Abstract:In order to improve the precision of GM(1,1) power model,the improve GM(1,1) power model is established based on the background value optimum.The particle optimization algorithm is applied to solve the improve GM(1,1) power model.The application example indicates that the precision of improve GM(1,1) power model is higher than the GM(1,1) power model.So this method is feasible,effective and has important theory significance.
Keywords:GM(1  1) power model  background value  particle optimization algorithm  fitting precision
