    Rare-event simulation for tandem queues: A simple and efficient importance sampling scheme

    No full text
    This paper focuses on estimating the rare event of overflow in the downstream queue of a tandem Jackson queue, relying on importance sampling. It is known that in this setting ‘traditional’ state-independent schemes perform poorly. More sophisticated state-dependent schemes yield asymptotic efficiency. Their drawback, however, is that they require a per-state computation of the new measure, so that it still consumes considerable machine time. The contribution of this paper is a scheme that combines asymptotic efficiency with low complexity. It retains the quality of the original state-dependent scheme, but its implementation is almost as simple as for state-independent analogues
