stand 56) One employee is in charge of the following activities at a refreshment ctivity Time per Customer seconds 5 seconds 5 minutes 0 seconds Activity reet customer Take order rocess order Print receipt emand rate is 20 customers per hour, what are the flow rate (in customers per hour), utilization, A) 20, 0.83, 0.05 If d and cycle time (in minutes per customer)? B) 24, 1, 0.04 D) 24, 1,2.5 C) 20, 0.83,3 57) Patients are arriving at a clinic at a rate of two per minute. Each patient's visit consists of four steps: check in, record vital signs, receive treatment, and check out. A receptionist takes 1 minute to check a patient in. A nurse takes 2 minutes to record the patient's vital signs. A doctor spends 10 minutes with a patient. A staff member takes 3 minutes to check a patient out. What is the cycle time of the process in minutes? A) 30 C) 20 B) 10 D) Cannot be determined 58) Students are going through a three-step process to obtain their ID cards. Each student will spend 2 minutes at the registration desk before going to one of three cashiers to pay a fee for the ID card. After that, he/she will visit one of four ID processing stations to have his/her picture taken and ID card printed. Visits to the cashier and ID processing station take 10 and 20 minutes respectively. If the demand rate is 0.125 student per minute, how long does it take to process 20 students the system is full? A) 152 minutes assuming B) 100 minutes C) 160 minutes D) 184 minutesExplanation / Answer
1.Processing time can be calulated as =( 5 + 25 + (1.5 × 60) + 30 )= 150 seconds.
Process capacity can be calculated as= 1/150 × 60 (seconds/minute) × 60 (minutes/hour) = 24 customers per hour.
Flow rate can be calculated as = Minimum(Demand, Process capacity) = Min(20, 24) = 20 customers per hour.
Utilization can be calulated as= Flow rate/Process capacity = 20/24 = 0.83.
Cycle time can be calculated as = 1/Flow rate = 1/20 × 60 (minutes/hour) = 3 minutes per customer
Therefore correct answer is (C ) 20,0.83,3
2.Activity of treatment by Doctor takes maximum time.Therefore it is the cycle time since it is bottleneck process. Thus cycle time of the process is 10 mins. Answer (B) 10 min is correct.
3.A student arrives at every=1/0.125= 8 min since demand rate is 0.125 student per minute
Time consumed to fill the system=8*3=24 min
Time consumed for processing 20 students =8*20=160 min
Therefore total time consumed is 184 mins. Therefore correct answer is (D) 184 min
