최근 국가상위계획에 반영된 교통SOC 사업이 예비타당성조사단계에서 중단 지연됨에 따라 투자평가방법 및 제도의 실효성에 대한 관심이 높아지고 있다. 특히, 현재 시행되고 있는 투자평가제도간 중복 및 일관성 부족 등으로 인해 불필요한 예산 및 시간 그리고 인력낭비가 발생된다는 논란이 제기되고 있다. 일례로 국가재정의 효율적 운영을 목적으로 예비타당성조사가 도입되었으나 타당성 평가와 분석방법 및 평가내용이 유사하며, 효율적 교통체계구축을 촉진하기 위해 도입된 타당성 평가 또한 현재 타당성 조사가 그 기능을 대신하여 타당성 평가가 유명무실해 지는 등 주먹구구식 투자평가제도 도입으로 인해 효율적인 교통SOC투자가 이루어지지 못하고 있는 실정이다. 이에 본 연구에서는 현재 수행되는 투자평가제도의 도입취지 및 운용현황을 살펴봄으로써 각 제도에 대한 이해도를 제고하고, 이를 토대로 현 투자평가체계의 효율화를 위해 각 투자평가제도간 연계성 강화방안을 제시하였다. 본 연구를 통해 현재 수행되는 투자평가제도를 체계적으로 정리할 수 있는 토대가 마련되어, 교통SOC투자제도의 합리성, 일관성 및 효율성 향상에 기여할 것으로 사료된다.

Since 'The Act on Private Investment of The Infrastructure' was established in 1994, private investment as well as government's investment in transport infrastructure has been active. However investment in transport infrastructure has more risks than others' due to uncertainty both in traffic volume and in construction cost. In the current appraisal procedure of deciding transportation infrastructure investment, instead of risk management, the sensitivity analysis considering only the changes of benefit, cost and social discount rate which are main factor affecting economic feasibility is carried out. Therefore the uncertainty of various factors affecting demand, cost and benefit are not considered in feasibility study. In this study the problems in current investment appraisal system were reviewed. Using Delphi technique the major factors which have high uncertainty in feasibility study were surveyed and then improvement plan was suggested in the respective of classic 4 step demand forecasting method. The range estimation technique was also mentioned to deal with the uncertainty of the future.

Governments around the world invest in research and development (R&D) for different purposes : national economy, defence, environment, health, etc. as a means of national survival beyond the means of national competitiveness. These are usually programs with high social impact but low short-term economic impact or large scientific programs that are too expensive and risky for private sector investment alone. The Republic of Korea has also shown a very successful model of economic progress and social development through government R&D programs. However, there have been many corruption scandals behind it while selecting awardees for government R&D programs in Korea. So, the Republic of Korea focused on reforming appraisal system for government R&D and began preparation for "Clean Appraisal System" last year. In this study, first we analyzed the related appraisal tasks through the review of laws and administrative rules and typed appraisal tasks according to the flow of the actors and time. Thus securing the information infrastructure and finally we drew the conceptual model of the system according to an open appraisal tasks by introducing an element of the OECD on open government typed appraisal tasks.

Recently, it has become important to establish a technology appraisal system because of increasing a service of technology credit guarantee. Also, there have been many efforts to evaluate a technology in the advanced countries. The technology/credit appraisal model which can measure firms' performance was suggested by Small and Medium Business Administration. In this paper, we analyze a structural validity of the model by confirmatory factor analysis and estimate the model which can distinguish whether an investment is possible or not by discriminant analysis.

In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.

Quality is a critical competitive factor in today's environment because of the impact of quality on costs and delivery. Many companies regard quality as a key concept of company strategy in order to achieve the competitive edge. Measuring and reporting quality cost is the first step in quality management program. The supposition of quality cost model is that investment in prevention activities will bring rewards from reduced failure costs, and that further investment in prevention activities will show profits from reduced appraisal costs. In this study, the degree of quality cost deviation is conceptualized. This means a deviation between the ideal and present ranking in the amounts of quality cost categories. This study analysed that the effect of its deviation on quality management activity and performance variables. However, there are no difference in these variables. The major reason is that most of companies are endeavoring for quality management but operating quality cost system unsystematically. The review against a prevention and appraisal activity is necessary.

Each method for economic evaluation has its own characteristics. Therefore adoption of each of them in evaluation production investment project results in many problems. Hence combination & modification of them are required to perform more accurate evaluation about investment project. This paper discuss evaluation method of investment projects expansion and replacement investment on each line or individual in the production. Generally investment evaluation method has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Taguchi Techniques is presented, which may be effective to the facilities appraisal or improvement. We propose a decision model to incorporates the values assigned by a group of experts on different factors in production. Using this model, SN ratio of taguchi method for each of subjective factors as well as values of weights are used in this comprehensive method for reducing production rate in production management.

As technique that can contribute in quality improvement in design process to overcome shortcoming of traditional quality control, call design or development department quality control activity that is achieved to reduce gun damage shuddering at circle minimizing change or side effect of product performance as off-line quality control. This paper discuss optimal process design of investment projects expansion and replacement investment on each line or individual in the production. Generally optimal plant design has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Robust design is presented, which may be effective to the processes appraisal or improvement. We propose that should make a optimal plant design model for reducing field failure rate to assign by real data on different factors in plant system. Using this model, robust design of taguchi method used in this comprehensive method for reducing field failure rate in plant system.

본 연구는 투자용 기술평가등급모형 개발에 대한 사례연구이다. 투자용 기술평가등급모형은 기술금융의 지원대상을 융자에서 투자로 확대하기 위하여 금융위원회와 산업통상자원부가 협업으로 추진한 프로젝트이다. 실제개발은 기술보증기금과 산업기술진흥원이 진행한 것으로 기술형 투자펀드를 운영하기 위하여 사전에 TCB가 운영할 표준모형을 개발한 것이다. 투자용 기술평가모형은 고성장기업을 예측하는 것을 목표로 개발하였다. 모형은 통계모형과 전문가모형으로 구성하고 이를 종합하여 등급을 산출하는 구조로 구성하였다. 여기서 통계모형은 예측에 유의한 변수를 파악하여 이를 로짓회귀분석을 활용하여 모형화하였다. 전문가모형은 전문가들의 의견을 수렴하여 각 평가항목의 가중치를 파악하여 모형을 설정하였다. 전문가는 벤처기업 투자를 하는 벤처캐피탈리스트와 모형을 운영할 TCB의 심사역의 의견을 종합하였다. 모형의 등급체계는 10등급으로 구성하여 제시하였다. 그 모형의 등급별 분포는 기보의 KTRS 등급별 분포와 일치하도록 하였다. 흥미로운 것은 기술성과 시장성 을 중시하고 있다는 것이다. 여신을 위한 기술평가등급모형에서는 경영자역량이나 사업성을 중시하고 있는 것과는 상당한 차이가 있는 것이다.

트램은 타 경전철과는 달리 도로에서 자동차와 혼용운행이 가능하다는 큰 특징을 가지고 있으며, 베를린, 뮌헨, 파리, 리스본 등 국외에서는 노선 버스와 일부 노선 및 정거장을 공유하는 사례도 존재한다. 현재 투자평가제도 상에서는 교통수요예측 및 편익산정 시 트램을 경전철 중 하나의 수단으로 구분하고, 도시철도의 분석방법론을 준용하고 있으나, 노선버스 특성과 유사한 트램사업 중 비수도권 사업의 경우 KTDB 배포자료에 노선버스의 O/D 및 Transit Line을 제공하지 않아 사업노선 주변 노선버스에서의 수단전환 등의 통행행태를 반영할 수 없는 구조적인 문제점이 존재한다. 본 연구는 현재 비수도권 사업에서 고려되지 않고 있는 노선버스가 트램사업에 미치는 영향을 검토하기 위하여, 현황 검토 및 문제점을 도출한 후, 노선버스 반영 여부에 따른 트램사업의 효과를 분석하여, 수요예측 및 편익산정 개선방안을 제시하였다. 본 연구를 통해 향후 투자평가체계 개선을 통한 트램사업 도입여건에 변화를 줄 수 있을 것으로 기대한다.
