Moments of losses during busy-periods of regular and nonpreemptive oscillating MX/G/1/n. Ann Oper Res 252, 191–211 (2017). https://doi.org/10.1007/s10479-015-1901-x0254-53301572-9338http://hdl.handle.net/10400.8/13754This work addresses loss characteristics associated to busy-periods of regular and nonpreemptive oscillating M X /G/1/n systems. By taking advantage of the Markov regenerative structure of the number of customers in the system and resorting to results on moments of compound mixed Poisson distributions, it proposes a fast and easy to implement recursive procedure to compute integer moments of the number of customers lost in busy periods initiated with multiple customers in the system.engBatch arrivalsOscillating systemBusy-periodsCustomer lossesMomentsCompound mixed-Poissonjournal article10.1007/s10479-015-1901-x
