Sistem Prediksi Jumlah Produksi Baju Menggunakan Weighted Moving Average

Currently, technological advances for information processing are growing very rapidly. This technology has been used in various fields everyday life. By using this technology, it is hoped that the work will be faster and more efficient. Due to being able manage quickly efficiently, possible every company its process use one of which production process. The making or providing value an item. important processes because if there a shortage excess amount affect sales. Therefore, predictions needed estimate number products produced so no production. In study, prediction system made where data taken from Ummajee Store clothing store clothes sold results their own method determine Weighted Moving Average method, different weighting technique each given data. study calculate error predicting mean absolute percentage (MAPE), while analysis functional requirements uses Unified Modeling Language (UML). research, running as get 21% with can predict production, well accordance testing user response 92% means states properly assist decisions next period.
