In case of developing a combined system by a number of distributed resources with storage device, a number of application suggests a huge capacity can derive operational flexibility both power supply issues or when unexpected situation imposed. However, it is important to determine a resonable energy capacity because the device have many controversial cost issues in current power system industry. An ESS application which focusing essentially required points can induce appropriate storage capacity that required in economic operation. In this paper, a curtailment supporting algorithm based on storage device is introduced, and applied in the capacity calculation method. The main algorithm pursues handling minor exceeding quantities which can cause mechanical load at blade; This paper tries to include it for configuring hybrid algorithm with pitch control. Several fluctuating conditions are utilized in simulation to reflect critical situation. The analyzing process focuses on the control feasibility with applied capacity and control method.

There is difference between European Cuisine and Korean Cuisine in various ways. In order to advance Korean Food into European Market, we should understand well European food-culture and food-custom. There are several process for push into the European Market. First, we inform European like that Korea traditional food (repast tool, the interior of Korean restaurant, traditional music, food-sequence, service method etc.). Second, we can introduce them ' Korean Fusion Food ' and that Korean Cuisine is ' Health foods '. For globalization of Korean Cuisine, we must understand exactly European market situation and know well the field law and tax system for business. Next, we establish the prior plan to supply with Korean food material till faraway region.

However, the mechanism for producing revised estimate is the principal means of varying the resulting precisions of estimate. Therefore, a scheduling system including physician's revision should be checked by a computer simulation to evaluate possible gains to admissions scheduling accruing from the use of these estimates. The ability to accurately predict bed occupancy has long been an objective of hospital management. If the one were able to anticipate bed accupancy, then the one could more accurately plan for bed needs, schedule personnel, allocate service and supply. We may conclude that even though the Markov chain analysis would not lead to ready-made answers for the scheduling system of elective patients, it can provide the more detailed and systematic knowledgy for the solutions on the weekly base as well as the foundations for long run planning in relative sense.

The fossil fuel has been used as the main resource of national development. Through this process, many environmental problems have happened. For example, we depend 97% energy on import for national spending and the exhaustion of the fossil fuel is at an important issue nowadays. So more people are interested in renewable energy which is more environmental and never be gone. However, the supply doesn't go on smoothly because of some problems such as capital condition, the limitation of geographical features and low technology, etc. In conclusion I'd like to check some policies and support systems about renewable energy first, and then to find problems for adapting other area through the comparison in this thesis.

Every effort is now being exerted in industrialized and developing countries to reduce emission of greenhouse gases from electric power sector. In this paper, we provide supply-side resource mix strategies in the long-term generation expansion planning under the expected greenhouse gas regulations. Under the environmental regulations, we explore the least-cost generation expansion plan of Korea and determine the composition of future resource mixes. Our analysis is performed on the basis of the revised WASP package which can evaluate emission of carbon dioxide from each power plant. The evaluation process of carbon dioxide emissions, which can consider the efficiency and operating conditions of each generator simultaneously, has been incorporated into the probabilistic production cost simulation module of WASP.

The related industrial technologies are also being developed in medicine, education, the military, transportation, process management, security management and information technology industries due to a rapid progress in telecommunications technology. The supervisory remote control system is based upon telecommunications technology. The supervisory remote control systems are used in various ways such as city gas, water supply and drainage, environment, power, communication and device control fields. The supervisory remort control system became a solution with complex systems and important technologies in electricity, city gas filed that require safety management skills. The supervisory remote control system as a special technology has a lot of practical applications. In this paper, Let me examine the present status of remort control system applications and present development plans and alternatives in city-gas industrial technology.

This paper evaluates the reliability of KEPCO system using TRELSS, which is a probabilistic reliability evaluation program for large-scaled power system. In order to reflect the characteristic of KEPCO system, the sensitivity of reliability indices such as LOLP, EDLC, EENS and Energy Curtailment for variations of TRELSS parameter and input data was analyzed. Additionally, probabilistic reliability of KEPCO system reflecting sensitivity analysis results was systematically evaluated and simulated. Finally, maximum acceptable FOR of KEPCO system to satisfy reliability criterion, which meet in process of establishing the basic plan for long-term electricity supply and demand is suggested.

The company cannot optimize its computing environment just with individual solutions such as ERP(enterprise resource planning), SCM(supply chain management), CRM(customer relationship management), and KM(knowledge management). EAI(enterprise application integration) has emerged as an alternative that can optimize computing environment of the company through integrating such solutions and systems of distributed computing and mainframe environment. This paper reports the case study of Deakyo Co. in successfully implementing EAI. It describes project goal, project organization, project plan, the implemented EAI configuration and its features, the EAI effectiveness to the firm, and the critical success factors of the EAI project. This case study is thought to be useful as a practical guideline in carrying out EAI project of the company and to provide significant basis for constructing the theoretical framework of EAI project methodology.

최근 들어 기업의 외부 환경은 글로벌 경쟁, 원가 절감과 이윤 확보에 대한 압박 및 신기술의 급격한 발전 등에 의해 매우 급속하게 변화하고 있다. 특히, 고객 요구 사항의 빈번한 변화는 제조 기업에게 심각한 도전이 되고 있다. 이러한 도전에 대응하기 위해서는, 고객 서비스 향상과 운영 효율성 제고를 위해 여러 관리 기능 중에서 생산계획 기능이 우선적으로 정립되어야 한다. 생산계획은 전체 공급망 관리 중에서 생산 프로세스에서의 단기적 의사결정을 다루며, 그 역할은 고객 주문과 제한된 자원 사이에서 균형을 찾는 것이다. 본 논문의 목적은 공급망 관리 관점에서 생산계획의 기능성과 시스템 아키텍처를 분석하고, 이를 기반으로 생산계획 솔루션들 간의 비교를 가능케 하기 위한 분류 프레임워크를 제시하는 것이다.

스마트 공장의 생산 계획 및 제조 데이터를 이용하여 AI 기반의 효율적인 재고 관리 및 물류 최적화 기술을 적용하면 해당 제조 기업의 생산성 향상과 고객 만족도 향상을 기대할 수 있다. 본 논문에서는 공장의 생산 공정에서부터 데이터를 수집하여 클라우드에 저장하고, 여기에 저장된 제조 데이터를 활용하여 추후 AI 기반의 공급망 최적화 기술을 적용할 수 있는 시스템을 제안하였다. 기존 시스템의 경우는 대략 10종~20종 정도의 데이터 타입을 지원했다면, 제안 시스템은 100종 이상의 데이터 타입을 지원하도록 설계 및 개발된다. 또한 수집 주기의 경우는 매 초당 1~2회의 데이터를 수집할 수 있도록 지원하며, TB 단위의 데이터 수집이 가능하다. 따라서 본 시스템은 자동화된 데이터 수집 체계를 갖추고 있는 스마트 공장 외에 기존의 전통 제조 현장에도 적용할 수 있도록 고안하였다.
