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.

There are many positioning studies utilizing Analytic Hierarchy Process (AHP) in tourism industry. In this study, it was tried to develop new evaluation criteria for positioning and to discuss the importance of evaluation factors, as the development of tourist's spots was pursued in diversified ways. The purpose of this study was to allow the development of tourist spots more objectively and more efficiently utilizing Analytic Hierarchy Process ("AHP" hereunder) to appoint the best place for the tourism complex in Buyeo. According to AHP analysis procedures, 5 places near Baikje Cultural Block connecting with a ferry in Buyeo-gun were selected as candidates. To perform AHP analysis, evaluation criteria and a survey were used and then weight of evaluation criteria was induced. With the conditions on criteria, standard score of each criterion and candidate was calculated. By multiplying standard score and final weight and then summing up, the candidate place with the highest score shall be appointed as the most optimal place for Buyeo-gun Agricultural Tourism Complex.

Railway line segment deterioration can be affected by rail tracks, subgrades, bridges, tunnels, and line shapes. In this paper, an evaluation method is presented for the railway line segment deterioration using the analytic hierarchy process (AHP) and data envelopment analysis (DEA). The importance weights can be assessed systematically for component facilities from numerous experts using AHP. The importance weights provided by experts may differ according to each expert; however, the DEA enables the evaluation of railway line segment deterioration that reflects the variety of expert opinions using these importance weights.

In this paper, we propose a data envelopment analysis (DEA) and analytic hierarchy process (AHP) integrated model to improve the selection process in the acquisition of a weapon system which is the key component to the success of the project. In particular, we applied DEA in the first stage to choose a frontier group among the candidates in the selection process of the next-generation fighter system (the 3rd FX) in Korea. Then, by using the Delphi technique, we surveyed military experts and applied AHP to determine the best choice among the candidates. The results of the study match the actual decision made by the Korean government in the weapon system acquisition. The results of the proposed DEA-AHP integrated method in the selection of the next-generation fighter systems in Korea demonstrate the usefulness of the method. In this paper, we also discuss the future implications of the proposed model.

This study proposed a Rural Amenity Values Assessment Model (RAVAM) to evaluate the rural amenity resources based on the Myun as a spatial unit. In RAVAM, 61 rural amenity resources were classified into almost intact nature resources, interaction between nature and man resources, man-made resources, respectively. Especially, Rural Scenic Value Index (RSVI) was developed to quantify rural scenic views as a rural amenity resource. RSVI was utilized in evaluation process of rural amenity resources. The weighing factors for the amenity resources were evaluated from the step wise pair-comparison results of 11 specialists by Analytic Hierarchy Process(AHP). In the results, the weighting values of almost intact nature resources, interaction between nature and man resources, man-made resources were 496, 323 and 181, respectively, among total value being 1,000.

The feasibility evaluation of public projects has been carried out mainly in the economic analysis. However, items of political, technological and balanced regional development aspects are further evaluated by applying analytic hierarchy process, This paper suggests to analyzes preliminary feasibility study of construction and research & development project during the past three years and to verify correlation between B/C ratio and AHP weight. The result shows that the correlation between cost benefit ratio and the weight of the hierarchy is 0.744 in construction projects and 0.899 in research & development project. Namely, AHP weight be under the control of B/C ratio and is devoted to its role against expectation. Therefore it must be sufficiently discussed in various designs of studies to maximize the effects of AHP analysis.

Mobile game users tend to value the opinions from their friends or SNS when making a decision on which game to play. This is because they are not satisfied with the information on suggestions provided by the conventional mobile game recommendation systems. In this research, we made a system that can reflect user preference directly by using Analytic Hierarchy Process(AHP). In the system, the hierarchy of AHP is composed of final goal(Level 1), evaluation basis(Level 2) and alternative(Level 3). And the system is made up of an input module, an AHP processing module, a recommendation module and database. Through comparison analysis with two conventional systems to test the performance of the system, we could find that the system got more higher satisfaction than the other systems.

In this study, the evaluation criteria of performance and applicability is developed to rank the combinatorial technologies for SWG (Smart Water Grid) system using AHP (Analytic Hierarchy Process) method. Security, safety, solution, suitability and sustainability which are goals of SWG technology, are used as upper level hierarchy elements. And three detailed elements for each upper level hierarchy are adopted as the lower level hierarchy. The weighted value which represents the importance of each element, could be determined through questionnaires accomplished by groups of specialists who are engaged in relevant waster industry and research area. To assess the accuracy of the evaluation criteria developed in this study, a simulation on four decision alternatives for smart water grid was carried out as an evaluation. Consequently which showed 90 % of accuracy.

Recently, habitat fragmentation and shrinkage has occurred because of increased road construction. As a measures mitigating the adverse effect such as eco-island by road construction, Korea has been installed eco-corridors since 1995. Using the Analytic Hierarchy Process (AHP), this study analyzed the importance of assessment items and the criteria to determine which areas require eco-corridors the most. First, related literature reviews, preliminary surveys, and expert interviews were carried out to develop assessment items and criteria for constructing the hierarchy. Second, experts were surveyed in order to determine the relative importance of the assessment items by applying the AHP. As a result, it found that the restoration of the ecological network was the most important assessment item, followed by wild animal resources in the Level 3. In the Level 4, the eighteen items were ranked in the order of their relative weight and it was found that the 'Baekdudaegan Mountain Range (0.189)' was the highest ranked item. Therefore, this approach can be applied to effective selection of the priority areas in planning eco-corridors in the national scale.

An optimal selection problem of SCM system is one of the critical issues for the company's competitiveness and performance under global economy. This paper presents a hierarchy model consisted of characteristic factors for introducing SCM system and an AHP (Analytic Hierarchy Process) based decision-making model for SCM system evaluation and selection. The proposed model can systematically construct the objectives of SCM system selection to meet the business goals. This paper focuses on selecting an optimal SCM system considering both all decision factors and sub-decision factors of a hierarchy model. Especially, the benefit/cost analysis is applied to choose SCM system. A case study shows the feasibility of the proposed model and the model can help a company to make better decision-making in the SCM system selection problem.
