【摘要】：在项目建设过程中,进度管理是项目管理三大要素之一,直接影响了项目的成本和质量,是项目管理不可或缺的一部分。在空管系统中,项目管理最常使用的是关键路径法、甘特图法,通过制定可靠的工期计划,达到对工程进度的控制,尽可能减少工程建设中的不确定因素的影响。但是制定项目计划后,经常出现本可以提前的工序并没有的到加速,不确定因素造成工序延误。这是由于工程的不确定性,以及“帕金森”定律、“学生综合症”的影响,项目团队中局部出现拖延现象,导致整个工程的拖延,项目进度难以管理。显然,传统的项目进度管理技术存在着不足。为了解决以上问题,本文依托空管大厅工程,对其进度管理模式进行分析,寻找比传统方式更加适合的项目管理技术—关键链法,关键链法的优势在于从项目的全局角度出发,调配可利用的资源,寻找关键链路,缩小项目中每个工序的工期,并为关键链路及非关键链路上的工序设定缓冲区,以提高项目按期完成的概率,提高项目效率,节约项目成本。本文综合考虑了工序、资源的情况,提出了设置缓冲区的方法,结合工程实例,分析解决了工程面临的实际工期问题,并提出了工程实际中监控项目进度的有效方法。最后,对工程的工期进行了仿真计算,验证了方法的适用性。本文的研究将理论与空管工程建设结合,为其他项目的工期管理提供了借鉴,具有理论和现实意义。
[Abstract]:In the process of project construction, schedule management is one of the three elements of project management, which directly affects the cost and quality of the project and is an indispensable part of project management. In the air traffic control system, the key path method and Gantu method are used most frequently in the project management. By making a reliable schedule plan, the project schedule can be controlled and the influence of uncertain factors in the project construction can be minimized as much as possible. But after making the project plan, it often appears that the process which could have been advanced does not accelerate, and the uncertainty causes the process delay. This is due to the uncertainty of the project, as well as the influence of Parkinson's law and student syndrome, and the phenomenon of partial procrastination in the project team, which results in the delay of the whole project and the difficulty in managing the project progress. Obviously, the traditional project schedule management technology has the insufficiency. In order to solve the above problems, this paper, relying on the air traffic control hall project, analyzes its schedule management mode, and looks for a more suitable project management technology-the key chain method, which is more suitable than the traditional method. The advantage of the key chain method lies in the overall view of the project. Allocation of available resources, finding critical links, reducing the duration of each process in the project, and setting buffers for processes on critical and non-critical links to increase the probability of project completion on schedule and improve project efficiency. Save project cost. In this paper, the working procedure and resources are considered synthetically, and the method of setting buffer zone is put forward. Combining with the engineering example, the problem of actual project duration is analyzed and solved, and the effective method to monitor the project progress in engineering practice is put forward. Finally, the project duration is simulated and the applicability of the method is verified. The research in this paper combines the theory with the construction of ATC project, and provides reference for other projects. It has theoretical and practical significance.
