Question 13: A manufacturing concern has five departments (labeled A through E) located in a rectangular building as shown below: Suppose the following flow data, the unit cost data, and the distance matrix are given as follows: a) (4 points) Using the CRAFT two-way exchange procedure, indicate all the department pairs CRAFT would consider exchanging in the above layout. b) ( 5 points) Compute the estimated cost of exchanging departments A and E. (If you notice that the given Distance Matrix is not correct and you are thinking about correcting it to get the answer, then you are probably on the wrong path of solving it.)
