PURPOSES : The purpose of this study was to investigate directions for future smart city transportation policies and service development by evaluating road service satisfaction levels and predicting future service demand. METHODS : A nationwide survey was conducted in Korea to develop a transportation service evaluation system based on the functions and objects of transportation. The satisfaction level of road service was evaluated using an analytic hierarchy process (AHP), promising service sectors were identified using the revised importance-performance analysis (IPA) technique, and detailed service demands by sector were suggested. RESULTS : The most valuable service value felt by the people was "safety" (weight 0.4), and the overall satisfaction level was 68.9 points, slightly exceeding "normal." As a result of analyzing the promising service sectors by dividing them into urban and rural areas, "handicapped, elderly, and pedestrians" were important in both areas, and "road facility maintenance" was classified as an additional promising sector for rural areas. CONCLUSIONS : People demand that future smart city transportation policies and services should be "people" and "safety" centered. In addition, it is necessary to pay attention not only to the development of new services but also to the improvement of problems with existing services and policies.

The railroad facilities are intended for long-term operation as the initial acquisition costs necessary for infrastructure construction are high. Therefore, regular maintenance of railroad facilities is essential, and furthermore, system reliability through systematic performance evaluation is required. In this study, the signal control system of railroad electrical equipment was selected as the subject of research and the performance evaluation target facility selection study was conducted using AHP. The results of the study can contribute to the reliability of the signal control system as well as to the reliability of the railroad system, which is a higher system.

Failure mode and effects analysis(FMEA) is popular approach applied to examine potential failures in equipment designs and maintenance of equipments. Risk Priority Number(RPN) is used as an index for the criticality of fault modes in FMEA and RCM(reliability centered maintenance). Traditional RPN approach does not have much credit as a index for the criticality because it does not reflect their experience and the governing logic is apart from their knowledge. Multiple Criteria Decision Method(MCDM) is a proven approach applied to evaluate multiple conflicting criteria in decision making. MCDM can be applied as a tool for RPN evaluation. This study was carried out to investigate application of Analytical Hierarchy Process(AHP) in evaluating RPN.

Recently the concentration of fine dust and ultra fine dust becomes so bad, which seriously threatens the health and even the life of people. So, government started to investigate several ways to reduce the amount of fine dust and ultra fine dust. From a few years ago it has been known that ships anchored at port emit a lot of pollution and seriously affect air quality of neighboring cities. To reduce the pollution emitted by ship AMP (Alternative Maritime Power Supply) has been proposed, which uses the electricity instead of bunker C oil or diesel. Many developed countries already installed AMP to improve air quality in port area. Korea is in the stage of planning to install AMP at port. However, there are many complicated problems to be handled before AMP installation. Due to huge initial cost and long period of construction ship owner and habour operating company are reluctant to AMP installation. And there are serious technological difficulties in constructing AMP in existing harbour. Lack of AMP core technology and operational difficulties of AMP are also big challenges to be conquered. In this study SWOT/AHP method is used to find strategic and efficient ways to handle above complicated challenges and then to vitalize the AMP installation.

The CNC machine tool field is showing a growing trend with the recent rapid development of manufacturing industries such as semiconductors, automobiles, medical devices, various inspection and test equipment, mechanical metal processing equipment, aircraft, shipbuilding and electronic equipment. However, small and medium-sized machining companies that use CNC machine tools are experiencing difficulties in increasingly intense competition. Especially, small companies which are receiving orders from 3rd or 4th venders are very difficult in business management. In recent years, company S experienced difficulty to make product quality and delivery time due to the ignorance of the processing method when manufacturing cooling plate jig made of SUS304 material used for cell phone liquid crystal glass processing. In order to solve these problems, we redesigned the process according to the size of our company and tried to manage all processes with quantified data. In the meantime, we have found that there is a need to improve the cutter process, which accounts for most of the machining process. Therefore, we have investigated the correlation between RPM and FEED of three cutters that have been used in the past. As a result, we found that it is the most urgent problem to solve the roughing process during the cutter operation which occupies more than 70% of the total machining. In order to shorten the machining time and improve the quality in machining of SUS304 cooling plate jig, we select the main factors such as price, tool life, maintenance cost, productivity, quality, RPM, and FEED and use AHP to find the most suitable milling cutter. We also tried to solve the problem of delivery, quality and production capacity which was a big problem of S company through experiment operation with selected cutter tool. As a result, the following conclusions were drawn. First, the most efficient of the three cutters currently available in the machining center has proven to be an M-cutter. Second, although one additional facility was required, it was possible to produce the existing facilities without additional investment by supplementing the lack of production capacity due to productivity improvement. Third, the Company’s difficulties in delivery and capacity shortfalls have been resolved. Fourth, annual sales increased by KRW 109 million and profits increased by KRW 32 million annually. Fifth, it can confirm the usefulness of AHP method in corporate decision making and it can be utilized in various facility investment and process improvement in the future.

Due to the rapid change of global business environment, the growth of China’s steel industry and the inflow of cheap products, domestic steel industry is faced on downward trend. The change of business paradigms from a quantitative growth to a qualitative product is needed in this steel industry. In this environment, it is very important for domestic steel distribution companies to secure their competitiveness by selecting good supply companies through a efficient procurement strategy and effective method. This study tried to find out the success factors of steel distribution industry based on survey research from experts. Weighted values of each factors were found by using AHP (analytic hierarchy process) analysis. The weighted values were applied to DEA(data envelopment analysis) model and eventually the best steel supply company were selected. This paper used 29 domestic steel distribution firms for case example and 5 steps of decision process to select good vendors were suggested.This study used quality, price, delivery and finance as a selection criteria. Using this four criterions, nine variable were suggested. Which were product diversity, base price, discount, payment position, average delivery date, urgency order responsibility and financial condition. These variables were used as a output variable of DEA. Sales and facilities were used as an input variable. Pairwise comparison was conducted using these variables. The weighted value calculated by AHP pairwise comparison were used for DEA analysis. Through the analysis of DEA efficiency process, good DMU (decision making unit) were recommended as a steel supply company. The domestic case example was used to show the effectiveness of this study.

Various kinds of processes are used in the Public Sewage Treatment Works(PSTWs) in order to achieve water quality criteria and TMDL in the watershed. The performance of the existing processes at PSTWs depends on influent characteristics, effluent quality target, amount of sludge production, power cost and other factors. In present, the Selection Guideline for the Available Treatment Process of PSTWs is used for a process decision in the country. But there are some problems regarding redundancy of assessment factors and complexity of assessment procedure in the guideline. In this study, we did a test application of AHP for process selection of PSTWs, which propose is to simplify assessment factors such as pollutant removal amount, sludge generation, electricity consumption, stability of operation, convenience of maintenance, easiness of existing process application, installation cost, and operating cost concerning of environmental factors, technical factors and economical factors. According to the study, the PSTWs selection procedure guideline can be improved using application of AHP method.

Recently, conservation and utilization of cultural heritage has been regarded as importance. So, various research papers about maintenance of the remains have been presented in many conferences. But most of researches have focused on introduction about maintenance methods and explanation about maintenance concepts of remains. And even in case of a few papers treated post-evaluation about maintenance of the remains the criteria of the evaluation has tended to somewhat subjective. So, the purpose of this study is to show the objective post-evaluation indexes which was developed by Delphi · AHP methods. This research was proceeded in two stages. First, we arranged the evaluation index in a hierarchy to be made through the analyses about references and researches about maintenance of remains. 304 evaluation articles were elicited through the process. And then, elicited evaluation articles were classified with 'conservation' and 'utilization'. Second step was to figure out importance and validity of hierarchical evaluation articles with twice questionnaire surveys. This research used interval scale to comprehend validity and AHP method to evaluate relative importance of each other articles.

교량공사는 지상작업과 고소작업이 혼재하고 작업공종이 복잡하여 위험성이 높은 공사로 추락, 협착, 붕괴, 낙하 비래 재해의 발생빈도가 높다. 또한, 중량 부재의 운반, 조립, 양중 등의 작업과정에서 유해 위험 기계기구와 건설장비 사용에 따른 유해 위험 요인이 산재하여, 유해 위험의 정도와 재해 발생빈도 및 재해의 강도에 차이가 있어 위험성평가를 통한 정량화된 위험지수의 제시가 필요하다. 위험성 평가는 교량공사의 특성을 고려하여 교량 건설현장의 공종별 유해 위험요인을 세부공종별 요소작업에 따라 분류하고, 재해 발생정도와 피해정도에 따른 위험도가 평가되어야 한다. 이러한 교량 건설공사의 재해를 줄이는데 기여할 수 있도록 정량화된 교량공사 위험지수를 제시함으로써 체계적이고 효율적인 재해예방 활동에 필요한 기초자료를 제공할 것이다. 특히 교량공사 시공 상의 제반 위험요인을 사전에 점검하여 변경 보완 제거할 수 있는 재해 예방대책을 수립하여 재해를 최소화하는 연구가 필요하게 되었다. 건설현장에서 위험지수의 고저에 따라 자원을 적정하게 배분한다면 안전관리의 효율성이 제고되고, 궁극적으로 건설재해 감소에 기여하게 될 것으로 기대된다.

본 연구는 최근 정부 및 지자체에서 다양하게 추진하고 있는 각종 지역개발사업의 효율적 추진을 위해서 농산촌지역의 지대구분 및 사업추진을 위해 농산어촌지역 지대구분을 위한 구분기준과 지표를 개발하고 지대구분 안을 도출하는 것이 목적이다. 연구결과, 도시화지역 6개 읍․면, 준도시화 지역 13개 읍․면, 농촌지역 14개 읍․면, 중산간지역 18개 읍․면, 산간지역 11개 읍․면으로 구분되어 전체적으로 균등한 분포를 나타냈다. 세부적으로 보면, 각 군의 읍지역과 중심기능을 담당하고 있는 일부 거점면이 도시화지역으로 분류되었으며, 반대로 지형적으로 다소 산간지역의 특성이 강한 지역일지라도 수려한 자연경관 및 우수한 관광자원을 보유한 지역의 경우에 평가량이 다소 높게 나타난 것이 특징이다. 결과적으로 같은 군에 위치하거나 인접한 읍․면일지라도 각 읍․면별 지역적 특성은 서로 다른 특성을 내포하고 있기에 당해지역의 발전 잠재력을 극대화 할 수 있도록 지역적 특성을 고려한 사업추진이 절실하게 요구되고 있다.

도로건설사업에서 정책적인 의사결정이 필요한 경우, 다기준 평가방법인 AHP로 전문가 설문조사를 통한 정책적 분석을 시도하였다. 그러나 PI 제도 도입에 따라 도로관련 전문가뿐 아니라 지역주민, 환경단체 등 여러 관련 그룹의 다양한 의견이 제기되므로, 그룹간 의견을 종합하는 것이 필요하다. 본 연구에서는 도로건설사업의 PI 제도 운영실태를 연구 사례로 하여, AHP모형의 가중치 계산과정에서 각 그룹별로 설문조사한 자료를 이용하여, 의사결정과정에서 그룹별로 어떤 요인들을 중요시하는지 그룹별 AHP 분석을 시행하고, 그룹별 가중치가 반영된 통합 결과와 비교평가하였다. 분석결과, 그룹간 평가항목에서 분산분석(ANOVA)에 유의한 차이가 있는 것으로 분석되어, 각 그룹마다 중요하게 여기는 평가항목의 우선순위가 상이함이 확인되었다. 종합평가 결과 평가대안은 동일한 결과를 보였으나, 첫째, 그룹간 AHP 분석결과 전문가 그룹과 주민 그룹간, 전문가 그룹과 시민단체 그룹간에 유의한 차이가 있어, 그룹별 평가 필요성이 제기되었다. 둘째, 통합평가를 위한 그룹간 평가가중치 산정결과에도 현저한 차이가 나타났으며, 가중치를 고려한 AHP분석방법이 다양한 그룹의 의사결정 지원도구로 활용될 수 있다고 판단된다.
