In recent years, the digitalisation process has created a huge amount of data at Brussels Airport. The challenge is to handle all this data intelligently and to use it to improve the experience of both passengers and employees. That is how the Airport Operation Plan (AOP) came about: this plan gives airport employees clever insights into the various airport flows which enables them to take proactive action to prevent problems. The plan was translated into a web application that visualises the data and makes it more easily accessible to employees. The system we use to collect and convert data into predictions for the future is called the predictive module.
