Research On Cost Management Issues In 4G Network PTN Two-plane Construction Project

With the explosive growth of mobile Internet data flow,the 4G network construction scale is expanding,and bandwidth requirements,the main mobile operators China mobile in Shanghai,expanding the 4G network construction scale,to provide users with good mobile communication service,set out to 4G networks PTN two planar construction project.In the engineering project cost management is of vital significance,also is the key project profit or not.During the whole process cost management in the project throughout,reflected in the cost management system,cost control,quality control,safety control,progress control,etc.,but is not only exist independently and implementation of all aspects,but the mutual restriction and unified.Determines the direct economic b enefits of the project cost management,reflect the project management level and management efficiency.This paper first describes the development of 4G network and the introduction of PTN technology are introduced,and then analyzes the status of the project cost management at home and abroad,and then to the 4G network PTN second plane construction project as the research object,to decomposition analysis of cost management,project cost management problems were summarized.Through the extensive reading of the related cost management theory and engineering practice literature,combined with the operation of the actual project,the project cost efficiency is summarized and analyzed,the cost management measures are optimized,and the micro-project of the 4G network PTN two-plane construction project A variety of costs to calculate the results before and after the comparison,and finally calculate the actual profit than the budget profits more than three points of the return,get relatively satisfactory results.Based on the previous research results,this paper constructs and consumes the cost management system of this project,establishes an effective cost management system and improves the cost management.Based on the research results of 4G network PTN two-plane construction project,Awareness,so that the cost management work is justified to ensure that.In the cost control research,we mainly plan the construction cost plan with WBS(Working Structure Decomposition),OBS(Organizational Structure Decomposi tion)and CBS(Cost Structure Decomposition)to estimate the preservation and target profit as the basis for controlling the production cost.In the progress control study,according to the project progress schedule(PMS)and work structure decomposition(WBS)to determine the task,the expected task duration,schedule cost control through the determination,adjust the task of the process and duration to improve work efficiency.In the quality control research,in accordance with the quality of the project entity to produce time control,in the control and control.The project to take these measures,the project can be carried out smoothly,and achieved the desired economic benefits.
