Hi,

Thank you for your excellent work!
However, it seemed that there was a mistake in the selection section.

 if selection_rand[i]<=qk[0]:
            population_list[i][:]=total_chromosome[0][:]
            break  # <- the break was weird
        else:
            for j in range(0,population_size*2-1):
                if selection_rand[i]>qk[j] and selection_rand[i]<=qk[j+1]:
                    population_list[i][:]=total_chromosome[j+1][:]
                    break  # -> should be moved here?

at line 88, why are the left-hand side and the right-hand side of the assignment operator the same?

Hi,
I am just wondering have you got JSP_dataset.xlsx for NSGA-II code.py ??

Thanks.

Hi Cheng-Man,

Did you consider demand parameter in this software and lot streaming optimization?

Thanks,

Thank you for the excelent work.
Looks like the outcome didn't respect the machine sequence constraints because for job J3, J4 and J5 the last operation should have been O9. Instead the solution returned as their last operation Machine 5, Machine 6 and Machine 7 respectively.
