Abstract:  To fully utilize the project buffer as a risk absorption mechanism, this paper proposes a dynamic monitoring method that accounts for feeding path overflow. The proposed method divides the critical chain into phases based on feeding points and analyzes the impact of feeding buffer overflow on the critical chain during project execution. It determines the interference weight coefficient for the non-critical chain of each phase based on the consumption of the secondary project buffer caused by feeding buffer overflow. It then quantitatively allocates the project buffer across phases according to the proportion of critical chain duration and the network complexity at the feeding point. It establishes the staged rolling state of the buffer, and determines the phase dynamic rolling monitoring amount and the corresponding reference points. The experimental results show that the proposed method effectively uses the project buffer to absorb interference from feeding buffer overflow, reduces project duration and cost, and ensures project completion probability, thus improving buffer monitoring accuracy.
