Question 8

A service process has three stages: Stage A, Stage B, and Stage C. Stage A has a capacity of 20 units per hour, Stage B has a capacity of 15 units per hour, and Stage C has a capacity of 25 units per hour. Which stage is the bottleneck, and what is the maximum throughput of the entire process in units per hour?

Accepted Answer

Stage B is the bottleneck, and the maximum throughput is 15 units per hour.

Question 9

A service operation has a process with a theoretical cycle time of 5 minutes per unit. However, due to various inefficiencies, the actual average cycle time is 8 minutes per unit. What is the process efficiency, expressed as a percentage?

Question 13

A call center receives an average of 500 calls per day. The average handling time per call is 6 minutes. If the call center employs 50 agents, each working an 8-hour shift, what is the utilization rate of the agents, expressed as a percentage?

Accepted Answer

25%

Question 14

A call center aims to maintain a service level where 80% of calls are answered within 20 seconds. If the average call arrival rate is 6 calls per minute, and the average service time is 3 minutes, calculate the minimum number of agents needed to meet this service level. Assume an M/M/c queueing model and provide the formula used for your calculation.

Accepted Answer

The calculation requires complex queueing formulas (e.g., Erlang C) to determine the number of agents. The Erlang C formula calculates the probability of delay. The number of agents must be iteratively adjusted until the probability of delay is low enough to meet the 80% service level within 20 seconds. Due to the complexity, a direct numerical answer without specific queueing software or tables is not feasible here.

Question 15

A hospital emergency room has a single triage nurse who assesses patients as they arrive. The arrival rate of patients is 4 per hour, and the triage nurse spends an average of 10 minutes with each patient. What is the utilization rate of the triage nurse?

Question 19

A small coffee shop experiences a surge in customers every morning between 7 AM and 9 AM. The average arrival rate during this peak period is 100 customers per hour. The shop can serve an average of 1.5 customers per minute. Calculate the average number of customers in the system (L) during the peak period, assuming an M/M/1 queueing model.

Accepted Answer

First, convert the arrival rate to customers per minute: $\lambda = \frac{100}{60} \approx 1.67$ customers per minute. The service rate is $\mu = 1.5$ customers per minute. Since $\lambda > \mu$, the queue will grow indefinitely, and the M/M/1 model is not stable. However, if we assume $\mu = 2$ customers per minute, then $L = \frac{\lambda}{\mu - \lambda} = \frac{1.67}{2 - 1.67} = \frac{1.67}{0.33} \approx 5.06$ customers.

Question 20

A service company is using the DMAIC cycle to improve its customer service process. After the 'Measure' phase, the team identifies that the average customer wait time is 15 minutes, with a standard deviation of 3 minutes. During the 'Analyze' phase, they determine that 80% of the wait time is due to a bottleneck in the order processing department. If they reduce the order processing time by 50%, what would be the expected reduction in the average customer wait time?

Accepted Answer

B. 6 minutes

Answer

A. 3 minutes

Answer

C. 7.5 minutes

Answer

D. 12 minutes
