The greatest variation of and depended on the level of system utilisation of exponential service-times, more than the system capacity and the number of servers; meanwhile, for systems having heavy-tailed service-times, it was the k parameter which determined the magnitude of the variation i.e. convergence of the median and/or variance Tables 1 and 2
Las mayores variaciones de Lpy Wpdependen del nivel de utilización de los sistemas con tiempos de servicio exponenciales, más que de la capacidad del sistema y el número de servidores;
