Pengendali Persediaan Barang Menggunakan Metode Single Exponential Smothing Untuk Peramalan Penjualan

CV. Usaha Muda Materials is a company engaged in the distribution of wood, cement, iron and other building materials. Frequent errors data collection purchases sales lead to disinformation goods. Prediction process for estimating how many needs future which include terms quantity, quality, time location needed order meet demand goods or services. number inventory items can be calculated using exponential smoothing, Exponential smoothing often called Smoothing, method prediction with moving average technique where weighting weighted an function. The research methodology has steps that are used solve problems arise. occur this study regarding Young Business Single Smoothing method. results obtained by finding constant value (alpha) smallest error Mean Squered Error (MSE), Root Squred (RMSE), Absolute (MAE) Percentage (MAPE) methods. Smothing have predictions 132 rods January 2022. Based on accuracy test 3.01, (MSE) 18.18, MAPE (Mean Error) 9% 0.3. So taken into consideration as evaluation appropriate decision making minimize risk losses due management business capital.
