Movements using aircraft are continuously increasing. This is because options for airlines, including eight national airlines, are becoming more diverse. In particular, FSC and LCC provide different services and prices, so it is not easy to choose, but it is analyzed that safety is the most important factor when selecting airlines in 2013 and 2017(all age groups are the same). There was a difference between 2013 and 2017 for each age group. In particular, the importance of price factors is high in 2017 compared to 2013, and other items in the 40s and 50s are also significantly changed.

This study analyzed the priority of decision-making attributes considered as the customers select the family restaurant with Analytic Hierarchy Process, which is the method for quantitative analysis. The result of analysis revealed that the food factor in the first stage of evaluation attributes was the most important and in the second stage, an atmosphere factor of place, an affiliated card factor of promotion, a taste factor of food and a kind attitude factor of employee were important respectively.

선박교통관제사의 자격인증 교육은 IMO와 IALA에서 권고한 교육과정, 교육과목 및 교육기간 등을 표준으로 한다. 국제적 기준이 현재 교육과 차이가 있고, 대한민국 관제사들이 생각하는 교육의 중요성에도 차이가 있기 때문에 이에 본 연구에서는 선박교통관제사 자격인증 교육 현황을 분석하고, 이를 구체적인 교과목으로 나눈 다음 기존 직원들의 의견을 취합하여 AHP 분석을 통해 상대적 중요도를 평가해 보았다.

The Analytic Hierarchy Process (AHP) is well suited to group decision making and offers numerous benefits as a synthesizing mechanism in group decisions. To date, the majority of AHP applications have been in group settings. In general, aggregation methods employed in AHP can be largely classified into two methods: geometric mean method and (weighted) arithmetic mean method. In a situation where there do not exist clear guidelines for selection between them, two methods do not always guarantee the same group decision result. Thus we suggest a simulation approach for building group consensus as a complementary tool, even when just group judgments are required. Without any efforts to make point estimates from individual diverse preference judgments, a simulation approach suggests the process how the individual preference judgments are aggregated into consensus, displaying possible disagreements as is natural in group members' different viewpoints.

Recently, the items of construction planning have magnified and specialized and the problems occurring at the first step of the construction planing process have complicated. In this research, AHP(Analytic Hierarchy Process) method which is simple to apply and clear to decide has been proposed when a people making a plan at the first step of the construction planing process. As an example, the best solution has been obtained in a railway construction line choice that consist of various items by applying for this method, which proves the possibility of application of this method to the complicated problems.

The AHP methodology compares criteria, or alternatives with respect to a criterion, in a natural, pairwise mode. AHP has been applied in a wide variety of applications multi objective decision making being just one. If a group of expert with different aspect, they need some way to revise expert group. We proposed the concatenation of expert to survey the AHP pairwise question for multi-attribute decision making. In this paper, we suggest a way to revise the expert's priorities in hierarch using concept of different group opinion.

In this research, we investigate the method to support decision making of researcher when they estimate the safety on the subway using AHP of Saaty. To apply this technique, we apply to subway system. The AHP suggested by Saaty in 1971 is a tool to support a decision-making including the personal opinion and intuition, and it is easier than other method. Then, it has an advantage that control the complex object having multiple criteria simply. And we suggest the eight stage of accident type and the five criteria that must meet. Based on AHP, we concluded a safety in subway is more important factor than any other factors including economic points of view.

It is the purpose of this study that propose method to estimate weights of decision-making for design concepts considering characteristics of places. In order to acquire these weights of concepts, the investigation with questionnaire by AHP(Analytic Hierarchy Process) is employed as a mean. Targets of this investigation was 63 respondents which were graduate students(21) and experts of design field(42). As a result, we could find differences between these weights of the relative concepts and know the differences in the weights of design concepts as characteristics of places were reflected. These weights of concepts will be take opinions about concept from design-related members into consideration. Therefore, In design process, the weights of design concepts will help for designer to verify the concepts in design initially, and finally be used by a criteria in decision-making. The Weights of decision-making for design concepts as a result of this study will be used as a guideline for the systematical and conceptual approach in design practice.

Construction automation and robotics are being taken notice as an alternative to improve productivity and quality. Reflecting on these purpose, automation system, called RCA(Robotic-crane based Construction Automation) system, is developed and have been verified through a pilot project recently in Korea. To apply the RCA system in high-rise building effectively, each management factors of element technologies in the system is derived and assessed critical factor. The purpose of this study, management factors of element techniques, consisted of RCA system, is classified through questionnaires/interviews targeting system developers and construction managers in pilot project site, and critical factors is selected using AHP.
