Simulation Evaluation for Efficient Inventory Management Based on Demand Forecast

The AA manufacturing factory is a form of mass-producing and selling products in order to respond to customer’s needs. This means an excessive amount of material supply and demand for companies to reduce losses associated with short inventory. This results in products that fail to respond to demand accumulating in managed warehouses, resulting in higher inventory maintenance costs. In this paper, as a measure to reduce costs and inventory shortage to complement these problems, we propose a plan that predicts future demand. In order to solve the problem, ARIMA model, which is a time series analysis technique, is used to predict demand in the temporal variability or seasonal factor, and to develop a demand-forecasting model based on the EOQ model. We also ran simulation to evaluate the effectiveness of the model, and in future research, we will apply it to small and medium enterprises, to demonstrate the effectiveness of the model.
