Summary :

This paper presents an analysis for a multi-server system with batch arrivals of queueing and non-queueing types of customers. Customers of two types are assumed to arrive in two independent batch Poisson streams and to have exponentially distributed service times. This situation can be seen in the Facsimile Intelligent Communication System (FICS). The existing studies on the service systems which dealt with two types of customers, however, were limited to the case of Poisson arrivals. By using the generating function technique, a recursive scheme for the steady-state probabilities in the system is obtained. Traffic measures, e.g., loss probability, mean waiting time, and the probability that the number of customers in the system is zero, are deduced without any truncated error. It is shown that the above-mentioned traffic measures can be represented by only a finite set of the steady-state probabilities in spite of the infinite state space. In some special cases, it is seen that the results obtained here are consistent with the previous works. Numerical examples are shown and traffic characteristics are also discussed.
