Prefabricated buildings are formed by producing prefabricated components in factories and then assembling them on-site [].Compared to the traditional cast-in-place concrete building production mode, prefabricated buildings are more conducive to improving labor efficiency, have a higher degree of standardization, and require less on-site wet work.1. Introduction. Traditionally, building construction takes place on the building site and construction materials, components, and elements are transferred from manufacturers to the site (Pervez et al., 2021).Conversely, prefabrication refers to the process of production, transfer, and preassembly of panels, elements, or modules at a Environmental and economic performance of prefabricated

As for China, the prefabrication system is in the early stage, prefabricated concrete is the main direction of the development. Our study is closely related to two streams of research: The PCs flow shop scheduling and the hybrid MTO-MTS production management. 2.1. PC production schedulingPrecast concrete (PC) slabs are widely used in the assembly of concrete residential buildings. The PC slabs are manufactured at the factory and then arranged in stacks for transport to the construction site for assembly. Currently, optimization of the stacking plans for PC slabs focuses on yard-space utilization and transportation Optimization of the Stacking Plans for Precast Concrete Slab
