Aiming at small batch and multi-type electroplating production scheduling system with flexible process, an adaptive clonal competition algorithm(ACCA）is proposed. The capability of searching the global optimal value and the local optimal value of the new algorithm can be adjusted through the function between the cloning and mutation probability and the number of iterations. Besides, the population diversity of the adaptive clonal competition algorithm can be ensured through the competition mechanism, the elite migration mechanism and the raising new members mechanism. Compared with traditional clonal selection algorithm, adaptive clonal competition algorithm has higher searching ability and faster convergence speed.
