  • In this age of "Information", many people consider it a deterrent to information flow to provide a hierarchy with private rooms in a modern office layout. There are others, however, who insist that visual and acoustical privacy are more important than any other design factor in achieving higher productivity. The debate may never end, but the partitioned open plan, which is a new form of the vast open plan, has merits of each concept - open and closed layout. Consequently, office design has dramatically shifted to partitioned open planning, with shorter, temporary walls or partitions, originally intended for increasing privacy and diminishing hierarchy, yet still keeping flexibility in spatial organization. The introduction of low-level partitioned spaces in an office layout, however, produces a complicated lighting design problem. Obviously, accurately predicted daylighting performance data are needed not only for daylighting design but for artificial lighting system design. Scale models of 12 sets of unit partitioned spaces are constructed and extensive scale model measurements of both daylight and reflected sunlight have been performed within an artificial sky simulator. The prototype-building interior is modeled with different partition configurations, each of which is modeled using the different envelope geometry and exterior configurations, and then the variations in interior light levels are estimated. The result indicates that partitioned spaces employed in an open plan of modern offices still offer a large potential for daylighting and energy saving as well. Much of the savings may derive from the cumulative effect of reflected sunlight. Optimal design for building envelope geometry and exterior configuration promises additional savings.

  • Supplier selection is one of the most important activities of a company. This importance is increased even more by new strategies in a supply chain, because of the key role suppliers perform in terms of quality, costs and services which affect the outcome in the buyer's company. In addition, green production has become an important issue for almost every manufacturer and will determine the sustainability of a manufacturer. Therefore a performance evaluation system for supplier and green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. Supplier and green supplier selection is a multiple criteria decision making problem in which the objectives are not equally important. In practice, vagueness and imprecision of the goals, constraints and parameters in these problems make the decision making complicated. The objective of this study is to construct a decision-making process using fuzzy analytic hierarchy process (FAHP) and balanced scorecard (BSC) for evaluating supplier and green suppliers in the manufacturing industry. The BSC concept is applied to define the hierarchy with four major perspectives and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is applied to facilitate the solving process. With the proposed approach, manufacturers can have a better understanding of the capabilities that supplier and green supplier must possess and can evaluate and select the most suitable supplier for cooperation.

  • In this study, the axiomatic design(AD) method is applied to construct the hierarchical structure of evaluation criteria and the AHP method is used to calculate the weights of criteria in order to develop the proposal evaluation index for the overseas weapon system purchasing projects. The common evaluation items as main categories are selected through the review of evaluation criteria from the previous works and projects, relevant regulations and defense policy, and the design matrix using fuzzy concept is established and evaluated by the expert group in each design phase to determine the independency, that is the satisfaction of decoupled or uncoupled design, for each criteria in the same hierarchy when they are derived from the main categories. The establishment of decoupled or uncoupled design matrix provides mutually exclusiveness of how small number of DPs can be accounted for FRs within the same hierarchy. The proposal evaluation index developed in this study will be used as a general proposal evaluation index for the overseas weapon system purchasing projects which there are no systematically established evaluation tools.

  • Due to the increasing occurrence of maritime accidents and high-level requirements and modernization of naval wars, the concept of ship environment adaptability becomes more and more important. Therefore, it is of great importance to carry out an evaluation system for ship environment adaptability, which contributes to both ship design and classification. This paper develops a comprehensive evaluation system for ship environment adaptability based on fuzzy mathematics theory. An evaluation index system for ship environment adaptability is elaborately summarized first. Then the analytic hierarchy process (AHP) and entropy weighting methods are applied to aggregate the evaluations of criteria weights for each criterion and the corresponding subcriteria. Next, the multilevel fuzzy comprehensive evaluation method is applied to assess the ship integrative environment adaptability. Finally, in order to verify the proposed approach, an illustrative example for optimization and evaluation of five ship alternatives is adopted. Moreover, the influence of criteria weights, membership functions and fuzzy operators on the results is also analyzed.

  • As environmental protection is becoming more and more important, green production has become a key issue for almost every manufacturer and will determine a manufacturer can be sustainable in the long term. Therefore a performance evaluation system for green suppliers is necessary to determine the suitability of suppliers to cooperate with the company. While the works on the evaluation and/or selection of suppliers are abundant, those that concern environmental issues are rather limited. The objective of this study is to construct a combined model based on fuzzy analytic hierarchy process (FAHP) and balanced scorecard (ESC) for evaluating green suppliers in the manufacturing industry. The ESC concept is applied to define the hierarchy with four major perspectives (i.e. financial, customer, internal business process, and learning and growth), and performance indicators are selected for each perspective. FAHP is then proposed in order to tolerate vagueness and ambiguity of information. Finally, FAHP is finally constructed to facilitate the solving process. With the proposed model, manufacturers can have a better understanding of the capabilities that a green supplier must possess and can evaluate and select the most suitable green supplier for cooperation.

  • 유비쿼터스 서비스가 여러 분야에서 실용화 단계에 와 있다. 특히 u-쇼핑 분야에서는 사용자의 상황에 맞게 상품 혹은 상점을 유연하게 추천해 주는 개인화된 추천이 필요하다. 그러나 현재의 협력적 질의나 상황인식적 검색은 각각 동적 상황과 모호한 검색을 처리하지 못한다는 한계가 있다. 따라서 본 연구의 목적은 이 두 가지 중요한 문제를 해결하기 위하여 개인화된 상황인식적이고 협동적인 검색방법을 상황적MKAH를 유도방법으로 제안하는 것이다. 본 연구의 가능성을 보이기 위해 CACO라고 하는 프로토타입 시스템을 구현하였으며 국내의 한 대규모 쇼핑몰 도메인에 맞게 적용하였다.

  • Purposes: Rapid aging and increase of high chronic diseases of the elderly are increasing the needs for expanding elderly care beyond the concept of treatment in medical institutions. This study is to discuss the core values, functions, and roles of municipal hospitals and suggest a suitable community care model. Methodology: The survey was collected twice derived from the domestic expert groups. This study analyzed experts' responses using Delphi method and Analytic Hierarchy Process, using Microsoft Excel 2016. Findings: Among the core values of the municipal hospitals, it was shown that community linkage had the highest priority. The publicity had the highest priority among the functions and roles of the municipal hospitals. In the community care models presented in this study, the model focused on 'Community Care Integration Center' showed highest relevance, suitability and applicability. Practical Implications: This study suggested three different community care models and derived the most suitable model for community care, which is focused on the municipal hospitals. It suggested effective application of the community care model to promote community care in each community.

  • 이 연구에서는 K대학교 영재교육원의 중학교 과학영재 학생들 30명을 대상으로 빛에 관한 진단평가 15문항을 개발하여 적용하였다. 그리고 빛에 대한 학생들의 지식상태에 관하여 지식공간론을 활용하여 분석하고 이것으로부터 얻은 위계를 도식화함으로써 중학교 과학영재 학생들의 지식상태를 파악함은 물론 교수 학습 방법을 개선하기 위한 기초자료로 활용하고자 하였다. 이러한 연구 목적을 달성하기 위하여 중학교 과학영재 학생들의 빛에 대한 지식상태 평가결과를 분석하였고, 문항 간 위계구조 및 개별 학생들의 지식상태를 분석하였다. 그 결과 학습 집단 내에서 개인별로 서로 다른 지식구조를 갖고 있었고, 이에 따른 학습 진단도 서로 다르게 평가해야 함을 알 수 있었으며, 평가 문항과 문항 간의 관계(위계 구조)와 개별 학습자의 지식상태를 알 수 있게 한다는 시사점을 얻을 수 있었다.
