We refer to a busy period and present a detailed computational analysis of four new performance measures: (i) the successful retrials, (ii) the blocked retrials, (iii) the successful primary arrivals, and (iv) the blocked primary arrivals.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0096300307002068http://www.sciencedirect.com/restricted access517.9NumberMarkov queuing systemBlocked arrivalsMeanCovarianceGenerating functionHidden queueAlgorithmsMomentsProbability mass functionNumerical examplesEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
