A large box store has six self$-$checkout servers. Customers join a single line andthe person in front of the line joins the first available server. Observationally, it has beennoted that this line is frequently very, very long and it may discourage some customers fromusing the self$-$checkout. The general manager often shops at another store that also hasself$-$checkout, but each checkout has its own line. She has observed that the lines at thatplace never seem to be excessively long and would like to study if replacing the single linewith six multiple lines would improve customer experiences. She has, of course, turned toyou to better understand this issue. There is ample floor space to implement eitherapproach, so this is not a consideration. The focus of your analysis should be on measuresthat customers might consider important.You have already collected some data on both customer arrivals to self$-$service stations and the customer service time.a$.$ Use the available data to formulate an appropriate model for each option.b$.$ Implement the models to evaluate all customer centric performance measures.Choose at least two metrics that you consider to be key and explain why they are important.c$.$ Report any trade$-$offs between the two options and make a recommendation to the store manager. Your recommendation should include your estimates of how the selected key performance measures would change if the system were to be reconfigured.
