Abstract.The modern queueing theory is one of the powerful tools for a quantitative and qualitative analysis of communication systems, computer networks, transportation systems, and many other technical systems. In this paper, we deal with approximations of multiphase queueing systems (tandem queues, queues in series). Multiphase queueing systems are of special interest both in theory and in practical applications (message switching systems, processes of conveyor production, retransmission of video images, etc.). In this paper, the theorems have been proved on the law of the iterated logarithm (LIL) for departure flows of customers served under various heavy traffic conditions in multiphase queueing systems.
