| [True/False Questions] If False, then underline the wrong part of sentence and correct it. (2 points each= 14 pts: If you do not correct the wrong part, you will get only 0.5 point.) Write down your answers in this Answer space below. 1. Sensitivity analysis is a useful post-optimality analysis attempting to evaluate the sensitivity of optimal solution to several changes in the model's parameters simultaneously. ) 2. When you apply the rounding approach, it is simple and certainly economical to derive an integer solution, and it may correspond to the true integer optimal solution with very little difference, however the rounded solution is feasible all the time.( ) 3. In the integer programming, when one subproblem's solution provides integer solutions AND you have better Z value from another subproblem which has non-integer solutions, you must continue to keep the next branches. ) 4. In Transportation Problem, in order to evaluate whether a degeneracy issue exists or not, the number of occupied cells must be equal to the number of rows + the number of columns - 1).( ) 5. In Transportation Problem, we can determine an optimal solution when all of the cost improvement index(CII) values (which represent the net change in total cost) are equal to 0 or positive.( ) 6. When supply exceeds demand in the transportation problem, the dummy row is added in the tableau with unit costs of O assigned to these dummy cells. ( ) The Hungarian assignment method can also be applied to problems with maximization objectives by transforming the given table into an opportunity cost table. 7. )
