| "High turnover",along with the expansion of real estate companies,is one of the most popular words in recent years.It requires real estate companies to speed up the high-speed turnover of funds,accelerate the completion of each investment project,and realize project income output as soon as possible Output is invested in new investment projects.Also as an asset-heavy industry,under the "new normal" of the domestic economy,electric power companies have to shift from ignoring costs and gains and rude investment expansion to facing the problem of how to achieve "high turnover".Among the projects invested and constructed by power grid companies,the most widely covered are distribution network projects,especially 10 k V distribution line construction projects.Once effective management and control are implemented,huge economic and social benefits will be obtained.Project schedule control is an important link in project construction management,and it plays a pivotal role in the implementation and quality assurance of the entire project.Project progress is one of the important economic indicators to measure the level of engineering project management.Whether the project can exert its economic benefits is closely related to whether it can be delivered and used within the specified time.Therefore,it is necessary to do a good job in project progress management.This thesis combines the status quo of project management research at home and abroad,and on the basis of the traditional project construction schedule control theory research,expounds the status quo and problems of the construction schedule management of overhead line projects in the distribution network,highlighting the necessity of critical chain project management.This paper takes "A Distribution Network Overhead Line Construction Project" as an example.Based on the project overview,construction procedures,and organizational structure of the project,combined with the critical chain theory,the project is decomposed by WBS and the critical path is determined;in order to further accelerate the return on investment,The critical path is optimized twice;the 50% probability of the most optimistic completion time is used as the process time to reduce the safety time;the constraint bottleneck is analyzed,and the parallel algorithm priority criterion is used to determine the engineering critical chain;the elastic coefficient method is used to determine the buffer size,and finally Determine the project schedule of this project.In order to further effectively implement the project schedule,the green,yellow,and red color intervals are set in the buffer zone,and the project risk estimation and performance evaluation methods are used to achieve effective control of the project schedule.Through the constructed control management model,the critical chain method is used to control the progress of the A distribution network overhead line construction project,which provides guarantee for the smooth completion of the project,and proves that it is feasible in theory and practice to use critical chain technology to control the project schedule,It can be promoted and applied in other projects of the same type in the future. |
