Sudden risk predication model of construction supply chain based on data mining

In order to improve the accuracy of quantitative evaluation of construction supply chain burst risk, improve the ability of risk prediction, and effectively guide the prevention of construction supply chain burst risk, a quantitative evaluation and prediction model of construction supply chain burst risk based on data mining and multiple regression analysis is proposed. In this method, firstly, information acquisition and adaptive feature extraction are performed to characteristic quantity in quantitative analysis of sudden risks of the construction supply chain. Secondly, a stochastic probability density model is adopted to decompose characteristics of sudden risks of the construction supply chain, and risk evaluation and relevant predication are performed to the construction supply chain through internal control and extract control. The simulation results show that the method has high accuracy in the construction supply chain sudden risk prediction, with an average prediction accuracy of 88.86%, and the shortest time cost. It can be completed in only seven seconds in the prediction process. It has good global convergence and optimisation ability in the prediction.
