EP2930 Queuing Theory 7.5 credits


After completion of the course the student should be able to

  • define and explain basic concepts in the theory Markov processes, M/M/m, M/M/m/K and M/M/m/K/C queueing systems
  • derive and apply main formulas for some properties (such as stationary probabilities, average waiting and system time, expected number of customers in the que, etc. ) of M/M/m, M/M/m/K and M/M/m/K/C queueing systems.
  • to calculate the traffic intensity, blocked traffic and the utilization of some queueing systems
  • solve some simple problems on queueing networks
  • analyze and solve problems using computer aid (Maple, Matlab or Mathematica).
