From 5 a.m. to 6 a.m., four callers contact a help desk. The callers spend 2, 5, 3,and 10 minutes on their calls. What is the average flow time of a caller at this help desk?
Consider a bank branch that has three distinct customer arrival patterns
throughout the day, as measured by average arrival rates (below).
Morning (8:30 - 11:30):
arrival 1 = 47 per hour.
%3D
Lunch (11:30 - 1:30):
arrival 2 = 70 per hour.
Afternoon (1:30 - 4:00):
arrival 3 = 30 per hour.
Regardless of the time of day, the average time it takes for a teller to serve
customers is 3.17 minutes.
Because of competition with other banks in the area, management has
developed an internal goal to keep the average customer wait before service to
be less than 4 minutes. With that in mind, answer the following:
a. During the morning period, what is the minimum number of tellers that
the bank needs to hire to achieve the 4-minute service goal mentioned
above? [ Select]
b. During lunch, what is the minimum number of tellers that the bank needs
to hire to achieve the 4 minute service goal mentioned above?
[ Select ]
c. In the afternoon, what is the minimum number of tellers that the bank

- Bayside General Hospital is trying to streamline its operations. A problem-solving group consisting of a nurse, a technician, a doctor, an administrator, and a patient is examining outpatient procedures in an effort to speed up the process and make it more cost-effective. Listed here are the steps that a typical patient follows for diagnostic imaging: Patient enters main hospital entrance Patient takes a number and waits to be called to registration desk Patient registers Patient is taken to diagnostic imaging department Patient registers at diagnostic imaging reception Patient sits in department waiting area until dressing area clears Patient changes in dressing area Patient waits in dressing area Patient is taken to exam room Exam is performed Patient is taken to dressing area Patient dresses Patient leaves Create a service blueprint of the procedure and identify opportunities for improvement.

If the bed turnaround time is excessive, it can cause problems with patient flow and delay medical procedures throughout the hospital. This can cause long waiting times for physicians and patients thus creating customer dissatisfaction. The admissions RN has assigned a patient care associate to measure the bed turnaround time for a randomly selected bed each morning., afternoon, and evening for 30 days. Following are the bed turnaround time sample observations: Day Day Bed Turnaround Times (min) 1 1 127 135 167 144 151 2 2 140 155 122 135 119 3 3 112 128 97 118 131 4 4 223 135 154 187 150 5 5 181 155 160 172 166 6 6 103 158 145 124 149 7 7 146 135 167 150 178 8 8 104 122 115 137 129 9 9 136 158 137 148 156 10 10 145 163 106 139 170 11 11 84 146 125 98…arrow_forwardCustomers send emails to a help desk that has three employees who answer theemails (and this is their only responsibility).

- The store opens at 8 am. Customers will arrive at Poisson rate λ = 10 per hour. (i) At what time do you expect the first customer to arrive? (ii) Given that the second customer arrived after 8.10 am, what is the expected arrival time of the first customer? (iii) After serving the third customer, the sales clerk takes a 10-minute break at 8.20 am. Upon his/return, he finds that the fourth customer has arrived. What is the probability that the customer has been waiting for more than 3 minutes?arrow_forwardA lab provides ultrasound service to patients. The service process consists of two steps: 1. Registration. Performed by a receptionist (Salary rate = $25/hr; Process time = 6 minutes/patient) 2. Ultrasound scan. Performed by a technician (Salary rate = $30/hr; Process time = 20 minutes/patient) Note that the ultrasound images need to be read by radiologists, but we assume that they have an ample capacity and thus will not model the role in the service process. Currently, the lab has 2 receptionists and 3 technicians. The manager anticipates demand to grow to 14 patients/hr in the near future. Thus, he plans to hire more receptionists and/or technicians to increase the service capacity to at least 14 patients/hr. What would be the extra payroll cost (in dollars per hr)?arrow_forwardSuppose a coffee shop order and fulfillment process is configured simply as a single queue with two steps: wait and service. Customers enter, wait their turn, and then are served, by placing and receiving their order all at once. Suppose that an average of 10 customers per hour enter the coffee shop while the shop is open. On average, there are two customers waiting in line to place their orders. It takes an average of 2 minutes to go through the service step, that is, it takes 2 minutes to complete the second step of placing and receiving the order. In steady state, O The average wait time before placing an order is 12 minutes. O The average time between customer arrivals is 5 minutes. O None of the answers are correct. There is an average of one customer being served at a time. O The average total time to wait and be served is 15 minutes.arrow_forward

Fruit loaders receive about $12 per hour. Truck drivers waiting in the queue or at the loading gate are drawing a salary but are productively idle and unable to generate revenue during that time. What would be the hourly cost savings to the firm associated with employing two loaders instead of one? Not this: 12-19 Juhn and Sons Wholesale Fruit Distributors employs one worker whose job is to load fruit on outgoing company trucks. Trucks arrive at the loading gate at an average of 24 per day, or 3 per hour, according to a Poisson distribution. The worker loads them at a rate of 4 per hour, following approximately the exponential distribution in service times. Not this: 2-20 Juhn believes that adding a second fruit loader will substantially improve the firm’s efficiency.
