Abstract:This paper presents an efficient algorithm for multi-objective optimization of large-scale structures. It is a direct extention of the method of centers for solving general nonlinear programming. At each iteration, we define a "moving target" for each objective function, to convert it to a level constraint and then the algorithrn calculates the center of the intersection of level constraints and original constraints. It is shown that the sequence of these centers will converge to a Pareto solution of a multi-objective optimization problem. Some examples are given to illustrate the proposed algorithm.
