Soru 11:

In the minimization models, the objective function is alternatively named profit function. The ultimate goal of minimizing something is to reduce loss or “cost”. In the minimization models, a line is drawn parallel to the objective function and near to the origin. This line should contain at least one point of the feasible region.
