摘要：
To improve the effectiveness of program management, program buffer monitoring method considering resource allocation flexibility was proposed. Firstly, based on the supply risk and delay risk of different resources within and outside the project set, the resource allocation flexibility risk index is determined. Secondly, based on the determined single item buffer and item set buffer, a two-level buffer allocation scheme is determined. Finally, buffer monitoring is performed during the execution of the project set, and subsequent buffer plans are adjusted based on buffer consumption. Through Monte Carlo simulation experiments, a case is simulated. The simulation results show that the proposed method reduces the impact of uncertainty through effective buffer management, and improves the overall performance of project set duration and cost, compared to classic buffer monitoring methods. © 2024 Systems Engineering Society of China.
