施工设备维修对工程进度影响的SD 模型及应用 ——以中亚某天然气管线建设工程为例

在现代建设工程中，施工设备维修对建设工程进度的影响日益增大，另一方面，工程实践中常见的赶工现象又可能导致设备超负荷运转，增加了维修管理的难度。系统动力学及相关软件为理顺施工设备维修与工程进度之间的关系、估计施工设备需求量提供了有效的工具。通过建立施工设备维修—工程进度联动模型，并使用该模型对某天然气管线建设工程进行模拟，发现在考虑施工设备维修的情况下，采用仿真方法，可以对多种方案进行有效的评估。

System Dynamics Based on Simulation of the Relationship between Equipment Maintenance and Construction Progress: ----A Case of the Central Asian Natural Gas Pipeline Project

In modern construction projects，influence of equipment maintenance on the construction progress is increasingly significant. On the other hand，speeding construction often results in equipment overloaded. It increases difficulty of equipment maintenance management. To coordinate the relationship between the two and to determine the original number of equipments， system dynamics (SD) provides an effective tool. By establishment of the linkage model of equipment maintenance and construction progress, a gas pipeline construction project is simulated. It is discovered that when considering equipment maintenance，the SD method would provide an effective assessment to different plans.
