铁路建设工程进度计划优化模型研究

为了解决铁路建设工程资源不均衡的问题，避免出现劳动力窝工或机械设备闲置的现象，本文以资源均衡为目标，以线性规划方法确定建设工程中的关键路线，构建了适合于我国铁路建设工程的进度计划优化模型，并进行了施工速度差的求解.采用朔黄铁路建设工程的实际数据，对该模型的有效性进行了验证.结果表明，该模型大大降低了实际施工进度计划的资源计划偏差值和资源占用的峰值.因此，该模型对于解决我国铁路建设工程中的资源不均衡问题具有显著效果，对于提高我国铁路建设工程进度计划的科学合理性具有较好的理论和实际应用价值.

Optimization Model of Railway Construction Project Schedule

In order to solve railway construction project resource imbalance problem and avoid labor slowdown or mechanical equipment idle occurrence, this paper aims at the resource leveling. The linear scheduling method is used to determine the critical path in a construction project. The optimized model of progress schedule suitable for Chinese railway construction project is built, and the difference of construction speed is solved. Using the actual data of ShuoHuang railway construction engineering, the validity of the model is verified. The results show that this model greatly reduces resource planning deviations value and the peak occupied resource value of actual construction schedule. Thus, this model has obviously effects on solving resource imbalance problem in Chinese railway construction project and has important theoretical and practical application values for improving scientific rationality of schedule in Chinese railway construction project.
