摘要
This paper studies an infinite-server queue in a Markov environment, that is, an infinite-server queue with arrival rates and service times depending on the state of a Markovian background process. Scaling the arrival rates lambda(i) by a factor N, tail probabilities are examined when letting N tend to infinity; non-standard large deviations results are obtained. An importance-sampling based estimation algorithm is proposed, that is proven to be logarithmically efficient. (C) 2013 Elsevier B.V. All rights reserved.
