Algorithm 4

DU-1.

	Step 1: same as Step 1 of DU-GA;
	Step 2: for each individual, apply algorithm CA-D. Calculate the fitness value for individuals in the population by taking as the fitness function.
	Step 3-Step 4: same as Step 3 - Step 4 of DU-GA;
	Step 5: output the processing sequence, batching decision, and delivery routings of the best solution based on fitness function . Calculate the corresponding objective function .
