Abstract: | This paper elaborates the basic concept and primary methods of grey system theory and conducts case study on forecasting of estimate of construction cost by GM ( 1.1 ) model built on grey system predication theory. With integration of this theory and computer technology the average precision in prediction results reach Class Ⅰ, which shows high accuracy and reliability in forecasting and can provide scientific basis for decision making on approval of project proposals |
