Abstract :Spherical fuzzy set is the generalized structure over existing structures  of fuzzy sets to deals with uncertainty and imprecise information in decision-making  problems. Viewing the effectiveness of the spherical fuzzy set, we developed a  decision-making algorithm to deal with multi-criteria decision-making problems. In  this paper, we extend operational laws to propose spherical fuzzy Choquet integral  weighted averaging insert ignore into journalissuearticles values(SFCIWA); operator based on spherical fuzzy numbers. Further,  the proposed SFCIWA operator is applied to multi-attribute group decision-making  problems. Also, we propose the GRA method to aggregate the spherical fuzzy infor mation. To implement the proposed models, we provide some numerical applications  of group decision-making problems. Also compared with the previous model, we  conclude that the proposed technique is more effective and reliable.
