  • 제품의 정성적 품질평가에서, 제품의 최종품질을 구성하는 다수의 특성에 대한 만족도가 언어로써 표현되어 소비자의 구매행동이란 의사결정으로 표출되는데, 이러한 주관적 평가에는 평가의 애매함(fuzziness)이 수반되므로 품질의 평가구조를 합리적으로 파악하기 위해서는 애매함의 존재를 고려에 넣지 않으면 안된다. 다수의 품질특성이 계층적(hierarchical)인 구조로 연결되어 최상위 품질특성으로 구성되며, 특성간의 중요도(relative importances)가 계층별로 결정되는 경우, 이들 개개의 특성에 대한 만족도의 평가로부터 어떤 구조적인 관계를 통해 그 제품에 대한 종합평가가 이루어지나, 개개의 특성에 대한 평가가 애매한 이상 최종 결과인 종합적 만족도도 애매한 것으로 된다. 즉, 평가모델의 구조도 평가의 패턴도 퍼지화되므로 이러한 평가에서 퍼지이론의 응용에 따른 효과를 가장 크게 기대할 수 있는 퍼지추론모델을 이용하여 계층간, 품질특성간의 퍼지관계와 특성의 중요도 및 언어변수(linguistic variables)의 형태로 주어지는 입력정보로써 품질구조를 명확히 하고, 패턴인식(pattern recognition)의 개념을 이용하여 평가자의 제품에 대한 평가결과를 언어로써 표현한다.

  • The Analytic Hierarchy Process (AHP) has been widely used as a comprehensive evaluation method since it can include various evaluation standards of both the public and private sectors. It also provides the objective mathematics to process subjective and Personal preferences of an individual or a group in making a decision. This study tried to use AHP to determine the priority of roads investment, considering various effects in a hierarchy such as environmental effects, residential life, and regional development which has not been treated explicitly. As a case study, roads in Gyeongsangbukdo province have been chosen for the evaluation in this research. For the application, it used relative measurements to estimate the weight of upper level structure, and absolute measurement for low level structure instead of pairwise comparisons.

  • In urban declining areas, the population is decreasing, and drying environments such as buildings and facilities are aging. Therefore, it is vulnerable in the event of disaster, and recovery takes a lot of time and money. The purpose of this study is to develop an evaluation technique for comprehensively diagnosing disasters in declining areas and to present implications through case analysis. Evaluation indicators were selected to calculate the comprehensive diagnosis index of disasters, and weights were calculated for each class, including disaster types, components, and evaluation indicators, through Analytic Hierarchy Process analysis. The comprehensive diagnoses index for each type of disaster was calculated with the calculated weight, and the risk according to the level of urban decline was analyzed. As a result of analyzing Seoul as a case area, it was analyzed that the overall risk of disasters was high in southern regions such as Seocho-gu, Dongjak-gu, Geumcheon-gu, and Gangseo-gu, and relatively low in downtown and northern Seoul, parks and green areas. The results of this study are of academic significance in that they presented a comprehensive diagnostic index evaluation system and technique for each type of disaster, including natural and social disasters.

  • The final goal of this study was to develop an optimal service scenario to ensure that building occupants can be effectively evacuated from the building within the golden time without extra assistance in preparing and evacuating for fires. In addition, the research was carried out by dividing the current services into fire evacuation and preparedness phases by applying the Double Diamond process in order to find a way to better familiar them as a lifestyle and to always be prepared for fires. For the building occupants and managers, a total of 14 ideas were first suggested, including not only the services of how to evacuate from a fire, but also the life-style service functions associated with fire implementation technology in daily life. The 14 proposed ideas were conducted by the Service quality evaluation and Analytical Hierarchy Process(AHP) from the perspective of the service recipient, and those were finally prioritized from the service provider's perspective, taking into account the cost and practicality of the service provider. The results of this study show that differences in the importance of fire phases considered by stakeholders and the perception of fire generally vary considerably.

  • Annual reports on the ease of doing business, published from the World Bank, measure the regulations of economies that enhance business activity and those that constrain it by the 10 areas of business life-cycle. It then calculates the scores and ranks in each of the areas and in aggregate. The aggregate scores are the summation of the scores in the areas. This means that all the areas have the same weight. As evaluation results can vary greatly by the areas used and their weights, it is possible that the areas emphasized by small and medium-sized enterprises(SMEs) of Korea are not appropriately reflected in the evaluation results. From the viewpoint of small and medium-sized Korean enterprises, this paper tries to compare the ease of doing business of economies via determining the weights of the 10 areas. Through an AHP-based survey on Korean professors of a business school and SME CEOs, the weights are determined and then applied to the calculation of the aggregate scores and the ranks of the economies. While the changes in the top and bottom ranks are relatively small, some cases of big changes are found in the middle ranks.

  • In this study, for the application of land resource evaluation using GIS map overlay method, I have considered about the process that can draw out right results from the problems involving multiple hierarchical indicators and weights. The assumption of this research is that there are two processes in the application of analytic hierarchy process(AHP) and the different results will appear. The two processes are as follows; (1) calculate directly the comprehensive weights to the indicators and overlay the layers(Method I) and (2) repeat the process of map overlay and standardization(Method II). The two precesses are applied on the study site based on the envirosystem in Bong-Hwa, and then some differences were found in the results and it was suggested that the Method II is more reasonable.

  • The purpose of this study was to evaluate the relative weight of infectious disease vulnerability indicators that affect the occurrence and spread of infectious diseases in local communities. For this, the infectious disease vulnerability indicators were classified as facilities vulnerable to spread, vulnerable groups of infections, social vulnerable conditions, and response capabilities based on literature and case review, and the relative weights among indicators were determined using Analytic Hierarchy Process(AHP) by 22 experts. As a result of the analysis, the weight of each sector was found to be the highest in the facilities vulnerable to spread, and the overall weight was highest in the following order: sickbed securing rate(1st), density of religious facilities(2nd), medical personnel rate(3rd), elderly person ratio(4th), and entertainment establishment density(5th). These results can be used to prepare the supporting data necessary for the establishment of infectious disease response policies of local governments.

  • This study examines the mobility of the disadvantaged population groups in terms of public transportation using the 2014 smart card data in Seoul, Korea. Particularly, we focus on the disadvantaged population such as senior group, junior group, and low-income population group. Based on the spatial distributions of public transportation mobility levels and the disadvantaged population groups, we identify specific areas where public transportation service should be improved for the disadvantaged population. As a result, we identify 15 administrative-dongs where the ratio of the disadvantaged population is high while the mobility index of public transit is low. The main contributions of this study are as follows. First, we use the smart card data which contains the information of actual trip made by individuals and develop the evaluation process of urban mobility for the disadvantaged population groups. Second, we identify the specific areas where public transportation service should be improved for the different group of the disadvantaged population. Lastly, we discuss policy implications to improve the urban mobility of the disadvantaged population.

  • 동일하거나 유사한 기능을 수행하는 소프트웨어 제품들 중에서 사용자 요구사항에 가장 적합한 제품을 결정하기 위하여 측정과 평가 및 선정을 실시하는 것을 매우 중요한 일이다. 이러한 소프트웨어 제품의 평가와 선정은 대량 구매시 객관성 확보를 위해 특히 중요하다. 소프트웨어 제품의 평가를 위한 절차는 평가 대상 제품의 속성 결정과 측정, 속성의 중요도에 따른 가중치 부여, 그리고 평가와 선정 모형을 통한 최적제품의 선정이나 우선순위의 결정이다. 본 연구에서는 이러한 절차에 따른 가중치 부여 방법으로는 계층적 분석과정을 이용하고, 제품의 평가와 선정 방법으로는 4개 보상모형과 7개 비보상모형, 그리고 4개의 DEA(Data Evelopment Analysis)모형을 종합적으로 설명한다. 또한 본 연구에서는 위의 15개 평가와 선정모형을 사용하여 Infoworld(Jan.1997)에서 발표한 '문서 작업흐름 관리' 소프트웨어 제품의 속성에 대한 측정결과를 가지고 모형별 적용 결과를 분석한다.

  • 본 연구는 OTT 서비스에 대한 선택요인들을 기존 연구를 바탕으로 도출하고, 각 평가 요소에 대한 가중치를 산출하기 위하여 AHP 분석모형을 제시하였다. OTT 서비스를 이용하는 고객들을 대상으로 수집된 자료를 분석한 결과 먼저 OTT 서비스의 1단계 선택요인에서는 다양성이 중요한 요인으로 나타났다. 그리고 각 단계별 가중치를 종합화한 결과에서는 오락이 가장 중요한 요인으로 나타났다. 이를 통해 소비자들이 OTT 서비스를 이용할 때 어떤 요인을 중요하게 고려하는지를 파악할 수 있을 것이다.
