We address the power generation mix problem that considers not only nuclear and fossil fuels such as oil, coal and LNG but also renewable energy technologies. Unlike nuclear or other generation technologies, the expansion plan of renewable energy is highly uncertain because of its dependency on the government policy and uncertainty associated with technology improvements. To address this issue, we conduct a delphi survey and forecast the capacity of renewable energy. We further propose a stochastic mixed integer programming model that determines an optimal capacity expansion and the amount of power generation using each generation technology. Using the proposed model, we test eight generation mix scenarios and particularly evaluate how much the expansion of renewable energy contributes to the total costs for power generation in Korea. The evaluation results show that the use of renewable energy incurs additional costs.

Since its beginning the military has continued updating its equipments and facilities by modernizing and expanding them. However, with rapidly growing technologies and business management skills, the time for military facilities' evolvement seems unavoidable. The Defense Installations Agency (DIA) has come to a conclusion that application of BIM is necessary. Since its decision, the DIA has been researching the use of BIM and developing guidelines for its application. Nevertheless, the speed of instructions and practical implementation of its model have been behind its plan due to various reasons. To overcome its limitations, the DIA has come up with three-step-solution: basic experience, budgeting, and expansion. Due to numerous number of projects of BIM, it is almost impractical to implement all of them concurrently. The methodological approach of the research employs the Delphi survey method to quantitatively analyze qualitative information drawn from experts' opinions. By applying the Delphi survey method, the first round of the survey drew lists of constraints, BIM application scenarios as well as BIM promotion measures. Afterwards, at the second round of the survey, criticality of each item collected at the 1st round was analyzed to reach a conclusion. Finally, constraints against BIM application were analyzed, and BIM application scenarios and promotion measures for the BIM were introduced.
