    The approximations study of performance measures in multi-class queues was presented. The Markovian multi-class queues under study were with preemptive priorities. The queues approximations for large problems were based on class aggregation and server reduction techniques. The obtained approximations were compared with the simulation results to their exactness for yielding small-to-moderate approximation errors.
