AI-Enabled Demand Forecasting and Inventory Optimization in Retail
Walmart, the world's largest retailer, harnessed artificial intelligence to transform its demand forecasting and inventory management, driving greater efficiency and customer satisfaction. With thousands of stores and a massive e-commerce platform, Walmart faced the challenge of predicting consumer demand for millions of products daily.
Through AI algorithms analyzing historical sales, online search trends, weather, and events, Walmart significantly reduced stockouts by an estimated 30% while cutting excess inventory by 20-25%, leading to higher sales and improved customer satisfaction.
