摘要
现有缓冲分配与监控方法不能充分利用已完工工序的剩余缓冲,导致项目的缓冲消耗偏高,从而影响项目的准时完工率。基于此,在综合考虑工序的三个重要性指标的基础上,提出了一种动态缓冲分配与监控方法。首先,构建工序重要性的指标,并运用熵权-逼近理想解排序法(technique for order preference by similarity to ideal solution,TOPSIS)确定在三个指标影响下的工序重要度系数;其次,在项目执行过程中依据工序重要度的变化构建动态分配与监控模型;最后,案例采用MATLAB仿真验证优化的结果。仿真结果表明,所提出的方法减少了项目工序的缓冲消耗,提高了后续工序对已完成工序剩余缓冲的利用,缩短了项目工期,提高了项目的完工概率,降低了项目的延误风险。
Existing buffer allocation and monitoring methods do not fully leverage the remaining buffers of completed activities,resulting in excessive buffer consumption and adversely affecting project on-time completion rates.To address this issue,a dynamic buffer allocation and monitoring method was proposed,considering three key importance indicators of activities.Firstly,activity importance indicators were established,and the entropy-weighted TOPSIS method was employed to determine the importance coefficients of activities influenced by these indicators.Secondly,during project execution,a dynamic allocation and monitoring model was developed based on the changing importance of activities.Finally,MATLAB simulations were conducted to validate the optimization results.Simulation results demonstrate that the proposed method reduces buffer consumption levels for project activities,improves the utilization of remaining buffers from completed activities,shortens project duration,increases completion probability,and decreases the risk of project delays.
