摘要
Abstract
According to Vague sets and its proximity calculation, this paper establishes a new fast estimating model of the construction cost. Firstly, the existing similar projects have been selected from the historical data. Secondly, the main characteristic factors which may influence project cost are selected to establish the corre sponding characteristic value matrix. Based on interval integrated unit price, the Vague sets matrix of existing project is founded. Similarity degree of all the existing and designed projects is calculated. Through the cost in dex and maximal similarity project, the designed project cost has been estimated. Finally, the validity and accu racy of this model have been proved by practical data.关键词
