Inventory Optimization Model Applying the Holt-Winters Method to Improve Stock Levels in SMEs in the Sports Retail Sector

Organizations are aware that the world of sports retail is shaped by situations and variables that make it a complex and competitive scenario in nature. This leads to a very common problem of inventory management, because the stock levels are not suitable for market behavior, generating significant loss of sale and increase in cost and reducing margins of companies. This research seeks to design an inventory optimization model that integrates tools such as multi-criteria ABC analysis, Holt-Winters, and 5S methodology for improving stock levels in SMEs within the sports retail sector. The proposed model helps find an efficient method for the optimization sought, which enables the planning of sales and stock purchases according to the needs of the company. The main result of the validation in the case study was the reduction of additional costs by 85%.
