Application Of The Wavelet Analysis In The Fault Diagnosis Of Rotating Machines

With the rapid warming of the real estate market, construction market of unprecedented prosperity, the direct price competition become the primary means of competition, cost management has become construction enterprises in the competition the primary means of survival。The construction cost management is the core of the project cost management, therefore, how to effectively manage a construction project cost companies the most important issue to obtain a competitive advantage。In this paper, China's construction enterprises from the project cost management problems start, put forward the need for research。Secondly, this article from the surface to the point along the way, the project leads to the theory of cost management Project cost management of construction related businesses theoretical content, introduce Jiexi construction cost management company status, problems and problem analysis shows that construction companies project cost management status and risks。After the establishment of the use of P3E / C project management software using earned value method as the main control methods of quantitative analysis model, the construction company Jiexi H project cost management for dynamic, holistic assessment of the construction enterprises to establish rigorous cost evaluation , cost control systems provide a solution。Jiexi construction company by H project construction cost management studies, project cost management proposed a solution: real-time implementation of the project concerns the progress of the project cost and the dynamics between the two, focusing on cost control in target cost implementation。Project construction cost management throughout the project's construction period, is a dynamic management process, from project bidding information received since the project began the construction cost management。Therefore, construction companies should adhere to the implementation of the project cost management, project cost as the project manager an important assessment indicators of economic responsibility, after completion of the project, through assessment and analysis to confirm the completion of the project cost, and carefully to achieve reward and punishment。Manager of the project manager, project manager of the engineering team, engineering team to team, team of individuals, one an assessment of the cost through in the end. As long as the system put in place effective measures, the company benefits, target cost and personal interests to hang hook, the real implementation of the responsibilities, rights, benefits, cost management will be able to put into effect.
