For the layout design of the job shop, Mary has the current layout (Plan A) and two proposals (Plan B and Plan C) a) LAYOUT PLAN A: Distance between work areas (departments) in feet: 22 12 8 6 10

Explanation / Answer

Solution:

The yearly total material handling cost is calculated as,

Material handling cost = (Number of workpieces moved yearly x Distance between work areas) x Cost of moving 1 workpiece 1 foot

(a) Layout Plan A:

Material handling cost = [(700 x 22) + (1900 x 12) + (400 x 8) + (500 x 6) + (200 x 10) + (2000 x 4)] x $0.50

Material handling cost = $27,200

(b) Layout Plan B:

Material handling cost = [(700 x 22) + (1900 x 8) + (400 x 12) + (500 x 10) + (200 x 6) + (2000 x 4)] x $0.50

Material handling cost = $24,800

(c) Layout Plan C:

Material handling cost = [(700 x 22) + (1900 x 10) + (400 x 6) + (500 x 8) + (200 x 12) + (2000 x 4)] x $0.50

Material handling cost = $25,600

(d) The best layout from the cost perspective is PLAN B.
