The time-space conflicts may have severe negative impacts on the productivity and safety level in a construction site. However, little attention is paid to propose an automated, integrated system for managing potential time-space conflicts, considering the site space system's dynamic nature. This study contributes to the body of knowledge by proposing a novel integrated approach to manage time-space conflicts automatically. The proposed hybrid approach is based on Discrete Event Simulation (DES), Building Information Modeling (BIM), and Rapidly-exploring Random Tree (RRT) path planning. All types of time-space conflicts during the entire project timeline are automatically detected, evaluated, and resolved based on predefined if-then rules. The proposed approach is applied successfully in a real case study to estimate the project duration considering site space limitations. The results indicate that the proposed system can considerably prevent the negative impacts of time-space conflicts, particularly in congested construction sites.

用于建筑项目中自动化时空冲突管理的基于 BIM 的集成模拟

时空冲突可能对施工现场的生产力和安全水平产生严重的负面影响。然而,考虑到站点空间系统的动态特性,很少有人关注提出用于管理潜在时空冲突的自动化集成系统。这项研究通过提出一种新颖的综合方法来自动管理时空冲突,从而为知识体系做出贡献。所提出的混合方法基于离散事件模拟 (DES)、建筑信息模型 (BIM) 和快速探索随机树 (RRT) 路径规划。整个项目时间线中所有类型的时空冲突都会根据预定义的 if-then 规则自动检测、评估和解决。所提出的方法已成功应用于实际案例研究中,以在考虑场地空间限制的情况下估算项目持续时间。结果表明,所提出的系统可以大大防止时空冲突的负面影响,特别是在拥挤的建筑工地。
