Abstract
We extend our studies of sample‐path stability to multiserver input‐output processes with conditional output rates that may depend on the state of the system and other auxiliary processes. Our results include processes with countable as well as uncountable state spaces. We establish rate stability conditions for busy period durations as well as the input during busy periods. In addition, stability conditions for multiserver queues with possibly heterogeneous servers are given for the workload, attained service, and queue length processes. The stability conditions can be checked from parameters of primary processes, and thus can be verified a priori. Under the rate stability conditions, we provide stable versions of Little′s formula for single server as well as multiserver queues. Our approach leads to extensions of previously known results. Since our results are valid pathwise, non‐stationary as well as stationary processes are covered.
