I am currrently doing a project for my university and I have this type of error : CPLEX cannot handle MIQCP models with quadratic equality constraints like 'BtoWCosts_definition(91789)'.
I checked all my variables and my constraints but couldn’t find any “quadritic” ones.
And the error message tell me the error is in the definition of the variable “BtoWCosts” but again I can changed a lot of thing and It still didn’t work.
Here is the definition “ BtoW(W)* (NumberTrucks(W)*Truckload(W) )”
where Btow(w) is binary and the 2 others Intergers…
Thanks You in advance,

You will need some constraints like NumberTrucks(W) <= BtoW(W) * SomeBigM and the definition as NumberTrucks(W) * Truckload(W) which will result in 0 costs if BtoW(W) = 0.
