Joan has a small design and tailoring shop making custom outfits for women. She has two employees. Each employee only begins working on a dress when a customer order has
been received and then she makes the dress from beginning to end. The average production time of a dress is 1.8 days, with a standard deviation of 2.1 days. Historically, Joan has
been receiving orders with interarrival times of one day on average. The interarrival times of orders have a coefficient of variation of one.
(Carry at least 4 decimal places in all intermediate calculations. Round your final answer to 2 decimal places.)
What is the expected waiting time, in days, between when an order is received and when production begins on the dress?
A. 9.12 days B. 6.50 days C. 1.23 days D.3.41 days
12-13 Mike Dreskin manages a large Los Angeles movie theater complex called Cinema I, II, III, and IV. Each of the four auditoriums plays a different film; the schedule is set so that starting times are staggered to avoid the large crowds that would occur if all four movies started at the same time. The theater has a single ticket booth and a cashier who can maintain an average service rate of 280 movie patrons per hour. Service times are assumed to follow an exponential distribution. Arrivals on a typically active day are Poisson distributed and average 210 per hour.
To determine the efficiency of the current ticket operation, Mike wishes to examine several queue operating characteristics.
a. Find the average number of moviegoers waiting in line to purchase a ticket.
b. What percentage of the time is the cashier busy?
c. What is the average time that a customer spends in the system?
d. What is the average time spent waiting in line to get to the ticket window?
e. What is the…
The 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…

- The 4M company has a lathe as the centerpiece of the plant's work. The jobs arrive according to a Poisson process with an average rate of 2 per day. The processing time of each job is exponentially distributed with an average of 1/ 4 day. Since the jobs are large, if they are not in process they are stored in a warehouse some distance from the machine. However, to save time in bringing them in, the production manager proposes to add space for 3 in-process jobs in addition to the one on the lathe (the rest will continue to be stored). With this proposal, what proportion of the time will the space next to the lathe be adequate for the waiting jobs? Calculate your answer using the formulas available.arrow_forwardBeate Klingenberg manages a Poughkeepsie, New York, movie theater complex called Cinema 8.

Arrivals on a normally active day are Poisson distributed and average 180 per hour.

The airport has three screening stations available, and the facility manager must decide how many to have open at any particular time.

- The College Avenue Sub Shop is located in a small college town. Virtually all of its phone delivery orders are in the evening, between 5:00 P.M. and 1:00 A.M., so the shop has a delivery person for that time period. It receives an average of about 3 orders per hour (Poisson distributed). However, because of the different distances the delivery person must travel, the service time is undefined, with a mean of 15 minutes and a standard deviation of 6 minutes. Compute L, Lq, W, and Wq.arrow_forwardAt Trojans Urgent Care Clinic, there is one triage nurse, 5 nurse practitioners, and 3 doctors. Patients arrive to the triage nurse, and the triage nurse decides if their case can be handled by a nurse practitioner or must be handled by a doctor. The triage nurse can detect patients whose case can be handled by a nurse practitioner in on average 5 minutes with standard deviation 1 minute; however, the triage nurse spends on average 10 minutes with standard deviation 3 minutes with patients whose case is eventually handled by a doctor. Patients seeing a nurse practitioner spend on average 30 minutes with standard deviation 8 minutes with the nurse practitioner, and patients seeing a doctor spend on average 45 minutes with standard deviation 10 minutes with the doctor. 60% of arriving patients are cared for by a nurse practitioner and 40% of arriving patients are cared for by a doctor. Patients leave the Urgent Care Clinic after seeing either the nurse practitioner or the doctor. a) If 8…arrow_forwardDuring an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.arrow_forward
- The medical director of a large emergency clinic faces a problem of providing treatment for patients who arrive at different rates during the day. There are several doctors available to treat patients when needed. If not needed, they can be assigned to other responsibilities (for example, lab tests, reports, x-ray diagnoses) or else rescheduled to work at other hours. It is important to provide quick and responsive treatment, and the medical director feels that, on the average, patients should not have to sit in the waiting area for more than 20 minutes before being seen by a doctor. Patients are treated on a first-come, first-served basis and see the first available doctor after waiting in the queue.
