Abstract
Calls for service arrive at an infinite-server queue according to a mixture of Poisson processes. Service for each process occurs in a number of independent stages; stages are identified by the number of emergency units busy serving the call. Assuming arbitrary finite-mean service-time distributions, the distribution of the number of busy units at any time is determined, and the approach to a steady-state distribution is proved.
