Question

a) For the existing layout, the cumulative "load x distance" or "movement cost" = ______ feet.

b) Based on the flows shown in the matrix, one should expect that the centers A and __ will be next to each other as they have the highest numbers of moves between each other.

c) Based on the flows shown in the matrix, one should expect that the centers C and __ will be next to each other as they have the second highest numbers of moves between each other.

d) 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 __.

e) The cumulative distance based on the overall movement of parts between work centers for this layout = _______ feet.

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 C A 500 B 350 200 С D A B 480 D D 60 0 750 0 0 0 0 Figure 2. Existing Layout A B 30 30 С D 30

Answer 1

a.

Distance between A & B = 30

Distance between A & C = 60

Distance between A & D = 90

Distance between B & C = 30

Distance between B & D = 60

Distance between D & C = 30

Movement cost = $\sum Load * Distance$

Movement cost = 30*480 + 60*500 + 90*60 + 30*350 + 30*200 + 30*750 = 88800

b.

Moves between A & B = 480 + 350 = 830

Moves between A & C = 500

Moves between A & D = 60

Moves between B & C = 200

Moves between B & D = 0

Moves between D & C = 750

Based on the flows shown in the matrix, one should expect that the center's A and B will be next to each other as they have the highest numbers of moves between each other. (830 Moves)

c.

Based on the flows shown in the matrix, one should expect that centers C and D will be next to each other as they have the second highest numbers of moves between each other. (750 Moves)

d.

As we can see that, third highest moves are between A & C (500). These work centres should be close to each other.

Improved layout as follows:

B

A

C

D

In the improved layout, the work center that should be located between them is C

e.

.According to new layout,

Distance between A & B = 30

Distance between A & C = 30

Distance between A & D = 60

Distance between B & C = 60

Distance between B & D = 90

Distance between D & C = 30

Movement cost for this layout = $\sum Load * Distance$

Movement cost for this layout = 30*480 + 30*500 + 60*60 + 30*350 + 60*200 + 30*750 = 78000

The cumulative distance based on the overall movement of parts between work centers for this layout = ____78000___ feet.
