Chapter F, Problem 18P

Question:

• • • F.15 Connecticut Tanning has two tanning beds. One bed serves the company’s regular members exclusively. The second bed serves strictly walk-in customers (those without appointments) on a first-come, first-served basis. Orv karan, the store manager, has noticed on several occasions during the busy 5 hours of the day (2:00 p.m. until 7:00 p.m.) that potential walk-in customers will most often walk away from the store if they see one person already waiting for the second bed. He wonders if capturing this lost demand would justify adding a third bed. Leasing and maintaining a tanning bed costs Connecticut Tanning $600 per month. The price paid per customer varies according to the time in the bed, but Orv has calculated the average net income for every 10 minutes of tanning time to be $2. A study of the pattern of arrivals during the busy hours and the time spent tanning has revealed the following:

  1. a. Simulate 4 hours of operation (arrivals over 4 hours). Use the 14th column of Table F.4 (p. 785) for arrival times and the 8th column for tanning times. Assume there is one person who has just entered the bed at 2:00 p.m. for a 20-minute tan. Indicate which customers balk at waiting for the bed to become available. How many customers were lost over the 4 hours?
  2. b. If the store is open an average of 24 days a month, will capturing all lost sales justify adding a new tanning bed?

QUESTION 1 A multiple channel queuing system with a Poisson arrival rate, and an exponential service time distribution has an average arrival rate of 2.5 customers per hour and an average service time of eighty minutes per customer. A queuing system is described as unstable or overloaded if its utilization rate is greater than, or equal to one. For the system just described, what is the minimum number of servers required to retain stability i.e., to avoid overloading? A. 3 B. 2 C. 4 D. 1 QUESTION 2 Customers arrive at the lone check-out desk of a certain convenience store at the average rate of 0.23 per minute.

QUESTION 5 Regional Airlines is establishing a new telephone system for handling flight reservations. During the 10:00 AM to 2:00 PM time period, calls to the reservation agent occur randomly at an average rate of one call every 3.75 minutes. Historical service time data show that a reservation agent spends an average of 3 minutes with each customer. The waiting line model assumptions of Poisson arrivals and exponential service times appear reasonable for the telephone reservation system. At a planning meeting, Regional's management team agreed that an acceptable customer service goal is to answer at least 75% of the incoming calls immediately. During the planning meeting, Regional's vice president of administration pointed out that the data show that the average service rate for an agent is faster than the average arrival rate of the telephone calls. The vice president's conclusion was that personnel costs could be minimized by using one agent and that single agent must be able to…
