Unlike the existing subway service evaluation system, service evaluation indices by travel section in 26 subway stations were developed and appraised. Travel sections were classified into (1) subway station approach, (2) from entrance to platform, (3) platform, and (4) passageway for transfer, after which weights by travel section and by service evaluation index were estimated using analytic hierarchy process (AHP) by transportation experts. Subway service satisfaction data was gathered from 2000 passengers at the 26 subway stations. The results showed that the weights of (1) subway station approach and (4) passageway for transfer were highest and the weights by travel sections were different if kinds of services were the same. Comfort on the platform, crowdedness in the passageway for transfer, and transfer information from entrance to platform were highest in order in terms of satisfaction. Meanwhile, the results of the IPA showed that services in the passageway for transfer were high in terms of weights but were relatively low in terms of satisfaction. Therefore the services in passages for transfer needed to be reformed preferentially.

Recently, various renewable systems have been developed and applied in Korea. However, there are many systems which were not utilized in real buildings or not widely spread in the market. Furthermore, the attention of most users focused on several certain system such as PV or solar system. Therefore, this research aims to find user's needs for renewable energy based on perception surveys to improve the acceptance of technology in line with the world's energy flow. The survey was conducted by classifying respondents by various criteria, and the results were analyzed using AHP technique and CVM technique, focusing on preference and acceptance. According to the results of the survey, it was found that the people felt the need for renewable energy but lacked knowledge about renewable energy compared to the various government-implemented renewable energy supply policies. Therefore, a government-level policy is needed so that the people can have universal knowledge about renewable energy system.

Existing railway bridges have been going through various improvements since the past, with new improvement plans being formed based on social and technological demands. However, there is the need, above all, for an efficient execution plan due to the great number of sites and excessive amount of required expenses contrary to limited assets. The system itself must be held in question in order to systemize various improvement plans, to define and describe factors while utilizing evaluation methods for significance and correlation to achieve generalization. This paper is focused on determining the priority of various improvement plans through the optimization selection process of mutually evaluating alternative plans under various evaluation standards, thus corresponding to the decision-making purpose. The AHP analysis technique was applied for systemization setting and preference evaluation, while the HPT procedure was applied to develop and select appropriate improvement plan factors.

The objective of this study is to analyze domestic air passengers' preferences for selecting domestic airline company. By the analytic hierarchy process(AHP) method, we tried to measure the weight of the qualitative factors objectively and scientifically. The overall results indicate that domestic air passengers place more weight on airport service factor than other service factors for selecting domestic airline. Also, reservation/ticketing and in-flight service factors are equivalent to airport service factor. These priorities are differently shown followed by passengers' income. Therefore, airline companies need to formulate the differentiated strategy and customer-oriented marketing plan based on identified customer needs.

With the enforcement of the infrastructure management act, the importance of utility tunnels that jointly accommodate life-lines such as electricity, communication, water supply, and heating facilities has increased. The currently applied utility tunnel maintenance system is managed in an accident-preventive safety-based evaluation method. However, this evaluation method has limitations in effective maintenance. In this study, performance evaluation items were derived through the Delphi method to suggest a criterion for quantitatively evaluating the performance of utility tunnels, and the weights for each item were calculated through the Analytic Hierarchy Process (AHP) method. In the future, it is judged that a more reasonable performance evaluation standard of utility tunnel can be prepared if modifications and supplements are made through field application.

There has been a lot of researches on the major motivation of consumer's choice for airlines. Due to the competition in airline industries, most of airlines offer a various level of benefits to customers such as a frequent traveller bonus, a schedule, services in flight including a meal and an entertainment program, a discounted fare and an intangible part of personal service. However, it is very difficult to measure the performance of the customers' benefit and to identify the weight of each factor being considered on the airline choice. In this paper, we focus on the airline choice process for the business travellers. The AHP is applied to evaluate the factors reflecting the business travellers' choice for airlines. This study will be useful to build a marketing plan for the business traveller's market.
