I scale the lower and upper bound.
But after execution it is said no super basic variables (infeasible solution).
What could be wrong?

Re: Error 142 suffix is not allowed
I run the new code.
However, it said an initial function value is too large (larger than 1.0E+10).
It suggests to scale the variables and/or equations or add bounds.
I tried to scale down the scalar (crude oil feed and demands), however the result is the same.
What should I change?
Thank you.

Re: Error 142 suffix is not allowed
Thank you Renger for your suggestion. May I ask again? I have done some revision to the code as following : Sets s "CDU cuts" /offgas,LSRN,HSRN,SRK,SRMD,SRGO,Res/ j "type of k" /k0,k1,k2,k3,k4/ i "type of a" /a0,a1,a2,a3,a4/ o "cut-point temperature of s" /x1,...

Error 142 suffix is not allowed
Hello everyone, I am a new GAMS user. I have tried to model my case using GAMS but I am still in the learning process. Sets s "CDU cuts" /offgas,LSRN,HSRN,SRK,SRMD,SRGO,Residue/ j "type of k" /k0,k1,k2,k3,k4/ i "type of a" /a0,a1,a2,a3,a4/ Parameter x1 'cut-point temper...
