Question 5

​How can a system be changed to improve the service rate?

Accepted Answer

Question 6

In developing the total cost for a waiting line, waiting cost takes into consideration both the time spent waiting in line and the time spent being served.

Accepted Answer

A) True 
 B)False

Question 7

Two new checkout scanning systems are under consideration by a retail store. Arrivals to the checkout stand follow the Poisson distribution with λ = 2 per minute. The cost for waiting is $18 per hour. The first system has an exponential service rate of 5 per minute and costs $10 per hour to operate. The second system has an exponential service rate of 8 per minute and costs $20 per hour to operate. Which system should be chosen?

Accepted Answer

First system costs .

Question 8

Waiting line models describe the transient-period operating characteristics of a waiting line.

Accepted Answer

A) True 
 B)False

For a single-server queuing system, the average number of customers in the waiting line is one less than the average number in the system.

Diagram the servers and arrivals in the single and multiple channel models. Designate the line and the system.

Give examples of systems you have seen in which a) blocked arrivals are cleared, and b) there is a finite calling population.

Operating characteristics formulas for the single-channel queue do NOT require

How can a system be changed to improve the service rate?

In developing the total cost for a waiting line, waiting cost takes into consideration both the time spent waiting in line and the time spent being served.

Waiting line models describe the transient-period operating characteristics of a waiting line.
