The characteristics of swarm evolutionary mechanism were analyzed, and a corresponding product configuration model was proposed. In order to select appropriate queen and male bees, a selection operator was established via similarity evaluation technique. A crossover operator was established to inherit useful components through components traversal, and a mutation operator was also established so as to configure individualized components based on the topological sort algorithm of constraint directed graph. The method of fitness evaluation was put forward by using estimated elements. The strategy and method were effective in an instance of the product called bridge crane.
