Title
Establishing Outsourcing and Supply Chain Plans for Prefabricated Construction Projects Under Uncertain Productivity.
Abstract
In prefabricated construction projects, unlike onsite assembly construction projects, structural components are produced in a factory environment. Thus, similarly to the manufacturing industries, the productivity of building components can fluctuate owing to human errors and machine malfunctions. Since the site demand must always be met, manufacturing is at times outsourced to supplement uncertainties in production. Furthermore, a storage facility between the factory and the construction site becomes indispensable to deal with components that are large in size, yielding a three-tier supply chain that is absent in traditional construction. The objective of this research is to determine the most appropriate production plan and the optimal outsourcing quantities for multi-prefabricated components produced in a manufacturing environment subject to uncertainties in productivity. A workflow including a two-stage stochastic programming model and a mixed integer linear programming model is established to resolve the above issues. The most favourable schemes for dispatching components and the variation of inventory are also determined. A large infrastructure built through the prefabrication method was selected as a case study to validate the models.
