CDA6530: Performance Models of Computers and Networks (Fall 2011) Project 4: Discrete Event Simulation (Assigned 11/08; due: 11/18 midnight; late submission by 11/23 midnight with 15 points off) In this project, you will need to use discrete event simulation approach I introduced in class to simulate the traditional “machine-repairman” closed queuing network. Please check “examples” lecture notes (lecture 13) Page 2-5 for the machine-repairman problem description. Assume that there are c=3 machines, failing rate 2 . 0 = λ /min, the repair rate 5 . 0 = μ /min. That is to way, each machine works for an exponential distributed time with rate 2 . 0 = λ /min before it fails, and the repairmen takes an exponential distributed time with rate 5 . 0 = μ /min to finish repairing a failed machine. If there are more than one failed machines, the repairman uses “first come, first serve” to repair failed machines. For discrete event simulation, define system state N(t) as the number of working machines at time t.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
