This paper deals with retrial queues of the |MQ/M/c/∞|- type in which the rate of input flow depends on the number of sources of repeated calls and each call has only one retrial attempt. That is, if a call fails to enter the server facility at the

We examine the effect of Top Management Team (TMT) professional finance experience on firm investment efficiency. Top managers with a career background in finance help reduce deviations of investment from the level warranted by firm fundamentals. Red

In this paper, we consider Markov models for two types of multiserver retrial queues with an input flow rate that depends on a number of calls in an orbit: classical state-dependent models and state-dependent queues with limited number of retrials. F
