Abstract
In view of the traditional forecasting methods of project cost, there are some limitations and uncertainties. In the case of the historical data is not complete, and it requires more quickly and accurately the cost of the project. Therefore, with the help of the grey system theory, the paper puts forward a new method of project cost prediction based on Grey System Theory. Firstly, for the problem of GM (1, 1) prediction of single data, GM (1, N) prediction based on grey system theory is proposed; Secondly, by using GM (1, N) model, the dynamic relationship of each factor is found out, and the development and change of multiple behavior variables are predicted. Finally, according to the actual situation of project cost, the GM (1, N) prediction model is established. Compared with the traditional GM (1, 1), GM (1, N) prediction model improves the precision, and it has a certain application value.
