Summary Introduction
To determine: The thing that would occur for the given situation.
Expert Solution & Answer
Explanation of Solution
Given information:
It is given that a summer camp offer one-week programs. However, it faces a challenge with long queues on each Saturday morning when the parents try to check-in their children. They have the plan of adding more staff to assist the check-in process.
Determine the thing that would occur for the given situation:
Adding more staff to assist the check-in process will decrease the average waiting time of the parents, decrease the maximum waiting time, and the average waiting time of the parent who are waiting to check-in their child will also be reduced.
Hence, option (g) is correct and options (a), (b), (c), (d), (e), and (f) are incorrect.

A summer camp that offers one-week programs faces the challenges of long queues asparents try to check in their children each Saturday morning. If they were to add morestaff to assist with the check-in process, then which of the following will occur?i. The average time parents wait decreases.ii. The maximum time the parents wait decreases.iii. The average number of parents waiting to check in their child decreases. a. Just Ib. Just IIc. Just IIId. I and IIe. I and IIIf. II and IIIg. I, II, and III
What effect will decreasing the variability of the service rate have on the performance of
the queuing system (all else being the same)?
reduce customer average waiting time in the system
cannot be determined without additional information
while more customers, they arrive at separate times & create a shorter queue
the queue moves faster thanks to a faster arrival rate

In an M/MA queueing system, the arrival rate is 3 customers per hour and the service rate is 5 customers per hour. If the service
process is automated (resulting in no variation in service times but the same service rate), what will be the resulting performance
measurements? (Round your answers to 3 decimal places.)
a. What is the utilization?
Utilization
b. What is the expected number of customers in the system (L)?

Single-Queue, Multiple-Channel System Structure (Fig 5.8 in text) Multiple-Queue, Multiple-Channel System Structure (Fig 5.9 in text) 9. An easy way to understand Queuing Model formulas is to understand that L refers to Number of items while W refers to time. q refers to the queue and s refers to the system. So Lq refers to the number of units in the queue (waiting line). Ls refers to the number of items in the system (queue and service). Write out the formulas for the following: a. Average Wait time in the Queue b. Average Wait time in the System c. Average number of units in the Queue d. Average number of units in the System e. System utilization f.

Each patient comes in to her office on average of every 27 minutes, and she spends an average of 19 minutes with each one of them. Assume that both patient inter-arrival times and the times that she spends with the patient are exponentially distributed. Keep in mind of the system including the psychologist and the patients come to her for help, who when necessary, waiting in line for their turn. 1.
