Question 1:
S7.14 Klassen Toy Company, Inc., assembles two parts: Part 1 is first processed at
workstation A for 15 minutes per unit and then processed at workstation B for 10 min.
per unit. Part 2 is simultaneously processed at workstation C for 20 min per unit. Work
stations B and C feed the parts to an assembler at workstation D, where the two parts are
assembled. The time at workstation D is 15 minutes.
a)
what is the bottleneck of this process?
b)
what is the hourly capacity of the process?
Question 2:
Woodland Furniture Company operates a complex production line to manufacture
custom-made wooden furniture. The production process involves multiple workstations
with various processing times. The line consists of five workstations: A, B, C, D, and E.
Part X is processed at Station A (18 min/unit) and then at Station B (12 min/unit)
sequentially, while Part Y is processed at Station C (15 min/unit) and then at Station D (22
min/unit) sequentially. Once both parts, X and Y, reach Station E, they are assembled into
the final product on two assembly lines, each processing at a rate of 20 minutes per unit.
a)
Determine the bottleneck workstation(s) in this production line.
b)
Calculate the throughput time for the entire system.
c)
What is the daily production rate for the system if the line operates for 9 hours a
day?
Question 3:
S7.15 A production process at Kenneth Day Manufacturing is shown in the figure below.
The drilling operation occurs separately from and simultaneously with the sawing and
sanding which are independent sequential operations. A product needs to go through
only one of the three assembly operations (the operations are in parallel).
a)
Which operation is the bottleneck?
b)
What is the bottleneck time?
c)
What is the throughout time of the overall system?
d)
If firm operates 10 hours per day, 20 days per month, what is the monthly
capacity of the manufacturing process?
