Incremental cost is an important bottleneck restricting the promotion and development of the prefabricated construction model. The main reason for its formation is the lack of linkage mechanisms in the production, transportation and assembly of prefabricated components. Starting from the perspective of supply chain integration and focusing on the production and transportation stages, a prefabricated component production and transportation collaborative scheduling model with the goal of punctual delivery and process time is established, which includes the process flow and batch characteristics of prefabricated components, and the model is solved by improved genetic algorithm. Finally，the feasibility of the model is verified by a data experiment. It is concluded that the model can effectively solve the production scheduling and transportation management of prefabricated components, and improve the synergy efficiency of both.
