【摘要】：电网是城市现代化建设的一项重要基础设施,坚强的电网为国民经济的发展提供强有力的保障。电网的投资建设规模大、覆盖广,对电网建设进行合理规划,对电网的建设工程项目进行有效的管控,将获得巨大的经济效益和社会效益;否则,如果城市电网规划不合理、投资建设控制不到位,将会给国家的经济建设和人民生活带来不可弥补的损失。工程进度控制是项目工程施工管理中的重要环节,对整个工程的实施与质量保障有着举足轻重的作用。项目进度作为衡量工程项目管理水平高低的重要经济指标之一,项目能否发挥其经济效益,与其是否能在指定的时间内交付使用密切相关,因此做好项目进度管理工作十分必要。本论文结合国内外项目管理研究现状,在传统项目施工进度控制理论研究的基础之上,对配电网架空线路工程施工进度管理现状及问题进行阐述,从解决管理机制落后、项目进度动态控制和优化意识不高、沟通协调不够等问题入手,突出关键链项目管理的必要性。本论文以“李营110kV配电网架空线路施工项目”为例,基于关键链项目管理,在对工程项目的工程特点、线路路径、施工方案认真分析的基础上,基于关键链理论对施工项目进行WBS分解,确定关键路径;采用最乐观完成时间的50%概率时间作为削减安全时间的工序时间;分析约束瓶颈,运用平行算法优先准则确定工程关键链;运用弹性系数法确定缓冲区大小,最终确定本工程的项目进度计划。通过上述关键链法,对其进度控制,通过在缓冲区设置绿、黄、红三色区间,通过项目风险预估、项目多层管理、调度管理、对项目管理人员进行绩效考核等方式,对工程项目进度进行控制。通过构建的控制管理模型,运用关键链法对李营110 kV配电网架空线路施工项目进度进行控制,为本工程的顺利完工提供保障,证明运用关键链技术进行项目进度控制在理论和实践上是可行的,今后可以在其他同类型的工程上推广应用。
[Abstract]:Power grid is an important infrastructure in urban modernization construction. Strong power grid provides a strong guarantee for the development of national economy. The scale of investment and construction of power grid is large and the coverage is wide. It will obtain enormous economic and social benefits to plan the construction of power grid reasonably and to control the construction project of power grid effectively. Otherwise, if the urban power network planning is unreasonable and the investment construction control is not in place, it will bring irreparable losses to the national economic construction and people's life. Project schedule control is an important link in project construction management, which plays an important role in the implementation and quality assurance of the whole project. As one of the important economic indicators to measure the level of project management, whether the project can bring its economic benefits into full play is closely related to whether the project can be delivered within a specified time. Therefore, it is necessary to do the project schedule management well. Based on the research of traditional project construction schedule control theory, this paper expatiates on the current situation and problems of construction schedule management of overhead transmission line project in distribution network, which is backward in solving the problem of management mechanism, combining the current situation of project management research at home and abroad, and on the basis of traditional project construction schedule control theory research. The project progress dynamic control and optimization consciousness is not high, the communication and coordination is not enough, and the necessity of key chain project management is highlighted. This paper takes "Li Ying 110kV distribution network overhead line construction project" as an example, based on the key chain project management, on the basis of careful analysis of the engineering characteristics, route path and construction scheme of the project, the paper takes "Li Ying 110kV distribution network overhead line construction project" as an example, based on the key chain project management. Based on the theory of critical chain, the WBS decomposition of construction project is carried out, and the critical path is determined. The 50% probability time of the most optimistic completion time is used as the working procedure time to reduce the safe time, the constraint bottleneck is analyzed, and the engineering key chain is determined by using the priority criterion of parallel algorithm. The size of buffer zone is determined by elastic coefficient method, and the project schedule is finally determined. Through the key chain method mentioned above, the progress of the project is controlled, by setting green, yellow and red areas in the buffer zone, through the project risk estimation, the project multi-layer management, the scheduling management, the performance appraisal of the project manager, etc. Control the progress of the project. Through the control management model constructed, the progress of the overhead line construction project of Li Ying 110 kV distribution network is controlled by using the key chain method, which provides the guarantee for the successful completion of the project. It is proved that it is feasible to use the key chain technology to control the project schedule in theory and practice, and it can be popularized and applied in other projects of the same type in the future.
