Study on the Dynamic Planning of Production Strategy of Precast Concrete Components for Modular Integrated Construction

In recent years, modular integrated construction have gained more and more attention for cleaner and more efficient construction methods. But there are also many challenges in the development of modular integrated construction. Most of the current production operation planning in precast concrete components (PCC) plants is based on experience, and the management model is rough, with problems such as waste of resources and high costs. In order to improve the production efficiency of PCC in the manufacturing process, it is necessary to obtain accurate information on the quantity, type and delivery time of PCC at the time of production, and then make initial optimization of the production strategy. Then, based on the data returned in real time from the passive radio frequency identification (RFID) components pre-embedded in the production process, the deviation process is corrected and rescheduling is performed to dynamically ensure that the production strategy remains optimal. In this paper, based on the graph constrained crating algorithm, a production strategy planning model for PCC of modular integrated construction is established. Using breadth-first search (BFS) technology, sorting algorithm with variable weights and RFID technology, it can realize dynamic scheduling optimization of production strategy for prefabricated orders with many types and large quantities, and achieve high efficiency and sustainability of prefabricated production.
