【Abstract】 In this paper we present a multi-objective evolutionary algorithm for multi-objective bi-level programming problems.The linearly aggregated single objective programming in the lower level is solved with traditional optimization algorithms,while a multi-objective evolutionary algorithm based on NSGAII’s selection mechanism is used to solve the multi-objective programming problem in the upper level.The performance of the proposed algorithm is illustrated using a numerical example.更多还原
