The production of precast concrete (PC) component in factory is a very influential and complex work for the construction of the project. The rhythm of production is often delayed because the production process in most PC component factories is discrete at present. This study focuses on the production process of PC components and aims to propose regular scheduling and dynamic rescheduling models in prefabricated building project management. Based on the swarm-intelligence (SI) collaboration mechanism, the dynamic-interval synergy auction (DISA) strategy is proposed to improve contract net protocol (CNP). The genetic algorithm based on Tchebycheff (TCH) decomposition strategy is used to obtain the optimal production scheduling schemes. In addition, this model designs a coding mechanism for components based on Omniclass classification standard and the attributes of components are extended based on IFC extension mechanism. This model was verified in a PC factory. The experimental results showed that the decentralized negotiation mode with dynamic time window mechanism can avoid local optimization of schemes. Compared with traditional calculation method, this method could obtain more comprehensive and lower cost schemes. Based on the collaboration mechanism, with improved CNP and TCH strategies introduced, the dynamic model can improve the integrity and intelligence of PC factory.
