Abstract: On the basis of considering the degree of importance of decision-making experts,the new importance based ordered weighting geometric(I-IOWG) averaging operators are proposed.They are applied to aggregate the judgment matrices information provided by the experts.It is proved that the combination judgment matrices aggregated by I-IOWG operator keep the reciprocal property.The compatibility,satisfactory compatibility and relations between compatibility and consistency of the combination judgment matrices based on I-IOWG operators are studied.Under the condition that each judgment matrix has the satisfactory compatibility with corresponding characteristic matrix,the property that the combination judgment matrix can keep the satisfactory compatibility is given.It shows that it is scientific and feasible to apply the I-IOWG operators to aggregate information in the group decision-making.
