Research On Application Of Key Chain Technology In Schedule Management Of Linyuan Station Renovation Project

The reconstruction and expansion construction projects of large and medium-sized railway stations are generally characterized by large scale of construction,high investment amount,tight construction period and high safety risk.In order to ensure that the construction objectives proposed by the construction management unit of railway bureau can be completed on schedule,construction enterprises must improve the progress management level of the projects.As a comprehensive railway reconstruction project,the project of tongjean railway linyuan station has some problems in progress management.Critical chain technology can help the project schedule,balance the resource conflicts,improve the project’s ability to deal with all kinds of risk factors impact,based on this,it is necessary to use the critical chain technology to Lin Yuan station renovation project schedule management must be studied,in order to help improve project progress management level.This paper mainly takes the progress management and the key chain technology as the theoretical basis to carry out research around the linyuan station reconstruction project.First through comprehensive overview of Lin Yuan station renovation project of system,including the project general situation,the management goal,tissue,etc.,and analyzes the current management status,make the project schedule management problems that exist in the process,such as:unreasonable schedule,key resources supply,design change not in time uncertainty,etc.Second key chain knowledge relating with the station renovation project schedule management needs,design a suitable Lin Yuan station renovation project schedule management plan,specific content according to the actual situation of project management is to identify the key chain and buffer Settings,and set the buffer into the buffer and buffer components joined the improvement factor,the buffer management section,monitoring and warning from setting buffer interface point,hierarchical control and resource buffer management four Angle put forward a series of concrete methods.Then it evaluates the progress management effect of the improved linyuan station reconstruction project,and the evaluation result is good,indicating that the project progress management scheme has been designed successfully.Actual demand at the same time,based on the progress of the project management,project schedule management to establish a security system for the modification of the Lin Yuan station,concrete measures such as improving project management organization and system,strengthen management,technology and material PM aided management information system,etc,in order to help with someproblems in projects in progress management,ensure project completed on schedule.
