될 선사와 하역사들을 대상으로 "부지 사용적 측면", "생산성 측면", "비용적 측면", "항만서비스 측면"으로 상위평가요인을 분류하여 항만운영의 성공요인을 비교분석하였다. 분석결과 "부지사용적 측면"은 컨테이너장치장 확보(0.857)가 가장 중요한 요소로 나타났으며, "생산성 측면"에서는 터미널의 자동화 시스템 구축(0.806)이 가장 중요하게 분석되었다. "비용적 측면"과 "서비스적 측면"에서는 부지 임대료 산정(0.861)과 선석스케쥴 관리(0.798)가 각각 가장 중요한 요인으로 나타났다. 결론적으로 신국제여객터미널은 적정임대료 산정, CY장치장 적정면적 확보, 터미널의 자동화 시스템 구축 등에 주력하여 항만운영을 해야 한다는 시사점을 지니며 향후 동일 운영형태의 국제여객터미널 비교분석 연구를 진행할 필요성이 존재한다.

Gori-I nuclear power plant has been examining the effectiveness and efficiency of the current emergency operation procedures from human factors viewpoint. Previous study showed that some mistakes that the procedures did not comply with the writers' guidelines. Reviewing the current writers' guidelines for emergency operating procedures revealed that they lack of some important human factors rules such as enumeration of switching conditions and detailed action requirements, definite expression for setup points, description for anticipated results, and recommendation for use of present tense, affirmative sentence and active voice. This study suggested a new classification system for the writers' guideline contents supplementing the deficiencies of the current emergency operation procedure text.

The Purpose of this study is to improve the deterrent factors in Korea's coastal passenger shipping on the basis of field data collected in order to help stimulate it and enhance its competitiveness. As the representative model of this study, the "P" car-ferry liner was chosen, whereby various deterrent factors were observed in the course of the SWOT analysis and through the questionnaires. The major deterrent factors in summary were inflexible government regulations for additional ship operation, disadvantages of taxes policy, port facility shortages, non-allowing of ship's night operation, complicated and inflexible ship's operation controls by the concerned authorities, unreasonable divisions of steaming areas, and existences of obstacles on the ship's running routes, etc. which considered all are important to activate the liners.

This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.
