We obtain explicit formulae for the steady-state distribution and the expected quality characteristics of the system. In addition, a simple recursion scheme for computing the 'orbit' busy period is proposed.engExplicit Formulae for the Characteristics of the M/H2/1 Retrial Queuejournal articlehttp://www.jstor.org/stable/2584201http://www.jstor.org/restricted access519.8Convolutive equationsHyperexponential distributionMarkov processesRetrial queuesSteady-state distributionInvestigación operativa (Matemáticas)1207 Investigación Operativa
