Demand Forecasting & Inventory Optimization
This application area focuses on predicting future product demand at granular levels (SKU, store, channel, and time) and translating those forecasts into optimal inventory decisions across the retail network. It combines statistical and machine learning–based demand forecasting with prescriptive optimization to determine how much to buy, where to place it, and when to replenish, considering constraints like lead times, service levels, and storage capacity. It matters because inaccurate demand signals lead directly to stockouts, excess inventory, markdowns, and bloated working capital. By using AI to learn from historical sales, seasonality, promotions, external factors, and real‑time signals, retailers can materially improve forecast accuracy and align inventory with true demand. This reduces lost sales and markdowns, improves on-shelf availability and customer experience, and frees up cash tied in inventory, creating a significant and measurable financial impact across the retail value chain.
The Problem
“Predict SKU-store demand and optimize replenishment under real retail constraints”
Organizations face these key challenges:
Chronic stockouts on fast movers despite high total inventory
Excess safety stock and elevated markdowns from over-forecasting
Promotion/seasonal spikes missed or overestimated at store level
Planners spend hours in spreadsheets reconciling forecast vs. buys vs. allocations

EY Demand Forecasting & Inventory Optimization
This is like giving a retailer a very smart crystal ball that predicts how much of every product customers will buy, and then automatically adjusts orders and inventory so shelves are full but storerooms aren’t overflowing.
Demand Forecasting, Prescriptive Inventory Management
This is like having a super-accurate weather forecast, but for customer demand and store inventory: it predicts what products you’ll sell and tells you how much to stock and where, so shelves are full when customers arrive without overfilling the warehouse.
