Accurately forecasting demand has been one of the top priorities among many businesses. While overestimating demand leads to higher inventory and related costs, underestimating demand prevents many patrons from receiving products in time. In this regard, forecasting accuracy is one of the important process that determines competitiveness of companies. However, previous forecasting models that companies use are so rudimentary that the models produce large forecasting errors. To overcome the weak point of the simple models and contribute to literature on planning and sales, this paper develops a hierarchical model of forecasting the demand of consumer products. Specifically, the proposed models incorporates the hierarchical structure of consumer product data to improve the forecasting accuracy. In doing so, this study reviews the existing studies on identify factors that intensifies forecasting inaccuracy and studies that adopted hierarchical approach method. Then we suggest a forecasting model considering the data with hierarchical features and structure. The effectiveness of the model is validated using MAPE and MAD. The results show that the proposed model outperform the existing models in the consumer products company by improving forecasting accuracy.
