Create a paper clip assembly line. A worker at the first station assembles two small paper clips. A worker at the second station adds one larger paper clip. One student feeds the first station with two paper clips at random intervals. Another student observes the line to note the utilization of the stations, the number of assemblies in the inter-station buffer, and the number of completed assemblies. Run the assembly line for 2 minutes. Discuss how this exercise is like a simulation model and experiment.
