This study proposes a new approach which combines Data Envelopment Analysis (DEA) and the Analytic Hierarchy Process (AHP) techniques to effectively evaluate Decision Making Units (DMUs). While DEA evaluates a quantitative data set, employs linear programming to obtain input and output weights and ranks the performance of DMUs, AHP evaluates the qualitative data retrieved from expert opinions and other managerial information in specifying weights. The objective of this research is to design a decision support process for managers to incorporate positive aspects of DEA's absolute numerical evaluations and AHP's human preference structure values. It is believed that a pragmatic manager will be more receptive to the results that include subjective opinions incorporated into the evaluation of the efficiency of each DMU efficiency when the AHP and DEA are combined simultaneously. The WPDEA method provides better discrimination than the DEA method by reducing the number of efficient units.

Currently in the drought evaluation, which is a supplier-oriented standard that applies storage rates of reservoirs, evaluation for users that use agricultural water is not done. Therefore, this study established drought evaluation items for drought evaluation based on farmers' judgement, conducted a survey on farmers and experts, compared and analyzed weighted value between two groups, and then classified the evaluation standards per each evaluation item. The agricultural drought evaluation items are 5 major items of water supply lapse rate, agricultural weather, agricultural irrigation facility, crop and soil, and 12 subsections for regional characteristics and opinions of consumers that use water to be reflected. The result of analyzing weighted value of farmers and experts' major items shows that farmers is agricultural irrigation facility(0.219), water supply lapse rate(0.211), agricultural weather(0.204), crop(0.183) and soil(0.183). Experts is agricultural weather(0.297), agricultural irrigation facility(0.202), water supply lapse rate(0.189), crop(0.162) and soil(0.150), which displays difference between the two groups. The agricultural drought criteria standards are established based on precedent studies and cases, and grades of evaluation items are 1st grade(extreme stage), 2nd grade(warning stage), 3rd grade(alert stage) and 4th grade(attention stage). The above analysis per each consumer-oriented agricultural drought evaluation item and the analysis on the standards of evaluation grades are expected to be used as a basic resource for establishing agriculture drought policy and selecting drought area in the future.

Since the 30-year-old facility is expected to surge from 10.5% to 23.9% in 10 years, the new evaluation system is needed to establish efficient maintenance system for securing the safety and extending the life span of existing facilities. In this study, Delphi and AHP(Analytic Hierarchy Process) was conducted to provide a systematic new evaluation system for the NATM tunnel, which is the most frequently constructed structure of the existing tunnel. Since the existing assessment systems are limited in scope of evlauatuon criteria, the survey was conducted in conjunction with closed questionnaires on existing items and open questionnaires for eliciting new items. In results, suitable evaluation factors were derived for the NATM tunnel through the validation of the survey results. Also after calculating weighted value of the derived assessment item using AHP technique, a new evaluation system is proposed to meet the characteristics of the NATM tunnel, so that they can be used as reference materials for revising and supplementing detatiled guidelines in the future.

1980년대에서 1990년대 중반까지 건설된 노후 공동주택 단지의 주차장 부족 현상은 심각하다. 노후 공동주택의 주차장 확대 사례 를 살펴보면 수직으로 지하 주차장을 확장하는 방식이 대부분을 차지하고 있다. 기존 건축물을 증축할 경우 기초의 구조적 안전성 확보는 매우 중요하며, 지하 수직방향 공사의 경우 작업 공간이 협소하기 때문에 안전성, 환경성 및 시공성이 우수한 공법을 적용해야 한다. 도심지 공사는 소음과 진동이 작은 공법과 장비의 사용도 필수적이다. 이 연구는 지하주차장 확대 공사에 필요한 기초보강 공법 선정에 영향을 미치는 요인을 분석하고 영향요인의 가중치를 산정하여 기초보강공법의 적용성을 분석 할 목적으로 수행되었다. 기초보강 공법의 적용성에 영향을 미치는 요인은 전문가 면담조사를 통하여 도출하였고, AHP기법을 통하여 영향요인의 가중치를 산정하였다. 전문가를 대상으로 기초보강 공법의 적 용성을 평가 하였다. 2건의 지하주차장 확대 유형에 대한 사례연구를 실시하여 기초보강공법의 적용성을 비교 분석하였다.

This study proposes a selection method of a performance evaluation index of waterproofing and anti corrosion materials used in domestic water treatment facilities for material and construction failures based on different usage and environmental conditions to study the possibility of structural performance maintenance. Different types of waterproofing･anti-corrosion materials have been evaluated based on their respective properties, and have been classified into separate categories based on their case studies of material failures in construction. As a result, 12 different performance evaluation indexes have been produced for the performance evaluation method. Among the 12 performance evaluation index 5 were selected with relatively low importance that produced a low value of 60% importance using AHP analysis method, and conclusively proposed 7 performance evaluation index criteria (wet surface adhesion, fatigue resistance, crack resistance, adhesion performance, joint performance, impact resistance, impermeability)

The objective of this study was to investigate non-point sources (NPS) pollution and prioritize management areas affected by NPS pollution in the Saemangeum Watershed. AHP (Analytical Hierarchy Process) technique was selected to prioritize sub-watersheds for effectively managing NPS pollution in this study areas. Generation properties of NPS pollution, discharge properties of NPS pollution, and runoff properties of NPS pollution were selected and set for AHP. Weighted descriptors including indicators like numbers of livestock, land- and livestock-system loads, rainfall, and impervious area ratio were generalized from 0 to 1 and multiply each index based on screened 17 survey data. The results were visualized as maps which enable resource managers to identify sub-watersheds for effective improving water quality. The sub-watersheds located in Gongdeok-Myeon, Yongji-Myeon, Hwangsan-Myeon of Gimje-Si were selected for managing NPS pollution control areas. This result presented that these sub-watershed are more affected by the pollution from livestock-system than from land-system. The finding from this study can be used to screen sub-watersheds that need further assessment by managers and decision-makers within the study area.

도시환경은 비슷할 수 있지만 도시를 구성하고 있는 산업단지, 주거단지 등 모든 구조가 다르기 때문에 똑같은 재난·재해 매뉴얼을 적용하다는 것은 효과적인 재난 예방을 담보하기 어려워 위험성이 크다. 따라서 각 도시에 맞는 재난·재해 대응 매뉴얼 개발이 필요하다. 또한 한정된 자원을 효과적으로 활용하기 위하여 위험의 규모와 확률을 계산하고 지역특성을 고려한 위험 요소의 가중치 산정을 통해 집중적인 예방활동을 하는 것이 필요하다. 본 연구는 대전시의 지역별 특성에 맞는 도시 위험요소를 선정하고 우선순위 결정을 위하여 델파이 기법과 AHP분석을 이용하였다. 또한 재난·재해를 사전에 예방하기 위하여 자연재난·재해와 사회재난·재해 요인으로 구분하여 평가지표를 제시하고자 하였다. 델파이 분석결과, 대전시는 산불과 산업사고, 폭염에 대한 대비는 우수한 것으로 나타났지만 풍수해, 가뭄, 낙뢰, 교통, 건물붕괴, 독극물(환경오염), 화재폭발, 감염병 경우 ‘보통(3점)’에서 ‘그렇다(4점)’사이의 인식을 나타냈다. 반면 지진 같은 경우에는 매우 우려되고 있는 것으로 나타났다. AHP 분석결과는 풍수해, 지진에 대한 중요도가 높은 것으로 나타났다. 또한 산불재난에 대한 대비와, 건물붕괴의 중요도가 높게 나타났다. 재난·재해를 예방하기 위하여 많은 노력과 준비가 필요하지만 한정된 자원과 시간 속에서 모든 재난·재해에 비용을 지출한다는 것은 너무 많은 순손실을 가져온다. 분석결과를 기초로 도시별 재난·재해 예방을 위한 안전계획 수립, 재난대응 매뉴얼 등에 반영된다면, 재난 발생시 인구기능 밀집 등으로 인한 연쇄·증폭 효과로 심각한 피해를 보다 효과적인 방법으로 대응할 수 있을 것으로 판단된다.

본 연구는 도시지역의 내수침수 특성을 고려한 내수침수위험도 산정방법을 제시하였다. 의사결정과정에서 발생할 수 있는 불확실성을 정량적으로 반영하기 위하여 Fuzzy AHP 기법을 활용하였다. 내수침수 위험도의 평가기준으로는 물리적 지표, 사회적 지표, 그리고 내수침수 시나리오 결과 등 세 가지로 구성하였다. 각각의 평가기준은 3개의 세부평가항목을 가지고 있어 총 9가지의 평가항목을 바탕으로 내수침수 위험도 분석을 수행하였다. 또한, 행정구역 단위가 아닌 배수시스템의 노드(맨홀)를 기준으로 침수위험도를 분석하여 침수위험도가 높은 지점을 상세하게 표현할 수 있었다. 본 연구의 대상지역인 부산시 거제지구에 Fuzzy AHP 기법을 적용한 결과, 온천천 거제천 합류부 저지대의 침수위험도가 크게 나타났으며, 이는 과거 피해이력과 일치하는 것이다. Fuzzy AHP 기법을 적용한 본 연구결과는 내수침수 위험도 산정 및 고위험도 지역의 내수침수 저감계획 수립을 위한 자료로 활용될 수 있을 것이다.

The purposes of this study are to identify assessment items to evaluate riverfront for amenity and recreation and to analyze the relative importance of the items using Analytic Hierarchy Process(AHP). Total 15 items of 5 categories were identified through literature review and panel discussion. Based on the AHP analysis results, a weighted value was set for each of the layers in the hierachy. ‘Ecological Characteristics’ (0.333) was rated with the highest weighted value. followed by ‘Landscape Characteristics’(0.190) and ‘Physical Characteristics’(0.166). Among the assessment items, ‘Water Quality’ (0.152) and ‘River Naturality’(0.118) had higher weighted values. With the set of assessment items field assessments were carried out for Gyung-An Stream of Gyeonggi-Do to exam its applicability. Total 6 segments and 31 reaches out of the 22.5 km long river were evaluated and the mean scores of the five categories were converted into a percentile score for comparison. Overall, the segments which had higher scores were located close to neighborhood areas and had better connections with other historical and cultural amenities. Also, existing facilities was an important factor and needs to be considered for waterfront development.

This study aims to analyze the sensitivity of WSM(weighted scenario method)-AHP method according to variation of nonlinear exponent for accessibility criteria, which are used to make urbanization potential maps with the optimal weighting value for multiple criteria in grid-based GIS technique. Besides this study tried to develop WSM-AHP2 which is simplified by using rank of the potential value for each scenario. The two methods were applied to the test area, Suwon city located south area of Seoul, with time series land-use maps of 1986 and 1996. The evaluation system of urbanization potential have 7 criteria including 6 accessibility criteria. The results of WSM-AHP2, the optimal weighting values and their corresponding potential maps, have almost similar with those of WSM-AHP. In the application of CA(cellular automata) model for expansion of urbanized area using the three potential maps by WSM-AHP, WSM-AHP2, and specialists's AHP evaluation, it also showed that the accuracy of simulation for actual urban area is the highest in the potential map of WSM-AHP, followed by WSM-AHP2 and specialists's AHP evaluation. From the results of this study, WSM-AHP and simplified WSM-AHP2 will be used to generate the optimal potential maps for land-use planning in urban fringe area.

과거 대부분 하천에 적용된 계획하폭의 결정은 통수단면적 확보 등의 치수적인 목적만 갖고 경험공식과 기술자의 주관이나 경험적 판단으로 계획하폭을 선정하여 왔다. 그러나 현재에는 사회적, 경제적, 기술적, 환경적 요소를 종합적으로 고려된 최적의 계획하폭 선정이 요구되고 있으며, 또한 계획하폭의 계산결과에 따른 하폭거리의 다양성으로 확폭 결정시 객관적이며 정량적인 해석방법이 필요하게 되었다. 본 연구에서는 계획하폭 선정시 문제가 되는 주관적, 경험적 요소를

Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.

As one of methodological approaches for objective and systematic evaluation for rural resources, a sequential system for significance determination of resources items was formulated using AHP (Analytic Hierarchy Process) as the base technique. By the system constructed in this study, the significance values were calculated for all items of standard goal system which had been presented in the first phase- paper of research works for rural resources evaluation. The results analysed and obtained in the study are summarized as follows; 1. In case that the number of resources items for evaluation are relatively large, stepwise matrix method is considered as the better one for pair-comparison works in view of evaluator's convenience and consistency. 2. The significance valuing results for most resources items showed a considerable difference between characteristic areas, especially in aspects of land and human resources, so being considered as wet reflecting the specific areal varieties, 3. On land resources, the items for industrial development and land use showed higher significance value, while natural environment resources the items for ecological varieties and on human resources the items for artificial facilities. However, lower-valued ones were the items for mineral stocks in land resources, for control and protection in natural environment resources and for lower-level culture heritage respectively.
