Question
Chapter 18, Problem 2CTE
a)
Summary Introduction
To determine: Reasons doubling the service rate of single-server system would cut the average waiting time in line in half.
Introduction: A waiting line system, otherwise called a queuing or lining system. It is one of the most seasoned and most generally utilized quantitative investigation systems. Waiting lines are an ordinary event, influencing individuals looking for foodstuffs, purchasing fuel, influencing a bank to store, or looking out for the phone for the most readily accessible carrier reservationist to reply.
b)
Summary Introduction
To determine: Impact on the average number waiting in line.
c)
Summary Introduction
To determine: Managerial implications on the analysis.

Please show a corrct solution and answer. Thank you.
A single server queuing system has an average service time of 10 minutes per customer, which is exponentially distributed. The manager is thinking of converting to a system with a constant service time of 10 minutes. The average arrival rate will remain the same. The effect will be to:
Select one:
a.
increase utilization.
b.
decrease utilization.
c.
not have any effect since the service time is unchanged.
d.
increase the average waiting time.
e.
decrease the average waiting time.

- Consider a bank branch that has three distinct customer arrival patterns throughout the day, as measured by average arrival rates (below). Morning (8:30 - 11:30): arrival 1 = 47 per hour. %3D Lunch (11:30 - 1:30): arrival 2 = 70 per hour. Afternoon (1:30 - 4:00): arrival 3 = 30 per hour. Regardless of the time of day, the average time it takes for a teller to serve customers is 3.17 minutes. Because of competition with other banks in the area, management has developed an internal goal to keep the average customer wait before service to be less than 4 minutes. With that in mind, answer the following: a. During the morning period, what is the minimum number of tellers that the bank needs to hire to achieve the 4-minute service goal mentioned above?
