This paper is concerned with development of a performance evaluation model for material handling system in cellular manufacturing system based on multi-attributes analysis method. We used the AHP(analytic hierarchy process) and fuzzy set ranking methodologies to overcome the special decision problems; those of multi -objective, multi-criterion, and multi-attributes. We proposed a 3-step approaches and we developed a systemic and practical computer program to solve the problems in the proposed methods. Computational experiments are then performed to cellular manufacturing system and show the effectiveness of the proposed model.

This study analyzed the priority of decision-making attributes considered as the customers select the family restaurant with Analytic Hierarchy Process, which is the method for quantitative analysis. The result of analysis revealed that the food factor in the first stage of evaluation attributes was the most important and in the second stage, an atmosphere factor of place, an affiliated card factor of promotion, a taste factor of food and a kind attitude factor of employee were important respectively.

본 연구는 여러 가지 데이터마이닝 기법으로부터 도출된 지식이 어떻게 인간의 판단에 영향을 미치는 가를 지식구조별, 자료특성별, 전문가지식의 일관성별로 실증적 연구를 하여 궁극적으로 전문가 의사결정에 도움이 되는 데이터마이닝 기법의 활용방안을 제시하고자 한다. 분석결과 전문가들의 판단은 데이터마이닝의 지식표현형태에 의한 영향을 많이 받고 있는 것으로 나타났으며, 특히 IF-THEN의 형태로 표현되는 명제형 지식구조에 가장 많은 신뢰를 갖는 것으로 나타났다. 특히 자료의 특성, 또는 전문가의 판단 일관성과 데이터마이닝 기법 사이에 상호작용효과가 있어 향후 데이터마이닝 기법을 활용하여 전문가의 의사결정을 돕고자 할 때는 이러한 차이점을 고려해야 하는 것으로 밝혀졌다.

The purpose of this paper, the 2nd stage of this study. is to test the applicability of the potential centrality evaluation model (PCEM) to a case study area. To verify the practical applicabilities of the PCEM, an administrative area of Ucheon-myeon, Hoengseong-gun, Gangwon-do was selected as a study area. Full data on the human environments of total 72 villages within the study area were surveyed. Data on the natural environments were collected through GIS analysis from digital maps developed far this study. The highest PCI (Potential Centrality Index) score was shown at Uhang village of which one being 841 (total score being 1,000), the real single center village of the study area. The evaluation results on potential centeralities of all the villages in the study area would provide decision-makers with more precised information for selection of center villages for development project.

The military vehicles are necessary to perform various war battle missions but in reality they are not as convenient as the civil vehicles. Thus, it is problematic regarding the satisfaction about convenience, operation, and performances of military vehicles. Since most of military vehicles used in Korea were made by bench-marking the models of United States developed in the latter half of 1970's. It is question whether the current military vehicles can provide the functions and expected performance fully or not if we do not study what the user friendly military vehicles are. This article report soldiers' user satisfaction survey on military vehicles and provide arguments on the priority decision based on users' requirements. Future direction for the development of military vehicles is discussed.

It is well known and widely accepted that the conceptual design is the most influential step in the design process of a product or a system and that about 75% of the life cycle cost is committed as the results of this stage. The purpose of this paper is to present and demonstrate the step of ICDM(Integrated, Customer Driven, Conceptual Design Method) for the development of a ground launcher system, TEL(Transporter, Erector and Launcher). The results of the study show the effectiveness of the method during the conceptual design phase of new complex systems or high-tech products.

Selection of optimal railway line is taken into consideration include of the purpose of railway, geographical features and facility of management. This study performed opinions of specialists, checking of industrial environment, analysis of bid guideline to select the optimal line and executed AHP method to make quality model and choose weight factors. Therefore, this study executed about six categories which are the efficiency of transportation, facility of planning and construction, economical efficiency, coincidency of planning, the civil appeal and environmental standards, connection with system, and indicated the differences of other method by analyze into specific factors of each categories.

This research proposes a new risk analysis method in order to guarantee successful performance of construction projects. The proposed risk analysis methods consists of four phases. First step, AHP model can help contractors decide whether or not they bid for a project by analysing risks involved in the project. Second step, the influence diagraming, decision tree and Monte Carlo simulation are used as tools to analyze and evaluate project risks quantitatively. Third step, Monte Carlo simulation is used to assess risk for groups of activities with probabilistic branching and calendars. Finally, Fuzzy theory suggests a risk management method for construction projects, which is using subjective knowledge of an expert and linguistic value, to analyze and quantify risk. The result of study is expected to improve the accuracy of risk analysis because three factors, such as probability, impact and exposure, for estimating membership function are introduced to quantify each risk factor. Consequently, it will help contractors identify risk elements in their projects and quantify the impact of risk on project time and cost.

This Study is to suggest marine tourism development strategy of Yeosu city using a A'WOT analysis technique. Main findings of this study are summarized as following. First, SO(strength-opportunity) strategy is considered as the most important strategy and followed by ST(strength-threat), WO(weakness-opportunity) and WT(weakness-threat) strategy. Second, it can be concluded that marine tourism facility and contents development is considered as the most important factor and followed by marine sport-related marine training program development and so on. For further research, more concrete and empirical study is to be performed by each strategy in the future.
