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?

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 number of tables and chairs, and the typical time it takes to serve a customer, they the owners estimate they can serve on average about 100 customers per hour. Owners of the restaurant anticipates that, in one year their demand will double as long as they can provide good service to their customers. How much will they have to increase their service capacity to in order to stay out of the critical zone? (Roundup your answer to the next whole number.)
The management of a drinking water refill station is planning to estimate the average cost of paying technicians to maintain the water refill stations. The management wants their OM to provide normal times and standard times for cleaning a station based on observed values, rating factors (RF), and a 20% allowance.
The manager of a local restaurant “RRR” asks you to improve the existing “online food ordering system” with an additional function. It is desired that the new function informs the customer about the approximate time needed to deliver the foods after customer submits the order via the website of “RRR”. If you plan to prepare an online questionnaire for the customers that they may fill on theweb site of “RRR” Write 2 questions that you may use nominal scale and 2 questions that you may useinterval scale.
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. One mechanic has limited experience, can be hired for GH¢14 per hour, and can service an average of three customers per hour. 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. Historical data shows that customers arrive at the TTS garage at the rate of two customers per hour. b) If the company assigns a customer waiting cost of GH¢30 per hour, which mechanic provides the lower operating total cost (TC)? c) With the aid of a sketch, show the economic relationship between service cost and waiting costs, and justify whether or not it is necessary for TTS to keep investing in better and/or additional mechanics until waiting time reduces to ze
The sales manager of STC Telecommunication Company, conducts interviews of the sales representatives. During the interview, these questions were asked from the sales representatives which are related to the performance of their job: the percentage of the time spent in making presentations to new potential customers, telephone conversation with current customers, time spent working on the computer, and engaging in on- the job activities. What potential sources of error might be associated with the manager’s line of questioning specifically on the different tasks performed by the sales representatives?

Using the data on call volume in the accompanying table, how would you forecast short-term demand?
A local restaurant is 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 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? Keep in mind that service capacity utilization rate = arrivals rate / service rate.
