Perencanaan Jumlah Produksi Mie Instan dengan Penegasan (Defuzzifikasi) Centroid Fuzzy Mamdani (Studi Kasus : Jumlah Produksi Indomie di PT Indofood CBP Sukses Makmur Tbk Tanjung Morawa)

Abstract

The problems that arise in industry often have no definitive answer. Fuzzy logic is a method to analyze the uncertain system. This study discusses the application of fuzzy logic in solving problems with the production of Mamdani approach. The existence of inventory / stock goods in warehouses that will most likely result in damage to both the content and packaging, as well as items that can cause harm expired PT. Indofood CBP Sukses Makmur Tbk. To obtain maximum benefit, the company must do to meet the maximum sales with the market demand and the amount of the corresponding right. Therefore, it takes planning production quantities of goods at a specified time in order to meet the market demand and the amount of the corresponding right and minimize losses due to incompatibility with the sale of goods produced (excess inventory / stock items). In this study completed with the help of Matlab software and the obtained optimal production quantities when compared with the results of calculation of the value of the MPE (Mean Percentage Error) and MAPE (Mean Absolute Percentage Error) of the amount of actual production with forecast production quantities of Mamdani Fuzzy is not much different from the calculation MPE (Mean Percentage Error) and MAPE (Mean Absolute Percentage Error) of the amount of actual production with forecast production quantities of Forecasting Company.
