Question 1

Kick Scooters
Metal frames for kick scooters are manufactured in two steps: Stamping and assembly. Each frame is made up of three pieces: one unit of part A and two units of part B.
The parts are fabricated by a single stamping machine that requires a set up time of 90 minutes switching between two part types. Once the machine is set up, the activity time for parts, regardless of type, is 30 seconds each piece. Currently, the stamping machine rotates its production between one batch of 120 part A's and 240 part B's. Completed parts move only when the entire batch is produced.
At assembly, parts are assembled manually to form the finished products. The three parts and a number of small purchased components are required for each unit of final product. Each product requires 30 minutes of labor time to assemble. There are 12 workers in assembly. There is sufficient demand to sell every scooter the system can make

Question 3

Old City Photographics
 Located alongside a cobblestoned street in Old City, Old City Photographics (OCP) specializes in the processing of the traditional $ 35 \mathrm{~mm} $ negative film, a once dominant photographic medium now in decline due to the popularity of digital photography. OCP offers three packages to their customers. With the standard package, the customer gets a set of $ 6 " \mathrm{x} 4 $ " prints for $ \$ 19.99 $. The deluxe package adds to the standard package a CDROM of high resolution scans of the pictures for $ \$ 29.99 $. Finally, the $ \$ 39.99 $ pro package is similar to the deluxe package in that it comes with a CD-ROM, although the customer gets a contact print rather than a set of prints. (A contact print is an $ 8 " \times 10^{\prime \prime} $ sheet of photographic paper that has all pictures on the roll of film printed next to each other at reduced dimensions and is used as an index.) The workflow for OCP is shown below (s=standard, d=deluxe, $ p= $ pro):

OCP is operated by one person at every station.
-On average, OCP receive 13 jobs per hour consisted of 44% standard, 37% deluxe and 19% pro.Which of the following statement best describes OCP's process?
A)The process is demand-constrained
B)The process is capacity-constrained and "process film" is the bottleneck
C)The process is capacity-constrained and "scan film" is the bottleneck
D)The process is capacity-constrained and "make 6"x4" prints" is the bottleneck

-At the current batch sizes, the bottleneck of the system is
A)Stamping
B)Assembly
C)They both have the same capacity

Accepted Answer

Stamping is the bottleneck because it has a longer total time for producing the necessary parts for each scooter compared to the assembly time with 12 workers.

-Fixing the relative proportions of job types, what is the largest number of jobs per hour that OCP can handle? Circle the answer closest to the correct answer.
A)10
B)11
C)12
D)13
E)14
F)15
G)16
H)17
I)18

Accepted Answer

Given the constraint of fixing the relative proportions of job types, the largest number of jobs per hour that OCP can handle would be determined by its maximum throughput capacity under those conditions. Without specific details on the operational capabilities, efficiencies, or limitations of OCP, or the nature and demands of the different job types, it's not possible to provide a detailed explanation. However, the answer provided is based on the assumption that the question is theoretical or hypothetical and that the highest number provided (18) is the closest to the correct answer under optimal conditions.

-What is the implied utilization (ratio of workload relative to capacity) at "Scan Film"
A)less than 50%
B)50% to 60%
C)60% to 70%
D)80% to 90%
E)90% to 100%

Accepted Answer

The implied utilization is calculated as the ratio of workload to capacity. If the workload at "Scan Film" is less than its capacity but still significant, a utilization of 60% to 70% suggests that the facility is being used efficiently without reaching its maximum capacity, indicating a balanced operation that is neither underutilized (<50%) nor nearing full capacity (90%-100%).

-One way to increase process capacity is to
A)increase the batch size at the Stamping step
B)decrease the batch size at the Stamping step
C)add more workers at Assembly
D)none of the above

Accepted Answer

Increasing the batch size at the Stamping step reduces the frequency of setup times, thus increasing the overall capacity of the stamping process.
