The Application Of Neural Networks In The Estimation Of Project Cost

With the development of Chinese reform and market economy, construct enterprises confront much chance and flinty challenge as the same time. It is more obvious that competition machine-made of present-day market economic requests high efficiency in order to pick up tender scheme quickly, but traditional budget method and actual count soft must cost much time to do it. It becomes focus how to solve the problem in construction kingdom, As the same time, the owners are more interest in rapid cost evaluation, because it is vital for them to assert the price of project, In deferent construction phases, such as project evaluation phases before construction, principium design phases and shop drawing phases, especially the evaluation before construction is important because it is base point for us to control costo For owners, they can not only assert the price of project before design biding, but also assert the bid mark before construct bidingo In the recent years many scholar struggled to explore and achieved muchWith the development of Neural net and fuzzy math, they pioneer new world for us to realize rapid evaluation of project, The paper explain the combine principle between neural net and fuzzy math, and establish the evaluation modle based on fuzzy neural net and budget of project cost, and establishes the residence evaluation modle based on the modle, and illuminates its implement and practicability.
