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.

As domestic buildings have been large-scaled, diversified and high-rise, there have been a consistent demand for design, development of construction technology and accident prevention activity as well as quality enhancement. In spite of governmental and related institutions' efforts for reducing national losses which come from numerous accidents, there have been endless small and large accidents on the construction site and thus, it is urgent to conduct empirical researches in this area. Currently safety supervision system in construction industry has enforced harm and danger prevention planning system, however it merely stick to other existing materials. In addition, it is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM(Process Safety Management) method Using AHP(Analytic Hierarchy Process) and to Development of PSM evaluation method in the construction. The reason why PSM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries,' thereby streng3thening there competitive edges. Boost of safety control system by PSM method will make an enormous contribution to preventing construction accidents on the site by establishing and securing an autonomous safety control system.

최근 정부는 수상운송기업의 경쟁력을 강화하기 위한 지원정책을 추진하고 있다. 이러한 정책을 효과적으로 수행하기 위해서는 수상운송기업의 경영성과를 평가하고 정책의 모니터링이 필요하다. 이 연구는 통합 FUZZY AHP-PROMETHEE법을 이용하여 우리나라 수상 운송기업의 경영성과를 평가하여 우선순위를 선정하기 위한 것이다. 이를 위해 먼저 수상운송기업을 7개의 대상그룹으로 구분하고, 경영성과 평가를 위한 평가항목을 추출한다. 두번째는 전문가 설문조사를 통해 Fuzzy AHP법을 이용하여 평가항목의 중요도를 산정한다. 마지막으로 평가항목의 중요도와 Fuzzy PROMETHEE Ⅱ법을 결합하여 수상운송기업군의 전체 우선순위를 결정하고 Fuzzy PROMETHEE Ⅰ법을 이용 하여 기업군간의 우선순위를 분석한다. 따라서 제안된 모델에서는 성장성, 생산성, 수익성, 기술성 등 4개의 평가 항목이 추출되었다. 그 결과 기타해상운송업의 경영성과가 가장 높게 나타났고, 내륙수상여객및화물운송업의 경영성과가 가장 낮게 나타났다. 따라서 기타해상운송업은 성과를 지속하기 위해 생산성을 증대해야 하고, 내륙수상여객및화물운송업은 성과향상을 위해 모든 항목을 증대해야 할 것이다.

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.

In this study, weight of assessment items for rock and soil slopes is deducted using AHP(Analytic Hierarchy Process). And also, weight of each performance for final evaluation is analyzed. As a result, tension crack and ground deformation make up a large proportion in all slopes, and weight of each performance based on the location of the slope does not show a big difference.

This study evaluated properties and items for selecting on a forest healing village. In order to assign a weight value-between factors, this study was conducted the primary survey first and then the secondary survey for measuring the importance of items. Experts'surveys were conducted on 3 items on level 1, 9 items on level 2, 35 items on level 3 with use of AHP technique. In level 1, the main analysis result was that physical resource properties(0.387) indicated the highest importance. in level 2, healing resources of physical properties(0.402), community participation of human resource properties(0.425), and business competency in part of vision(-.438) showed the highest importance. The analysis result of 35 items on level 3 was that in physical resources properties, securing public land in the village(0.220), possessing recreation space(0.440) and resources available for link with healing(0.413) showed the highest importance. In part of human resources properties, the average age of residents(0.465), commitment to the promotion of the villagers(0.367) and support of local leaders(0.318) showed the highest importance. Adequacy of development plan(0.274), forest work experience-related(0.293), and building profit sharing system(0.282) were also evaluated to have a relatively high importance.

Since more than 70% of our country is made of mountains, a lot of underground facilities and tunnels are used for efficient use of limited land space. Recently, Shield TBM method has been used a lot since 1980. In this paper, we selected add factors for Damage factors of shield TBM method. And we analyzed weighting factors using AHP method.

In this study, the risk factors which derive from the ground condition of typical construction sites are put forward. In order to prioritize the risk elements, the analytical method of AHP was used. The result of using a weighting factor for each risk analysis showed that if the constituency index is less than 0.1, then reliable results and priorities for each of the risk elements can be calculated using the AHP method. From now on, if the range of measured value can be established, the risk or safety value of concrete structures for power lines can be applicable.

항만의 생산성 및 효율성에 대한 관심이 증대되고 정부주도의 항만관리와 운영체제에 대한 비효율성을 개선하기 위하여 항만공사제도의 도입이 국내 외적으로 보편화되었다. 국내에서도 2003년 항만공사법이 제정되어 2005년 7월에 인천항만공사가 출범하였다. 본 연구는 인천항만공사의 설립 목적을 극대화하기 위하여 SWOT/AHP 분석기법을 이용하여 인천항만공사의 강점, 약점, 기회, 위협요인을 파악하고 우선순위별로 인천항만공사의 발전 방안을 제시하고자 하였다. 분석의 결과 인천항만공사는 사업영역확대 및 성장가능성, 인천항의 지리적 우수성 등의 강점을 확보하고 있으며, 황해권 물동량의 지속적 증가, 자유무역지대의 확대지정 등의 기회요인을 가지고 있다. 반면 정부의 투-포트시스템 정책, 중국 의존성의 가속화 심화, 국내 외 경쟁항만의 급부상 등 위협요인과 인천항만시설의 노후화 가속, 부족한 항만배후부지 등의 약점요인을 가지고 있다. 이러한 SWOT분석 결과를 근거로 계층분석적 의사결정(AHP) 방법을 이용하여 인천항만공사의 발전 방안인 S/O 전략, W/O 전략, S/T 전략, W/T 전략을 제시하였다.

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.
