Hi everyone
I’ve got a problem while modeling my problem and I wanted you to help me, if you can so:
My model contains a quadratic term in the objective function and this makes my Linear model non-linear.
I tried to write the quadratic term separately as a condition and use its result as a first-order term in my objective function to make my model linear, like this:
Cost =e= sum(g,a0Coeff(g) + bCoeff(g)*Pg(g) + cCoeff(g)*Pg2(g))
…
Pg2(g) =e= Pg(g)*Pg(g)
but while debugging, I’ve encountered this message:
Error 143: a suffix is missing
I’ll be so thankful if anyone could help me
