ABSTRACT
The notion of successive events involves such situations in which the strong dependence must be considered. On the contrary with a sequence of various traffic accidents in time, equipment failure or nonconforming product release, which occur independently in time, this kind of events comes collective, due to some common cause. Disasters in oil production or transportation, attacks of IT systems, wildfire spreading, epidemic progression are just to name a few of such examples. During the progression of successive events, a branching may occurs. The progress will be divided into several branches, each of which represents a stand-alone process of spreading.
