Question
A Missouri job shop has four departments-machining (M), dipping in a chemical bath (D), finishing (F), and plating (P-assigned to four work areas. The operations manager, Mary Marrs, has gathered thefolowing data for the movement of material. The number of workpieces moved yearly between work areas are: M DF P 00 1,900 300 -600 400 -1,900 1o It costs $0.50 to move 1 workpiece 1 foot in the job shop. For the layout design of the job shop, Mary has the current layout (Plan A) and two proposals (Plan B and Plan C).Explanation / Answer
Total distances moved from work area M
= 700 X 20 + 1900 X 11 + 300 X 6
= 14000 + 20900 + 1800
= 36700 FEET
Total distance moved from work area D
= 600 x 9 + 400 x 13
= 5400 + 5200
= 10600 feet
Total distance moved from work area F
= 1900 X 3
= 5700 ft
Therefore , sum total of all distances moved = 36700 + 10600 + 5700 ft = 53000 ft
Unit material handling cost = $0.5 / foot
Hence , yearly material handling cost
= Unit material handling cost x Total of all distances moved
=$ 0.5/ foot x 53000 ft
= $ 26500 feet
THE YEARLY TOTAL MATERIAL HANDLING COST OF THE PROPOSED LAYOUT PRESENTED IN PLAN C = $26500
THE YEARLY TOTAL MATERIAL HANDLING COST OF THE PROPOSED LAYOUT PRESENTED IN PLAN C = $26500
