A Heuristic Solution Approach to Order Batching and Sequencing for Manual Picking and Packing Lines considering Fatiguing Effect

Algorithm 2

Initialization module in improved genetic algorithms.

	Initialization: ; unassigned batches with index ;
	completion time total picking lines ;
	vector , objective value
	While ( total batch number ) do
	if () then
	follow rule 1 to choose picking line and batch
	get randomly in unassigned batches
	follow rule 2 to choose picking line and batch
	choose subset from randomly
	{item quantity
	setup time
	processing time setup time
	finishing time
	End
