Specifically, we propose a recursive scheme to compute the probability function of the number of customer losses in busy-periods of such systems. The effectiveness and usefulness of the proposed method is illustrated through the presentation of numerical examples that consider different arrival rates and service time and group size distributions.engBusy-periodCustomer lossesMarkov regenerative processesNon-preemptive systemsOscillating queuesPreemptive systemsjournal article10.1016/j.cor.2020.1051801873-765X
