고객가치에 기반을 두지 않은 소프트웨어는 블루오션을 창출할 수 없고, 기존 시장에서 우위를 점유할 수 없으므로 최근에는 고객가치와 품질 향상에 초점을 맞춰 소프트웨어 개발이 이루어지고 있다. 또한 시장에서 우위를 차지하기 위한 중요한 요소 중 하나가 비용인데, COTS 기반의 개발방법은 시장출하 시간의 단축과 비용절감의 효과가 있어 관심이 증가하는 추세이다. 본 논문에서는 고객가치를 창출하고 소프트웨어 품질을 향상시키기 위해 고객가치와 COTS의 품질속성을 고려하여 COTS를 선택하는 요구공학방법론을 제시하였다.

This paper measures power quality of bus in case electric charges about customer are imposed by each bus, supposed that can calculate this cost. When reflected this in system planning, expected cost proposed following method through sample system. To calculate nodal cost operating condition of power equipment calculates nodal cost[$/MVAH] supposing by situation that is optimized by OPF(optimal power flow) in system. The damage cost that is shed by fault that happen during year of loads in system that is linked on each bus was produced. As a result, proposed method was very effective in case of calculating bus total cost including power quality cost.

Warranty cost of automobile parts varies depending on the parts failure rate in a warranty region of individual markets. Parts failure rate is significantly affected by usage-rate given that other stressors of individual markets are similar. Accordingly, warranty cost can be predicted by failure modeling which reflects usage-rate and using a stochastic process. In this paper, one-dimensional approach is used by applying accelerated failure time model on the assumption that the usage-rate is linear. Such model can explain changes in parts failure rate depending on the changes in usage-rate since it can be expressed as a function of usage-rate. Therefore, acquisition of usage-rate in a new market will automatically lead to estimate of failure rate even without warranty data and warranty cost of parts can be predicted through a renewal process in replacement cases. A case study using warranty data of two real markets is presented in the application part of this paper.

본 연구의 목적은 현재 급속히 확산되고 있는 온라인 뱅킹의 수용에 영향을 미치는 요인을 분석하기 위한 것으로, 기존 연구를 바탕으로 서비스 품질과 비용이라는 온라인 뱅킹 서비스 관점, 이용자의 태도의 관점(유용성, 용이성, 사용자 특성), 그리고 사회적 영향의 관점을 변인으로 추출하였다. 한편 성숙기에 접어든 인터넷 뱅킹 서비스와 도입기에 있는 모바일 뱅킹 서비스를 비교하기 위해 온라인 뱅킹 서비스 유형이라는 조절변수를 사용하였다. 연구 결과에 따르면, 유용성과 용이성, 개인사용자 특성, 사회적 영향, 서비스 품질, 비용의 모든 요인 이 온라인 뱅킹 서비스의 수용에 유의한 영향을 미치는 것으로 나타났다. 그러나 사회적 영향과 비용 은 인터넷 뱅킹과 모바일 뱅킹 서비스간에 영향 정도가 다른 것으로 나타났다.

Qualify Function Deployment(QFD) is a technique which was born in Japan as a strategy for assuring that quality is built into new products. QFD was first used in 1972 by Kobe Shipyard of Mitsubish Heavy Industrials Ltd. and was then referred to as the quality tables. After QFD is proposed, it has been applied by both many large and small companies around the world. Many studies related QFD are performed till now but study related "cost-based QFD(QFCD)" hasn't been performed actively. If cost-based QFD is not performed. the produced results will be included possibility that is not significant as well as realistic. Therefore, the purpose of this study is to improve effectiveness and efficiency for product development's result through QFD by introducing QFCD's concept and execution procedure.

Quality system of construction industry in Korea was a means to prevent unqualified construction work. But lately, it has became an essential requirement. So, lots of construction companies acquire ISO quality management system which provides fundamental management criteria. Now, most of the Korean construction companies have got IS0 quality management system. So, getting ISO quality management system doesn't mean advantage in public competition of construction bidding and that causes increase in the maintenance cost. That's why some construction companies abandon the 150 certificate. Therefore, the authors need to check the effect of ISO quality management system. For this, the authors provide the performance measurement index of ISO quality management system.

A service network design model for LTL freight transportation is formulated as a mixed integer Programming Problem with two heuristic solution a1gorithms. The Proposed model derives the transportation Path for each origination-destination pair, taking into account transportation cost over the links and handling costs over the nodes. The first algorithm searches for a local minimum solution from a given initial solution by improving the quality of solution repeatedly while the second a1gorithm searches for a better solution using Simulated Annealing Method. For both solution algorithms, the initial solution is derived by a modified reverse Diikstras shortest Path a1gorithm. An illustrative example, Presented in the last part of the Paper, shows that the proposed algorithms find solutions which reduce the cost by 12% and 15% respectively, compared to the initial solution.

This study attempts feasibility analysis of cataloging outsourcing. The economic analysis model based on information economics categorizes the benefit into direct benefit and value linking. We measure direct benefit by cost savings and cost avoidance, value linking by the degree of improvement in cataloging quality The results show that there is no feasibility overall, because librarians spent more time to control the quality due to vendor's lack of professionalism, resulting little effect on cost savings. When cataloging outsourcing is forcibly used under the economically infeasible condition, it is impossible to achieve the basic purpose of operating cost savings and improvement of service function.
