The purpose of this paper is to prove the efficiency of the entropy model for estimating random imperfections in shells. The entropy model, which is based on an information maximum entropy criteria and a hypothesis of energy balance, is used to estimate a power spectrum density to random imperfections. The data banks of imperfections measured in cylindrical shells are already established, but such a kind of data base for other types of she'll structures are not yet established. We tried to simulate the power spectrums of imperfections in cylindrical shells using the entropy model and compared those with spectrums obtained from the data bank. These results lead to the conclusion that the characteristics of spectrums estimated by the entropy model give a good account for the measured ones.
