In recent years, Tesco has used MATLAB to automatically predict how promotions and British weather affect product food sales in its 2,400 UK stores. In this session, Duncan will present some of the most recent innovations from the supply chain development department. In particular, the team has improved promotional forecasting and price optimisation of the reduced to clear process. Furthermore, simulation and analysis of the supply chain has provided more accurate demand forecasts and led to improved supplier agreements. Tens of millions of pounds have been saved through these changes.
