The second on-site technical review took place at KLEEMANN Hellas S.A. and at ELDIA S.A. on March 14th, in Kilkis and Thessaloniki respectively. The end users demonstrated the use of COMPOSITION tools, as they have been implemented and installed for them. It was evident that the consortium did more than what has been described in the objectives of the project. The reviewer saw in real time the loading of the machine and at the same time the response of the Visual Analytics tool, as well as the notifications from the Decision Support System. The technology providing partners were advised to take into account requests from end users to make outcomes more useful for them and also attractive for exploitation.
