The Simulation and Minimization of Loss Probability in the Tandem Queueing with Two Heterogeneous Channels

Abstract

A stochastic model consisting of two heterogeneous channels and having no waiting room in front of each is considered. A customer who has completed his service in channel 1 while channel 2 is busy blocks channel 1 with probability Q or leaves the system with 1 - Q probability. This model was analysed: expected number of customer and loss probability of customer are calculated and optimal ordering of channels minimizing parameters has been found. Additionally, this model was simulated; furthermore, simulated and exact results of loss probabilities of customers were given in the tables. © 2013 Müjgan Zobu et al.
