【摘要】：在地铁工程项目管理领域中,项目进度管理是其中的一个十分重要的分支,它是地铁项目管理中一个重要的衡量指标。在传统的地铁项目进度管理模式中,往往存在一些人为因素,比如学生综合症、帕金森定律等。这就会使得预估的工期时间延长,从而引起项目延误的状况。关键链管理技术就能使得这一状况得到很大的改善,有效弥补了传统地铁项目进度管理方法中的一些问题,所以我们有必要对关键链技术进行深入的研究探讨,这对地铁工程项目管理具有十分重要的意义。本文主要通过文献分析法等诸多方法展开探讨。首先,回顾了传统项目进度管理理论和方法,并对其中存在的问题作了简要的梳理,进而引出了关键链技术及其理论。其次,对关键链的基本理论和思想以及其基本内容和如何运用等进行了阐述,对比分析了关键链技术和传统项目进度管理方法的区别以及其优势。再次,论文对关键链的识别、缓冲区的设置与管理等问题进行了论述和分析,构建了基于关键链的地铁工程项目进度管理优化模型。此模型在汇入缓冲区的设置上对地铁工程的复杂性以及资源约束性等因素进行了综合考虑,并提出了主成分分析法,将其用于缓冲量的分配,在非关键工作后设置汇入缓冲区,这有利于项目的进度控制,从而导致关键链断裂等问题得到了有效的解决,汇入缓冲设置得到极大的改善,使其变得更加科学。最终,论文通过对A地铁工程案例进行介绍,计划各自采用项目传统进度管理方法和关键链技术制定项目进度管理计划,并深入分析比较了两者结果。通过实例分析,从而验证本文所提出的设置汇入缓冲区的方法在稳定性和可行性上都更好,而且关键链进度管理模型能够充分确保整个项目的进度管理,能够在很大程度上减少工期。通过实例对比证明,关键链管项目理技术的优点:(1)一方面分析了资源冲突,另一方面还兼顾到紧前关系约束;(2)标识资源的约束和瓶颈,有利项目过程中资源的优化配置,从而降低因资源问题而引起的进度风险;(3)为了充分确保工程顺利进行而设置缓冲区。本论文的相关研究对项目知识管理体系进行了进一步完善,有助于项目管理水平的进一步提升,因此具有较强的实践意义。
[Abstract]:In the field of subway project management, project schedule management is a very important branch, it is an important measure of subway project management. In the traditional subway project schedule management mode, there are some artificial factors, such as student syndrome, Parkinson's law and so on. This will prolong the estimated duration of the project and lead to delays in the project. The key chain management technology can greatly improve this situation, effectively make up for some problems in the traditional subway project schedule management method, so it is necessary for us to study the key chain technology deeply. This is of great significance to subway project management. This article mainly through the literature analysis and so on many methods launches the discussion. Firstly, this paper reviews the traditional theory and method of project schedule management, and briefly combs the existing problems, and then leads to the key chain technology and its theory. Secondly, the basic theory and thought of the key chain, its basic content and how to use it are expounded, and the differences between the key chain technology and the traditional project schedule management methods and their advantages are compared and analyzed. Thirdly, the paper discusses and analyzes the identification of key chain, the setting and management of buffer zone, and constructs the optimization model of subway project schedule management based on key chain. In this model, the complexity and resource constraint of subway project are comprehensively considered in the setting of import buffer zone, and the principal component analysis method is put forward, which can be used to distribute buffer amount and set up buffer zone after non-critical work. This is beneficial to the progress control of the project, which leads to the effective solution of the critical chain breakage and the great improvement of the input buffer setting, which makes it more scientific. Finally, through the introduction of A subway project case, the paper plans to adopt the traditional project schedule management method and key chain technology to formulate the project schedule management plan, and analyzes and compares the results of the two methods in depth. Through the analysis of examples, it is verified that the proposed method of importing buffer is more stable and feasible, and the key chain schedule management model can fully ensure the schedule management of the whole project. Can greatly reduce the duration of the project. Through the comparison of examples, it is proved that the advantages of the key chain management technology are as follows: (1) on the one hand, the conflict of resources is analyzed, on the other hand, the constraints of tight relationship are also taken into account; (2) the constraints and bottlenecks of resources are identified, which is beneficial to the optimal allocation of resources in the process of the project. In order to reduce the risk of progress caused by resource problems, (3) to ensure the smooth progress of the project, buffer zones are set up. The related research in this paper has further improved the project knowledge management system, which is helpful to the further improvement of the project management level, so it has strong practical significance.
