Munson Manufacturing, in Gainesville, Florida, wants to arrange its four work centers so as to minimize interdepartmental parts handling costs. The flows and existing facility layout are shown in the figures below. Figure 1. Parts Moved Between Work Centers D B D ABCD 450 550 60 350 0 Figure 2. Existing Layout B C D 30 225 0 0 725 0 0 a) For the existing layout, the cumulative "load x distance" or "movement cost" feet (enter your response as a whole number). Based on the flows shown in the matrix, one should expect that the centers A and each other. Based on the flows shown in the matrix, one should expect that centers C and between each other. will be next to each other as they have the highest number of moves between will be next to each other as they have the second highest number of moves b) The aim is to improve the layout so that the total "movement cost" can be reduced. Functional locations for A and D have been fixed. In the improved layout, the work center that should be located between them is: A 30- 30- D -30- The cumulative distance based on the overall movement of parts between work centers for this layout = feet (enter your response as a whole number).
