A design of an engineering project is a process of constraint specification and satisfaction. An optimal design for a flexible assembly system can be regarded as a constrained optimization problem. The method of genetic algorithm is efficient and is used widely in the design of the complex systems in engineering. However, some additional difficulties exist in the process of using genetic algorithm to solve constrained optimization problems. The present paper discusses how to combine the human knowledge into the searching process through the constraints pre_handled and mutation library built with mutation operators. Thus, the optimal performances of the genetic algorithm are improved. Finally, an optimization is successfully used in the design of a flexible assembly system.
