  • 수자원시스템의 효율적인 운영 및 관리를 위해서는 하천 시설물들을 효율적으로 연계운영 할 필요가 있다. 그러나 이를 위한 시뮬레이션 모형은 최선의 대안을 보장하지 못하고, 최적화 모형은 복잡한 수계 현황을 유연하게 고려하는데 어려움이 있다. 따라서 시뮬레이션과 최적화 기법의 한계점을 서로 보완해서 활용하는 것이 바람직하다. 이에 본 연구에서는 시뮬레이션과 최적화 기법의 원론적 비교를 통해 각 기법의 장 단점을 분석하고, 두 방법의 한계점을 극복할 수 있는 시뮬레이션 기반의 최적화 모형, CoWMOM의 활용을 제안한다. 아울러 댐-보 연계운영 모형의 활용방안으로 i) 과거의 특정 기간에 대한 분석 도구로써의 활용법과, ii) 미래 수문 정보가 불확실한 상황에서 댐-보 연계운영을 하는 현실에 적합한 모형 활용 절차를 제시한다.

  • The Project of Jordan Research and Training Reactor (JRTR) officially launched in Aug. 2010. JRTR is the first made-in-Korea nuclear system to be built abroad by year 2015, and Korea Atomic Energy Research Institute (KAERI) is responsible for the design of major systems including the reactor core. While the PDCS (Project Document Control System) being operated by EPC company controls all the documents of the whole Project, KAERI is supposed to have its own system for KAERI documents. Meeting such a need; KAERI has implemented a document control for the JRTR Project into already existing ANSIM (KAERI Advanced Nuclear Safety Information Management) system. The documents of JRTR project to be controlled are defined in the PPM (Project Procedures Manual), QAP (Quality Assurance Procedure) and PEP (Project Execution Program). The ANSIM consists of the document management holder, document container holder and organization management holder. The document management holder, which is the most important part of ANSIM-JRTR, consists of the DDA (Document Distribution for Agreement), IOC (Inter-office Correspondence), PM Memo. (Project Manager Memorandum) and cover sheets of design documents. Other materials such as meeting minutes, sub-department materials and design information materials are stored in an independent COP (Community of Practice). This established computerized document control system, ANSIM, could lessen a burden for project management team and enhance the productivity as well.

  • The purpose of this study is to understand the phenomenon of agricultural management transfer and to present a plan to activate Korean management transfer through institutional consideration. To this end, the domestic and overseas agricultural management transfer system was identified, and an appropriate institutional plan for the country was sought. There are six ways to activate the management transfer system proposed in this study. First, establishment of an agricultural management transfer agency, second, training and utilization of management transfer experts, third, establishment of an agricultural succession certification support institution, fourth, operation of specialized training courses for management transfer, fifth, (local government) linked operation of a farming support center, sixth, agricultural management transfer legislation and securing of budgets. The above agricultural management transfer system is expected to contribute to the advancement of management transfer activation.

  • The purpose of the study was to make an improvement of residential management regulations so that the inhabitants of rental housing can manage their housing in efficient and transparent manners by comparing and analyzing in standard management rules of rental housing. The research method were as follows: 1) The analysis framework utilized result of preceding research composed 6 types of management works and 36 items of subcategories by researcher 2) The standard management rules of rental housing used analysis utilized to draw up after a revision of Rental Housing Act in 2000 and to operate in management of rental housing now. 3) The analysis method used content analysis. The management rules of rental housing utilized a total of 5 rules such as management rules of SH corporation (2011), LH corporation (2000), peoples' solidarity for participatory democracy (2000), Citizens' Alliance (2000) and Gyeonggi-do (2001). The research result were as follows: 1) Overall, the management rules of rental housing included faithfully works of operation management and administration management 2) The type of operation management regulated centrally items related resident committee. and The type of administration management regulated centrally items related accounting management. 3) The management rules of SH corporation and LH corporation regulated centrally operation management, maintenance management and etiquette for the basic living as compared with the other rules.

  • An Automated Guided Vehicle System (AGVS) with a unidirectional loop guide path is modeled as a discrete-time stationary Markov chain. It is discussed how to estimate the mean response time, the utilization, and the cycle time of AGV for a delivery order. Three common operation strategies for idle vehicles - central zone positioning rule, circulatory loop positioning rule and point of release positioning rule - are analyzed. These different operation strategies are compared with each other based on the performance measures.

  • The evaluation test for the operation of rotary type surface mounters which consist of the reel axis, the index table and the X-Y table, has been performed by comparing the new method with the old one in only fields. Because the problem seeking for the optimal operation of rotary type surface mounters, is NP complete, it is almost impossible to get the optimal solutions of large problems. This paper deals with a dynamic network modeling, which can reduce the effort, the cost, and the time used for the performance test of rotary type surface mounters.

  • We propose a framework for modelling and operation management of robotic assembly cells via knowledge base. In the framework, each component of the cell is considered as a state variable, the relations among the state variables are stored in state transition maps(STMs) and then transformed into the form of knowledge. The assembly job tree(AJT) which includes the precedence relations and the constraints for assembly tasks is also described. Finally, an algorithm is presented to manage the cell operation.
