In this paper, we discuss simultaneous optimization of the configuration and assembly process of a bridge structure using a genetic algorithm. The fitness function used to optimize the structure has many local minima. We propose a hybrid GA based on the "local reproduction method". We examine the performance and characteristics of the simultaneous optimization by studying three cases: (1) optimization of final structural configuration without considering assembly process, (2) optimization of the assembly process only and (3) simultaneous optimization of the final structural configuration and the assembly process. We demonstrate the effect of the assembly process on the optimum topology of the bridge structure and the applicability of this GA to multi dimensional optimization problems.
