The inevitable mistuning in aeroengine bladed disks can lead to considerable increase in vibratory amplitude and stress

and thus deteriorate the structural integrity and reliability. Therefore

the dynamic characteristics of mistuned bladed disks have been drawn great attention in both academic and engineering fields around the world. This paper presents a review of the modeling and analysis methods for mistuned bladed disks

with particular emphasis on the geometric mistuning of integrally bladed rotors and multistage bladed disks. The recent researches on mathematical representation and reduced-order modeling of geometric mistuning are introduced. Important developments and future research directions in this area are highlighted.
