전자정부 표준프레임워크 기반 수요예측모듈의 적용 연구

While there have been growing interests on the collection, processing, and analyses of data through open source-based softwares, few studies that provide systems implementation have been published yet. This study aims to implement the e-government standard framework based system that utilizes the previously studied ARIMA demand forecasting module programmed in R, linked to the public e-procurement service database with a JAVA-based interface. Whole processes have been implemented using open source softwares along with the guidelines on user interface design for the reduced development cost and the more suitable demand forecasting application. This study is expected to be of great help for not only public sector but private ones to implement the e-government standard framework based system without any difficulty.
