Abstract
The work in collaboration with the company Sonae, comércio e serviços, focused on two different problems:
- Sales forecasting in retail. This problem was approached using soft computing techniques for three different forecasting periods: stationary, stationary with disturbances and non-stationary. Feature extraction was one of the key factors for this work as some of the features have a strong effect on sales and had to be extracted/designed for the problem.
- Alarm system for retail supply chains. This problem was approached using discrete event simulation modeling.
