  • 공학적 투자사업을 선택하거나 기각하는 의사결정기준으로 내부수익률법이 널리 사용되고 있다. 그러나 투자사업에서 예상되는 현금흐름의 형태에 따라 다수의 내부수익률이 존재하는 상황이 발생하면 내부수익률법은 의사결정기준으로 사용하기에 부적합하다. 내부수익률의 이런 문제를 해결하기 위하여 전체 수익률 또는 외부수익률을 의사결정기준으로 사용할 수 있다. 그러나 외부수익률도 다양한 방법으로 정의되어 의사결정기준으로 적합한 외부수익률 계산방법을 정해야 하는 문제가 있다. 따라서 공학적 투자사업의 의사결정기준으로 적합한 외부수익률의 조건을 순현재가 치법과 비교하여 탐색한다.

  • 투자안 가치평가 방법에는 화폐의 시간가치를 고려한 방법과 고려하지 않는 방법이 있다. 이중 가장 많이 쓰이고, 중요한 방법으로는 화폐의 시간 가치를 고려한 순현재가치법(NPV), 내부수익률법(IRR), 수익성지표법(Pl)등이 있다. 이중에서도 우리는 투자사업으로부터 사업의 최종년도까지 얻게 되는 순이익(수익-비용)의 흐름을 현재가치로 계산하는NPV 분석을 많이 실시하고 있다. 즉, 어떤 자산의 NPV가 0보다 크면 투자 시 기업가치의 순증가가 발생하므로 투자가치가 있는 것으로 평가하고 0보다 작으면 기업가치의 순감소가 발생하므로 투자가치가 없는 것으로 평가한다. 여기에서 많은 기업경영자 및 재무담당자들은 다음과 같은 의문을 갖고 NPV분석의 약점을 보안할 필요성을 제기하고 있다. “결과로부터 얻은 단일 값이 정말 신뢰할 만한 값인가?”, “만약 몇 가지의 리스크 요인이 우리의 사업모델에 영향을 미친다면 그 결과는 어떻게 달라질 것인가?”, “우리가 얻은 결과 값의 실현 가능성은 몇%이고 나머지 발생 가능한 값들의 분포는 어떻게 될 것인가?” 위 질문에 대한 답을 얻을 수 있다면 투자안에 대해 빠르고 올바른 의사결정을 내릴 수 있으며 실패의 위험을 줄일 수 있다 이런 분석을 가능하게 해 주는 것이 확률론적 분석이며, 즉 몬테카를로 시뮬레이션 기법이다. 이미 많은 선진 기업에서 이 방법을 통하여 모든 의사결정에 중요한 참고 자료로 이용하고 있으며 본 논문은 몬테카를로 분석의 대표적인 소프트웨어인 Crystal Ball을 이용하여 그 활용 사례를 소개하고자 한다.

  • It is evident that a financial feasibility study based on the economic analysis has been theoretically and practically accepted in the aspect of its adequacy. However, it is not easy to apply in the practical business affairs since there exist some difficulties on the economic analysis and the interpretation of the result because of the difficulty of the estimation of the discount rate. This study aims to suggest a method of the financial feasibility study based on the economic analysis. The results of this study are as follows. First, this study can increase the reliance and adequacy of the economic analysis result by suggesting a method of estimating the discount rate by means of the proxy ${\beta}$ method in the practical way. Second, this study can provide the overall frame of the financial feasibility study based on the economic analysis method (namely, Net Present Value Method internal rate of return, profit index method and payback period method)which use discount rate and cash flow. Third, this study can suggest an practical analysis skill required in each step of the financial feasibility study.

  • This study was carried out for preliminary feasibility review to consult forest farmer, to make policy and to search improvement for Ligularia fischeri forest farm. The survey for eight Ligularia fischeri forest farmer in Inje-gun was conducted. And the case study was conducted with computing labor input, gross margin, net margin in each planting stages, which is contented each cultivating stage from creating to harvesting. B/C ratio, Net Present Value and Internal Rate of Return were used for profitability analysis. The results applied 3% of discount rate showed IRR 48.6%, B/C ratio 1.5 and NPV 41 million KRW, which means high profitability. Forest farming is early step in Korean forestry so that standard methods of cultivation for that haven't established yet, and differences among farmers in productivity are being. Establishing organized methods of cultivation in each stages and being political supports are essential for income generation to forest households, supply of safe food and rest place for urbanity.

  • An feasibility analysis is performed for the tidal current power generation with the examination of the sea water speed distribution at Pungdo. In this analysis, the water speed distribution which is the key issue was obtained from the actual speed distribution data and results in "the annual current tidal power". Due to the lack of cost information, we applied EPRI data from the internet site instead of the actual information. The result could be used as a base data for the construction of current tidal power plant in the near future. And it is expected to provides good data for the Energy policy.

  • The shipbuilding and offshore plant industry of Korea is important and leads Korea's economic growth, designated as the 1st to 4th export items in Korea in terms of export contribution over the period from 2011 to 2015. This study proposes ways to improve the national competitiveness of Korean shipyards in the global offshore drilling market by reviewing a business model for providing an integrated offshore drilling commissioning service in Korea. This commissioning service model, which was attempted in 2014, was reviewed, and a new proposed business model for overcoming the limitations of the previous model and activating further business was evaluated. As a result of an economic evaluation, it was found that a 150-meter water depth model is economically more effective. As the number of integrated commissions increased from 2 to 5 times per year, NPV, IRR and B/C ratios increased and the fee per use decreased. Therefore, for offshore drilling facilities constructed and delivered in Korea, it will be necessary to encourage integrated offshore commissioning.
