Entropy maximization and the busy period of some single-server vacation models
In this paper, information theoretic methodology for system modeling is applied to investigate the probability density function of the busy period in vacation models operating under the -, - and -policies. The information about the density function is limited to a few mean value constraints (usually the first moments). By using the maximum entropy methodology one obtains the least biased probability density function satisfying the system’s constraints. The analysis of the three controllable...
Entropy maximization and the busy period of some single-server vacation models
In this paper, information theoretic methodology for system modeling is applied to investigate the probability density function of the busy period in M/G/1 vacation models operating under the N-, T- and D-policies. The information about the density function is limited to a few mean value constraints (usually the first moments). By using the maximum entropy methodology one obtains the least biased probability density function satisfying the system's constraints. The analysis of the three controllable...

Estudio bayesiano de los periodos de ocupación y desocupación en una cola M/M/1/∞/FIFO en equilibrio.
En este artículo, para un modelo de colas M/M/1/∞/FIFO en equilibrio, se obtiene la distribución predictiva del tiempo de duración de un período de ocupación, y de desocupación de la cola, así como la distribución predictiva final del número de personas atendidas en un período de ocupación, y la probabilidad de que éste sea finito. Finalmente, dichos resultados se aplican en una línea de espera concreta.
Estudio del proceso de salida en un modelo D/Er/1.
En este artículo se derivan expresiones para la distribución y momentos de las variables tiempo hasta la n-ésima salida y tiempo entre salidas, en modelos de la forma D/Er/1. Se incluyen expresiones obtenidas a partir de los resultados anteriores para las distribuciones transitorias de los tiempos de salida en diferentes modelos tándem. Por último, como aplicación de los resultados se incluye un ejemplo útil para la toma de decisiones en un sistema sanitario.

Finite buffer GI/Geo/ 1 batch servicing queue with multiple working vacations
This paper analyzes a discrete-time finite buffer renewal input queue with multiple working vacations where services are performed in batches of maximum size “b”. The service times both during a regular service period and vacation period and vacation times are geometrically distributed. Employing the supplementary variable and imbedded Markov chain techniques, we derive the steady-state queue length distributions at pre-arrival, arbitrary and outside observer’s observation epochs. Based on the queue...
