Data Envelopment Analysis (DEA) is a methodology of computing the relative efficiency of each decision making unit (DMU) by comparing it with other DMUs having similar input and output structure. In this paper, we compare the efficiency of Korean rail transit corporations using DEA. To do this, we design a DEA-AR/AHP model, and evaluate efficiency by comparing the subway operating agencies of six big cities. The analysis reveals that Seoul Metro and Seoul city railroad construction turn out to be the most efficient groups. The result of this research can provide helpful information for effective management in a domestic subway operating agency.

This study focuses on the detailed explanation of the strategic allocation algorithm which can be used as an ATP(Available To Promise) from the perspective of customers, and as a sales plan for sales organizations. A strategic allocation algorithm includes three methods depending on FIXED RATIO, RANK and DEMAND BASIS. In addition, further topics would be discussed regarding the method of system implementation utilizing strategic allocation algorithms and information flow with an aim to integrate such a sales plan into the e-Biz. This study aims to provide a new solution in order to secure emerging competitive factors in today's enterprise world; that is, an achievement of faster business processes. It is suggested that this new solution be implemented in order to achieve an efficient business environment by systemizing the decision making process which in the past was manually conducted.

The objectives of this study are to analyze and compare importance degrees of rural amenity resources for rural development project using AHP and ANP (Analytic Network Process) which can be applied a complex decision making problem. For this study, I chose the 5 rural development project types and the 10 rural amenity resources as major criteria and formed the ANP network from relations with criteria. The importance degree matrix were derived by the results of AHP and several ANP analysis. As the results of this study, the importance degrees of 10 rural amenity resources are determined and the indigenous product resource is identified as the most important resource in general rural development project.

In this study, we consider various methods to estimate the weights of a pairwise comparison matrix in the Analytic Hierarchy Process widely applied in various decision-making fields. This paper uses a data dependent simulation to evaluate the statistical accuracy, minimum violation and minimum norm of the obtaining weight methods from a reciprocal symmetric matrix. No method dominates others in all criteria. Least squares methods perform best in point of mean squared errors; however, the eigenvectors method has an advantage in the minimum norm.

최근 재사용성에 근간을 둔 컴포넌트 기반 소프트웨어(Component-Based Software : CBS) 기술의 실현에 따라 이와 관련된 유지보수 의사결정의 내용도 변화하여 새로운 연구 과제로 등장하고 있다. 이에 본 연구는 컴포넌트 기반 소프트웨어 유지보수와 관련된 의사결정의 이론적 근거를 탐색하고 컴포넌트 평가 및 선택을 위한 모형 개발을 목적으로 한다. 모형 설계에는 평가 기준의 체계를 수립하고 적절한 평가 기법의 선택 및 적용이 포함된다. 평가 기준 구성을 위하여 CBS 유지보수의 특성을 고려한 다차원적 접근법에 의한 계층적 체계화를 시도하였으며, 일부 상호 종속적 관계를 나타내는 요소들에 대하여는 네트워크 관계를 나타내는 모듈로 포함시켰다. 체계화된 평가 기준에 따른 의사결정 대안의 평가 기법으로 주관적 판단의 계량화에 적절하다고 판단되는 계층분석과정(Analytic Hierarchy Process) 기법 및 네트워크분석과정(Analytic Network Process) 기법을 선정하고 적절한 예를 들어 모형 적용의 이해를 돕고자 하였다.

In modern dynamic management environment, there is growing recognition that? information & knowledge management systems are essential for CEO's efficient/effective decision making. As a key component to cope with this current, we suggest the management performance analysis syystem based on Knowledge Discovery in Database (KDD). The system measures management performance that is considered with both VA(Value- Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view. The relation ship between management performance and some 80 financial ratios is analyzed, and then important financial ratios are drawn out. In analyzing the relationship, we applied KDD process which includes such as multidimensional cube, OLAP(On-Line Analytic Process), data mining and AHP(Analytic Hierarchy Process). To demonstrate the performance of the system, we conducted a case study using financial data over the 16-years from 1981 to 1996 of Korean automobile industry which is taken from database of KISF AS(Korea Investors Services Financial Analysis System).

Purpose: We explored emergency nurses' experiences of coping with moral distress. Methods: A qualitative research design was used. We conducted in-depth interviews with 11 nurses working at a regional emergency medical center in South Korea. Data were analyzed using conventional content analysis. Results: The main theme of nurses' coping with moral distress was "a passive emotion-based response." We also extracted three categories of coping strategies: "uncritical adaptation to anguished situation," "self-justification for not acting," and "flight from ethical decision making." Conclusion: Nurses coped with moral distress in a passive and emotional way, possibly because of perceived incompetence and compliance to an organizational hierarchy. The findings imply that effective approaches to addressing moral distress in emergency nurses are needed at the individual and organizational levels.

The introduction of new equipments to strengthen the competitiveness of enterprises is one of pretty important factors. Enterprises introducing new equipments strengthen competitiveness through productivity increasing, high quality maintenance, inventory reduction, improved design and production interface, simple scheduling process, low scrap rate, rework reduction, etc. Managers will work out the best equipment-replacing strategy through the appropriate combination of potential cost attributes and qualitative attributes difficult to quantify in accordance with the business purpose. This study is to present a method to select an equipment-replacing alternative through the decision-making model of Analytic Hierarchy Process in consideration of the differences of cost flow of the alternatives, taking into consideration tangible attributes and strategic intangible attributes.

This study focuses on the policy priorities for training agro-healing experts. Training agro-healing experts is an important task that should boost local community in rural areas. In order to make an efficient decision making, the study analyses priority of relevant policies using the AHP(Analytic Hierarchy Process) method. According to the results, R&D comes out first. Human Resource Development(HRD), financial support, and the construction of legal system comes after R&D. In R&D, qualifications and guidelines for participants comes out the most significant issue. In the aspect of HRD, it is very important to develop and utilize regional personnel such as unemployed youth and retirees from related fields. As for financial support, funding for educational facilities (i.e. classrooms and farmland for practice) is needed. In case of legal system, it is desirable to introduce the recruiting experts system and qualification system certified by government.
