The objective procedure and criterion needs to efficiently perform the safety assessment and improve reliability for results of the cost analysis. There are many studies about cost analysis of safety assessment, but the these studies have problems such as non-quantification of criterions and methods. The purpose of this study to suggest the procedure and criterion for successful cost analysis and quantify cost factors. First, in the cost analysis of the housing reconstruction that is presented this study, determinate the life-cycle and the discount rate, then estimate reconstruction cost and remodeling cost. Finally, compare the annual equivalent LCC of two costs for decision malting to reconstruction or remodeling.

In order to estimate the life cycle expense of the weapon system acquisition from the first demand planning phase until the last disuse phase, we apply the reliable expense analysis method to the current situation in Korea by using the sensitivity analysis. We estimate the total cost of the weapon system acquisition by focusing on the most important variables such as exchange rate, and hence by strengthening the function of the existing expense analysis method, which is used to be simply recognized as a tool of cost reduction. Therefore, this study could make a contribution to the literature in this area, in terms of deriving the most cost-efficient method of acquisition by comparing the various estimated costs that result from the different alternatives of the weapon system acquisition.

Recently, the acquisition environment of the Korean defense weapon system is emphasizing more the importance of cost analysis in terms of efficient execution for defense acquisition budget. While cost analysis, however, is emphasized in law and process, its infrastructures are still insufficient We have been using computerized cost models to obtain an estimate at early phase of project. But those models have been developed by foreign companies, and so they have many limitations when using in Korean defense environment. For this reason, it began to sympathize that we need the development of the Korean version cost estimation model suitable for our defense industry environment, and now many studies are proceeding. In this study, we suggest Cost Estimating Relationships(CERs) developing methodologies which is key logics of Korean version cost estimation model. Especially, we proposed a new CER's development process depending upon data characteristics such as, multicolinearity, outlier, small samples and heteroscedasticity. Also, we presented a case study for artillery weapon system using these methods we developed. We find that these CERs could be verified through theoretical methods.

The GIS(Geographic Information System) projects require big initial investment and cost of maintenance. Decision makers would not launch GIS projects unless they are convinced of the benefits of the projects. Therefore the purpose of this paper is to develop an appropriate model for GIS project evaluation. We proposed a GIS project evaluation model and summarize the steps involved in Cost-Benefit Analysis(CBA). The costs of a GIS implementation include hardware and software cost, costs of database development, training expenses, annual maintenance expenses, and other annual expenses. The benefit by using GIS has been assessed into Type I(direct benefits), Type II(indirect benefits), Type III(benefits that result from the sale of information services), Type IV(intangible benefits).

교통사고는 인적피해, 물적피해, 사회적피해와 거시적으로는 심리적 피해까지 일으키며 많은 비용을 발생시킨다. 이처럼 교통사고로 인해 발생하는 다양한 피해요소를 비용으로 환산하여 추정하는 것은 교통안전사업의 절감편익을 산정하거나 기타 교통관련사업의 효과를 적용하기 위하여 활용할 수 있다. 하지만 현재까지 이루어진 사고비용 산출에 대한 연구론은 1당사자와 2당사자 구분없이 사고 전체를 아우르는 피해비용을 산출하는 방식의 접근 방법과, 사상자 1인 기준으로 발생되는 피해비용을 산출하는 방식의 접근 방법으로 나뉘며, 두 접근방법 모두 비용분석의 대상을 단일 객체로 간주하고 분석하는 한계를 지니고 있다. 이에 본 연구에서는 특정한 상호작용효과가 있을 것으로 예상되는 고연령 구간을 확인한 뒤 고연령 구간과 전체 연령 구간 사이에서 발생된 사고를 비교분석하여 1당사자와 2당사자가 모두 고연령 구간일 때 추가로 발생되는 사고비용을 산출 및 검정함으로서 고령자 사고감소효과 및 절감편익에 활용될 수 있는 상호작용 효과에 따른 추가 절감편익을 산출하였다.

The purpose of this paper is to analyze cost-effectiveness of a train simulator. The cost-effectiveness of training program is assessed by multiplying transfer effectiveness ratio (TER) by training cost ratio (TCR). If their product is less than one, the program is not cost effective. Even if a program is not cost effective, however, safety considerations may be important to consider. Findings indicated that each type of train simulators might be used with each type of training programs appropriately for improving cost-effectiveness of a train simulator.

현재의 제조의 원가 절감 차원에서 물류비용에 대한 많은 관심을 가지고 있다. 하지만, 그에 대한 물류비용에 대한 정확한 추정에 대해서는 계산이 복잡할뿐더러 제품의 운송거리나 제품의 무게 및 수량등 선형적인 값으로 나타내는 방법을 주로 사용하여 비용만을 예측할 뿐이다. 물류비용에 대한 세부적인 산출에 대한 연구보다는 전체적인 비용을 산출하는데 많은 연구가 진행되어 왔었다. 그리고 어느 특정 제품에 대한 물류비용에 대한 추정과 예측하는 연구에 대해서는 부족한 형편이다. 일반 기업에서는 하드웨어에서의 원가비용절감에 한계를 느끼고 물류에서의 비용을 절감을 위해 많은 연구가 이루어진 반면 군에서는 물류비용 추정에 관해서는 연구가 많이 이루어지지 않고 있다. 본 논문에서는 군에서의 물류의 흐름에 맞는 물류 네트워크를 제안하고 물류 네트워크상에서의 비용 모델을 제시하여 군에서의 물류비용을 추정하였다. 그리고 이에 대한 분석과 함께 물류네트 워크상에서의 물류비용 절감을 위한 방법을 제시하였다.

In this study, DEA (Data Envelopment Analysis) was carried out on the four bridges, which have the same extension (L=1,615m), in order to select the most superior, economical method of construction using the LCC concept of each bridge structure in the case of the Ulsan-Pohang double track railway which is scheduled to be constructed. DEA models were analyzed with the CCR model, which was designed for the evaluation of relative efficiency of each model. The initial construction costs, maintenance costs, indirect costs (user costs + indirect loss of social costs), and life cycle costs were used as input variables, and average duration was applied as the output variable. LCC was applied to calculate the input variables, and to get the costs of LCC, 100 years of period and 4.83% of real discount rate were applied, and the costs are classified into initial construction, maintenance, user, and indirect loss of social cost. The analysis results showed that the Method 2 and 3 were evaluated as the most efficient, and the other alternatives were evaluated as the following order; Method 1, the default, and Method 4.

비용편익분석은 어떤 사업으로 인하여 자연배분의 변화가 생길 때 그에 따른 경제적 편익을 측정하게 되며 사업을 시행하여 생기는 편익과 비용을 비교하여 경제성을 평가하고 대안 중에서 우선순위를 결정할 때 유용하다. 따라서, 본 논문은 자본에 관한 투자기준을 마련하기 위해서 분석용 모델인 "비용편익분석"을 활용 하여 제조기업의 어떤 사업계획에 의하여 생겨나는 자본요소가 어떻게 투자되어야 생산비용을 최소화 할 수 있는지를 자본투자에서 가장 핵심적인 생산설비투자와 기술개발투자에 대한 비용편익분석을 통하여 그 방법론을 제시함으로써, 자본투자에 있어서 "비용효과분석"의 활용성을 확인하고자 한다.
