Optimization of Flow Shop Scheduling in Precast Concrete Component Production via Mixed-Integer Linear Programming

Table 1

Operation time and weight value of the six components in each process.

Component number	Process operation time (h)					Delivery period (h)	Weight value (unit/h)
	Mold assembling	Reinforcement setting	Concrete casting	Mold removal	Finishing/repairing		Restoring time	Delay time
