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

Real estate market is confronted with formidable challenges and macroscopic governmental regulation is strengthen in 2010. Competition Heats up with each other real estate in new environment, Operational management is the most important problem. Investment decision and design stage is the key of investment control before construction.After the investment decision,design stage is the key of investment control before constructionSo, This essay focuses on cost optimal control in engineering design stage for real estate.The Major Content is cost optimal of the project design stage,which is the more important stage and the first step for project investment. Then there is an analysis of losing spread of for design optimization and it proposes optimizing measure of the design optimum.At last, this essay makes a concrete analysis of the project cost on design supervision,quota design and optimal design,and puts forward excellent suggestion.. Design supervision make construction projects investment on the basis of science, standard,and high-efficiency,it attain the goal of investment control and improves management of engineering construction.Quota design is the important method of the real estate project construction cost to control. It is beneficial to reinforce project cost consciousness for designers.but controlling of cost of real estate projects by quota design is a comprehensive problem,we can't economizes the project investment in a one-sided way,and must correct treating for antinomy and unification of technigues and economy on saving cost. Optimal design has important role in controlling project cost. With the premise of satisfying architectural function and architectural art, structures design must be economic and acceptable.Combining with practice project of Structural Design for Shenzhen xiangmi Mountain and Steel Design for Jindi company.This paper puts methods and measures of construction cost control from design phase. Realizing scientific decision-making and the optimal design and production of the project, which reachs the goal of reducing the cost of real estate under the precondition of ensure analysis quality and safety.
