```The production schedule for a certain part calls for manufacturing
approximately 750 units per week. While there is some fluctuation in this
requirement, it is extremely small. The operation sheet reveals that production of
the part calls for five (5) operations to be performed on five different machines.
The requirements for these operations, adjusted for delays, labor, efficiency,
and expected scrap, are as follows:
Operation Number
Required Time per Unit (hrs)
1
0.095
2
0.200
3
0.197
4
0.098
5
0.100
a.
Calculate the number of machines required to perform each operation
if the plant is scheduled to work 40 hours per week.
b.
What kind of layout (process or product) would you recommend for the
processing of this part?
c.
Prepare a sketch of one possible arrangement of these machines.
Explanation:
 You need to produce 750 units in a week, using these 5 machines.
 First convert the hours into seconds…
 Determine how many machine 1, machine 2, machine 3, machine 4 and
machine 5 to be used to produce approximately 750 units in a week.
 Consider the bottleneck between machines 1 and 2 and machines 4 and 5.
What are you going to do?
 HINT: number of machine is less than 22 machines.
