Question

A diagram of a face-to-face service process is given below. There are four workstations (called "operations"), each performing a different task with a single server at each. The expected demand is λ.-25 units per hour. Clerk B Clerk C Clek D w仍 OPI 40 cistomers bour bout 5. Determine the process times (in seconds per unit) for each of the activities. (2 pts)

Answer 1

5.

Answer:

The process time in seconds per unit at CP 1 is 72 seconds per activity.

Because,

1 hour = 60 minutes = 3600 seconds

Therefore, 3600 seconds ÷ 50 customers/activities is equal to 72 seconds per activity.

Similarly, the process time in seconds per unit at CP 2 is equal to 3600 ÷ 30 customers/units = 120 seconds per activity.

Similarly, the process time in seconds per unit at CP 3 is equal to 3600 ÷ 40 customers/units = 90 seconds per activity.

Similarly, the process time in seconds per unit at CP 4 is equal to 3600÷ 4 customers/units = 90 seconds per activity.

6.

Answer:

CP 2 at Clerk B is the bottleneck stage among the four workstations as it's serving 30 customers per hour only as opposed to its capacity of 40 customers per hour.

7.

Answer: (c). 40 units per hour would be the throughout units of the process.
