Boundedness on stochastic Petri nets.

J. Campos, F. Plo, M. San Miguel (1993)

Revista Matemática de la Universidad Complutense de Madrid

Stochastic Petri nets generalize the notion of queuing systems and are a useful model in performance evaluation of parallel and distributed systems. We give necessary and sufficient conditions for the boundedness of a stochastic process related to these nets.

Cálculo del número medio de máquinas activas en un grupo de un operario y N máquinas, con incidencias poissonianas y tiempos de servicio aleatorio.

Albert Corominas Subias (1988)

Qüestiió

Este artículo expone un método para el cálculo del número medio de máquinas en funcionamiento en un sistema formado por un operario y N máquinas iguales, con tiempos exponenciales de funcionamiento entre averías y tiempos de servicio aleatorios, idéntica e independientemente distribuidos. El modelo generaliza las conocidas fórmulas que se obtienen a partir de los modelos M/M/1 con centro emisor finito y de Ashcroft, que suelen utilizarse para el problema de asignación de máquinas.

Characterization of the departure process from an ME/ME/1 queue

Jayesh Kumaran, Kenneth Mitchell, Appie Van de Liefvoort (2004)

RAIRO - Operations Research - Recherche Opérationnelle

In this paper we propose a family of finite approximations for the departure process of an ME/ME/1 queue indexed by a parameter k defined as the system size of the finite approximation. The approximations capture the interdeparture times from an ME/ME/1 queue exactly and preserve the lag correlations of inter-event times of the departures from an ME/ME/1 queue up to lag ( k - 1 ) .

The approximations capture the interdeparture times from an ME/ME/1 queue exactly and preserve the lag correlations of inter-event times of the departures from an ME/ME/1 queue up to lag (k - 1).

Computation of the limiting distribution in queueing systems with repeated attempts and disasters

J. R. Artalejo, A. Gómez-Corral (2010)

RAIRO - Operations Research

Single server queues with repeated attempts are useful in the modeling of computer and telecommunication systems. In addition, we consider in this paper the possibility of disasters. When a disaster occurs, all the customers present in the system are destroyed immediately. Using a regenerative approach, we derive a numerically stable recursion scheme for the state probabilities. This model can be employed to analyze the behaviour of a buffer in computers with virus infections.
