본 연구에서는 안성시(520 ㎞2)를 대상으로 Logistic 회귀분석 방법과 AHP 기법을 이용하여, GIS와 RS 자료를 활용한 산사태 위험지를 분석하였다. Logistic 회귀분석과 AHP 기법에는 6개의 인자(경사, 경사향, 고도, 토양배수, 토심 , 토지이용)를 사용하여, 7등급으로 산사태 위험도를 분류하였다. Logistic 회귀분석 방법과 AHP 기법을 이용한 산사태 위험지도를 표본 자료와 비교하면 산사태가 발생한 표본에서 산사태 위험성이 높은(1-2등급)지역이 Logistic 회귀분석에서는 46.1% AHP 기법은 48.7%로 분류되어 AHP 기법이 분류도가 높다고 분석되었다. Logistic 회귀분석과 AHP 기법은 서로 분석 과정의 차이를 가지고 있기 때문에 Logistic 회귀분석과 AHP기법을 적용한 결과에 동일 가중치를 부여한 후 7개 등급으로 재분류 (reclass)하여 산사태 위험지역을 추출할 수 있는 방법론을 본 연구에서 제시하였다. 그 결과 산사태가 발생한 표본에서 1-2 등급지역이 58.9%로 분석되어 분류정확도를 높일 수 있었다. The objective of this study is to analyze the landslide hazard areas by combining LRA (Lgistic Regression Analysis) and AHP (Analytic Hierarchy Program) methods with Remote Sensing and GIS data in Anseong-si, In order to classify landslide hazard areas of seven levels, six topographic factors (slope, aspect, elevation, soil drain, soil depth, and land use) were used as input factors of LRA and AHP methods. As results, high-risk areas for landslide (1 and 2 levels) by LRA and AHP of its own were classified as 46.1 % and 48.7%, respectively. A new method by applying weighting factors to the results of LRA and AHP was suggested. High-risk areas for landslide (1 and 2 levels) form the new method was classified as 58.9%.

한중근,이종영 한국지반공학회 2008 한국지반공학회논문집 Vol.24 No.8

In this study, to determine the priority of the effect factors and the preferences of commonly used reinforcing methods for the cut-slope, the reasonable analysis using AHP technique was performed. Analytic Hierarchy Process (AHP) technique is the most widely used method out of all existing decision making methods. On choosing the methods, the most important factor is analyzed to be the stability and durability. Stability, durability and environmental compatibility took up over 50% of the total contributing factors. Cut-slope reinforced method preference with increasing stability method confirmed that concrete retaining wall, reinforced-soil wall and cutting method showed the highest preference rate. Also, in practical field conditions, the cutting method out of four methods was chosen to be the most effective method. This reflected that the methods that are equally superior in all aspects of evaluation factors are more important than the methods with superiority in highly prioritized evaluation factors.

정장면,김철 한국방재학회 2011 한국방재학회논문집 Vol.11 No.3

하천을 설계할 때 적절한 호안공법을 선정해야 하지만 이에 대한 가이드라인이 없는 실정이다. 따라서 하천설계시 채택한 호안공법들의 적합성 여부를 판단함으로서 예산의 낭비를 막을 필요가 있다. 본 연구에서는 하천설계시 채택한 호안공법들이 적합한지를 평가하는 방법을 개발하고, 이를 8개 하천에 적용함으로서 개발된 방법의 타당성을 검토하였다. 평가방법은 계층화분석법(AHP)을 사용하였으며 각 하천에 적용된 호안 공법의 적합도(SI)를 분석하여 평가하는 방법을 사용하였다. 최적 호안공법이 선정되기 위해서는 설계대상지점의 모든 환경변수가 고려되어야 할 것이다. 따라서 설계호안을 평가하기 위해서도 대상지점이 가지고 있는 모든 변수가 포함되어야한다. 호안평가항목은 호안의 수리적 안정성, 환경생태성, 경제성, 어메니티의 4가지 항목을 사용하였으며 각 항목은 4~5개의 소항목을 포함하며 각 소항목은 대상지점의 조사결과를 반영한 자료이다. 평가방법은 8개 하천을 대상으로 적용되어 평가되었으며 설계된 호안의 SI를 판정하였다. 본 연구의 결과는 특히 자연친화적인 호안공법을 평가하는 데 적합할 것으로 생각되며 부적절하게 설계된 호안은 적절한 공법을 선정하는데 도움을 줄 수 있을 것이다. When designing a river, it is important to select the appropriate bank revetment methods, but there are no specific guidelines until now. Accordingly, it is important to prevent over-budgeting by deciding the suitability of the adopted bank revetment methods when designing a river. In this study, an assessment method was developed to assess the suitability of the adopted bank revetment methods when designing a river. By adopting this method to eight rivers, its validity was examined. Analytic Hierarchy Process (AHP) was used for the assessment, along with suitability index (SI) of the adopted bank revetment methods when designing a river. In order to select the best bank revetment methods, all environmental variables of the selected location have to be considered. Accordingly, to assess the designed bank revetment methods, all variables of the selected location have to be considered. The assessing items include hydraulic stability, environmental-ecological feasibility, economy, and amenity of the bank revetment. Each item includes four to five sub-items, and each sub-items reflect survey results on the locations. The assessment method was adopted and assessed for eight rivers, and bank revetments was designed to determine the SI. The result of this study is considered to be appropriate when assessing an eco-friendly bank revetment methods, and inappropriate designed bank revetments will guide future planners for selecting the most appropriate construction method.

(Background and Purpose) As the phenomenon of urban population density continued amid accelerated urbanization and industrialization from the late 20th century, numerous experts related to urban movement began to seek ways to sustainably develop the urban environment. Among them, public spaces have emerged as the most important concept in building an urban environment. As interest in health has increased due to COVID-19, urban residents have become more interested in fitness parks in urban public spaces as they value the location of the natural environment. Therefore, it is necessary to recognize the importance of public space evaluation criteria and reset the evaluation ranking of public design to reflect the needs of urban public fitness park users. The purpose of this study is to present the evaluation criteria and design principles of public spaces by deriving the evaluation items for the fitness public space through the analytic hierarchy process (AHP) technique, experts, and identifying the importance ranking of the factors affecting the evaluation of urban fitness parks. (Method) This study identified the concept of related variables through theoretical considerations and preliminary surveys and established an AHP model. For the professionalism of the study, spatial design experts were invited to conduct a survey, and the ranking of urban public space evaluation items and urban fitness park evaluation criteria were presented through the AHP analysis technique. (Result) Accessibility, usability, safety, aesthetics, comfort, and diversity, which are the evaluation items of urban parks, greatly affect the public space of fitness users, while variability, sustainability, sharing, and locality do not affect user satisfaction. In addition, the importance ranking of the evaluation items through the AHP analysis technique was in the order of safety> comfort> accessibility> aesthetics> usability> variability> commonality> sharing> domain. (Conclusion) Through the AHP technique, this study and experts of public design derived evaluation items for fitness public spaces, and presented evaluation criteria for public spaces by identifying the importance ranking of the influencing factors on the evaluation of urban fitness parks. Therefore, by using the top evaluation items, derived as a result of the study, it will be possible to meet user needs, thereby, enhancing the positive evaluation of public spaces of urban park users.

Hongsen Luo,Yong He,Guohui Li,Ji Li 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.3

There are several factors influencing the slope stability of open pit mine, and the common methods can be divided into the subjective weighting method and the objective weighting method. In this paper, we make comprehensive evaluation of slope stability by using AHP method and entropy weight method. First of all, we make evaluation of the first level indicators, using AHP method to determine the weight of factors and then use the entropy weight method to calculate the influence factors, the conclusion has certain reliability and scientific nature. Through field monitoring, we get the membership function of each influence index by using assignment method and trapezoid distribution. Following the principle of maximum membership, slope II is the most stable, followed by slope V and slope I, slope III and slope IV are poor stability. This result is consistent with the on-site inspection, and then we proposed treatment measures according to the engineering practice.

Recently, for the purpose of choosing reasonable and economical construction, the decision making analyses, such as VE (Value Engineering) and LCC (Life Cycle Cost), are generally performed. But, these methods have some limitations for the application to subway tunnel construction method. So, the AHP (Analytical Hierarchy Process) analysis is applied to determine relative importance for obtaining objectivity in quantitative analysis. And, the LCSC (Life Cycle Social Cost) method is developed to account for the social loss and risk by tunnel construction. From the case of the subway lot, those methods are very useful to decision making analysis. And, in that case, both quantitative and quantitative analysis appraisement, the drilling and blasting method is evaluated useful alternative proposal in comparing with the cut and cover method. 지하철 터널의 합리적인 건설공법 채택을 위해 최근 건설공법의 선정에 적용되고 있는 VE 및 LCC기법의 문제점을 분석하여 개선안을 도출하고자 정성적인 분석에 있어서 AHP기법을 통한 가능한 여러 대안들간의 상대적 중요도를 결정하는 방식으로 객관성을 확보하고자 하였다. 또한, 정량평가에 있어서는 경제적인 터널구조물 건설을 목적으로 설계단계에서 기존 LCC 기법에서 고려하지 못하는 건설공사에 따른 사회적 손실을 비용으로 환산하는 LCSC 평가기법을 제안하였다. 실제 지하철 ○○공구에 적용사례를 통해 그 효용성을 검증하였으며, 검토결과 해당 공구에서는 정성평가 및 정량평가 항목 모두에서 개착공법 보다는 터널공법의 채택이 합리적인 대안으로 평가되었다.
