Application of fuzzy math in cost estimation of construction project

Abstract

In order to estimate the construction project cost more accurately and rapidly, this paper puts forward a method of cost estimation of construction project based on fuzzy mathematics. From the construction project cost analysis, the study sums up the impact factors of project cost, establishes estimation model using the method of fuzzy mathematics, and estimates the similarity nearness degree of the project to be estimated and the built project through comparison with typical engineering cases, and realizes the cost estimation with the principle of choosing the nearest, and the dynamic coefficient is used for estimation results correction. From the example, we can see that the model for cost estimation investment in construction project established with fuzzy mathematics method is easy to use with good applicability, which can realize rapid predict the estimated investment in construction project, satisfy the requirement of accuracy, enhance the management level of construction and the competition capacity of construction enterprise.
