Abstract

Abstract: In order to solve the problem of the distribution of molds on the mold table in the production process of concrete prefabricated components, a method combining Bottom-Left Algorithm (BLA) and Improved Wolf Pack Algorithm (IWPA) is proposed. Improved Wolf Pack Algorithm is for optimizing the order of upper line and the mold used for each member is sequentially assigned to the mold table according to the upper line. BLA is used to determine the direction and position of the molds on the molds table. The WPA safari behavior is improved by introducing Levi's flying ideas and the Hamming distance-based wolf pack dynamic update mechanism is used to improve the Wolf Pack Algorithm. The wolf pack diversity is enriched and the search ability of WPA in the solution space is enhanced. An example test is carried out to verify the effectiveness of the method.
