A campus deli serves 300 customers over its busy lunch period from 11:30 a.m. to 1:30p.m. A quick count of the number of customers waiting in line and being served by thesandwich makers shows that an average of 10 customers are in process at any point intime. What is the average amount of time that a customer spends in process?
The check-out area of a grocery store has the average customer interarrival time = 2 minutes, the average processing time of each cashier = 6 minutes, and in total 4 cashiers.

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,…

- 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. (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?arrow_forwardThe Delacroix Inn in Alexandria is a small, exclusive hotel with 20 rooms. Guests can call housekeeping from 8:00 A.M. to midnight for any of their service needs. Housekeeping keeps one person on duty during this time to respond to guest calls. Each room averages 0.7 call per day to housekeeping (Poisson distributed), and a guest request requires an average of 30 minutes (exponentially distributed) for the staff person to respond to and take care of. Determine the portion of time the staff person is busy and how long a guest must wait for his or her request to be addressed. Does the housekeeping system seem adequate?arrow_forwardConsider the baggage check-in process of a small airline. Check-in data indicate thatfrom 9 a.m. to 10 a.m., 240 passengers checked in. Moreover, based on counting thenumber of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 30. How long did the average passenger haveto wait in line?arrow_forward

Determine the portion of time the staff person is busy and how long a guest must wait for his or her request to be addressed. Does the house-keeping system seem adequate?arrow_forwardKitty Wonderland (KW) makes toys for cats. KW’s managers have recently learned that they can calculate the average waiting time for an order from the time an order is received and the time it is manufactured. They have asked for your help and have provided the following information. Expected number of orders for the product: 2,000 Manufacturing time per order: 4 hours Annual machine capacity in hours: 10,000 After learning about the average waiting time, KW’s managers are confused. They do not understand why, if annual machine capacity is greater than the average number of orders for the product, there would be any waiting time at all. Briefly answer the following questions Calculate the average waiting time per order. The managers have asked for your suggestions on what they can do to minimize or eliminate waiting time. How would you respond? Management is expecting sales to increase. Will average waiting time increase or decrease? Explain briefly.arrow_forwardThe time from when a patient is discharged from NorthShore Hospital to the time the discharged patient’s bed isready to be assigned to a new patient is referred to as thebed assignment turnaround time. If the bed turnaroundtime is excessive, it can cause problems with patient flowand delay medical procedures throughout the hospital. Thiscan cause long waiting times for physicians and patientsthus creating customer dissatisfaction. The admissions RNhas assigned a patient care associate to measure the bedturnaround time for a randomly selected bed each morning,afternoon, and evening for 30 days. Following are the bedturnaround time sample observations:a. Develop an x-chart to be used in conjunction with anR-chart using 3 limits to monitor the bed turnaroundtimes and indicate if the process is in control usingthese charts.b. Is the hospital capable of consistently achieving bedturnaround times of 120 minutes 15 minutes withoutimproving the process?arrow_forward
- During a typical Friday, the West End Donut Shop serves 2400 customers duringthe 10 hours it is open. A customer spends, on average, 5 minutes in the shop. On average,how many customers are in the shop simultaneously?arrow_forwardA Northwest Airlines ticket counter forecasts that 30 people per hour will need to check in. It takes an average of 1.5 minutes to service a customer. Assume that interarrival times and service times are exponential and that all customers wait in a single line for the first avaliable agent.If we want the average time a customer spends in line and in service to be 3 minutes or less, how many ticket agents should be on duty?arrow_forwardThe Cove is a midsized furniture store. Sales staff are assigned standard shifts (1st shift usually takes place between the hours of 9 a.m. and 5 p.m. 2nd shift is worked between 5 p.m. and 1 a.m. 3rd shift typically takes place between the hours of 12 a.m. and 8 a.m.), and the number of customers arriving per shift averages 40, Poisson distributed. A salesperson can deal with one customer in 5 minutes on average and costs the company $100 per shift in salaries and fringe benefits. Service times closely follow an exponential distribution. The manager is reviewing the number of salespersons to schedule for each shift. The cost of customers waiting before they receive service has been estimated at $2 per minute in terms of lost sales and loss of goodwill. a. If management wants to minimize the cost of both sales staff and customer wait times, how many salespersons should be working in each shift? b. What is the cost per shift to the company if they use the number of salespersons you…arrow_forward
- McBurger’s fast-food restaurant has a drive-through window with a single server who takes orders from an intercom and also is the cashier. The window operator is assisted by other employees who prepare the orders. Customers arrive at the ordering station prior to the drivethrough window every 4.5 minutes (Poisson distributed), and the service time is 2.8 minutes (exponentially distributed). Determine the average length of the waiting line and the waiting time. Discuss the quality of the service.arrow_forwardIf the restaurant runs a sale and the customer arrival rate increases by 20 percent how would this change the total time expected to serve a customer? How would this change the average number of cars in the drive-thru line?arrow_forwardA bank has 1 enquiries staff and six tellers. Customers enter the system and walk up to the enquires counter for the enquiries queue or they go to the tellers station where they join a single queue for the 6 tellers.The arrival rate at the enquiry counter, lambda 8 customers per hour and the service rate at the enquiry counter, Mu 6 minutes per customer. The arrival rate at the tellers’stations, lambda 10 clients per hour and the service rate at the tellerstations, Mu 4 minutes per client. Find the total time customers spend at the bankarrow_forward
