Integrated Flood Control System for HAN River Basin
Shim, Soon-Bo,Shim, Kyu-Cheoul,Fontane, Darrell G.,Labadie, John W. 충북대학교 건설기술연구소 2004 建設技術論文集 Vol.23 No.1
본 논문은 공간의사결정지원시스템의 시범시스템으로서, 다목적 저수지군의 실시간 통합유역홍수조절 시스템에 대한 연구이다. 본 공간의사결정지원시스템은 자료관리시스템, 실시간 기상 및 수문자료 모니터링시스템, 저수지군의 모의 및 최적화를 모형기반시스템, 시스템의 효율적인 사용을 위한 사용자편의시스템으로 구성되어 있다. 홍수사상 동안에 수시로 갱신되는 홍수 수문자료의 공간적인 분포를 예측하여 제공하기 위하며, 신경망 알고리즘이 사용되었다. 예측자료는 유역 저수지군의 게이트조절을 위한 최적화 전략수립을 위한 입력자료로서 활용된다. 본 시스템은 1995년 한강유역의 홍수사상에 적용되었으며, 하류의 홍수피해를 최소화하면서 홍수기 이후의 수자원확보를 최대화할 수 있는 운영률을 제시하였다. A prototype spatial decision support system (SDSS) is presented for integrated, real-time river basin food control in a multipurpose, multireservoir system. The SDSS integrates a GIS with a database management subsystem, a real-time meteorological and hydrological data monitoring system, a model-base subsystem for system simulation and optimization, and a graphical dialog interface allowing effective use by system operators. The model-base subsystem employs an artificial neural network in a real-time flood forecasting module providing spatially distributed forecasted flows that are updated as the flood event progresses. Forecasted, basin-wide discharges are input into a dynamic programming module providing optimal gate control strategies, which are also updated in real-time. The SDSS for flood control is applied to the Han River Basin in Korea and demonstrated through simulated application to a severe 1995 flood event. Results of the case study indicate that integrated operational strategies generated by the SDSS for flood control substantially reduce downstream flood impacts, while maintaining sufficient conservation storage for water use subsequent to the flood seas.

하이브리드 전문가시스템 개념에 의한 충주 및 소양강 다목적댐의 연계운영을 위한 사용자중심의 GUI 개발
심순보,김만식,고덕구,--,심규철 한국전문가시스템학회 1995 학술대회 Vol.1 No.1
In order to utilize the limited water resources, it is strongly desired to develop a system for optimal operation of the multipurpose reservoir system easily with visualization of inflow, storage, release, and etc. However, in the water resources management problem, the user of reservoir operation models is often trapped in an ambiguous situation because not only are most reservoir operation models very complex but also building their data is not so easy. However, this difficult problem may be approached using concepts of artificial intelligence. Expert systems, one branch of artificial intelligent programming, is used as an interface between the user and models. This fancy user interface help the user to build the data using the database, run the models, analyze the results and decide on the optimal operation rules for the reservoir operation problem. Moreover, the hybrid expert system, one concept of the expert system, lets us make the user interface easily without changing or converting the algorithmic models into an expert system programming language. Using the above concepts, a user friendly Graphical User Interface (GUI) for the Chungju, Soyang, and joint operation for the both reservoir has been developed. Not only 261 optimal operation rules but also 261 judgmental rules or heuristics for the Chungju reservoir have been collected and developed by the CJDP model. For the verification and validation of the developed GUI, a case study in Chungju Reservoir has been described. In this study, the overall concept and implementation of the hybrid expert system are described.

Resumen. Se estudia el régimen autoritario imperante en Chile luego del golpe de Estado de 1973, centrándose en su estructura político institucional. Al respecto, se aborda una problemática en discusión a nivel académico: la naturaleza personalizada o colegiada de la conducción del régimen y su relación con el proceso de institucionalización que lo caracteriza, que comprendió la aprobación electoral de la Constitución de 1980. Se consideran críticamente los aportes de autores con perspectivas enfrentadas, con la intención de avanzar en la conformación de una conceptualización comprehensiva. El régimen contó con una conformación original colegiada por parte de las “Fuerzas de Defensa Nacional”, pero prontamente, en un proceso paralelo a la ampliación de sus objetivos rectores, quedó sujeto a los vaivenes de una puja entre dos fuerzas: Pinochet emprendió un esfuerzo por concentrar y personalizar la conducción, mientras que los mandos de los restantes cuerpos buscaron preservar cuanto fuera posible la conformación plural original, desarrollando mecanismos de distribución de poder que les permitieran ejercer cierto control sobre la toma de decisiones. La resolución progresiva de esta puja estuvo, a su vez, estrechamente vinculada con el proceso de institucionalización, resultando en una estructura compleja que fue consolidada en la Constitución de 1980. Abstract. This paper examines the institutional and political structure of the Chilean military regime (1973-1990), with particular focus on an issue still under discussion within the academic community: the personalized or collegial nature of its decision-making and its relationship with the institutionalization process which involved the electoral approval of the 1980 Constitution. Palabras Clave: Régimen militar de Chile, Augusto Pinochet, Junta militar de gobierno, institucionalización, Constitución de 1980. Key words: Chilean military regime, Augusto Pinochet, Military junta, institutionalization, 1980’s constitution.
