Abstract:

This paper presents a method for calculating steady state probabilities of M/Er/c/K queueing systems. The infinitesimal generator matrix is used to define all possible states in the system and their transition probabilities. While this matrix can be written down immediately for many other M/PH/c/K queueing systems with phase-type service times (e.g. Coxian, Hypoexponential, …), it requires a more careful analysis for systems with Erlangian service times. The constructed matrix may then be used to calculate steady state probabilities using an iterative algorithm.
