3 Problem 2: An Emergency Room has five (5) bays for patients. The bays are labeled A-E. The layout is shown below. All of these bays share an ultra sound. The flow-between matrix shows the number of times in a day the ultra sound usually moves between each of these bays. The Unit cost is the cost to move the machine from bay to bay. a) Complete the distance matrix for the bays which have flow. b) Using CRAFT two-way exchange, indicate which bay pairs CRAFT would consider exchanging c) Compute the estimated difference in cost from the original layout to a layout in which bays A and E are exchanged.
