A Missouri job shop has four

departmentsmachining

(M), dipping in a chemical bath (D), finishing (F), and plating

(P)assigned

to four work areas. The operations manager, Mary Marrs, has gathered the following data for the movement of material.

The number of workpieces moved yearly between work areas are:

	M	D	F	P
M		600	1,900	200
D			400	200
F				2,000
P

It costs

$0.75

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).

Part 2

a) LAYOUT PLAN

A:

Distance between work areas (departments) in feet:

	M	D	F	P
M		20	12	8
D			7	10
F				4
P

The yearly total material handling cost of the current layout presented in PLAN A =

Part 3

b) In Plan B, the proposal is to switch those departments with the high loads, namely, finishing (F) and plating (P), which alters the distance between them and machining (M) and dipping (D), as follows:

LAYOUT PLAN

B:

Distance between work areas (departments) in feet:

	M	D	F	P
M		20	8	12
D			10	7
F				4
P

c) In Plan C, the Machining (M) and Dipping (D) are also switched and the distances are as follows:

LAYOUT PLAN

C:

Distance between work areas (departments) in feet:

	M	D	F	P
M		20	10	7
