The results showed that the Exponential Smoothing Method with α = 0.2 had the smallest error rate, with a MAPE value of 23%, MAD of 411, and MSE of 293303. This method can be used to optimize demand forecasting for the next period, ensuring that the company has sufficient raw materials for black tin smelting. \u0000Highlight : \u0000 \u0000Accurate demand forecasting is crucial for companies engaged in smelting to prevent shortages and inventory increases. \u0000Three methods were used to determine the most appropriate forecasting method for raw material demand based on historical data: moving average with n = 3 and n = 5, and exponential smoothing with α = 0.2. \u0000The Exponential Smoothing Method with α = 0.2 had the smallest error rate, with a MAPE value of 23%, MAD of 411, and MSE of 293303, and can be used to optimize demand forecasting for the next period. \u0000 \u0000Keywords: demand forecasting, smelting, raw materials, historical data, moving average, exponential smoothing.","PeriodicalId":491073,"journal":{"name":"Procedia of Engineering and Life Science","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140443990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overloading occurs when an electric motor is used with a load exceeding its normal capacity, which can cause damage and increase the risk of fire. To overcome this problem, maintenance is needed which aims to implement and maintain the electric motor protection system. This method includes theoretical and practical sessions, where knowledge will be provided about basic protection concepts, protection system components, as well as how to organize and apply protection to electric motors. By following these directions you can improve your in- depth understanding of electric motor protection, develop skills in implementing protection systems, and gain the necessary maintenance capabilities. Positive impacts of this industrial internship include the ability to identify overload risks and implement appropriate protection systems. This not only helps optimize energy use, but also increases the company's operational efficiency and reduces damage and production disruptions.
