Abstract: To optimize the production scheduling problem of prefabricated components in prefabricated buildings,the production process of prefabricated components from the perspective of whole production supply of prefabricated component was analyzed,and a mathematical model of production scheduling of prefabricated components with the optimization evaluation criteria of completion time and penalty cost was established by considering the resource constraints in the production process.A novel Multi-Objective Hybrid Symbiotic Organisms Search(MOHSOS)algorithm was designed to solve the model for optimizing the production planning and resource allocation of the prefabricated components to achieve the purpose of reducing costs and improve the production efficiency.The effectiveness of the proposed model and algorithm was validated by an example of prefabricated housing project.

Key words: precast construction, production scheduling of prefabricated component, multi-objective optimization, hybrid symbiotic organisms search algorithm
