Anyone who has ever waited in a line knows just how tedious it can be. Dr. Edward Sullivan, associate professor of business administration and economics, and Lauren Throne ’10 analyzed the waiting line problem for a coffee kiosk, formerly known as Cup O’Joe, on the campus of Lebanon Valley College. This faculty-student research project grew out of Sullivan’s Management Science course (BUS 383), where he teaches queuing (waiting) line models. Using observations collected at the site, Sullivan and Throne examined the flow of customers and fitted several waiting line models to the data to determine the economic efficiency of several systems. The study determined that the waiting line model adopted by the business was the most economically efficient system to use given their customer flow. However, while determining that the addition of second cashier would cut waiting time by half; the added cost could not be financially justified.
