Customers enter a small bank, get into a single line, are served by a teller, and finally leave the bank. Currently, this bank has one teller working from 9 a.m. to 11 a.m. Management is concerned that the wait in line seems to be too long. Therefore, it is considering two process improvement ideas: adding an additional teller during these hours or installing a new automated check-reading machine that can help the single teller serve customers more quickly. Use SimQuick to model these two processes. All the details for this model (as well as many others) appear in the book SimQuick: Process Simulation with Excel, which is included, along with the SimQuick software, in MyLab Operation Management.
