Abstract: Clustering design module is a crucial step in module product design. In order to fulfill various demands in practice applications, this paper uses multi-objective optimization to cluster DSM. This method uses PSO to establish non dominated solution set, and then selects the best solution from the set. In order to adjust particle velocity in the optimization algorithm, this paper proposes a new easy encoded mode to encode DSM, then calculates relation information flow of each cluster in fitness function, and utilizes crowding distance to delete redundant solution in non dominated solution set. This paper uses a simple case to verify the method.
