In order to solve the problem of combined Distribution of molds on the mold table in the production line of Prefabricated component, this paper proposes a method that combined improved Bottom-Left (BL) Placement Policy with the improved Electromagnetism-like Mechanism (EM) algorithm to solve the problem. Firstly, the mathematical model of the combined distribution of the mold on the mold table is established. The improved EM algorithm is used to optimize the order of the Prefabricated components. Secondly, according to the size of mold and mold table, the molds are distributed to the mold tables. An improved BL Placement Policy is proposed to determine the angle and position of molds on the mold tables. Finally, through the simulation test of the actual production enterprise’s instance data, the effectiveness of the proposed new method is verified to solve the problem of combined distribution problem of mold on the mold table.
