Process Step Number of Workers Time per Customer (in Minutes) 1 6 1 2 3 6 18 14 4 5 4 3 Assuming that the process starts out empty and is worker-paced, how long will it take (in minutes) to serve 21 customers? (Round to nearest minute.) minutes to serve 21 customers PA 3-11 (Algo) An automated car wash serves customers... An automated car wash serves customers with the following serial process: pretreat, wash, rinse, wax, hand dry. Each of these steps is performed by a dedicated machine except for the hand-dry step, which is performed manually on each car by one of three workers. The steps of the process have the following processing times: Pretreat: 2 minute per car Wash: 4 minutes per car Rinse: 3 minutes per car Wax: 3 minutes per car Hand dry: 8 minutes per car ences Round "Flow rate" and "Utilization of hand dry" and "Cycle time to 2 decimal places a.

Starting from an empty system (and assuming the stations can work independently), how long would it take (minutes) to wash 8 cars? f. minutes PA 3-12 (Algo) 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 the receptionist, who updates the customer's information in the database. This first step takes 2 minutes per customer. Then, the customer visits one of 2 cashiers to pay the associated fees for the license renewal. This takes 4 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 12 minutes per customer. a. Assuming unlimited demand, what is the flow rate of the process in customers per hour? (Round to nearest Integer.) nces 15 per hour b. If demand is 8 customers per hour, what is the utilization of the receptionist? (Round to nearest integer.) 27 percent c.
