  • Smart grid, which is a sort of convergence of numerous technologies, can be deployed only with cooperation and fair competition among various stakeholders. If the interest conflicts were not coordinated properly, related business and investment would become delayed and inactive. Therefore, this study analyzes the causes of interest conflicts and related issues in smart grid sector and suggests policy directions by issue. As the result of AHP analysis, the majority of respondents surveyed said that ambiguity of the role and authority is the key problem causing conflicts of interest in smart grid deployment process. Differences in values, communications problems, etc. are pointed as additional main reasons of the interest conflicts. To resolve interest conflicts in smart grids, the Korean government should enhance its leadership in the coordination of stakeholders' interests. Government should make efforts to coordinate the various interests in terms of the development of the smart grid market and win stakeholders' sympathy of their desirable roles in the smart grid market.

  • The government continues to make efforts to improve effectiveness, integration and connectivity of public transportation systems. But there have been only a few studies about it. This paper addresses the quality evaluation of pedestrian facility service in transfer stations at urban railroad. LOS (Level Of Service) model of urban railroad by facility based on the body ellipse and density recalculated considering the recent Korean body standard and the suggested Pedestrian Moving Equivalent (PME) and Pedestrian Waiting Equivalent (PWE). For LOS model for the ticket booths and ticket vending machines, queuing theory has been applied to determine LOS of Pedestrians. And the importance weights among the pedestrian facilities is obtained by applying AHP analysis. Lastly, this paper shows and discusses the evaluation results of overall LOS of pedestrian facilities of five urban railroad transfer stations in Seoul.

  • The purpose of this study was to classify VR programs according to their characteristics and associations by the disaster management phase and firefighting school curriculum, and set priorities among VR fire training and training programs using AHP analysis., The relative priority is given considering its importance and urgency. As a result of the study, firefighting education and training classes showed the highest level of response. The relative priority of the subcategories was highest in the prevention stage. The simulation implementation for the evacuation experience was highest in closed spaces, such as a subway, and the simulation for the special firefighting vehicle was highest in the contrast phase. In the response phase, real fire simulation training was the highest. In the recovery phase, virtual reality training was the most effective in determining the fire situation based on the fire database.

  • This paper presents a new behavior planning scheme for autonomous robots, allowing them to handle various objects used in our daily lives. The key idea underlying the proposed scheme is to use affordance concepts that provide a robot with action possibilities triggered by a relation between the robot and objects around it. Specifically, the robot attempts to find the affordances and to determine the most adequate action among them. Through a series of the perception processes, robot motions can be planned and performed to complete assigned tasks. What is of particular importance from the practical point of view is a decision making capability to determine the best choice by comparing the human's body characteristics and behavioral patterns as criteria with action possibilities as alternatives. For this, the analytic hierarchy process (AHP) technique is employed to systematically evaluate the correlation between the criteria and the alternatives. Moreover, the alternatives arranged in order of priority through the decision making process enable the robot to have redundant solutions for the assigned task, resulting in flexible motion generation. The effectiveness and validity of the proposed scheme are verified by performing extensive simulations using objects of our daily use.

  • In this study, the evaluation index was developed to design the project evaluation model, and the weight was given through the AHP survey. project was evaluated for the first time by using the designed evaluation model for the field appraisal. As a result, it was revealed that the weight of the propriety index of the participant effect and the project content was the highest among 20 indexes. This study is significant in having built a base on which the evaluation system could be stabilized, by developing the integrative project evaluation model of . However, we have yet to adequately address the evaluator's acceptability and efficacy in evaluating indicators. The validity and continuity of the evaluation model will be secured through this.

  • This study was carried out to evaluate the forest sustainability index of metropolitan and provincial districts in Korea. The forest sustain ability was assessed on the bases of economic, social, environmental axes (phase), which are essential for sustainable development, and establishment. Score of importance for each phase was analyzed by the pairwise comparison of analytic hierachy process (AHP). The forest sustainability indices were measured by 15 indicators of each 3 indicators in economic, social and environmental aspects and 6 indicators in the establishment of infrastructure. The extra weight values of indicators were assigned by the value sum weight method. The forest sustainability indices were assessed for each phase, forest management and health, and integrated index, based on the data from 1995 to 2004. The forest sustain ability indices showed the highest score of 71.8 in Gyeongsangbuk-do and the lowest score of 22.9 in Incheon as of 2004.

  • This study corresponds to an exploratory survey that identifies and organizes important decision factors for establishing R&D strategic portfolio in the application of digitalized Korean human-dataset. In the case of countries that have performed the above, the digitalized human-dataset and its visualization application development research are regarded as strategic R&D projects selected and supervised in national level. To achieve the goal of this study, we organize a professional group that reviews articles, suggests research topics, considers alternatives and answers questionnaires. With this study, we draw and refine the detailed factors; these are reflected during a strategic planning phase that includes R&D vision setting, SWOT analysis and strategy development, research area and project selection. In addition to this contribution for supporting the strategic planning, the study also shows the detailed research area's definition/scope and their priorities in terms of importance and urgency. This addition will act as a guideline for investigating further research and as a framework for assessing the current status of research investment.

  • The supplier selection has a direct effect on the organization's efficiency, effectiveness and competitiveness, so the right supplier selection is the most important decision of a company. In order to select the best suppliers, both qualitative and quantitative factors should be considered. To decide which suppliers are the best and how much should be purchased from each selected supplier, many models which considered a single objective and multiple objectives have been proposed. But they have problems in considering qualitative factors which are very important in supplier selection. So in this article an integration model of an analytical hierarchy process and linear programming is proposed to consider both qualitative and quantitative factors in choosing the best suppliers and placing the optimum order quantities among them. This integrated model can be applied effectively and easily any organization and management circumstances.

  • In this study, the Hazard-based model to decide regional oil recovery capacity by using AHP is suggested and regional oil recovery capacity is calculated by applying the model. The simulation for oil recovery capacity by mobilization of regional oil recovery equipments is carried out to verify the availability of the model. The worst oil spill accident in Daesan Taean Pyeongtaek region, which is located in geographically disadvantageous position among the regions that the worst oil spill accident may occur, is supposed for the simulation. As a result of simulation, the quantity of oil that can be recovered for three days on the scene of oil spill accident is worked out as $15,841k{\ell}$, which can satisfy the goal of national oil recovery capacity for the worst oil spill accident, therefore the model is verified as practicable.
