There are more and more data sources available in the world every day. This is the opportunity for organizations to improve their situation awareness in order to take better decisions, faster than ever before. The GéNéPi project was set up to help them: it aims to support their collaboration, in real-time, whatever the complexity or instability of the environment. To set up and test the solution proposed by the project’s consortium, a crisis use case has been developed by official sources. This article shows a new approach to automating the creation and update of a situation model, in real-time to offer: (i) the decision-makers a common operational picture; (ii) the GéNéPi project a base on which a collaborative process is defined and maintained to the benefits of the decision makers.
