The production capacity is one of the key indicators reflecting the factory producing prefabricated components, and the production arrangement mode of the components will have direct effects on the production efficiency and capability of prefabricated components. This paper applies the simulation experiment using Anylogic for the better automatized external wall prefabrication line, to analyze and calculate the productivity of PC components under the free-beat and fixed-beat production arrangement modes, respectively, and to discuss the applicable conditions for different production arrangement modes.

The scale and number of prefabricated buildings are constantly expanding, and the type and number of components are required to increase greatly. However, the current component mass production standardization level is low, digital management level is not high, resulting in component production efficiency low and difficult to achieve the expected production capacity. In this paper, an improved genetic algorithm is proposed for the production scheduling optimization of PC component plant based on the actual situation of production line and the analysis of component scheduling process.
