Establishment and Application of Grey Model on Architectural Engineering Accident

The writers put forward the grey information model in order to forecast architectural engineering accident more accurately and solve the uncertain and occasional problem small sample,poor information" of architectural engineering accident system.The interchange of grey difference equation and differential equations realize the process in which continuous dynamic differential equation is built with the disperse data sequence in the paper,and we applied it to forecasting architectural engineering accident.The result shows that relative error σ,the error probability P and mean-square deviation ratio C satisfy the eligible demand;P and C also reach stair level.By simulation and precision measure,GM(1,1) model solve the uncertain problems of architectural engineering accident.The forecasting result shows that the number of engineering accident in Liaoning province is falling in the future,but it is not obvious,which calls for better safety supervision.
