Question 1
One difference between the stepping-stone method compared to the Northwest-corner and intuitive method is that
◦ the stepping-stone method ALWAYS finds a lower-cost solution.
◦ the Northwest-corner and intuitive method guarantees sub-optimal solutions.
◦ the stepping-stone method ignores costs.
◦ the stepping-stone method never finds a feasible solution.
◦ the stepping-stone method guarantees an optimal solution.
Question 2
A transportation problem has improvement indices of 5, 4, 0, and -3. Which of the following is always true?
◦ The transportation matrix has four empty squares.
◦ The transportation model is at its ideal solution.
◦ The total cost saved by changing one unit on the route with an improvement index of 5 would be $5.
◦ The transportation model is at a feasible solution.
◦ The transportation model is at a feasible solution and the transportation matrix has four empty squares
