Hello All,

How can avoid multiplying two variables in MINLP like;

Eq1(c.l)… p =e= sum((j,s), beta(j,s))

Eq2(s,j,c,l)… q =e= sum(r, x(r,s,j,c,l))

mflow(c.l)… p * q =l= sum(j, alpha(c,j)* y(j,c,l)

where

y(j,c,l) is binary variable

x(r,s,j,c,l) is positive variable

beta & alpha are parameters

This set of eq definition gives in-feasible soln.

Any suggestion?

THANKS & REGARDS,
