The Unified Modeling Language (UML) is a conceptual language which is nowadays widely used to describe and model complex processes. At the origin, UML is focused on structural and behavioural modeling rather than on temporal one, whereas time notion is omnipresent in real-world processes. Hence, in this paper, we propose to introduce new temporal notations complementing standard UML activity diagrams notations in order to model the time aspect of processes in terms of temporal interval concepts. Experiments within real-world scenario have demonstrated the usefulness and efficiency of our developed approach.
