【摘要】：项目进度管理是项目管理中最重要组成部分。项目进度管理就是要保证项目在规定的质量、成本、时间内完成整个项目范围。项目进度的计划和控制是项目进度管理的核心。目前常用于电力工程的进度管理方法有关键路径法、计划评审技术和挣值法等。这些方法在实际运用中能消除项目的不确定性因素影响,对项目进度起到有效的管理作用,但是这些方法在不断地运用中也发现了自身的一些缺陷,比如没有考虑资源的限制；只专注于每个工序的管理,强调每个工序的按期完成,而没有从项目整体考虑；工期计划过长、项目安全时间白白消耗等问题。本文首先对关键链进度管理的国内外研究现状进行分析研究。然后进一步分析了目前智能变电站建设项目进度管理的现状,针对现有的项目计划工期过长、安全时间浪费、资源约束考虑不足和进度难以控制等问题,提出利用关键链进度管理方法来对此类项目的进度管理进行优化。接下去,本文在对关键链相关理论进行研究的基础上,将关键链理论方法应用到智能变电站项目进度管理中,提出了关键链项目进度管理模型,具体设置了关键链进度计划模块和关键链进度控制模块。本文在项目工期和缓冲区计算中,针对智能变电站项目的特点,利用德尔菲法对项目工期大小进行计算,利用根方差法对缓冲区大小进行计算,这两种方法简单易用。然后,本文将缓冲区作为项目进度计划和控制的桥梁,在项目进度控制中,通过在缓冲区设置三个预警区间,结合项目组织分层管理方法,分级管理项目进度风险。为了对项目成员进行更有效的管理,本文还针对关键链项目进度管理制定了考核激励制度。最后,本文将该模型在元东220kV智能变电站工程项目中进行了应用研究,取得了不错的效果,进度计划更为合理,进度控制更为有效。本文的研究将关键链进度管理方法充分应用到智能变电站建设项目的进度管理中,为同类型的项目提供借鉴和参考,具有很好的理论和现实意义。
[Abstract]:Project schedule management is the most important part of project management.Project schedule management is to ensure that the project in the specified quality, cost, time to complete the entire project.Project schedule planning and control is the core of project schedule management.At present, there are key path method, plan evaluation technique and earned value method in schedule management of electric power engineering.These methods can eliminate the influence of the uncertain factors of the project and manage the progress of the project effectively, but they also find some defects in their application, such as not considering the limitation of resources.Only focus on the management of each process, emphasizing the completion of each process on time, without considering the whole project; the project plan is too long, the project safety time is wasted and so on.In this paper, the research status of key chain schedule management at home and abroad is analyzed.Then it further analyzes the current situation of the progress management of intelligent substation construction project, aiming at the problems of the existing project schedule is too long, the safety time is wasted, the resource constraints are not enough and the schedule is difficult to control, etc.The key chain schedule management method is proposed to optimize the progress management of such projects.Then, on the basis of the research on the theory of critical chain, this paper applies the theory of key chain to intelligent substation project schedule management, and puts forward the key chain project schedule management model.The key chain schedule planning module and the key chain schedule control module are set in detail.In this paper, according to the characteristics of intelligent substation project, the Delphi method is used to calculate the project duration and the root variance method is used to calculate the buffer size in the calculation of project duration and buffer zone. These two methods are simple and easy to use.Then, the buffer zone is used as a bridge for project schedule planning and control. In project schedule control, three warning zones are set up in the buffer zone, and the project schedule risk is managed at different levels by combining the project organization and hierarchical management method.In order to manage the project members more effectively, this paper also establishes the evaluation incentive system for the key chain project schedule management.Finally, the model is applied to the Yuandong 220kV Intelligent Substation Project, and good results are obtained. The schedule plan is more reasonable and the schedule control is more effective.In this paper, the key chain schedule management method is fully applied to the schedule management of intelligent substation construction projects, which provides reference and reference for the same type of projects, which has good theoretical and practical significance.
