A new multi-objective design approach is proposed for handling many different objective functions in the design problem of laminated composite plates. First, a number of various vibration and buckling eigenvalues are calculated for some discretized fiber angles of the plate by the Ritz method. These eigenvalues are taken to be the object functions. The second step is based on statistical treatment of the data. For each object function, the calculated eigenvalues for different fiber angles are normalized by the maximum value and then the deviated values are determined on the assumption that the eigenvalues are sujected to the Gaussian distribution with the standard deviation of 10 and average of 50. The optimal fiber angle, within the discretized values of fiber angles, is determined by examining the sum of the deviated values of all the object functions.
