“…It is also necessary to emphasize the importance of information interoperability between resource planning systems of different supply chain bodies [75]. One of the most common risk factors is late delivery due to inconsistent logistics information caused by human error [76]. Successful supply chain strategic research and project evaluation contribute to stakeholders grasping market opportunities and challenges, reducing total cost, improving construction efficiency, seizing the construction market, and further winning development.…”

Prefabricated construction (PC), with the characteristics of green, environmentally friendly, energy saving and high production efficiency, is attracting more and more attention from all over the world. Supply chain management is closely related to the application efficiency of PC, but only in the last three years has this interdisciplinary research received due attention. The prefabricated construction supply chain management (PCSCM) have not received enough attention. Especially recently, the related literature shows explosive growth. This paper adopted the method of systematic literature review through the tool of bibliometric statistics. And we reviewed 152 articles from 2001 to 2018, with the goal of understanding the current situation, trends, and gaps in PCSCM research, and a framework is proposed to promote its development. First, the study discussed the four themes of clustering, concentrating mainly on strategic research and project evaluation, PC supply chain process design and optimization, supply chain integration and management, and the application of advanced technology. Then, the research gaps and conceptual development framework to promote PCSCM were reported. Only through the coordinated development of technology, market circumstances, and decision-making level of participants, can the PCSC form an integrated whole, so as to optimize the efficiency and sustainability of prefabricated construction industry and improve its level.

“…In general, scheduling is crucial for the production of precast components (precast production for short hereafter), which consists of master production scheduling, material requirement planning and shop floor scheduling. Among them, shop floor scheduling is the most detailed and difficult one, in which production tasks are assigned to specific workshop sections, teams or even operators (Yang et al, 2016).…”

Flowshop production is adopted as the major type of production of reinforced precast concrete components and it has higher requirements on shop floor schedules than other types, especially that from rescheduling. However, up to now, very few approach for the optimization of the shop floor rescheduling has been proposed in spite of its vital importance. This research proposes an approach for optimizing shop floor rescheduling of multiple production lines for flowshop production of reinforced precast concrete components. The approach comprehensively utilizes the over-assigned time, which is the difference value between the assigned production time and the estimated one of a production step for a precast component to deal with production emergencies. Meanwhile, it keeps the adjustment of schedules at minimum to avoid massive material re-dispatch. First of all, the optimization objectives and constraints of optimized shop floor rescheduling of multiple production lines for flowshop precast production are analyzed and a mathematic model is thus formulated. Then, the solver of the model is established by using genetic algorithm. Finally, the approach is validated by case studies. It is concluded that the approach contributes to the effective and efficient optimized rescheduling of multiple production lines for flowshop precast production.

“…There are two basic types of precast component production systems in a precast plant, namely, the fixed location production/stationary system and the flow shop production/traveling system [19][20][21]. For fixed location production, all the activities are performed in a particular workstation either by the same team or different teams.…”

“…Prata et al proposed a model based on integer linear programming to schedule the production of the beams so as to minimize the losses in a minimal time by taking into account the constraints inherent in the forms and beams [18]. Yang et al proposed a flow shop scheduling model of multiple production lines for precast production and developed an optimization approach to facilitate optimized scheduling by using genetic algorithm [19].…”

“…The first category focuses on optimizing the specific process for various distinct precast production methods, such as the roll-cutting process of the filigree wide-slab method [18] and the layout process of composite precast concrete members for precast concrete in situ production [17]. The second category focuses on traditional precast production methods for optimizing the production plan based on the job shop/flow shop scheduling problem [12][13][14][15][16]19], which mainly emphasize the flow variability between processes under special constrains such as limited labor and mold [14]. However, strategies for improving the specific production processes for traditional precast production methods are generally neglected in current literature.…”

Precast concrete comprises the basic components of modular buildings. The efficiency of precast concrete building component production directly impacts the construction time and cost. In the processes of precast component production, mold setting has a significant influence on the production efficiency and cost, as well as reducing the resource consumption. However, the development of mold setting plans is left to the experience of production staff, with outcomes dependent on the quality of human skill and experience available. This can result in sub-optimal production efficiencies and resource wastage. Accordingly, in order to improve the efficiency of precast component production, this paper proposes an optimization model able to maximize the average utilization rate of pallets used during the molding process. The constraints considered were the order demand, the size of the pallet, layout methods, and the positional relationship of components. A heuristic algorithm was used to identify optimization solutions provided by the model. Through empirical analysis, and as exemplified in the case study, this research is significant in offering a prefabrication production planning model which improves pallet utilization rates, shortens component production time, reduces production costs, and improves the resource utilization. The results clearly demonstrate that the proposed method can facilitate the precast production plan providing strong practical implications for production planners.
