Abstract
This paper is analyses one of the closed multiple classes queueing networks model by using the discrete review policies. The size of the batches are selected in the network according to discrete positive Poisson distribution and are served according to Exponential distribution. Our aim is to obtain model performance measures when the number of jobs in the system is fixed, the generating parameter of service times changes and also when the generating parameter of service times is fixed, The number ofjobs in the system changes. Finally, We calculate the efficiency measures of the network by using discrete-review policy results through an example.
