  In this paper, combined with the degradation and monotonicity of parameters
of Hamacher operation and the advantages of the correlation between input
parameters of Heronian operators, IVq-ROFHHMWA and IVq-ROFHHMGA operators,
which are the fusion of Hamacher and Heronian, are proposed, and their
properties are studied. Finally, a group decision-making method based on
IVq-ROFHHMWA operator is proposed. The implementation and comparative analysis
results show that the operator and group decision-making methods proposed in
this paper are effective and feasible.
