The purpose of this research is to propose policy of domestic timber supply expansion. To recommend polices and draw the priority orders, this study has used Delphi technique and Analytic Hierarchy Process. It has executed to recommend policies of domestic timber supply expand by dividing produce, distribution and consumption parts. As the result of Delphi technique and AHP, 'Infrastructure for domestic timber produce (.239)', 'regional domestic timber gathering complex construction (.202)' and 'a public institution domestic timber use obligation (.126)' policies are derived.

본 연구에서는 실무 및 학계에 종사하는 45명의 전문가 집단을 대상으로 쌍별비교(pairwise comparision)에 의한 설문조사에서 얻어진 전문가들의 의견을 AHP 분석을 통하여 종합하는 과정을 거쳐 부도예측모형을 설계하여 검증한 뒤, LOGIT모형과 비교하였다. 본 연구에 의하면 부도예측모형에서 정량적인 정보보다 정성적인 정보가 더 중요한 역할을 한다는 D.Bunn-G.Wright(1991)의 연구와 일치하는 결과를 얻을 수 있었다. 본 연구에서 발견된 분석결과를 요약하면 다음과 같다. 첫째로 LOGIT 모형과 AHP 모형에서 모두 정량적인 정보만을 고려하는 경우보다 정성적인 정보를 함께 고려한 모형에서 부도예측율이 더 높은 것으로 나타나고 있어 부도가능성을 예측하는데 있어 정성적인 정보가 중요한 역할을 한다는 결론을 얻었다. 둘째로 AHP를 이용한 부도예측 모형을 설계할 때 각 속성에 대한 전문가(45명)들의 의견을 종합하는 방법으로 산술평균과 기하평균을 이용한 검증결과에 의하면 기하평균방법을 통하여 전문가들의 의견을 종합하는 것이 보다 합리적이라는 실증적 증거를 얻을 수 있었다. 셋째로 Akaike의 기준값을 분석한 결과에 의하면 LOGIT 모형은 정량적인 정보와 정성적인 정보를 모두 이용한 모형이 가장 우수한 것으로 판명되었고, 모형의 부도예측력도 가장 높은 것으로 밝혀졌다. AHP 모형은 정성적인 정보만을 이용한 모형에서 가장 높은 부도예측을을 나타내었으며, 기하평균을 이용한 AHP 모형은 LOGIT 모형보다 항상 높은 부도예측율을 보여주었다.

Since the preexisting evaluation methods of landslide susceptibility take somehow long time to determine the slope stability based on the field survey and laboratory analysis, there are several problems to acquire immediate evaluation results in the field. In order to overcome the previously mentioned problems and incorrect evaluation results induced by some subjective evaluation criteria and methods, this study tried to develop a method of landslide susceptibility by a quantitative and objective evaluation approach based on the field survey. Therefore, this study developed an evaluation chart for landslide susceptibility on natural terrain using the AHP analysis method to predict landslide hazards on the field sites. The AHP analysis was performed by a questionnaire to several specialists who understands mechanism and influential factors of landslide. Based on the questionnaire, weighting values of criteria and alternatives to influence landslide triggering were determined by the AHP analysis. According to the scoring results of the analysed weighting values, slope angle is the most significant factor. Permeability, water contents, porosity, lithology, and elevation have the significance to the landslide susceptibility in a descending order. Based on the assigned scores of each criterion and alternatives of the criteria, an evaluation chart for landslide susceptibility was suggested. The evaluation chart makes it possible for a geologist to evaluate landslide susceptibility with a total score summed up each alternative score.

Nowadays, SNS media has become one of the most common and economic communication methods in the modern word. With the rapid development of communication technology, a variety of SNS media makes easier for us to reach other people everywhere and people are getting more and more reliant on them. The surge in SNS media users and SNS media diversity gets more important every day, but academic research on SNS media evaluation program is scanty. In order to present an evaluation program on the SNS media, this study selected some applicable measurement factors based on reference research, and then evaluate major SNS medias by using AHP analysis method. With these purposes, Kakaotalk, Twitter and Facebook, are the three major SNS medias that were chosen for the analysis. Through collections and analysis of usability evaluation factors about SNS quality from related literature, some factors were concluded: system quality, information quality, interface quality and service quality, to build an AHP frame. And to achieve these purposes, this study applied comprehend mutual questionnaire survey for experts and users to gather research date. Empirical studies about the results were performed using AHP method with Microsoft Office Excel 2010. In this study, the final SNS media evaluation result is that Kakaotalk ranks first of the three SNS media, Facebook is in the second place, and Twitter as least. When SNS media are evaluated, system quality, information quality, interface quality and service quality should be considered. Among all factors, service quality is the most important.

This study has intended to develop an evaluation model to select suitable locations of recreation forests in accordance with their types, and to apply the models to the feasibility study of selecting suitable recreation forest locations of candidate sites. To reach this goal, this study employed a Delphi expert survey method and Analytic Hierarchy Process (AHP) for the whole process of model building. And the followings are what this study has found during model building and application process. First, the assessment criteria for classifying recreation forests and selecting suitable locations were initially identified through justification process with two rounds of expert review, after broken down into 2 categories, and then further divided into 6 items and 12 indicators accompanying with hierarchical structure. Second, in the third phase of Delphi expert survey, the relative weights of the assessment criteria were derived by employing AHP. Through overlaying two evaluation categories including resource and usability, 4 types of recreation forest were presented. In the forth phase of the Delphi survey, this study has developed an evaluation model to select suitable locations of recreation forests in accordance with their types using relative weights of the selected indicators through. This study has applied the models to the feasibility study of selecting suitable recreation forest locations of candidate sites, and found that the usability of recreation forest was severely affected by the distance from the capital region, that the closer the locations of natural recreation forests from the capital region, the more advantageous. The developed model can be used to designate recreation forests in accordance with their types.

One of the main factors which reduces the efficiency of a sewage treatment plant is the Inflow/Infiltration(Ⅰ/Ⅰ) in the sewer First we must calculate the quantity of Ⅰ/Ⅰ via the investigation of each sewer to establish the reduction plan of Ⅰ/Ⅰ. However, in Korea, we apply the results of a surveyed sample to the entire study area to establish the reduction plan of Ⅰ/Ⅰ. This methodology just considers the total Ⅰ/Ⅰ for the entire study area but it does not consider the quantity of Ⅰ/Ⅰ for the individual sewer systems. Therefore, we may need the model to consider the Ⅰ/Ⅰ in the individual sewer systems and we develop the model to calculate the Ⅰ/Ⅰ that happen in urban sewer systems. We estimate the Ⅰ/Ⅰ of individual systems by the developed model and the estimated Ⅰ/Ⅰ are utilized as the basic data for the establishment of Ⅰ/Ⅰ reduction plan. The observed Ⅰ/Ⅰ for the entire study area is distributed into the individual sewer systems according to their defect states. Here, the weights of defect elements are calculated using AHP(Analytic Hierarchy Process) and we perform the uncertainty analysis for considering the errors using MCS(Monte Carlo Simulation).

전 세계적으로 지구온난화로 인한 기후변화의 영향으로 예측이 어려운 돌발성 기후로 인한 재난 사례가 급증하고 있다. 이처럼 재해를 유발하는 위험기상 현상의 강도는 점점 증가하지만 인구와 사회기반 시설은 한 곳에 집중되면서 지역적 단위가 아닌 지구단위 규모의 국지적 기상재해가 증가하고 있는 추세이다. 이에 따른 재해의 안전성과 취약성을 평가하는 다양한 연구가 수행되고 있으나, 대응관점에서의 성능 평가에 대한 절차와 연구는 상대적으로 미비한 실정이다. 따라서 본 연구에서는 국내외 수재해 대응 평가요소를 조사하여 도출된 대응요소의 중요도를 AHP기법을 이용하여 분석하였다.

최근 국방 분야의 모델링 및 시뮬레이션에서는 훈련 비용과 개발 비용을 절감하기 위하여 재구성 가능한 시뮬레이션 모델의 연구를 추진하고 있다. 기존 연구에서는 소프트웨어 프로덕트 라인 공학을 적용하여 BCM(Basic Component Model)을 정의하고 이들을 재구성 할 수 있는 도구를 개발하였다. 하지만 프로덕트를 생성하기 위한 컴포넌트 재구성 시 설계자의 의사를 체계적으로 반영할 수 없으며, 각각의 컴포넌트들의 정량적 요소를 비교,평가 후 컴포넌트를 선택하여 프로덕트를 구성하기 어렵다는 단점이 있다. 따라서 본 논문에서는 컴포넌트 재구성 시 설계자의 의사결정과정을 지원하고자 컴포넌트들의 메타데이터를 조사하고 계층적으로 분석하여 컴포넌트를 선정할 수 있는 방법을 제안한다. 또한 이것을 기반으로 컴포넌트 재구성 조합 모형을 도출 할 수 있도록 하는 의사결정체계를 제시한다. 먼저 의사결정의 한 방법인 AHP(Analytic Hierarchy Procedure)를 이용하여 컴포넌트를 선정하고, 다음으로 선정된 컴포넌트를 검색하고 선택할 수 있는 의사결정지원시스템을 설계 하였다.

본 연구에서는 인천 지역의 범죄의 특성 지역을 분석하기 위하여 기존의 이론적인 논의에 기초하며 AHP와 GIS와 연계를 통해 분석하고자 하였다. 이를 위해 인천의 범죄 우발지역을 볼 수 있는 공간적 패턴과 경찰서 내지 파출소의 적지를 선정하고 자료 분석 및 데이터 수집과 통틀어 공간 분석을 수행하며 이러한 분석을 통해 얻어진 여러 가지 요인들과 범죄 율을 나타내어 최종 자료를 구현하기 위한 연구를 한다. 범죄 율의 공간적 표현을 위해서 수식을 이용하여 범죄 율을 구했으며 인구 및 정확한 데이터들을 수집하여 분석하고 그대로 반영한다. AHP를 이용하여 설문조사 및 객관적인 판단과 가중치를 판단할 수 있는 중요한 척도가 되었으며, 이것들을 반영하여 최종 결과물에 현실성을 더하여, 실제로 예방조치를 취할 수 있도록 할 수 있을 것이다. 또한 GIS 소프트웨어에서 제공되는 좌표체계와 데이터베이스 및 SQL 등을 이용하여 현실성과 정밀성을 더하여 활용될 수 있음을 확인하였다.
