Problem description The problem at hand relates to a waiting time management of queues in a typical bank. In a bid to improve the level of service at the tellers, a bank manager seeks to find strategies to employ for better service offering that will improve customer satisfaction. The manager is prepared to employ up to 5 cashiers, but not less than 1. The main managernent objectives are (i) To have a average customer to wait less than 2 minutes for service, and (ii) the average length of the queue (waiting line) to be 2 persons or fewer. The manager tests two models to help in the decision process. Model 2 Suppose the manager uses empirical data collected from past observations, from which it is estimated that the bank serves 150 customers per day, and existing arrival and service times are as given in the tables below: Table 1: Arrival times Question 2 Determine if this customer service level in Model 2 is satisfactory according to the manager guidelines/objectives. If not, determine, through modelling, the minimal changes for tellers required to accomplish the manager's goal
