From this problem the dealere needs a system that can provide information about motorcycle sales predictions to assist dealer in determining motorcycle inventory. This study describes the process of developing a motorcycle sales forecast information system using the Double Exponential Smoothing method and Unified Language Modeling (UML) as a system design. The outputs of this system are table and graph which exhibit motorcycle sales predictions.enMotorcyle SalesPredictionDouble Exponential SmoothingArticle
