Suppose a supermarket uses a system in which allcustomers wait in a single line for the first available cashier.Assume that the service time for a customer who purchasesk items is exponentially distributed, with mean k seconds.Also, a customer who purchases k items feels that the costof waiting in line for 1 minute is $k1. If customers can beassigned priorities, what priority assignment will minimizethe expected waiting cost incurred by the supermarket’scustomers? Why would a customer’s waiting cost per minutebe a decreasing function of k?
