The objective of this study is to review the methodology of economic analysis of fishing ports by examining the economical feasibilities of a national fishing port (Jeongja Port) in Ulsan. This study utilized market value evaluation method to measure the benefits and costs related to the development of ports. The benefit variables are income effects resulting from the developments while the cost variables are sum of construction costs and maintenance costs. The income effects are measured in two ways: (1) income from individual project resulting from the developments, (2) the income effects by utilizing investment multipliers. The results shows that the BC ratio (Benefits/Costs) of Jeongja port by using (1) income from individual project resulting from the developments was 1.07 while the BC ratio by using (2) the income effects by utilizing investment multipliers was 1.10 due to a relative short period of useful life for investment multipliers. However, the income variable utilizing investment multipliers is more sensitive to the period of duration than the income variable from individual project.

As the electric power market environments are being changed, suitable data for expansions should be subjected to stockholders. And the public responses are requested for transmission system expansion. The necessity of transmission system expansion can be easily assessed via the benefit/cost evaluations. Because the benefit/cost evaluation of the transmission system expansions required variety elements, which can be depended on electric power market simulation software. On this paper, a method is illustrated using the PPOOL developed by PPC and PSS/E developed by PTI.

A Cost-Benefit Analysis which would help us to make optical decisions among safety investment alternatives, calculating and comparing costs and benefits for facilities in chemical plants. As well as offering the related information in the decision makings for safety improvement, it promotes on-site safety activities and the efficiency of safety investments The developed Cost-Benefit Analysis will eventually contribute to our efforts in economically justifying the safety investments in chemical plants.

An optimal selection problem of SCM system is one of the critical issues for the company's competitiveness and performance under global economy. This paper presents a hierarchy model consisted of characteristic factors for introducing SCM system and an AHP (Analytic Hierarchy Process) based decision-making model for SCM system evaluation and selection. The proposed model can systematically construct the objectives of SCM system selection to meet the business goals. This paper focuses on selecting an optimal SCM system considering both all decision factors and sub-decision factors of a hierarchy model. Especially, the benefit/cost analysis is applied to choose SCM system. A case study shows the feasibility of the proposed model and the model can help a company to make better decision-making in the SCM system selection problem.

This paper has shown that Linear Induction Motor(LIM) and Rack and pinion type are efficient in selecting railway routes and systems after considering time, geo-spatial characteristics and the floating population by benchmarking domestic and overseas mountain trains. The benefit-cost analysis through the use of modeling on user's willingness to pay is conducted as a means that provides access to tourism resources. this paper concludes that the benefit-cost varies in response to changes in the amount of user's willingness to pay by age. It is expected that this paper serves as a reference data in the introduction stage of the mountain train project implemented by central or local governments with tourism resources in mountainous areas as the mountain train has turned out to be economically efficient while various potential benefits that have not been included in the benefit-cost analysis need to be quantified and remain to be studied further.

A study on environmental noise hasn't fully researched yet. As society has developed and the quality of life has improved, people started to show a concern about an environmental noise. To ensure a economic feasibility of countermeasures of noise, it is necessary to apply a cost-benefit analysis on choosing optimum measurements. In this study, we addressed the estimation method of the environmental noise value and several domestic and oversea case studies. We also estimate economic value of noise reduction level which is gained from applying noise reduction measurements.

Railway is superior to the other land transportation systems in aspects of environmental problems. Environmental problems are not considered during a preliminary feasibility study. Investment for railway is low because of low B/C(benefit/cost)ratio in the economical efficiency analysis during the preliminary feasibility study. The body of this paper studies the railway noise which can reflect environmental problems an assessment of environmental impact. The body of this paper studies the presumption of The Benefit Cost of railroad noise arresting it will be able to reflect the evaluation environmental matter of the effect which it gives to an environment.

This paper proposes that the Marine Search & Rescue and Salvage Association of Korea (MARSA) can provide KCG a very positive return on investment; that is, MARSA will save lives and property well over the budget needed from KCG to operate MARSA. To perform this Cost-Benefit Analysis, actual performance data and other figures are taken from the USCG Auxiliary, and these figures are used to project expected possible MARSA results. In this paper, MARSA is projected to provide a 1,493 % return on investment.

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.
