The manager of a car wash must decide whether to have one or two wash lines. One line will mean a fixed cost of $6,000 a month, and two lines will mean a fixed cost of $10,500 a month. Each line would be able to process 15 cars an hour. Variable costs will be $3 per car, and revenue will be $5.95 per car. The manager projects an average demand of between 14 and 18 cars anhour. Would you recommend one or two lines? The car wash is open 300 hours a month.

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 106 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 162 customers per hour. Use Exhibit 4.6. Furthermore, the owners anticipate that in one year their demand will double as long as they can provide good service to their customers. a. Currently, during these nights, are they in the zone of service, the critical zone, or the zone of nonservice? EXIBIT IS THE PICTURE ADDED
O Critical zone
O Zone of service
O Zone of nonservice
b. Next year, after demand doubles, what must the service capacity increase to (at minimum) to stay out of the critical zone?Note:…

- A call center has been serving 900 customers per day, with a 10% capacity cushion. There have been complaints about the length of time customers have to wait before their call is answered. If the manager of the call center wants to double the capacity cushion, how much extra capacity is needed?arrow_forwardConsider the order delivery system of Heartha Hardware and Construction Supplies:- Customers (whether by bulk or retail) would line up in a counter where sales representatives will entertain them. It would take about 15 minutes before a customer will be entertained due to the number of customers being served by the sales representative and only about 4 sales representatives are on duty every day.- The sales representative will take down the customer’s order in the order slip with corresponding prices. On some cases, she will ask the person in-charge in the warehouse if the items are available. She then forwards the order slip to the cashier.- The cashier would sum-up again manually the order slip from the sales representative to check the accuracy of the footing of the totals as well as the prices indicated.

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?arrow_forwardOwners of a local restaurant are concerned about their ability to provide quality service as they continue to grow and attract more customers.

Calculate the probability of zero patients in the system (P0), probability of one patient (P1), and probability of two or more patients simultaneously arriving during the night shift. 3.

The laundromat is considering a new repair service that guarantees repairs in0.50 day, but they charge $10 more per hour than thecurrent repair service. Should the laundromat switch tothe new repair service?arrow_forwardMary Smith, manager of the ABC Hotel, is considering how to restructure the front desk to reach an optimum level of staff efficiency (the utilization factor between 80% and 95% will be considered acceptable) and guest service expressed as an average waiting time in the line/queue (any plan resulting in the waiting time longer than 20 minutes is unacceptable). At present, the hotel has four clerks on duty, each with a separate waiting line, during the peak check-in time. Observation of arrivals during this time shows that an average of 60 guests arrive each hour(15 guests on average for each check-in line) and they follow a Poisson process. It takes an average of 3 minutes and 20 seconds for each front-desk clerk to register each guest (this and all other service times are exponentially distributed). Mary is considering a number of plans for improving guest service by reducing the length of time guests spend waiting in line. The first plan is to convert the current system into a…arrow_forward
