Owners of a local restaurant are concerned about their ability to provide quality service as they continue to grow and attract more customers. They have collected data from Friday and Saturday nights, their busiest times of the week. During these time periods about 75 customers arrive per hour for service. Given the number of tables and chairs, and the typical time it takes to serve a customer, the owners estimate they can serve on average about 100 customers per hour. During these nights, are they in the zone of service, the critical zone, or the zone of nonservice?

- HDFC Bank has a single automated teller machine (ATM) located in a shopping center. Data were collected during a period of peak usage on Saturday afternoon and it was found that the average time between customers arrivals is 3.6minutes with a standard deviation of 0.7minute.lt also was found it takes an average of 2.8minutes (with a standard deviation of 1.9minutes) for a customer to complete a transaction. (a) Calculate expected customer arrival rate & service rate per server? (b) Calculate the expected server utilization? (c) Approximately how long will customers need to wait in line during the peak usage period?. 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…Gilman Heating and Air Conditioning Gilman Heating and Air Conditioning Inc. provides a broad range of services to commercial and residential customers, including installation and repair of several different brands of heating and air-conditioning systems, Gilman has a fleet of 28 trucks, each operated by one or more service technicians, depending on the size of a job. A recurrent problem for Gilman has been coordinating the service teams during the day to determine the status of a job and the need for parts not kept in the service vehicle, as well as to identify which team to send on emergency calls. Gilman's service area is spread over an urban/rural area of approximately 50 square miles. The company has developed cost and price sheets so that the service technicians accurately and consistently price the service work they perform.
- Tema Tire Services (TTS) decided to hire a new mechanic to handle all tire changes for customers ordering a new set of tires. Two mechanics have been shortlisted for the job.

The other mechanic has several years of experience, can service an average of four customers per hour, but must be paid GH¢20 per hour.

They have collected data from Friday and Saturday nights, their busiest time of the week. During these time periods, about 75 customers arrive per hour for service. Given the number of tables and chairs, and the typical time it takes to serve a customer, they figure they can serve, on average, about 100 customers per hour. The owners now anticipate that in one year, their demand will double from the current demand of 75 arrivals per hour, as long as they can provide good service to their customers. How much will they have to increase their service capacity to stay out of the critical zone? That is, how many customers should they be able to plan for?
