| 摘 要： | 重复性项目经常受到不确定性事件的干扰而遭受工期延误和费用损失，为应对这种不确定性，考虑重复性项目工作连续性要求，研究其鲁棒调度优化问题。首先，根据工作连续性要求，结合时间缓冲设计适合重复性项目特点的鲁棒优化指标并建立鲁棒优化模型，提出适合重复性项目特点的时间缓冲计算方法和分配方式，在保证进度计划解鲁棒性最大化的同时提高质鲁棒性，并以某高速公路工程为例，通过蒙特卡洛模拟分析鲁棒优化模型的效果。结果表明：鲁棒优化模型非常适合工作连续情况的重复性项目，能够在保持工序连续性的同时，在工序之间合理地添加分散缓冲和项目缓冲，从而有效提高进度计划的解鲁棒性和质鲁棒性，可以帮助重复性项目管理者构建一个适合项目特点且具有一定抗风险能力的进度计划。

Robust scheduling optimization for repetitive projects considering the work continuity of crews |
| |
| Abstract: | Repetitive projects often face various uncertainties during their execution, suffering from project delays and/or cost overruns. To address this challenge, this study considers the requirement of the work continuity and study the robust scheduling optimization problem. Firstly, the time buffer technology is applied to repetitive projects to ensure the work continuity of crews, and a new robustness measure is proposed according to the characteristics of repetitive projects. Secondly, this paper presents a robust optimization model for scheduling repetitive projects and designs the corresponding solution program. Finally, an engineering example and a Monte Carlo simulation experiment show that the proposed robust optimization model is very suitable for repetitive projects with continuous activity and can effectively improve the solution robustness and quality robustness of schedule. This paper can help repetitive project managers to construct a schedule that is suitable for their characteristics and has certain risk resistance ability. |
