Aiming at the problems of subjective factors weighting too much in many scheme evaluation methods, we try to explore an objective multi-scheme selection method.Firstly, we constructed the index evaluation system of the sealing and controling scheme, the weight of each index was determined by G₁ method. Then through the analysis of the language evaluation matrix of each decision expert, we determine the information subweights, fit subweights and discrimination subweights of each decision expert, each expert weight is determined in turn. Finally, we adopted the method of approaching the group ideal scheme, building multi-scheme evaluation model, and prioritizing the scheme. Real case analysis shows that this model can provide an effective auxiliary means for decision makers.
