  • World have been encouraged to develop technologies that contribute to CO$_2$ emission reduction for many years. Those technologies can be categorized into capture, storage or sequestration, utilization, etc. There have been lots of efforts, in Korea, to develop the technology as well. In this paper, the impact factors of the technologies, especially in CDRS (Carbon Dioxide Reduction & Sequestration Center), were selected and were weighed by SMM (Storing Models Method) and AHP (Analytic Hierarchy Process) in order to evaluate the four representative areas of the technologies.

  • This study suggests the organization-level standard(model and process) for quality evaluation of information systems(IS) in non-use organizations despite international standards(ISO/IEC 9126 and ISO/IEC 14598) and national standards(KS X 9126 and KS X 14598) related to quality evaluation of IS. The standard in this study is composed of quality evaluation processes, a quality model, and quality metrics. The weights of the attributes and the sub-attributes in the quality model were calculated by an analytic hierarchy process(AHP). The minimum level and the target level of each metrics were determined by brainstorming of the committee. Furthermore, the case study for the investigation of the applicability and the usability of the suggested organizational standard in the real IS development project was performed. For gaining significant benefits of the standard, both the diffusion and the experience accumulation by its continuous use are needed.

  • ABC analysis is the process of dividing inventory items into three classes according to their monetary usage so that managers can focus on items that have the highest monetary usage value, and has been widely used in practice since its development in 1950. However, the original criterion, monetary usage value, can no longer be the only rational criterion. Applying Analytic Hierarchy Process, we develop a new method to classify inventory items by considering such operationally/strategically important criteria as annual dollar usage, lead time, supplier's capacity, defective rate, difficulty of purchasing and unit price. A case study is performed applying the method to the field data from a company which produces electrochemical products.

  • The importance of intellectual property is increasing in the knowledge and information era. An organization that embraces technology and strategy is faced with promising opportunities and managerial difficulties. Forecasting the performance of technology and the underlying costs to achieve such performance is even more difficult than before. Those organizations that employ technology as part of their strategic arsenal know that they are running serious risks, which clearly increases the uncertainty of organizational performance. Therefore forecasting the performance of technology is a difficult task since technology has been characterized by intangible and tacit factors and traded in a supplier's market. The decision makers usually face a complex system of interrelated components, such as resources, desired outcomes or objectives. This study intends to evaluate the contribution of technology in intangible assets by the Analytic Hierarchy Process.

  • In this paper, we study the distributed cooperative caching for Internet content providers in a small cell of heterogeneous network (HetNet). A general framework based on bankruptcy game model is put forth for finding the optimal caching policy. In this framework, the small cell and different content providers are modeled as bankrupt company and players, respectively. By introducing strategic decisions into the bankruptcy game, we propose a caching value assessment algorithm based on analytic hierarchy process in the framework of bankruptcy game theory to optimize the caching strategy and increase cache hit ratio. Our analysis shows that resource utilization can be improved through cooperative sharing while considering content providers' satisfaction. When the cache value is measured by multiple factors, not just popularity, the cache hit rate for user access is also increased. Simulation results show that our approach can improve the cache hit rate while ensuring the fairness of the distribution.

  • IMO has enacted a convention that air pollution due to emissions of ships and sulfur oxides emissions should be significantly reduced by 2020. Based on the current support policies, this work intended to draw up the government support plans required by the shipping companies. Analytic Hierarchy Process analysis was done with factors derived from brainstorming and literature studies. The analysis results showed that the cost factor was generally the most important criterion and the Financial Aid was relatively more important within this cost factor. The policy implications for the regulation of sulfur oxides emissions was provided.

  • This study aims to determine the importance of each factor considered when operating a rotorcraft in a city. After identifying factors that could affect urban air mobility, we reviewed the influencing factors by applying an analytic hierarchy process (AHP). Level 1 classifies the essential factors of the urban operation of rotorcraft in nominal and off-nominal situations. The factors corresponding to the characteristics of each were composed of lower levels, such as Levels 2 and 3. Using this, the importance of influencing factors was analyzed and the most important factors were determined. The most influential factors of the urban operation of rotorcraft included engine failure, fire situations, and vehicle safety. Accordingly, an environment that can guarantee safe operation by considering the most influential factors in advance in an actual operation stage must be constructed.

  • To improve construction productivity and quality, and to make the construction environment safe, a new system, Robot-based Construction Automation (RCA), is currently being developed in Korea. To determine whether RCA is an improvement over traditional construction methods (TCMs), an evaluation method, called the Performance Evaluation Index (PEI), is suggested for RCA. The PEI considers the relationships among the factors influencing the performance of the system obtained using the Delphi method and the analytic hierarchy process (AHP). As the evaluation shows, RCA is much better than TCM except for three factors: the rate of work success, quality improvement by learning experience, and construction duration.

  • This study aims to provide basic data for establishing strategies for asset management in the future through priorities and influence of the asset management items of public facilities in Korea. To this end, 4 upper items and 20 lower items in priority were selected based on existing literature. The analytic hierarchy process was used to determine the importance of each of the selected items, and the interpretive structural modeling (ISM) technique was used to examine the relationships among the 20 lower items. On this basis, directions for the efficient asset management of public facilities were suggested.

  • The purpose of this study is to investigate and analysis importance for evaluation indicators in youth centers. The sample of it is 138 youth centers. Method of this analysis of importance for its indicators is AHP(Analytic Hierarchy Process). Evaluation domains in youth center are process evaluation, product evaluation, input evaluation and specialized program in order of importance. Also, it is important to evaluate in needs assessment, recruitment of youth instructor, participation of youth in decision making, connective project with schools, sanitation level of youth center, satisfaction research, efforts of improvement of youth center staff in evaluation indicators. The result of this study is that importance for evaluation indicators suggests developmental directivity in youth center management.
