摘　　要：针对项目执行过程中计划重排和成本超支问题,考虑市政项目中特殊工序对时间窗的要求,提出了一种带时间窗的项目关键链调度方法。首先,利用基于弹性系数的缓冲确定方法,求解缓冲大小;然后,设置动态缓冲监控方法,通过仿真模型对活动执行过程动态监控,输出活动预警频次与项目总成本;最后,建立时间窗约束模型,通过仿真结果的分析与成本效益的对比,最终得到满足时间窗约束的关键链调度方法。仿真结果显示,所采用的缓冲管理方法能够减少活动落在红色缓冲区的预警频次。成本效益分析显示,相较于维持原关键链,满足时间窗约束能降低项目成本。因此,所提出的带时间窗约束的项目关键链调度方法能够在保证项目按时交付的同时有效降低项目成本。Aiming at the problems of plan rearrangement and cost overrun in the process of project execution,a project critical chain scheduling method with time window was proposed considering the time window requirements of special processes in municipal projects.Firstly,a buffer determination method based on elastic coefficient was used to calculate the buffer size.Then the dynamic buffer monitoring method was set.The simulation model was used to dynamically monitor the activity execution process and output the activity warning frequency and the total project cost.Finally,the time window constraint model was established.Through the analysis of simulation results and the comparison of cost-benefit,the critical chain scheduling method satisfying the time window constraint was finally obtained.The simulation results show that the buffer management method can reduce the warning frequency of the activity falling in the red buffer and reduce the risk of activity delay.The costbenefit analysis shows that meeting the time window constraint can reduce the project cost compared with maintaining the original critical chain.Therefore,the proposed project critical chain scheduling method with time window can effectively reduce the project cost while ensuring the project delivery on time.
