Study On Project Schedule-Management Of Nanning City Youyi Road Extension Cord Reconstruction

Project schedule management is an important aspect of project management, and it is one of the important measures to ensure the project schedule to be completed or reasonably arrange the resource supply and save the project cost. The Youyi road in Nanning City, extension line expansion project schedule management as the background, using in the WBS for project gas decomposition, and at the same time with the aid of to the network diagram drawing method proposed construction project of the main program, further integration scheme is proposed for construction project schedule plan and optimization scheme, to ensure the project in a specified time guarantee both quality and quantity of construction completed.First of all, the paper expounds the current situation of the progress management of the extension project of Nanning Youyi Road, and analyzes the existing problems and the influencing factors of the project schedule management. This paper briefly introduces the project background, project general situation and current situation of the extension project of Nanning Youyi Road extension line. This paper introduces the characteristics and difficulties of the project, focusing on the problems of the project schedule management and the factors affecting the project schedule management.Secondly, it puts forward the plan of the extension project of Nanning Youyi Road extension project, including the principle of decomposition, the decomposition of the work structure and the process of the work structure decomposition. And Youyi road of Nanning city extension line expansion project for activity sequencing and duration estimates, Youyi road of Nanning city to extend the line expansion project progress plan optimization, including schedule optimization and resource optimization.In the end, the paper puts forward the progress control method of the extension project of Nanning Youyi Road, which includes the control, the control and the post control. The project schedule control measures of Nanning Youyi Road extension project are put forward, including the organizational measures, technical measures, and resource protection measures. Then the deviation analysis and adjustment of the extension project of Nanning Youyi Road extension project are carried out.Based on the Youyi road, Nanning City, extended the line to change the exupansion project and construction management of whole process tracking, research, analysis and comparison, it is proposed that the promote the smooth implementation of the project schedule management measures and countermeasures, at the same time, it has theoretical reference and practical guiding significance for similar engineering project schedule management.
