Hello,
I'm trying to model a constraint and that is being so complex to me.
Is there any way to model a constraint like the follwing in GLPK?
I need to restrict that the sum must be equal or greater than Min[j] otherwise 0.
{j in T, i in B}: sum{k in S} f[i,k]*P[j,k] >=Min[j]
OR
{j in T, i in B}: sum{k in S} f[i,k]*P[j,k] =0
Thank you,
Tiago
