Translated Renewal Processes and the Existence of a Limiting Distribution for the Queue Length of the GI/G/s Queue

Some ideas from the theory of weak convergence of probability measures on function spaces are modified and extended to show that the queue-length of the GI/G/s system converges in distribution as time passes, for the case of atomless interarrival and service distributions. The key to this result is the concept of the uniform σ-additivity of certain sets of renewal measures on a space endowed with incompatible topology and σ-field.
