Which variable do you consider to be the "linearization variable"? I tried your example and it solved OK,
Gurobi 6.5.0: optimal solution; objective 299000
1140 simplex iterations
plus 1 simplex iteration for intbasis
and in all the collections of variables Z, X, C, NM, Y there was at least one there was at least one variable that was not zero.

ive having a problem with my model .
The problem is I keep getting the value of the inearization variable is zero, although i wrote constraints to ensure not to have a value of zero always.
...
Any help ?
