Question: New barcode readers will be purchased for use at cash registers in a supermarket. Management focuses on two brands. A brand barcode reader reads 10 packages per minute, while B brand barcode reader reads 15 packages per minute. Readers' one-day (1 day = 10 hours) operation and maintenance cost is 25 pb for A brand and 35 pb for B brand. Customers who finish their shopping come to each cash register at a speed of 10 customers per hour in accordance with the Poisson distribution. Each customer carries between 30 and 45 packages for uniform distribution Management estimates that the average cost for each customer waiting in the queue is 0.1 pb per hour. Which reader should be taken in this case? (WARNING: According to the given, service times have a general distribution and are suitable for a uniform distribution.)
