Problem

Global expansion made it harder to supply each store with the right products at the right time.

Approach

Fast Retailing developed an AI demand-forecasting model with Google. It fed forecasts into sales plans and used algorithms to connect those plans with production and inventory planning. The company described this as daily operating practice in October 2021.

Results

No published figures

Takeaway

Forecasts fed operational planning, although Fast Retailing did not quantify their accuracy improvement.
