Abstract: This paper analyzes the functional requirements of a BIM based intelligent scheduling and control system for precast production of prefabricated residential buildings. First, the current process of scheduling and control of precast production is analyzed and modeled. Then, based on the problems existing in the current process and the latest technologies such as BIM and multi-agent systems, the process is updated and a new process model is established. Finally, the functional requirements of the system are analyzed based on the new process model. Consequently, 37 functional requirements are obtained and presented, which lays the foundation for further development of the system.
