Optimization of Precast Production Planning using

2014-3-31  Construction projects adopting prefabrication method are feasible to reduce project uncertainties by producing components in factories and transported to construction site to satisfy installation demand. In order to create project plans, designers and planners should manage available resources and select appropriate ways to produce, store, transport, and install components. This study adopts two new ideas which are prefabrication configuration and component groups to optimize precast project resource cost. Based on these concepts, an MIP optimization
