Question

PA 3-11 The local driver's license center processes... The local driver's license center processes applications for driver's license renewals through the following three steps. First, the customer registers with one of 1 receptionist(s), who updates the customer's information in the database. This first step takes 3 minutes per customer. Then the customer visits one of 3 cashiers to pay the associated fees for the license renewal. This takes 10 minutes per customer because several forms must be printed from the computer and signed by the customer. Finally, the customer visits one of 3 license processing stations where the customer's picture is taken and the license is printed. This final step takes 6 minutes per customer. Assuming unlimited demand, what is the flow rate of the process a. per hour in customers per hour? (Round to nearest integer) Assuming unlimited demand, what would the new flow rate be if to nearest integer) b. the center added one server to the bottleneck resource? (Round per hour

Explanation / Answer

(a) Flow rate of the process = 18 customers per hour (b) Flow rate of the process = 20 customers per hour Workings: (a) As per data updation: Time required for updating customer information in data base = 3 minutes per customer Number of customers per hour = 60 minutes / 3 minutes per customer = 20 customers per hour As per Payment structure: Time required for payment process = 10 minutes per customer Number of customers per hour = 60 minutes / 10 minutes per customer 6 customers Number of cashier = 3 Therefore, total flow rate = 6 customer X 3 cashier = 18 customers per hour As per Final step, taking picture and printing license: Time required for taking picture and printing license = 6 minutes per customer Number of customers per hour = 60 minutes / 6 minutes per customer 10 customers Number of cashier = 3 Therefore, total flow rate = 10 customer X 3 cashier = 30 customers per hour Here, the lowest process flow rate is 18 customers per hour as per payment method which is consider to be the bottleneck of the process. Therefore processflow is 18 customers per hour. (b) Here the number of cashier increase from 3 to 4. As per data updation: Time required for updating customer information in data base = 3 minutes per customer Number of customers per hour = 60 minutes / 3 minutes per customer = 20 customers per hour As per Payment structure: Time required for payment process = 10 minutes per customer Number of customers per hour = 60 minutes / 10 minutes per customer 6 customers Number of cashier = 4 Therefore, total flow rate = 6 customer X 4 cashier = 24 customers per hour As per Final step, taking picture and printing license: Time required for taking picture and printing license = 6 minutes per customer Number of customers per hour = 60 minutes / 6 minutes per customer 10 customers Number of cashier = 4 Therefore, total flow rate = 10 customer X4 cashier = 40 customers per hour Here, the lowest process flow rate is 20 customers per hour as per data updation which is consider to be the bottleneck of the process. Therefore processflow is 20 customers per hour.
