Which of the following statements is false? The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination In a transportation problem, items are allocated from sources to destinations at a maximum costo In a balanced transportation model where supply equals demand, all constraints are equalities The transshipment model is an extension of the transportation model in which intermediate transshipment points are added do between the sources and destinations 2 Solving an integer programming problem by rounding off answers obtained by solving it as a linear programming problem (using simplex), we find that: All constraints are satisfied exactly The value of the objective function for a maximization problem will likely be less than that for the simplex solution. O The value of the objective function for a minimization problom will likely be less than that for the simplex solution The values of decision variables obtained by rounding off are always very close to the optimal values. O
