I have the following constraint:
            model.addConstr(aux1["O+", "1", m, t] == demand - sum(i1["O+", "1", m, t] for m in range(1, m)))
            model.addConstr(aux2["O+", "1", m, t] == gp.max_(0, aux1["O+", "1", m, t]))
            model.addConstr(aux3["O+", "1", m, t] == i1["O+", "1", m, t] - aux2["O+", "1", m, t])
            model.addConstr(I1["O+", "1", m, t] == gp.max_(0, aux3["O+", "1", m, t]))

which is representative of:is there anything wrong with using auxiliary variables?

  Hi Shahrzad,

  It looks correct.  You would not be able to formulate this using the current Gurobi API without using auxiliary variables.
