Abstract

The M^x/G/1 queue without server vacations, with multiple vacations is studied under the LIFO service regime. For each model we derive explicit formulae for the Laplace-Stieltjes transform, mean and second moment of the waiting time W"L"I"F"O of an arbitrary customer, and extend the range of Fuhrmann's general result, showing directly that for each case, E[W"L"I"F"O^2] = E[W"F"I"F"O^2]/(1 - @r).
