The Judy Gray Income Tax Service is analyzing its customer service operations during the month prior to the April filing deadline. On the basis of past data it has been estimated that customers arrive according to a Poisson process at a rate of 5 customers per hour. The time for Judy to complete a customer interview averages 10 minutes. (Actual resturns are completed by part-time interns hired by Judy.) Based on this information, answer the following questions: If you went to Judy, how much time would you allow for getting your return done? On average, how much room should be allowed for the waiting area? If Judy stayed in the offce 12 hours per day, how many hourg on average, per day, would she be busy? What is the probability that Judy is idle?

The task I am struggling with: Consider the baggage check-in of a small airline. Check-in data indicate that from 9 a.m. to 10 a.m. 255 passengers checked in. Moreover based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 35. How long did the average passenger have to wait in line? Thank you very much for your help.
. An automobile dealer is planning a new custom service center to repair the microcomputer-based engine controls in new-model cars. With the new diag- nostic equipment they are installing, each job should take about 75 minutes to complete. The dealer plans to operate the center 8 hours per day. Preliminary estimates suggest that about 5 customers will bring their cars for repair each day. To analyze this situation, make the following assumptions: The customer arrivals form a Poisson process. Each job requires on average 75 minutes. We can ignore the time that the service center is closed. (That is, no arrivals occur during such gaps, and we don't count them in the total response time.) (a) Measure time in hours. In the terms of queueing theory, what are A, μ, and p? (b) Compute an estimate of the average total response time (which we call Ts). 2 (c) Estimate the average number of cars in the center (including those waiting as well as in service). (d) Suppose the average number of…
On average, how much time would a server need to spend on a customer to achieve a service rate μ, with 30 customers per hour?
You are the manager of a local bank where three tellers pro-vide services to customers. On average, each teller takes 3minutes to serve a customer. Customers arrive, on average,at a rate of 50 per hour. Having recently received complaintsfrom some customers that they waited a long time beforebeing served, your boss asks you to evaluate the service sys-tem. Specifically, you must provide answers to the followingquestions:a. What is the average utilization of the three-teller servicesystem?b. What is the probability that no customers are being servedby a teller or are waiting in line?c. What is the average number of customers waiting in line?d. On average, how long does a customer wait in line beforebeing served?e. On average, how many customers would be at a teller’sstation and in line?
The BPD has three tellers to provide service. Each teller, on average, serves one customer in three minutes per customer, the latter arriving 50 every hour. Due to complaints received, an evaluation of the system has been requested:(a) Give the average utilization of the service system with the three tellers.b) What is the probability of arriving at the bank with no one there?c) What is the average number of customers waiting in line?d) On average how long does a customer wait in line to be served?e) On average how many customers would be served at a teller and waiting in line?
A crew of mechanics at the Highway Department garage repair vehicles that break down at an average of 3 vehicles every 12 minutes. The mechanic crew can service an average of 3 vehicles every 10 minutes with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $100 per hour. The cost associated with lost productivity from the breakdown is estimated at $50 per hour. Which is cheaper, the existing system with one service crew or a revised system with two service crews? Note that the average waiting time for adding the second crew is 0.02.
Hilltop Restaurant is located in Dempsey Hill. The restaurant has a capacity of 35 tables to serve customers. When doing its capacity planning and evaluating operational performance, the restaurant adopts the concept of “customer group” and uses it as unit of measurement to measure the workload in the service process. A customer group is a group of one or more people who arrive, get seated at a table, eat and depart. On average, a customer group takes 70 minutes to eat dinner, and then another 25 minutes to eat dessert. On average, a customer group generates a profit of $100 on dinner, and $30 on dessert. Now assume that Hilltop leases new space to open a “dessert bar” next door, and has opened up the wall between the two units to allow inside access from the restaurant to the dessert bar. The dessert bar can accommodate 15 tables. With this change, a customer group arrives and is seated at a table in Hilltop restaurant as usual. However, when the customer group finishes eating dinner,…

(a) Assume that all customer groups eat both dinner and dessert. Estimate the maximum number of customer groups per hour the restaurant can serve (capacity rate) by applying Little’s Law. At what rate (dollars per hour) is profit generated by the restaurant if it operates at capacity rate?
The Bijou Theater shows vintage movies. Customers arrive at the theater line at the rate of 100 per hour. The ticket seller averages 30 seconds per customer, which includes placing validation stamps on customers’ parking lot receipts and punching their frequent watcher cards. (Because of these added services, many customers don’t get in until after the feature has started.) What is the average customer time in the system? What would be the effect on customer time in the system of having a second ticket taker doing nothing but validations and card punching, thereby cutting the average service time to 20 seconds? Would system waiting time be less than you found in (b) if a second window was opened with each server doing all three tasks?

Pasquist Water Company (PWC) operates a 24-hour facil-ity designed to efficiently fill water-hauling tanker trucks.Trucks arrive randomly to the facility and wait in line to ac-cess a wellhead pump. Since trucks vary in size and the filling operation is manually performed by the truck driver, the timeto fill a truck is also random.a. If the manager of PWC uses the multiple-server modelto calculate the operating characteristics of the facility’swaiting line, list three assumptions she must make regard-ing the behavior of waiting trucks and the truck arrivalprocess.b. Suppose an average of 336 trucks arrive each day, thereare four wellhead pumps, and each pump can serve anaverage of four trucks per hour.▪ What is the probability that exactly 10 trucks will arrivebetween 1:00 p.m. and 2:00 p.m. on any given day?▪ How likely is it that once a truck is in position at a well-head, the filling time will be less than 15 minutes?c.
