In this paper we study the method to estimate weights of the elementary mathematics achievement factors to get reference index which improves elementary mathematics teaching. For it, we discuss not only a synopsis of AHP but also write out pairwise comparison matrix through statistical survey and estimate weights by eigenvector method.

According to grow interest in environmental quality with improvements of a standard of living site selection problems of environmental hatred facilities, such as waste landfill sites caused regional conflicts. This study investigates a waste landfill estimation method that was used to storage, management, analysis and display of environmental information provided by goo-spatial information system(GSIS) analytic hierarchy process(AHP) as a decision-making method. If GSIS is integrated with AHP, site selection problems of environmental hatred facilities shall be able to very useful, because of AHP with flexibility which appropriately reflect opinions of the related group.

This paper applies the Analytic Hierarchy Process(AHP) to analyzing the causes and countermeasures of the accidents by the dangerous machines. The AHP is the decision supporting tool considering several objectives and criteria, and synthesizing a number of decision makers' opinions to find the best alternative. It has the merit to be able to consider not only quantitative factors but also qualitative factors. Because this paper focuses the thoughts of the workers about the dangerous factors in working space including machines, work environment and tools, the AHP is the most suitable method for this study. This study using the AHP can be used as useful tool analyzing the important causes of the accidents by the dangerous machines and deciding the urgent countermeasures.

본 연구는 최근 수요가 급격히 증가하고 있는 CMS의 평가방법론을 개발하기 위한 목적으로, CMS와 IT솔루션 평가이론에 대한 고찰을 통해 CMS의 평가항목을 크게 "솔루션 특성", "공급벤더역량", "구매업체 환경적합성"의 대항목으로 분류하고, "컨텐츠 관리기능", "경제성", "서비스", "정보화계획적합성" 등의 총 10가지 세부항목을 제안하였다. 또한 AHP 기법을 통하여 각 평가항목의 상대적 선호도를 결정하고, 과거 단순가중치법을 이용하여 도입된 CMS구매과정과 상호비교하는 사례연구를 실시하였다. 결과적으로 과거 단순가중치법에 의해 산출된 솔루션의 평가점수와 AHP를 이용한 상대적 선호도에 따른 평가점수 사이에는 큰 차이가 존재하였다. 이 연구를 통하여 CMS 솔루션의 선정에 중요한 평가항목들을 제공하였으며, 객관적이고 과학적인 방법론인 AHP를 활용함으로써 솔루션의 차이를 효과적으로 차별화하는 좋은 사례를 제공코자 하였다.

다 단계 의사결정지원시스템, AHP(Analytic Hierarchy Process)는 다수 대안에 대하여 다 면적인 평가기준과 다수 주체에 의한 의사결정을 위해 설계된 의사결정지원방법의 하나이다. AHP 시스템은 먼저 주어진 시스템을 구성하고있는 요소를 세분하고 그 분할된 요소를 계층적으로 구성하며 다음으로 계층간 각 레벨에 있는 요소의 상대적 중요도에 대한 판단을 종합하는 과정을 거친다. 본 연구에서는 이러한 AHP방법을 실용화하기 위하여 사용자가 Web기반에서 활용하기 쉽도록 GUI-tyre 프로그램을 개발하고 이를 검증하였으며 예제를 들어 보였다. 본 연구에서 개발한 소프트웨어는 크게 다음과 같이 3 가지 구조로 구성하였다. 단계 1 : 대안 평가의 아이디어 창출 단계(Brainstorming), 단계 2 : 다 단계, 다 기준 의사결정지원시스템(AHP), 단계 3 우선 순위 종합모델(MRM)

We give a mathematical approach using Linear Algebra, especially largest eigenvalue and eigenvector on decision making support system. We find a mathematical modeling on decision making problem which could be solved by AHP(Analytic Hierarchy Process) method. Especially, we give a new approach to change evaluation indicator weight on assessing research proposals.

This research suggests the FD-AHP decision making model for Construction Projects which is composed of two main method to prevent a ranking invert situation ; First, to make the consensus of the experts consistent, we utilize Fuzzy-Delphi method to adjust the fuzzy rating of every expert to achive the consensus condition with the fuzzy linguistic presentation. Second, to handle vague linguistic presentation caused by expert's experiences and subjective judgement, we propose Fuzzy-AHP which is able to enhance precision of construction projects decision mating situation. Moreover, with the correlation analysis, we show that the validity of the FD-AHP model under a decision making task specially on where highly demanded expert's experiences and intuition.

This paper presents the Multi Criteria Decision Making (MCDM) to evaluate water resources plan for agricultural reservoir. Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE) and Analytic Hierarchy Process (AHP) were used to estimate weight and priority of alternatives to find out the most reasonable and efficient way of water resources assessment. The 6 criteria that both decision maker and beneficiary are satisfied have been identified to secure agricultural water resources and then the priority of 10 subcriteria was set. An enhanced PROMETHEE-AHP model was used to perform pairwise comparison and find out the priority of each alternative because the existing decision making model have uncertainty and ambiguity. Comparison analysis of decision making models was carried out to find a way of suitable decision making and validity of PROMETHEE-AHP model was suggested.

With the introduction of national standards (KS) for call centers, customers are expected to have access to better-quality services in the future. The purpose of this study is to evaluate the relative importance of certification criteria for call center services using the Fuzzy AHP(Analytic Hierarchy Process) approach. Fuzzy AHP is the combination of the fuzzy set theory and AHP to deal with the uncertainty or ambiguousness of the decision-making process. The evaluation method proposed in this study can be applied to the KS services certification promoted by government.

This study evaluated the importance of automobile procurement logistics using AHP. Although automobile procurement and logistics is represented by JIT, internal and external risk factors for the automobile and logistics industries are increasing, so it is necessary to re-evaluate them and establish countermeasures. Therefore, this study conducted AHP analysis targeting 30 automobile procurement and logistics experts. Through previous studies and interviews, 4 factors for Tier 1 and 12 factors for Tier 2 were derived. As a result of AHP, the logistics factor was analyzed as the most important and the cost factor was less important than the other factors. This means that supply chain operation is more important than cost, and it is analyzed that stopping all supply chain participants is more damaging than logistics or inventory costs. Such research can provide implications not only for the automotive supply chain but also other industries with similar characteristics, and it is considered to be a meaningful study at the present time when the global supply chain is being reorganized.
