ED - Rooke, John ED - Dave, Bhargav AB - The objective of this study is to develop a framework for reducing precast fabrication inventory. The framework consists of three components. A time buffer evaluation is used to avoid fabricators losing capacity by considering demand variability. The second component, due date adjustment, shifts production curve closer to erection dates to reduce inventory. The third scheduling component arranges production sequences to achieve multi-objectives using genetic algorithms. The developed framework could reduce the level of finished goods inventory without changing production resources. It could also be used as a tool for creating and maintaining stability while attacking variability. KW - Precast fabrication KW - demand variability KW - inventory KW - scheduling.
