Consider the checkout process of a grocery store with ten identical cashiers performing the checkout process. First, assume that each cashier has her own separate checkout queue and that customers arrive at each case with an average arrival rate of 12 per hour. It takes 4.8 minutes on average to check a customer out. Assume that both the inter-arrival times and service times have a coefficient variation of 1. 1) How long on average does a customer wait from joining the queue in front of a cashier until her checkout is complete? 2) On average, how many customers are waiting in the queue in total? ( Including all queues)? 3) Now suppose the ten queues are pooled tog

Assume that you are a cashier and your manager requires that you immediately enter each sale when it occurs. Recently, lunch hour traffic has increased and the assistant manager asks you to avoid delays by taking customers’ cash and making change without entering sales. The assistant manager says she will add up cash and enter sales after lunch. She says that, in this way, customers will be happy and the register record will always match the cash amount when the manager arrives at three o’clock. The advantages to the process proposed by the assistant manager include improved customer service, fewer delays, and less work for you. The disadvantage is that the assistant manager could steal cash by simply recording less sales than the cash received and then pocketing the excess cash. You decide to reject her suggestion without the manager’s approval and to confront her on the ethics of her suggestion. Required Propose and evaluate two other courses of action you might consider, and explain…
