基于灰色理论的事故伤亡预测分析
Predictive analysis of accident casualties based on gray theory
摘要
Abstract
Using the theory of gray system prediction, a dynamic GM （ 1,1 ） model was establish based on cas- ualty statistics of the workers of a chemical company. The gray prediction for thousands of wounded workers in 2011 and 2012 was made and the prediction accuracy was verified. The results show that it fit a higher degree which provides a reference for the safety and production of enterprises.关键词
