  • The traditional economic evaluation methods do not seem to consider derivative efforts-productivity improvement, quality improvement.-which may be occured by AMS introduction. Current evaluation methods are based on mass production with known characteristic and stable technology. Recently, expert suggest that these assumption-stable production and mass production-are realized to be a limited in substantial economic evaluation analysis. Therefore, the problem of traditional evaluation methods suggested in this thesis and decision in the case studies are derived using two complementary economic analysis methods-AHP method, modified economic evaluation model- and traditional evaluation method. After three methods are compared and evaluated in the view of practical economic evaluation, AHP method is intended to be introduced as a new economic evaluation method.

  • In this research, economic analysis of Integrated Information System for Nano-convergence Industy (hereafter 'NANOIN'), which was developed and has been in operation by Organization of Nano-convergence Industrial Cooperation, is conducted. For this purpose, the research has been carried out in the following order. First, NANOIN user's maximum willingness-to-pay is estimated using contingent valuation method, the number for NANOIN users is estimated using Bass Diffusion Model, and annual benefit from NANOIN is estimated. Next, annual cost from NANOIN is estimated using annual budget for NANOIN related planned activities. Finally, economic value of NANOIN is evaluated using economic analysis applied to the estimated annual NANOIN benefit and cost. From the economic analysis, it is found that NANOIN has some economic value. It is expected that the procedures suggested in this research can help to systematically evaluate economic value for public goods which have not only uncertain benefit from user's side but also uncertain demand just like NANOIN.

  • Since Cost Based Pool markets has been continued to power markets, Genco. needs economic analysis about investment in power plants. Particularly most Private Genco.s have presently a construction plan about LNG combined cycle thermal power plants. In this paper, we propose a economic analysis method of LNG combined cycle thermal power plants using Economic Dispatch and Optimal Power Flow in CBP markets. Also we develope computation model using it for decision making to build a plant. This method can consider a variation of power facility like power plants and transmission lines in CBP markets. Finally, this dissertation provides a relevant case study to confirm the effect of cost factor to economical efficiency.

  • RFID 확산이 어려운 이유 중 하나는 구체적 경제성 분석 방법의 부재라 할 수 있다. 기존 문헌 분석과 파급 효과가 큰 택배산업 사례를 통해 RFID 도입에 따른 비용/혜택 분석을 포함한 경제성 분석 방법을 제시하였다. RFID 적용 효과의 기대 수준을 낙관적, 보수적, 비관적으로 정의하여 분석하고, 태그 단가 등에 따른 민감도 분석을 통해 RFID 비용과 RFID 기술 기대 수준에 따른 불확실성을 반영하였다. 본 연구의 결과는 RFID 도입을 위한 의사결정에 기여할 수 있을 것으로 예상된다.

  • Purpose: The government around the world is still highlighting the effect of the new variant of Covid-19. The government continues to make efforts to restore the economy through several programs, one of them is National Economic Recovery. This program is expected to increase public and investor confidence in handling Covid-19. This study aims to capture public sentiment on the economic growth rate in Indonesia, especially during the third wave of the omicron variant of the covid-19 virus, that is at the time in the fourth quarter of 2021. Research design, data, and methodology: The approach used in this research is to collect crowdsourcing data from twitter, in the range of 1st to 10th October 2021. The analysis is done by building model using Deep Learning Neural Network method. Results: The result of the sentiment analysis is that most of the tweets have a neutral sentiment on the Economic Growth discussion. Several central figures who discussed were Minister of Coordinating for the Economy of Indonesia, Minister of State-Owned Enterprises. Conclusions: Data from social media can be used by the government to capture public responses, especially public sentiment regarding economic growth. This can be used by policy makers, for example entrepreneurs to anticipate economic movements under certain conditions.

  • 경제성 분석에 의한 재무타당성 분석은 이론적으로나 실무적으로 그 타당성이 인정되고 있으나, 할인율 추정이 어려운 관계로 경제성 분석과 결과해석이 실무적으로 쉽지 않다. 따라서 본 연구는 신규호텔 건설 시 경제성 분석에 의한 재무타당성 분석의 구체적인 틀과 실무적용방법 및 기술을 제시하는데 근본적인 목적을 두고 연구하였다. 연구의 결과, 첫째, 대용베타방식에 의한 할인율(자본비용)을 실무적으로 추정하는 방식을 제시하여 경제성 분석결과에 대한 신뢰성과 타당성을 증대시킬 수 있었다. 둘째, 할인율과 현금흐름을 이용한 경제성 분석기법(순현가법, 내부수익율법, 수익성지수법 등)에 의한 재무타당성 분석의 전체적인 틀을 설명할 수 있었다. 셋째, 재무타당성 분석의 각 단계에서 요구되는 실무적인 분석기술을 제시할 수 있었다.

  • 태양열 주택 및 급탕의 보급 정책은 민수용 에너지의 절감 또는 대체의 의미에서 그 필요성 및 당위성을 인정받고 있으나, 다른 대체에너지와 마찬가지로 태양열 이용시스템의 경제성이 가상 문제가 되고 있는 실정이다. 본 연구에서는 태양열 주택 및 급탕의 경제성을 상세히 분석함으로써 실질적인 보급정책 자료를 제공하며, 실수요자를 위한 계몽근거를 마련하고자 한다. 본 연구에서는 태양열 이용시스템의 경제성을 정확히 수행하기 위한 의사결정지원 시스템(decision support system)을 확립시켰으며, 이에 따른 태양열 이용시스템의 열적성능 해석과 동시에 경제성 분석은 시행오차(trial & error)하에 수행할 수 있도록 각종전산 프로그램을 개발하였다. 태양열 주택 및 급탕의 열적성능 해석은 모의실험을 통하여 기상 조건과의 상관관계를 도출하고 태양열 이용시스템의 추가비용 및 연료가 이용을 현재가 (present worth) 개념으로 적응하여 산출하고, 순익분기 해석법 (break-even point analysis method) 및 수명가 산정법(life-cycle cost analysis method)으로 경제성 분식을 중점적으로 수행하였다.

  • Today, the power utilities is setting on the slow load growth and the aging of power equipment, and then could spend the efforts on the stability of system performance. Asset management may be defined as the process of maximizing corporate profit by maximizing performance and minimizing cost over the entire life cycle of power equipment. Therefore, asset management is great way to fulfill the economic investment and the stability of system performance. This paper presents the application of effective asset managem ent from an economic perspective. A proposed method is considering the life cycle analysis using life cycle cost methodology for hydro-generator during the total life cycle. The life cycle cost methodology include a way to calculating maintenance and operating costs. The proposed method will be expected to play an important role in investment decision making considering economic evaluation.
