The imports of used medical equipment such as CT. MRI have been rapidly increased every year. How to manage those medical equipment has been one of critical issues in the government sector. In this study, we demonstrate how benefit/cost analysis using the Analytic Hierarchy Process (AHP) can be applied to the comparison of used CT/MRI and new CT/MRI. The final results show that the new CT/MRI is more attractive than the used CT/MRI.

This paper presents the economic validity with the cost/benefit analysis on establishing R&D Supreme Academy. To evaluate the profitability of R&D Supreme Academy, willingness to pay (WTP) is measured by contingent valuation method (CVM) and then the net present value (NPV), internal rate of return (IRR) and benefit/cost ratio(BCR) are calculated. The results of economic evaluation verified that the establishment of R&D Supreme Academy is timely and effective in an economic perspective.

This paper presents an approach to quantifying the costs and benefits of integrating ERP systems with project management systems, including potential time and cost savings. To properly identify the costs and the benefits, the paper shows the relevant construction information flows and the desired milestones in the integration process. The proposed benefit analysis model should allow construction firms considering the integration of their ERP systems with legacy systems or commercial project management software make informed decisions in regard to the existing alternatives in the early stages of decision making.

본 연구는 장애인차별금지법의 제정으로 장애인 차별이 해소될 경우에 대한 잠재적 비용과 편익을 추정함으로써 장애인차별금지법 제정에 도움을 주고자 하는 목적으로 시도되었다. 장애인차별금지법 제정으로 인한 잠재적 편익은 장애인 추가 고용으로 인한 장애인의 소득 증대, 사업주의 고용부담금 감소, 공공부조성 급여의 감소를 중심으로 추정하였으며, 비용은 장애인을 고용함으로써 사업주가 특별히 투자해야 할 비용과 차별시정기구 운영비를 중심으로 추정하였다. 추정 결과 7%의 할인율 하에서 얻게 되는 순현재가치는 12,700,301백만원으로 매우 크게 나타났으며 비용-편익비는 96.8로 역시 매우 크게 나타났다. 할인율을 변화시켜 민감도 분석을 한 결과도 큰 변화가 없었다. 이와 같은 추정 결과 장애인차별금지법이 제정되어 차별이 해소될 경우 사회의 잠재적 순편익은 매우 크다는 것을 알 수 있었다. 결국 장애인차별금지법 제정의 필요성이 강조된다고 할 수 있다.

Purpose: This study purposed to analyze the economic feasibility of introducing a third party logistics system as a strategic alternative to hospital management. Methods: Economic analysis was performed by measuring changes in costs and benefits before and after implement the third party logistics system and estimating the size of net benefits for the next five years for the target hospital. A questionnaire survey and in-depth interview with stake-holders were conducted to find out the satisfaction and effectiveness of the system. Findings: According to results, the cost-benefit ratio for the implementation of the system was 1.18. For the next five years, the cost-benefit ratio was 1.48, the net present value was about 1.7 billion won, and the internal rate of return was 64%. The satisfaction of internal stake-holders was relatively high, in terms of improving the concentration of unique tasks and increasing the efficiency of inventory management. Practical Implications: It was found that the increase in benefits had a greater effect on the change in the cost-benefit ratio than the increase in costs resulting from the expansion of logistics, and the increase in the present value of net benefits gradually decreased as the cost increased. In addition, overall job satisfaction and satisfaction with outsourcing companies were relatively low, which means that stabilization of the new system is important. Further study is needed for more accurate economic analysis.

Recently, interest in the DC transmission is rapidly increasing worldwide. In many countries and leading companies are prior to the aggressive development of HVDC technology and application. Especially, VSC-HVDC system has been widely applied to transfer power at long distance between power plant and power consumption area. Therefore in this paper, we analyzed the benefit-cost of VSC-HVDC system which has more advantages than existing transmission system. The proposed system is MMC(Modular Multilevel Converter) VSC-HVDC system that have stability of Power Grid, interconnect Large-scale New Power Generation Plants by prevents Blackout. And MMC VSC-HVDC system Reduced the loss importing foreign systems. And the benefits were calculated in four stages, and the costs were applied to the actual project. By evaluating the various avoidance costs compared to the benefit-cost, it was confirmed that MMC VSC-HVDC system was advantageous in system stability and economic and social benefits.

Recently, various energy efficiency optimization activities are ongoing globally by integrating conventional grids with ICT (Information and Communication Technology). In this sense, various smart grid projects, which power suppliers and consumers exchange useful informations bilaterally in real time, have been being carried out. The electric vehicle diffusion program is one of the projects and it has been spotlighted because it could resolve green gas problem, fuel economy and tightening environmental regulations. In this paper, the economics of V2G system which consists of electric vehicles and the charging infrastructure is evaluated comparing electric vehicles for V2G with common electric vehicles. Additional benefits of V2G are analyzed in the viewpoint of load leveling, frequency regulation and operation reserve. To find this benefit, electricity sales is modeled mathematically considering depth of discharge, maximum capacity reduction, etc. Benefit and cost analysis methods with the modeling are proposed to decide whether the introduction of V2G systems. Additionally, the methods will contribute to derive the future production and the unit cost of electric vehicle and battery and to get the technical and economic analysis.

This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.

본 연구에서는 개발 중인 초음파 기술을 적용한 태양광발전설비 세척 장치의 경제성 분석을 위하여 AHP 편익-비용을 분석하였다. 초음파 기술을 적용한 태양광발전설비 세척장치와 유사한 특성을 가지며, 국내에서 널리 사용되고 있는 태양광발전설비 세척 장치를 비교 대상으로 선정하여 상대적인 편익-비용 분석 값을 비교하였다. 두 비교 대상의 편익, 비용을 정량적, 정성적으로 분석하기 위하여 각각의 측면의 상위계층과 하위평가항목을 도출하고, 하위 평가항목에 대한 평가기준을 도출하였다. 도출된 평가기준을 기반으로 15인의 전문가 인터뷰를 수행함으로써 두 비교 대상의 편익, 비용 가중치를 계산하였다. 분석 결과, 초음파를 사용한 태양광발전설비의 편익-비용 분석 값은 1이상으로 비용대비 이익이 더 높을 것으로 예상되었고, 비교 대상의 편익-비용 분석 값보다 약 1.6배 높았다. 이는 경제적인 측면에서 초음파를 적용한 태양광발전설비 세척 장치의 개발 가치가 있다는 것은 의미한다.
