Este 4-3 Modify the Exercise 4-1 check-in problem by adding agent breaks. The 16 hours are divided into two 8-hour shifts. Agent breaks are staggered (that is, one agent goes on break, and immediately upon return, the next agent goes on break, until all agents have had their breaks), starting at 90 minutes into each shift. Each agent is given one 15-minute break. Agent lunch breaks (30 minutes) are also staggered, starting 3.5 hours into each shift. The agents are rude and, if they're busy when break time comes around, they just leave anyway and make the passenger wait until break time is over before finishing up that passenger (since all agents are identical, it's not necessary for the same agent to finish up that passenger). Compare the results of this model to those of the model without agent breaks. Put a text box in your model with the numerical results requested, and repeat those same results from Exercise 4-1 in this text box for ready comparison; write a few words in your text box to address the question about comparison with Exercise 4-1. a
