Concept explainers
a)
To draw: A process flow diagram for this process.
a)
Explanation of Solution
Given information:
Process flow diagram:
b)
To determine: The capacity at the resource “Dentist”.
b)
Explanation of Solution
Given information:
Calculation of capacity:
Formula:
The capacity at “Dentist” is 20 patients.
c)
To determine: The bottleneck in the process.
c)
Explanation of Solution
Given information:
Determination of bottleneck:
The resource with the lowest capacity is the bottleneck. The resource “Dental assistant” has the lowest capacity of 12 patients per hour.
Hence, the bottleneck is Dental assistant.
d)
To determine: The flow rate.
d)
Explanation of Solution
Given information:
Determination of flow rate:
The bottleneck flow rate determines the flow rate of the process. Therefore, the flow rate of the dentist is:
The flow rate is 12 patients per hour.
e)
To determine: The utilization of resource “Receptionists”.
e)
Explanation of Solution
Given information:
Calculation of utilization:
The utilization is 50%.
f)
To determine: The cycle time of the process.
f)
Explanation of Solution
Given information:
Calculation of cycle time:
The demand is constrained and has a flow rate of
The cycle time is 125 minutes.
g)
To determine: The cycle time of the process.
g)
Explanation of Solution
Given information:
Calculation of cycle time:
The cycle time is 105 minutes.
h)
To determine: The time taken to serve 20 patients
h)
Explanation of Solution
Given information:
Calculation of time taken to serve 20 patients:
There are 3 resources and the cycle time is 5 minutes.

OPERATION MANAGEMENT
- The task I am struggling with: Consider the baggage check-in of a small airline. Check-in data indicate that from 9 a.m. to 10 a.m. 255 passengers checked in. Moreover based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 35. How long did the average passenger have to wait in line? Thank you very much for your help.arrow_forward5. Eat well is a small drive through fast food restaurant, staffed by an efficient employee John, is located in a super mall area. Customers arrive at the counter at an average of one every 15 minutes, and the customer arrival follows a Poisson distribution. John takes at most 10 minutes to process each food order. d) What percentage of time is John Idle?arrow_forwardA hospital Emergency Room currently registers each patient first through an initial check-in process, where s/he is seen by a doctor at the check-in, and then exits the process, either with a prescription or with admission to the hospital. Currently, 50 people per hour arrive at the Emergency Room, 10 percent of who are admitted to the hospital. On average, 35 registered patients are waiting to see a doctor at any time during this process. The registration process takes, on average, 6 minutes per patient. Among patients who receive prescriptions, average time spent with a doctor is 10 minutes. Among those admitted to the hospital, average time of stay is 30 minutes. Steps 1, 3, and 5 have zero duration (triggers or decision points). On average, how many patients are waiting to be registered or in the registation process (step 1)? On average, how long does a patient spend in the ER? On average, how many patients are there in the ER? Assume the process to be stable; that is,…arrow_forward
- 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. The average waiting time for each customer is 8 minutes. What is the average number of customers in the system (including waiting and using the service)? a 3 b 7 c 6 d 4arrow_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_forwardBayside 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 1.

The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times. What percentage of time is Judy idle? Note: Round your answer to 1 decimal place. How much time, on average, does a student spend waiting in line? Note: Do not round intermediate calculations. Round your answer to the nearest whole number. How long is the (waiting) line on average? Note: Round your answer to 2 decimal places. What is the probability that an arriving student (just before entering the Administrative Services Office) will find at least one other student waiting in line? Note: Do not round the intermediate calculations.

Guests can call housekeeping from 8:00 A.M.to midnight for any of their service needs. Housekeepingkeeps one person on duty during this time to respond to guest calls. Each room averages 0.7 call per day to house-keeping (Poisson distributed), and a guest request requires an average response time of 30 minutes (exponentially dis-tributed) from the staff person. 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_forward
