Making stationary retail more attractive to customers again with the help of digital solutions – this was the goal of the partners working together on the Knowledge4Retail (K4R) project from January 2020 to December 2022. The group presented the results at the final meeting this spring. The core of the project is a K4R open-source platform available on internet host GitHub, a version control system, which makes the results accessible to retailers. Retail companies can use the platform to connect analog and digital worlds as well as analyze processes more easily and generate purchasing behavior forecasts, for example. In the process, the project partners developed solutions for applications in logistics, store set-up, service robotics and a fully automated kiosk.
