【摘要】：随着我国城市化进程的加快,国内各主要城市的交通压力日渐增加,城市轨道交通已逐渐成为市民出行的主要工具。近年来,随着我国轨道交通建设项目投资规模的增大和建设步伐的加快,地铁车辆采购项目的时间管理也日益凸显出其重要性。本文首先分析现有的基于网络技术的CPM/PERT项目进度管理方法,以及该方法的优点以及局限性。在此基础上进一步介绍了基于约束理论的关键链法并通过实例说明关键链法的实施步骤。此外,深入分析了不同类型缓冲区的设置方法,为具体的实践提供了相应的理论支持。其次,本文进一步阐述城市轨道交通车辆采购项目的特点及其生命周期。在此基础上,结合约束理论和关键链管理提出具有适用性的轨道交通车辆采购项目时间管理的方案。对目前此类项目中存在的问题,诸如：时间估计、关键活动识别、资源平衡、过程监控等,探讨了具有可行性的解决方案。最后,本文将关键链管理运用在上海地铁L线建设中车辆采购项目时间管理的实践中,并运用仿真模拟模型验证了关键链管理在城市轨道交通车辆采购项目时间管理中的有效性。
[Abstract]:With the acceleration of urbanization in China, the traffic pressure of major cities in China is increasing day by day, and urban rail transit has gradually become the main tool for citizens to travel.In recent years, with the increase of investment scale of rail transit construction project and the acceleration of construction pace, the time management of subway vehicle procurement project has become increasingly important.This paper first analyzes the existing CPM/PERT project schedule management method based on network technology and its advantages and limitations.On this basis, the key chain method based on the constraint theory is further introduced, and the implementation steps of the key chain method are illustrated by an example.In addition, the methods of setting different types of buffers are analyzed in depth, which provides corresponding theoretical support for specific practice.Secondly, this paper further expounds the characteristics and life cycle of urban rail transit vehicle purchase project.On this basis, combined with constraint theory and key chain management, a suitable project of time management of rail transit vehicle procurement project is proposed.This paper discusses the feasible solutions to the problems existing in this kind of projects, such as time estimation, key activity identification, resource balance, process monitoring and so on.Finally, this paper applies the key chain management to the practice of vehicle purchasing project time management in the construction of Shanghai Metro L Line.The effectiveness of key chain management in the time management of urban rail transit vehicle procurement project is verified by using the simulation model.
