The MPM method makes it possible to evaluate the duration of the realization of a complex project and to detect the parts of this project not supporting any delay. The information about the tasks is summarized in a schedule.
Unlike the PERT method, the vertices of the BPM method are tasks to be performed. We can “consider” that the edges of the PERT method become vertices in the MPM method (similarly for the vertices becoming edges).
Which gives the following graph:
