Claim One:
1. A computer-implemented method of performing a multi-objective evolutionary algorithm (MOEA) based engineering design optimization of a product, said method comprising: creating an archive in a storage device coupled to a computer system configured for performing the MOEA based engineering design optimization, the engineering design optimization comprises a plurality of generations in accordance with an evolution scheme of MOEA, each of the generations containing a set of product design alternatives in a predefined design space of the product; obtaining a corresponding set of solutions by evaluating each of the product design alternatives in accordance with design objectives; updating the archive with one or more non-dominated solutions after said each of the generations, said one or more non-dominated solutions being determined from the corresponding set of solutions and the archive's existing members; creating a termination criterion of the MOEA based optimization from an optimization performance indicator derived from the archive's update history; and designating the non-dominated solutions in the archive as a set of optimized product designs when the termination criterion has been met.
