Thanks Fred, I found the problem, but my model runs and the solution said it: MODEL hwlrp OBJECTIVE Z TYPE MIP DIRECTION MINIMIZE SOLVER CPLEX FROM LINE 255 **** SOLVER STATUS 1 Normal Completion **** MODEL STATUS 8 Integer Solution **** OBJECTIVE VALUE 2687897.8728 RESOURCE USAGE, LIMIT 10882.109 1...

Thanks Fred. The problem is that the model never finish. I have invested hours running it and anyone solution is found. I have reviewed that the problem happens when I put these constraints together: R12(t,w).. qt(w,t)=E=sum((v,g),xcag(g,t,v)*cmv(w,v)); R13(t).. sum[(w,m),(qtrat(w,m,t))*(1-alpha(w,m...

Thanks for your answer Fred. I did it and it's ok.

Hello, I have non-linear constraints in an LRP model and I want to make a linearization and solve it with CPLEX. This is the constraint: R(t).. sum[(w,m), (q(w,t) * trat(w,m) * (1-alpha(w,m)) * (beta(w,m)) ]=E= sum(r, Tr(t,r) ) q(w,t) = Continuous variable trat(w,m)= Binary variable alpha and beta h...

Hello,

I have a LRP model with additional characteristics. GAMs shows that my model has written correct but when it runs some items shows infeasible and I never have a solution.

¿What could be the error?

Thanks
