It is difficult to provide proper cloud services for cloud users, because the number of cloud services are increasing and the type of cloud services are diversifying. To overcome this problem, the concept of cloud service broker is presented to mediate cloud services between cloud providers and tenant. The most important role of cloud service broker is to finding cloud services that fulfill requirements of tenant. However, current existing cloud service broker conduct passive requirements analysis process with cloud service expert's assistance. In addition, the systematic functional and non-functional requirement analysis is insufficient. Therefore, we need the new methods for requirement analysis to find nearest service that matches with requirement of tenant. In this paper, we apply pairwise comparison from AHP method to analyze requirement automatically and systematically. It calculates score of service by comparing requirement with service specification, calculating importance rate, and so on.

Association of South East Asian Nations(ASEAN) has recently decided to develop ASEAN Highway Network to connect member countries by road in an attempt to achieve a goal of closer economic integration in the region. This entailed the necessity to newly construct or upgrade some 5,481 km of road sections to make ASEAN Highway Network functional. This study offers haw we can prioritize development of these road sections using the Analytic Hierarchy Process. Particularly, it shows how individual road sections can be prioritized considering the importance of corridor or road group where the individual road section lies. It also develops how values of different evaluation criteria can be compared in the same scale. This new approach can be useful in prioritizing highway development in such cases where candidate road sections are widely scattered around the region, so detailed benefit and cost analysis is practically too demanding to carry out.

Transit Oriented Development(TOD) has been the dominant paradigm for urban development. The traditional approach to the development of urban rail station areas demonstrates apparent weaknesses when it comes to compact and mixed-use types of development for these stations. Thus, the objective of this study is to derive evaluation indicators with which to assess urban rail station areas using TOD planning elements. A focus group interview was conducted to explore TOD planning elements. In order to examine the level of TOD to be achieved, an AHP technique was utilized to analyze the importance of several variables. Z-scores and Re-scores were applied to derive the values for the stations. The Variables related to the land use type, mixed use, floor area, and public transit were found to be the major contributing factors to the achievement of TOD in urban rail station areas. The results of this study show that the level of TOD achievement varies according to the major land use, density, accessibility, and mixed-use planning elements.

The purpose of this study is to evaluate the technological competitiveness of the environmental industry with developed countries in order to establish an international market expansion strategy of the Korean environmental industry and technology. In order to evaluate the competitiveness of the environmental industry and technology, core technologies were classified by the environmental industry sectors based on the classification system of the domestic and international environmental industry and technology. After developing the evaluation index data, the Delphi analysis, journal and patent analysis, as well as the export and import analysis were carried out and the standardization analysis was performed on the index data. Moreover, the weights of each evaluation index were calculated using the AHP(Analytic Hierarchy Process) method and the evaluation results of competitiveness of the environmental industry and technology in Korea, the United States, the United Kingdom, Germany, and France were derived. As a result of the evaluation, the United States was rated with the highest technological competitiveness in all the environmental industry sectors, while Korea got the lowest technological competitiveness rating compared to the 4 developed countries. In particular, Korea got the lowest level of technological competitiveness in the sector of multi-media environmental management and development for a sustainable social system. Therefore, in order for the Korean environmental industry and technology to enter the global advanced market, it is necessary to strengthen the competitiveness through the development of the fourth environmental industry based on IoT(Internet of Things), cloud, big data, mobile, and AI(Artificial Intelligence), which are currently the country's domestic strengths.

During the development process of mega-project, individual buildings including skyscrapers are built following the master plan. It is not a difficult thing to see the gap of standpoint between the urban planners and architects on the project. This study aims to analyze the difference between architect and urban planner's point of view in evaluating international design competition works which the internationally distinguished honorable design companies(SOM, Jerde Partnership, Studio Daniel Libeskind, Foster+Partners and Asymptote Architecture) submitted as the ideas of Yongsan International Business District Design. Furthermore, we made an attempt to quantify the weight of each factors of urban design by each group. Architect and urban planner's viewpoint were revealed with seven architects and seven urban planners evaluating the international design competition works through AHP(Analytical Hierarchy Process). AHP structure was made of two step hierarchy in terms of Master Plan and Landmark Tower. Eight evaluation criteria were set up such as the concept, land use, transportation, feasibility of Master Plan and the concept, location, functional efficiency and aesthetic beauty of Landmark Tower. Results show that Architect have different point of view from that of urban planner. While the architect's weight of evaluation criteria is on the Landmark Tower(0.505), urban planner's weight is on Master Plan(0.642). Feasibility, the location of Landmark Tower and land-use are very important evaluation criteria to architect and urban planner in common. Functional efficiency of Landmark Tower is in architect's favour and transportation is in urban planner.
