ChatGPT plugin

Demand planning & forecasting

View in ChatGPT directory

The SupChains Way is the method SupChains applies on every demand planning and inventory planning project. It holds 13 practices and the 16 articles behind them, written by Nicolas Vandeput. Nicolas is the author of Demand Forecasting Best Practices, Data Science for Supply Chain Forecasting and Inventory Optimization: Models and Simulations. He also organized VN1 and VN2, two open forecasting and inventory competitions on real retail data.

Ask about forecast accuracy and KPIs, MAPE, bias, Forecast Value Added (FVA), machine learning forecasting, forecast changes by planners, S&OP, working with sales and finance, ABC/XYZ segmentation, outliers, safety stock, service levels and inventory simulation.

Every answer takes a clear position, gives the reason, and links the source article on supchains.com.

Your questions stay in ChatGPT: SupChains receives nothing.
