基于多因素影响下缓冲区设置的进度风险预警
Schedule Risk Early Warning Based on Buffer Setting with Multi-factor Influence
摘要
Abstract
In the process of construction progress, deviation can be made easily if engineering project schedule affected by the uncertain factors. Considering factors of the construction difficulty and the risk bias coefficient and work complexity in the process of construction, this paper put forward the modified idea of buffer setting method in the core of the critical chain method and the progress schedule of improved critical chain. On the basis of it, this paper built the fundamental model of schedule risk dynamic early warning control by taking the schedule variance rateas monitoring index. The example analysis showed that on the premise of high completion rate the improved critical chain method schedule control can effectively shorten project planned period,using the model for real-time schedule accomplishment monitoring can efficiently and accurately provide decision information of schedule management for policymaker. Combined with the prior control and afterwards control can effectively control the negative impact of uncertainty factors effected to progress.关键词
