An improvement on approximate solution to convex models of uncertainties

Qiu Zhiping, Gu Yuanxian ( Res. Inst. of Eng. Mechanics., Dalian Univ. of Technol., China )  
In terms of the eigenvalue problem with uncertain parameters, by means of nonprobabilistic, convex modeling combined with perturbation theory, an improvement is made on the first order approximate solution in convex models of uncertainties. Without calculating the derivatives of eigenvalues, the improved method not only can widen application of convex modeling, but also can greatly increase the efficiency of computations of the solution.
