why my workflow using optimization tool always stuck in 36%?

[lu_jin]

is that due to too many rows for O-input to the optimization tool?

thanks in advance

@lu_jin,

Could you please give more details about the problem.

I can't see the macro as well on the shared workflow. Could you share it?

Best regards,

Hi @lu_jin ,

I have run the workflow, it works fine on my notebook (64GB RAM,  4 cores), even though it takes some time (~ 14 minutes).  It's a memory consuming process, especially when you are using a high number of variables, I guess, it's related to the hardware capacity.

Maybe it is possible to "simplify" the model (reduce number of variables, constraints, ...)?

Best,

Roland
