1. Professor Nutty holds office hours everyday to answer students’ questions. Students arrive at an average rate of 10 per hour. Assume that arrivals are Poisson distributed. Professor Nutty can process students at an average rate of 12 per hour. Assume that the time each student takes is exponentially distributed. What is the average number of students waiting outside Professor Nutty’s office and how long do they wait on an average? Professor Nutty is concerned that students wait too long. As a remedy, he asks his TA to help him during his office hours. The TA is also able to advise students at the rate of 12 per hour. Students queue at the professor’s office and are answered by whoever becomes available when it’s their turn. What is the average number of students waiting outside Professor Nutty’s office and how long do they wait on an average? This is an M/M/2 queue. We need to find Lq for s = 2 and λ / μ =0.833.
